+Este es el Contrato de licencia de la versión preliminar del SDK de Android (el “Contrato de licencia”). 1.
+
+ Introducción 1.1 Se le otorga la licencia de la versión preliminar del SDK de Android (denominada “Versión preliminar” en este Contrato de licencia y que incluye específicamente los archivos de sistema de Android, las API agrupadas y los archivos de biblioteca de la Versión preliminar, si se encuentran disponibles), sujeto a los términos del Contrato de licencia.
+
+ El Contrato de licencia establece una relación legal vinculante entre usted y Google en relación con el uso que usted realice de la Versión preliminar. 1.2 “Android” hace referencia al conjunto de soluciones Android para dispositivos, según se encuentre disponible en el Proyecto de código abierto de Android (Android Open Source Project), que se encuentra en la siguiente URL: http://source.android.com/, y según se actualiza periódicamente. 1.3 “Google” hace referencia a Google Inc., una corporación de Delaware, con sede principal en 1600 Amphitheatre Parkway, Mountain View, CA 94043, Estados Unidos. 2.
+
+
+
+
+
+ Aceptación del Contrato de licencia 2.1 Para poder utilizar la Versión preliminar, primero debe aceptar el Contrato de licencia.
+
+ Si no acepta el Contrato de licencia, no podrá utilizar la Versión preliminar. 2.2 Al hacer clic para aceptar o utilizar la Versión preliminar, por medio del presente, usted acepta los términos del Contrato de licencia. 2.3 Usted no puede utilizar la Versión preliminar ni aceptar el Contrato de licencia si tiene prohibido recibir la Versión preliminar en virtud de las leyes de los Estados Unidos o de otros países, lo que incluye el país donde es residente o desde el que utilizará la Versión preliminar. 2.4 Si usted utilizará la Versión preliminar de forma interna, dentro de su compañía u organización, usted acepta quedar sujeto al Contrato de licencia en representación de su empleador u otra entidad, y expresa y garantiza que tiene plena autoridad legal para vincular a su empleador o a dicha entidad al Contrato de licencia.
+
+
+
+
+
+ Si no posee la autoridad exigida, no podrá aceptar el Contrato de licencia ni usar la Versión preliminar en representación de su empleador u otra entidad. 3.
+
+ Licencia de la Versión preliminar de Google 3.1 Sujeto a los términos del Contrato de licencia, Google le otorga una licencia libre de regalías, no asignable, no exclusiva, no transferible a terceros, limitada y revocable para utilizar la Versión preliminar, de forma personal o interna dentro de su compañía u organización, únicamente para desarrollar aplicaciones para ejecutar en la plataforma de Android. 3.2 Usted acepta que Google u otros terceros poseen todos los derechos legales, títulos e intereses en relación con la Versión preliminar, incluidos los Derechos de propiedad intelectual que existan en la Versión preliminar.
+
+
+
+ Los “Derechos de propiedad intelectual” hacen referencia a todos y cada uno de los derechos en virtud de las leyes de patentes, derechos de autor, secreto comercial y marca comercial, y todos los demás derechos de propiedad. Google se reserva todos los derechos que no se le otorguen expresamente. 3.3 No podrá utilizar la Versión preliminar para ningún otro propósito que no esté expresamente permitido en el Contrato de licencia.
+
+ Excepto en la medida que lo exijan las licencias correspondientes de terceros, no podrá: (a) copiar (excepto con fines de copia de seguridad), modificar, adaptar, redistribuir, descompilar, utilizar técnicas de ingeniería inversa, desarmar ni crear trabajos derivados de la Versión preliminar ni de ninguna de sus partes; ni (b) cargar ninguna parte de la Versión preliminar en un teléfono móvil ni en ningún otro dispositivo de hardware (a excepción de una computadora personal), ni podrá combinar ninguna parte de la Versión preliminar con otro software, ni distribuir algún software o dispositivo que incorpore alguna parte de la Versión preliminar. 3.4 Usted acepta que no tomará medidas que pudieran provocar la fragmentación de Android, incluidas, entre otras, la distribución y la participación en la creación o la promoción de un kit de desarrollo de software derivado de la Versión preliminar. 3.5 El uso, la reproducción y la distribución de los componentes de la Versión preliminar con licencia de software de código abierto están regidos exclusivamente por los términos de la licencia de ese software de código abierto y no de este Contrato de licencia.
+
+
+
+ Usted acepta mantener la licencia en buenas condiciones con respecto a dichas licencias de software de código abierto en virtud de todos los derechos otorgados y acepta abstenerse de realizar alguna acción que pueda poner fin, suspender o violar dichos derechos. 3.6 Usted acepta que la forma y la naturaleza de la Versión preliminar que proporciona Google pueden cambiar sin brindarle aviso previo y que las versiones futuras de la Versión preliminar pueden ser incompatibles con las aplicaciones desarrolladas en versiones anteriores de la Versión preliminar.
+
+ Usted acepta que Google puede (de forma permanente o temporal) dejar de proporcionarles la Versión preliminar (o cualquiera de las características incluidas en ella) a usted o a los usuarios, generalmente, a criterio exclusivo de Google, sin brindarle aviso previo. 3.7 Ninguna declaración de este Contrato de licencia le otorga el derecho de utilizar alguno de los nombres comerciales, las marcas comerciales, las marcas de servicio, los logotipos, los nombres de dominio ni otras características distintivas de marca de Google. 3.8 Usted acepta que no eliminará, ocultará ni alterará ninguno de los avisos de derechos de propiedad (lo que incluye los avisos de marca comercial y derechos de autor) que pudieran estar anexados o incluidos en la Versión preliminar. 4.
+
+
+
+
+
+ Uso que usted realiza de la Versión preliminar 4.1 Google acepta que ninguna declaración del Contrato de licencia le concede a Google derecho, título o interés alguno de su parte (o de parte de sus licenciantes), en virtud del Contrato de licencia, con respecto a las aplicaciones de software que usted desarrolle mediante el uso de la Versión preliminar, lo que incluye los derechos de propiedad intelectual que conlleven esas aplicaciones. 4.2 Usted acepta utilizar la Versión preliminar y escribir aplicaciones únicamente conforme a lo que permite (a) este Contrato de licencia y (b) las leyes, regulaciones, o prácticas y pautas generalmente aceptadas pertinentes en las jurisdicciones relevantes (lo que incluye las leyes sobre la exportación de datos o software hacia los Estados Unidos u otros países relevantes y desde ellos). 4.3 Usted acepta que si utiliza la Versión preliminar para desarrollar aplicaciones, protegerá la privacidad y los derechos legales de los usuarios.
+
+
+
+
+
+ Si los usuarios le proporcionan sus nombres de usuario, contraseñas u otra información de inicio de sesión o información personal, debe comunicarles a los usuarios que la información se encontrará disponible para su aplicación, y debe proporcionarles a dichos usuarios un aviso de privacidad con protección y validez legal. Si su aplicación almacena información personal o confidencial proporcionada por los usuarios, lo debe hacer de forma segura. Si los usuarios le proporcionan información sobre la cuenta de Google, su aplicación solo puede usar esa información para acceder a la cuenta de Google del usuario siempre que este le haya otorgado permiso para hacerlo y con los fines para los que se lo haya otorgado. 4.4 Usted acepta que no participará en ninguna actividad con la Versión preliminar (lo que incluye el desarrollo o la distribución de una aplicación) que interfiera, interrumpa, dañe o acceda sin autorización a servidores, redes u otras propiedades o servicios de Google o de algún tercero. 4.5 Usted acepta que es el único responsable (y que Google no asume responsabilidades hacia usted ni terceros) de los datos, el contenido o los recursos que usted cree, transmita o muestre a través de Android o las aplicaciones para Android, y de las consecuencias de sus acciones (lo que incluye la pérdida o el daño que Google pudiera sufrir) al hacerlo. 4.6 Usted acepta que es el único responsable (y que Google no asume responsabilidades hacia usted ni terceros) de cualquier incumplimiento de sus obligaciones en virtud de este Contrato de licencia, los contratos aplicables de terceros o los términos del servicio, o cualquier ley o regulación pertinentes, y de las consecuencias (lo que incluye las pérdidas o los daños que pudieran sufrir Google o algún tercero) de dichos incumplimientos. 4.7 La Versión preliminar se encuentra en desarrollo, y sus pruebas y comentarios son una parte importante del proceso de desarrollo.
+
+
+
+
+
+
+
+ Al utilizar la Versión preliminar, usted reconoce que la implementación de algunas características aún se encuentra en desarrollo y que no debe confiar en que la Versión preliminar contará con todas las funcionalidades de una versión estable. Usted acepta no distribuir públicamente ni enviar ninguna aplicación que utilice esta Versión preliminar, ya que esta Versión preliminar ya no se admitirá tras el lanzamiento del SDK oficial de Android. 5.
+
+ Sus credenciales de desarrollador 5.1 Usted acepta que es responsable de mantener la confidencialidad de toda credencial de desarrollador que Google pudiera otorgarle o que usted pudiera escoger, y que será el único responsable de todas las aplicaciones que se desarrollen con sus credenciales de desarrollador. 6.
+
+
+
+ Privacidad e información 6.1 A fin de poder innovar y mejorar de forma continua la Versión preliminar, Google podría recopilar ciertas estadísticas de uso del software, lo que incluye, entre otras características, un identificador único, la dirección IP asociada, el número de versión del software e información sobre las herramientas o los servicios de la Versión preliminar que se estén utilizando y la manera en que se estén utilizando.
+
+ Antes de que se recopile esta información, la Versión preliminar se lo notificará y le solicitará su permiso. Si no otorga su permiso, no se recopilará la información. 6.2 Los datos recopilados se analizan en el agregado para mejorar la Versión preliminar y se conservan de acuerdo con la política de privacidad de Google que se encuentra en el sitio http://www.google.com/policies/privacy/. 7.
+
+
+
+ Aplicaciones de terceros 7.1 Si utiliza la Versión preliminar para ejecutar aplicaciones desarrolladas por un tercero o que accedan a datos, contenido o recursos proporcionados por un tercero, usted acepta que Google no es responsable de esas aplicaciones, datos, contenido ni recursos.
+
+ Usted comprende que todos los datos, contenidos o recursos a los que podría acceder a través de esas aplicaciones de terceros son exclusiva responsabilidad de la persona que los origina y que Google no es responsable de las pérdidas ni los daños que usted pudiera experimentar como consecuencia del uso o acceso de cualquiera de esas aplicaciones, datos, contenido o recursos de terceros. 7.2 Usted debe saber que los datos, el contenido y los recursos que se le presentan a través de esa aplicación de un tercero pueden estar protegidos por derechos de propiedad intelectual que les pertenecen a sus proveedores (o a otras personas o compañías en representación de estos).
+
+ No puede modificar, alquilar, arrendar, prestar, vender, distribuir ni crear obras derivadas basadas en esos datos, contenidos o recursos (en su totalidad o en parte), a menos que los propietarios pertinentes le hayan otorgado permiso específicamente para hacerlo. 7.3 Usted acepta que el uso que haga de las aplicaciones, los datos, el contenido o los recursos de ese tercero puede estar sujeto a términos independientes entre usted y el tercero correspondiente. 8.
+
+
+
+ Uso de las API de Google 8.1 API de Google 8.1.1 Si utiliza alguna API para recuperar datos de Google, usted acepta que los datos pueden estar protegidos por derechos de propiedad intelectual que le pertenecen a Google o a las partes que proporcionan esos datos (o a otras personas o empresas en representación de estos).
+
+
+
+ El uso que realice de cualquiera de esas API puede estar sujeto a términos de servicio adicionales. No puede modificar, alquilar, arrendar, prestar, vender, distribuir ni crear obras derivadas basadas en esos datos (en su totalidad o en parte), a menos que los términos de servicio correspondientes lo permitan. 8.1.2 Si utiliza alguna API para recuperar datos de un usuario de Google, usted acepta y acuerda que solo podrá recuperar datos con el consentimiento explícito del usuario y solo con los fines limitados para los que el usuario le haya otorgado permiso para hacerlo. 9.
+
+
+
+ Finalización del Contrato de licencia 9.1 Este Contrato de licencia tendrá vigencia hasta que lo revoquen usted o Google, como se indica a continuación. 9.2 Si desea rescindir el Contrato de licencia, puede hacerlo al interrumpir el uso que realiza de la Versión preliminar y de las credenciales de desarrollador pertinentes. 9.3 Google puede, en cualquier momento, rescindir el Contrato de licencia, con causa o sin ella, después de notificárselo a usted. 9.4 El Contrato de licencia finalizará automáticamente, sin previo aviso ni acción alguna, tras la primera de las siguientes situaciones: (A) cuando Google deje de proporcionar la Versión preliminar o ciertas partes de esta a los usuarios en el país donde usted reside o desde el que utiliza el servicio; y (B) cuando Google emita una versión final del SDK de Android. 9.5 Si el Contrato de licencia se rescinde, se revocará la licencia que usted recibió en virtud de dicho contrato; usted deberá suspender inmediatamente todo uso de la Versión preliminar y las disposiciones de los párrafos 10, 11, 12 y 14 seguirán vigentes indefinidamente. 10.

+
+
+
+
+
+
+
+
+ EXENCIONES DE RESPONSABILIDAD 10.1 USTED COMPRENDE Y ACEPTA EXPRESAMENTE QUE EL USO QUE REALICE DE LA VERSIÓN PRELIMINAR ES BAJO SU PROPIO RIESGO Y QUE LA VERSIÓN PRELIMINAR SE PROPORCIONA “EN LAS CONDICIONES EN LAS QUE SE ENCUENTRA” Y “SUJETA A DISPONIBILIDAD” SIN GARANTÍAS DE NINGÚN TIPO POR PARTE DE GOOGLE. 10.2 EL USO QUE USTED REALICE DE LA VERSIÓN PRELIMINAR Y DE TODO MATERIAL DESCARGADO U OBTENIDO DE ALGUNA OTRA MANERA MEDIANTE EL USO DE LA VERSIÓN PRELIMINAR ES A SU ENTERO RIESGO Y DISCRECIÓN, Y USTED ES EL ÚNICO RESPONSABLE DE CUALQUIER DAÑO QUE PUDIERA SUFRIR SU SISTEMA INFORMÁTICO U OTRO DISPOSITIVO, O DE LA PÉRDIDA DE DATOS COMO CONSECUENCIA DE DICHO USO.
+
+
+
+ SIN PERJUICIO DE LO MENCIONADO ANTERIORMENTE, USTED COMPRENDE QUE LA VERSIÓN PRELIMINAR NO ES UNA VERSIÓN ESTABLE, Y PUEDE CONTENER ERRORES, DEFECTOS Y VULNERABILIDADES DE SEGURIDAD QUE PUEDEN PROVOCAR DAÑOS SIGNIFICATIVOS, LO QUE INCLUYE LA PÉRDIDA COMPLETA E IRRECUPERABLE DEL USO DE SU SISTEMA INFORMÁTICO U OTRO DISPOSITIVO. 10.3 GOOGLE TAMBIÉN RECHAZA TODAS LAS GARANTÍAS Y CONDICIONES DE CUALQUIER TIPO, EXPRESAS O IMPLÍCITAS, INCLUIDAS, ENTRE OTRAS, LAS GARANTÍAS Y CONDICIONES DE COMERCIABILIDAD, IDONEIDAD PARA UN FIN DETERMINADO Y NO VIOLACIÓN. 11.
+
+
+
+ LIMITACIÓN DE RESPONSABILIDADES 11.1 USTED COMPRENDE Y ACEPTA EXPRESAMENTE QUE GOOGLE, SUS SUBSIDIARIAS Y FILIALES, Y SUS LICENCIANTES NO SERÁN RESPONSABLES ANTE USTED, EN VIRTUD DE NINGUNA TEORÍA DE RESPONSABILIDAD, POR NINGÚN DAÑO DIRECTO, INDIRECTO, INCIDENTAL, ESPECIAL, RESULTANTE NI PUNITIVO EN EL QUE PODRÍA HABER INCURRIDO, LO QUE INCLUYE LA PÉRDIDA DE DATOS, YA SEA QUE SE LE HAYA NOTIFICADO O NO A GOOGLE O A SUS REPRESENTANTES, O SOBRE CUYA POSIBILIDAD ESTOS DEBERÍAN HABER SABIDO. 12.
+
+
+
+ Indemnización 12.1 Hasta el grado máximo que permita la ley, usted acepta defender, indemnizar y eximir de responsabilidades a Google, sus filiales y sus respectivos directores, funcionarios, empleados y agentes, de todo tipo de reclamo, acción legal y proceso judicial, así como de las pérdidas, responsabilidades, daños, costos y gastos (incluidos los honorarios razonables de abogados) que surjan o se acumulen (a) del uso que usted realiza de la Versión preliminar, (b) de cualquier aplicación que desarrolle en la Versión preliminar que infrinja algún derecho de propiedad intelectual de cualquier persona, o que difame a cualquier persona o viole sus derechos de publicidad o privacidad, y (c) del incumplimiento por su parte del Contrato de licencia. 13.
+
+
+
+ Cambios en el Contrato de licencia 13.1 Google puede realizar cambios en el Contrato de licencia a medida que distribuye nuevas versiones de la Versión preliminar.
+
+ Cuando se realicen esos cambios, Google emitirá una nueva versión del Contrato de licencia, que estará disponible en el sitio web donde se ponga a la venta la Versión preliminar. 14.
+
+ Términos legales generales 14.1 El Contrato de licencia constituye el contrato legal integral entre usted y Google, y rige el uso que usted realice de la Versión preliminar (a excepción de los servicios que Google pueda proporcionarle en virtud de un contrato por escrito independiente), y reemplaza totalmente cualquier contrato anterior entre usted y Google en relación con la Versión preliminar. 14.2 Usted acepta que, si Google no ejerce ni impone un derecho o recurso legal especificados en el Contrato de licencia (o sobre el que Google tenga beneficios conforme a cualquier ley aplicable), esto no se considerará una renuncia formal a los derechos por parte de Google y Google aún seguirá recibiendo los beneficios de esos derechos o recursos legales. 14.3 Si algún tribunal judicial con jurisdicción para decidir sobre este asunto determina que alguna de las disposiciones de este Contrato de licencia no es válida, se eliminará esa disposición del Contrato de licencia sin que eso afecte la validez del resto del contrato.
+
+
+
+
+
+ Las disposiciones restantes del Contrato de licencia continuarán siendo válidas y aplicables. 14.4 Usted reconoce y acepta que cada miembro del grupo de compañías de las que Google es la compañía central serán terceros beneficiarios del Contrato de licencia, y que esas otras empresas tendrán el derecho de imponer directamente cualquier disposición y ampararse en las disposiciones de este Contrato de licencia que les confieran un beneficio (o que confieran derechos a su favor).
+
+ Además de esto, ninguna otra persona o compañía serán terceros beneficiarios del Contrato de licencia. 14.5 RESTRICCIONES DE EXPORTACIÓN.
+
+ LA VERSIÓN PRELIMINAR ESTÁ SUJETA A LAS LEYES Y REGULACIONES DE EXPORTACIÓN DE LOS ESTADOS UNIDOS. DEBE CUMPLIR CON TODAS LAS LEYES Y REGULACIONES DE EXPORTACIÓN NACIONALES E INTERNACIONALES QUE SE APLIQUEN A LA VERSIÓN PRELIMINAR. ESTAS LEYES INCLUYEN RESTRICCIONES EN RELACIÓN CON LOS DESTINOS, USUARIOS FINALES Y USO FINAL. 14.6 Usted no puede asignar ni transferir el Contrato de licencia sin la aprobación previa por escrito de Google y todo intento de asignación sin dicha aprobación no tendrá validez.
+
+ No podrá delegar sus responsabilidades u obligaciones otorgados en virtud del Contrato de licencia sin la aprobación previa por escrito de Google. 14.7 El Contrato de licencia y su relación con Google conforme al Contrato de licencia se regirán por las leyes del estado de California, independientemente de los principios de conflictos entre leyes.
+
+ Usted y Google aceptan presentarse ante la jurisdicción exclusiva de los tribunales del condado de Santa Clara, California, para resolver cualquier asunto legal que pudiera surgir del Contrato de licencia. Sin perjuicio de esto, usted acepta que Google aún podrá aplicar reparaciones conforme a mandato judicial (o a un tipo equivalente de desagravio legal) en cualquier jurisdicción.

+
+    <div class="sdk-terms" onfocus="this.blur()" style="width:678px">
+以下は、Android SDK Preview の使用許諾契約です（以下「本契約」）。
+
+1.はじめに
+
+1.1 Android SDK Preview（以下、本契約で「Preview」という。具体的には利用可能な場合には Android システム ファイル、パッケージ型 API、Preview ライブラリ ファイルを含む）は、本契約の規定に従ってライセンス許可されます。本契約では、デベロッパーの Preview の使用に関して、デベロッパーと Google の間で法的拘束力のある契約を結びます。
+
+1.2 「Android」とは、Android オープン ソース プロジェクト（http://source.android.com/ にて随時更新）にて利用可能な、端末向けの Android ソフトウェア スタックを意味します。
+
+1.3 「Google」とは、1600 Amphitheatre Parkway, Mountain View, CA 94043, United States に主たる事業所を有するデラウェア州法人である Google Inc. を意味します。
+
+2.本契約の同意
+
+2.1 Preview を使用するには、まず本契約に同意する必要があります。本契約に同意しない場合は Preview を使用できません。
+
+2.2 同意するかまたは Preview を使用するためにクリックすると、本契約に同意したことになります。
+
+2.3 米国またはその他の国（デベロッパーが居住している国かまたはデベロッパーが Preview を使用する国を含む）の法律により Preview の使用を禁止されている人である場合、Preview を使用することも、使用許諾契約に同意することもできません。
+
+2.4 雇用主またはその他の事業体を代表または代理して本契約に拘束されることに同意し Preview を企業または組織の内部で使用する場合、担当者の雇用主またはその他の事業体を本契約に法的に拘束する完全な法的権限を有していることを表明および保証するものとします。担当者が必要な権限を有していない場合は、担当者の雇用主またはその他の事業体を代表または代理して、本契約に同意することも、Preview を使用することもできません。
+
+3.Google Preview ライセンス
+
+3.1 本契約の規定に従い、Google は Android プラットフォーム上で実行するアプリケーションの開発に Preview を個人的にもしくは企業または組織の内部で使用するための、ロイヤリティ フリーな、譲渡不可で、非排他的な、サブライセンス不可の、限定された、取り消し可能なライセンスを付与するものとします。
+
+3.2 Preview に関するすべての法的権利、所有権、利益（Preview に含まれる知的財産権を含む）は Google またはサードパーティが所有するものとします。「知的財産権」とは、特許法、著作権法、営業秘密法、商標法、不当競争防止法に基づいて発生するすべての権利、およびその他のすべての所有権を意味します。デベロッパーに明示的に付与されていない権利は、すべて Google が所有します。
+
+3.3 本契約で明示的に許可されている目的以外においては、Preview を使用できません。当該のサードパーティのライセンスで必要とされる場合を除き、デベロッパーは、（a） Preview または Preview の一部をコピー（バックアップ目的を除く）、修正、改造、再配布、逆コンパイル、リバース エンジニアリング、逆アセンブルまたは派生物の作成、または（b）モバイル ハンドセットまたは個人用 PC 以外のハードウェア端末への Preview の読み込み、Preview と他のソフトウェアとの結合、または Preview の一部を組み込んだソフトウェアや端末の配布はできません。
+
+3.4 デベロッパーは、Android の断片化につながるような行為をしないことに同意します。これには、Preview から派生したソフトウェア開発キットの配布、作成への参加、宣伝を含みます（ただし必ずしもこれらには限定されません）。
+
+3.5 オープンソース ソフトウェア ライセンス下でライセンス付与された Preview のコンポーネントの使用、複製、配布は、本契約ではなく、そのオープンソース ソフトウェアのライセンスに準拠するものとします。デベロッパーは、許諾されるすべての権利下で、そのようなオープンソース ソフトウェア ライセンスに対して、優良ライセンシーのままでいることに同意し、そのような権利を終了、停止、または違反する可能性のあるいかなる行為も差し控えることに同意するものとします。
+
+3.6 デベロッパーは、Google が提供する Preview の形式および性質は事前の通知なしに変更される場合があり、今後リリースされる Preview のバージョンでは、以前のバージョンの Preview で開発されたアプリケーションとの互換性がない可能性があることに同意します。デベロッパーは、Google が事前の通知なく、Google の単独の裁量でデベロッパーまたはユーザーへの Preview（または Preview 内の一部の機能）の提供を（恒久的または一時的に）停止する場合があることに同意します。
+
+3.7 本契約のいかなる部分も、Google のいかなる商標名、商標、サービスマーク、ロゴ、ドメイン名、またはその他のブランド識別表示を使用する権利もデベロッパーに付与するものではありません。
+
+3.8 デベロッパーは、Preview に添付または収録されているすべての知的財産権に関する通知（著作権および商標の通知を含む）の削除、隠ぺい、改ざんを行わないことに同意します。
+
+4.デベロッパーによる Preview の使用
+
+4.1 Google は、本契約に基づき Preview を使用してデベロッパーが開発したソフトウェア アプリケーションに関して、デベロッパー（またはデベロッパーのライセンサー）からいかなる権利、所有権、または利益（当該アプリケーションに含まれる知的財産権を含む）も取得するものではないことに同意します。
+
+4.2 デベロッパーは、Preview を（a）本契約、および（b）該当する司法管轄区における適用される法律、規則、または一般に認められた慣行またはガイドライン（米国またはその他の該当国におけるデータまたはソフトウェアの輸出入に関する法律を含む）で認められている目的にのみ使用することに同意します。
+
+4.3 Preview を使用してアプリケーションを開発する場合、デベロッパーはユーザーのプライバシーおよび法的権利を保護することに同意します。ユーザーからデベロッパーにユーザー名、パスワード、またはその他のログイン情報または個人情報が提供される場合、デベロッパーは、情報がデベロッパーのアプリケーションに提供されることをユーザーに認識させ、当該ユーザーについてプライバシーに関する法的に十分な通知および保護を行わなければなりません。デベロッパーのアプリケーションに個人情報または秘密情報が保存される場合、この保存は保護された方法で行われなければなりません。ユーザーからデベロッパーのアプリケーションに Google アカウントの情報が提供された場合、デベロッパーのアプリケーションでは、ユーザーが許可したタイミングで、かつユーザーが許可した限定された目的にのみ、当該情報を使用してユーザーの Google アカウントにアクセスすることが認められるものとします。
+
+4.4 デベロッパーは、Preview に関して、第三者（Google、およびあらゆる携帯電話会社を含むが、これらに限定されない）のサーバー、ネットワーク、またはその他の財産またはサービスへの妨害、中断、損害、または許可されていない態様でのアクセスとなる行為（そのような行為に該当する対象製品の開発または販売 / 配布を含む）に関与しないことに同意します。
+
+4.5 デベロッパーは、デベロッパーが Android および Android のアプリケーションを介して作成、送信、表示するデータ、コンテンツ、リソース、および自身の行為の結果（Google に発生する可能性のあるあらゆる損失および損害を含む）について、自身が単独で責任を負うこと（および Google がこれについてデベロッパーまたはいかなる第三者に対しても一切責任を負わないこと）に同意します。
+
+4.6 デベロッパーは、本契約、適用される第三者の契約もしくは利用規約、または適用される法律もしくは規則に基づく自身の義務に違反したこと、および当該違反の結果（Google または第三者に発生したあらゆる損失および損害を含む）について、自身が単独で責任を負うこと（および Google がこれについてデベロッパーまたはいかなる第三者に対しても一切責任を負わないこと）に同意します。
+
+4.7 Preview は開発中であり、デベロッパーによるテスティングやフィードバックは開発プロセスの重要な一部となります。デベロッパーは、Preview の使用により、一部の機能の実装が開発中であると認識し、Preview が安定したリリースの完全な機能性を持つことに依存すべきでないことを認識するものとします。本 Preview は、公式の Android SDK のリリース後はサポート対象でなくなるため、デベロッパーは、Preview を使用するいかなるアプリケーションも公然と配布または引き渡さないことに同意するものとします。
+
+5.デベロッパーの資格情報
+
+5.1 デベロッパーは、Google が発行した、またはデベロッパー自身で選択した、自身のデベロッパー用資格情報の秘密を保持する責任を負うこと、および自身のデベロッパー用資格情報のもとで開発されたすべてのアプリケーションについて単独で責任を負うことに同意します。
+
+6.プライバシーおよび情報
+
+6.1 Google は、Preview の継続的な技術革新と改良のために、ソフトウェアから特定の使用状況統計情報（一意識別子、関連する IP アドレス、ソフトウェアのバージョン番号、Preview のどのツール/サービスがどのように使用されているかに関する情報を含むが、これらに限定されない）を収集できます。この情報が収集される前に、Preview に通知が表示され、デベロッパーの同意が求められます。デベロッパーが同意しない場合は、情報は収集されません。
+
+6.2 収集されるデータは、Preview の改良のために集約された形で精査され、Google のプライバシー ポリシー（http://www.google.com/policies/privacy/）に従って管理されます。
+
+7.第三者のアプリケーション
+
+7.1 デベロッパーが、Preview を使用して第三者が開発したアプリケーションを実行する、あるいは第三者から提供されたデータ、コンテンツ、リソースにアクセスする場合、デベロッパーは、Google がそれらのアプリケーション、データ、コンテンツ、リソースについて責任を負わないことに同意します。デベロッパーは、そのような第三者のアプリケーションを介してアクセスするすべてのデータ、コンテンツ、リソースについては、それらを生成した者が単独で責任を負うものであり、Google はそれらの第三者のアプリケーション、データ、コンテンツ、またはリソースの使用もしくはアクセスによって生じたあらゆる損失および損害について一切責任を負わないことを理解します。
+
+7.2 デベロッパーは、そのような第三者のアプリケーションを介して表示されるデータ、コンテンツ、リソースは、提供者（あるいは代理の第三者または事業体）が所有する知的財産権で保護されている場合があることを認識するものとします。デベロッパーは、当該所有者からの明確な許可がない限り、それらのデータ、コンテンツ、リソース（全体または一部）の変更、貸与、賃貸、担保、配布または派生物の作成を行うことはできません。
+
+7.3 デベロッパーは、そのような第三者のアプリケーション、データ、コンテンツまたはリソースの使用が、デベロッパーと当該第三者間の別の規約に従うものであることを認識するものとします。
+
+8.Google API の使用
+
+8.1 Google API
+
+8.1.1 API を使用して Google からデータを取得する場合、デベロッパーは、そのデータは、Google またはデータを提供する事業体（あるいは代理の第三者または事業体）が所有する知的財産権で保護されている場合があることを認識するものとします。そのような API の使用は追加の利用規約に従うものとします。デベロッパーは、当該の利用規約による許可がない限り、そのデータ（全体または一部）の変更、貸与、賃貸、担保、配布または派生物の作成を行うことはできません。
+
+8.1.2 デベロッパーは、API を使用して Google からユーザーのデータを取得する場合、ユーザーが明示的に同意した場合のみ、およびユーザーが許可したタイミングとその目的にのみ、データを取得できることを理解し、同意します。
+
+9.本契約の終了
+
+9.1 本契約は、下記の規定に従ってデベロッパーまたは Google のいずれかによって解約されるまで、継続して適用されるものとします。
+
+9.2 デベロッパーが本契約の解約を希望する場合は、Preview および関連するデベロッパー資格情報の使用を停止することで、契約を終了するものとします。
+
+9.3 Google は、理由の有無にかかわらず、書面で通知することでいつでもデベロッパーとの本契約を解約することができます。
+
+9.4 本契約は事前の通知またはその他の措置なく、次のうち早い方に自動的に終了します。
+（A）Google が、デベロッパーが居住している国またはデベロッパーがサービスを使用する国での Preview または Preview の一部の配布を停止したとき。
+（B）Google が Android SDK の最終バージョンをリリースしたとき。
+
+9.5 本契約が終了すると、本契約で付与されていたライセンスは終了し、デベロッパーは速やかに Preview のすべての使用を停止するものとし、第 10 条、第 11 条、第 12 条、第 14 条の規定は無期限に効力を有するものとします。
+
+10.免責事項
+
+10.1 デベロッパーは、デベロッパーによる Preview の使用はデベロッパー自身の責任において行うものであること、および Preview は「現状有姿」かつ「提供可能な限りにおいて」、Google からのいかなる種類の保証もなく提供されるものであることを明示的に理解し、これに同意します。
+
+10.2 デベロッパーによる Preview および Preview の使用を通じてダウンロードまたはその他の方法で取得されたマテリアルの使用は、デベロッパー自身の裁量および責任において行うものであり、当該使用の結果として生じるデベロッパーのコンピュータ システムもしくはその他の端末への損害またはデータの喪失についての責任はデベロッパーが単独で負います。前述を制限することなく、Preview は安定したリリースではなく、コンピュータやその他の端末の利用の完全な回復不可能な損失を含む、重大な損害を引き起こす可能性のあるエラー、欠陥、およびセキュリティ上の脆弱性が含まれている可能性があることを理解します。
+
+10.3 Google はまた、商品性、特定目的への適合性、および権利侵害がないことの黙示的な保証および条件を含む（ただしこれらに限定されない）、明示的か黙示的かを問わずあらゆる種類のすべての保証および条件を明示的に否定します。
+
+11.責任の制限
+
+11.1 デベロッパーは、Google、その子会社および関連会社、ならびにそのライセンサーが、デベロッパーに発生した直接損害、間接損害、偶発的損害、特別損害、結果的損害、または懲罰的損害（データの喪失を含む）について、Google またはその代表者が当該損失が発生する可能性について告知されていたかどうか、または知っていたはずであるかどうかにかかわらず、いかなる責任法理のもとでもデベロッパーに対して責任を負わないことを明示的に理解し、これに同意します。
+
+12.補償
+
+12.1 法律で認められる最大限の範囲内において、デベロッパーは、（a）デベロッパーが Preview を使用したこと、および（b）デベロッパーが Preview で開発したアプリケーションが他者のいかなる知的財産権を侵害していること、または他者の名誉を毀損している、もしくは他者のパブリシティ権もしくはプライバシー権を侵害していること、および（c）デベロッパーが本契約に違反したことから発生したあらゆる申し立て、普通法上の訴訟、衡平法上の訴訟、または法的手続き、ならびにあらゆる損失、責任、損害、費用、および経費（合理的な弁護士報酬を含む）について、Google、その関連会社、ならびに当該各社の取締役、役員、従業員、代理人を防御し、補償し、免責することに同意します。
+
+13.契約の変更
+
+13.1 Google は、Preview の新しいバージョンを配布することにより、いつでも本契約を変更することができます。変更が生じた場合、Google は、Preview の提供ウェブサイト上に使用許諾契約の改訂版を公開します。
+
+14.法的一般条項
+
+14.1 本契約は、デベロッパーと Google の間の法的な合意のすべてを表し、デベロッパーによる Preview の使用（別の契約下で Google が提供するサービスを除く）に適用され、Preview に関するデベロッパーと Google の間のあらゆる事前の合意に完全に取って代わるものです。
+
+14.2 デベロッパーは、Google が本契約に定める（または適用される法律のもとで Google が享受できる）法的な権利または救済措置を行使または執行しなかった場合でも、Google の権利が正式に放棄されたとはみなされないこと、および Google が以後も引き続き当該権利および救済措置を行使または執行できることに同意します。
+
+14.3 本件について判断を下す管轄権を有する司法裁判所によって、本契約のいずれかの条項が無効と判断された場合、当該条項は、本契約の残りの部分に影響を与えることなく本契約から削除されるものとします。本契約の残りの条項は、以後も引き続き有効かつ執行可能であるものとします。
+
+14.4 デベロッパーは、Google が親会社となっている各グループ企業が、本契約の第三受益者となること、および当該企業が、当該企業に利益（または受益権）を付与する本契約の条項を直接執行する、また当該条項に依拠する権利を有することを了承し、これに同意します。上記以外のいかなる人または法人も、本契約の第三受益者とはならないものとします。
+
+14.5 輸出規制。Preview は、米国輸出管理法令の対象です。デベロッパーは、Preview に適用されるすべての国内および国際の輸出管理法令に従わなければなりません。これらの法律には、仕向け地、ユーザー、および最終用途に関する制限が含まれます。
+
+14.6 デベロッパーは、Google から事前に書面で承認を得ずに、本契約を譲渡または移転することはできません。また、そのような承認を得ずに計画された譲渡はすべて無効になります。デベロッパーは、Google から事前に書面で承認を得ずに、本契約に基づく自身の責任または義務を他者に委任してはなりません。
+
+14.7 本契約あるいは本契約に基づくデベロッパーと Google の関係から発生または関連するすべての申し立ては、米国カリフォルニア州の抵触法を除いて、カリフォルニア州法に準拠するものとします。デベロッパーおよび Google は、本契約あるいは本契約に基づくデベロッパーと Google の関係から発生または関連する法的事項の解決について、米国カリフォルニア州サンタクララ郡に所在の連邦裁判所または州立裁判所が専属管轄権を有することに合意します。上記にかかわらず、デベロッパーは、Google が任意の司法管轄区において差し止め命令による救済（または同等の緊急法的救済）を求める申し立てを行うことが認められることに同意します。

+이것은 Android SDK 미리 보기 라이선스 계약서입니다(이하 "라이선스 계약").
+
+1. 개요
+
+1.1 Android SDK 미리 보기(본 라이선스 계약에서는 "미리 보기"라고 칭하며, 구체적으로 Android 시스템 파일, 패키지 API 및 미리 보기 라이브러리 파일이 이용 가능한 경우 및 이용 가능하게 전환된 경우 이를 포함한 것을 가리킴)는 본 라이선스 계약 조건에 따라 계약자에게 사용을 허여합니다. 본 라이선스 계약은 미리 보기 사용과 관련하여 계약자와 Google 간에 법적 구속력이 있는 계약을 체결합니다.
+
+1.2 "Android"는 기기를 위한 Android 소프트웨어 스택을 의미합니다. 이는 http://source.android.com/ URL에 위치하며 수시로 업데이트되는 Android 오픈 소스 프로젝트에서 제공됩니다.
+
+1.3 "Google"은 미국 1600 Amphitheatre Parkway, Mountain View, CA 94043에 본사를 두고 있는 델라웨어주 법인인 Google Inc.를 의미합니다.
+
+2. 라이선스 계약에 동의
+
+2.1 이 미리 보기를 사용하려면, 먼저 라이선스 계약에 동의해야 합니다. 이 라이선스 계약에 동의하지 않고 미리 보기를 사용해서는 안 됩니다.
+
+2.2 수락을 클릭하고/거나 미리 보기를 사용하면 본 라이선스 계약 조건에 동의하는 것으로 간주됩니다.
+
+2.3 미국법 또는 현재 거주 중이거나 미리 보기를 사용하는 국가를 포함하여 다른 국가의 법에 따라 미리 보기를 받는 것이 금지된 경우, 미리 보기를 사용할 수 없으며 본 라이선스 계약을 수락할 수 없습니다.
+
+2.4 회사 또는 단체 내에서 내부적으로 미리 보기를 사용하며 고용주 또는 기타 단체를 대신하여 본 라이선스 계약 준수에 동의하는 경우, 계약자의 고용주나 그 단체에 본 라이선스 계약에 대한 구속력을 부여할 수 있는 모든 법적 권한을 계약자가 갖고 있음을 진술하고 보증합니다. 구속력을 부여할 수 있는 법적 권한이 없을 경우, 고용주 또는 기타 단체를 대신하여 본 라이선스 계약에 동의하거나 미리 보기를 사용할 수 없습니다.
+
+3. Google이 허하는 미리 보기 라이선스
+
+3.1 본 라이선스 계약의 조건에 따라 Google은 계약자에게 로열티 없고 양도 불가능하며 비독점적이고 2차 인가를 불허하며, 한정되고 무효화할 수 있는 미리 보기 사용 권한을 허용하여 회사 또는 조직 내에서 개인적 또는 내부적으로 사용할 수 있도록 합니다. 이는 Android 플랫폼에서 실행되는 애플리케이션을 개발할 목적으로만 사용해야 합니다.
+
+3.2 계약자는 SDK에 존재하는 지적 재산권을 포함한 SDK에 대한 모든 법적인 권리, 소유권 및 이익이 Google 또는 제3자에게 있음에 동의합니다 "지적 재산권"은 모든 특허법, 저작권법, 영업비밀법, 상표법상 존재하는 모든 권리 및 기타 모든 재산권을 의미합니다. Google은 계약자에게 명시적으로 부여하지 않은 모든 권리를 보유합니다.
+
+3.3 본 라이선스 계약에 명시적으로 허용된 용도 외에는 미리 보기를 사용할 수 없습니다. 해당 제3자 라이선스 요건이 허용하는 범위를 제외하고 계약자는 미리 보기의 일부분을 (a) 복사(백업 목적 제외), 수정, 개작, 재배포, 역컴파일, 리버스 엔지니어링, 분해하거나 이를 통해 파생물을 생성하거나 (b) 개인 컴퓨터를 제외한 모바일 단말기 또는 기타 모든 하드웨어 기기에 미리 보기의 일부를 로드하거나, 미리 보기의 일부를 다른 소프트웨어와 결합하거나 미리 보기의 일부가 통합된 일체의 소프트웨어나 기기를 배포해서는 안 됩니다.
+
+3.4 계약자는 미리 보기에서 파생된 소프트웨어 개발 키트의 배포, 이러한 키트 생성에 참여 또는 홍보를 포함하되 이에 국한되지 않고, Android의 단편화를 야기하는 어떠한 행동도 취하지 않을 것임에 동의합니다.
+
+3.5 오픈 소스 소프트웨어 라이선스에 의거한 미리 보기 구성요소의 사용, 재생산, 배포에는 본 라이선스 계약이 아닌, 해당 오픈 소스 소프트웨어 라이선스의 조건이 적용됩니다. 계약자는 허용된 모든 권한 하에서 그러한 오픈 소스 소프트웨어 라이선스에 관해 충실한 피허가자로서의 자세를 견지할 것이며 그러한 권한을 종료, 일시 중단 또는 침해하는 행위를 삼갈 것을 동의합니다.
+
+3.6 계약자는 Google이 제공하는 SDK의 형태 및 특성이 사전 통지 없이 변경될 수 있음에 동의하며, 이전 버전의 미리 보기에서 개발된 애플리케이션이 이후 버전의 SDK와 호환되지 않을 수 있음에 동의합니다. 계약자는 계약자 또는 사용자에게 사전 통지 없이 SDK(또는 SDK에 포함된 기능) 제공을(영구적 또는 일시적으로) 중단할 수 있는 권한이 Google에게 있음에 동의합니다.
+
+3.7 본 라이선스 계약은 계약자에게 Google의 상표명, 상표, 서비스 표시, 로고, 도메인 이름, 기타 독특한 브랜드 특징에 대한 사용 권한을 부여하지 않습니다.
+
+3.8 계약자는 SDK에 부착되어 있거나 포함되어 있는 모든 소유권 고지 사항(저작권 및 상표 고지 사항 포함)을 제거, 변경 또는 불분명하게 만들지 않을 것에 동의합니다.
+
+4. 계약자의 미리 보기 사용
+
+4.1 Google은 본 라이선스 계약의 어떤 조항도 계약자(또는 계약자의 사용 허가자)가 미리 보기를 사용하여 개발한 소프트웨어 애플리케이션에 대한 권리, 소유권 또는 이익, 그리고 해당 애플리케이션에 존재하는 모든 지적 재산권을 부여하지 않는다는 점에 동의합니다.

+Este é o contrato de licença do Android SDK Preview (o “Contrato de Licença”).
+
+1. Introdução
+
+1.1 O Android SDK Preview (que este Contrato de licença chama de "Preview", incluindo especificamente os arquivos de sistema do Android, APIs integradas e arquivos da biblioteca Preview, se e quando estiverem disponíveis) é licenciado por meio da concordância com os termos deste contrato. O Contrato de licença forma um vínculo contratual legal entre o contratante e a Google em relação ao uso do Preview.
+
+1.2 "Android" se refere à pilha de software do Android para dispositivos, conforme disponibilizado no Projeto de código aberto do Android, localizado no URL a seguir: http://source.android.com/, atualizado periodicamente.
+
+1.3 "Google" refere-se à Google Inc, uma corporação de Delaware, com sede em 1600 Amphitheatre Parkway, Mountain View, CA 94043, Estados Unidos.
+
+2. Aceitação do Contrato de Licença
+
+2.1 A fim de usar o Preview, é necessário concordar com este Contrato de licença. O uso do Preview é proibido àqueles que não concordam com este Contrato de licença.
+
+2.2 Ao clicar em aceitar e/ou usar o Preview, você concorda com os termos do Contrato de licença
+
+2.3 É proibido o uso do Preview e a aceitação deste contrato pelo indivíduo que tenha impedimento legal sobre o recebimento do Preview sob as leis dos Estados Unidos ou de outros países, incluindo o país de residência ou no qual usa o Preview.
+
+2.4 Se for usar o Preview internamente na empresa ou organização, você deverá concordar com o vínculo com este contrato em nome do empregador ou de outra entidade e declarar e garantir que tem total autoridade legal para tanto. Se você não tem a autoridade necessária, não deve concordar com este contrato nem usar o Preview em nome do empregador ou de outra entidade.
+
+3. Licença do Preview da Google
+
+3.1 Sujeito aos termos do Contrato de licença, a Google confere uma licença limitada, revogável, livre de taxas, intransmissível, não sub-licenciável e não exclusiva para o uso apenas do Preview, pessoal ou internamente dentro da sua empresa ou organização, para fins de desenvolvimento de aplicativos executados na plataforma do Android.
+
+3.2 Você concorda que a Google ou terceiros detêm todos os direitos legais, títulos e interesses relativos ao Preview, incluindo quaisquer direitos de propriedade intelectual que subsistam no Preview. "Direitos de propriedade intelectual" se referem a todo e qualquer direito sob as leis de patentes, de direitos autorais, de segredo comercial, de marca registrada e todos os outros direitos de propriedade. A Google reserva todos os direitos não conferidos expressamente a você.
+
+3.3 O uso do Preview não é autorizado para qualquer finalidade não expressamente permitida por este Contrato de licença. Salvo na extensão exigida por licenças aplicáveis de terceiros, é proibido: (a) copiar (exceto para fins de cópia de segurança), modificar, adaptar, redistribuir, descompilar, fazer engenharia reversa, desmontar ou criar trabalhos derivados do Preview ou qualquer parte dele; ou (b) carregar qualquer parte do Preview em um aparelho celular ou outro dispositivo de hardware, exceto em computador pessoal, combinar qualquer parte do Preview com outros softwares ou distribuir qualquer software ou dispositivo que contenha uma parte do Preview.
+
+3.4 Você concorda que não tomará quaisquer medidas que possam causar ou resultar em fragmentação do Android, incluindo, sem limitar-se, a distribuição e a participação na criação ou na promoção, sob quaisquer formas, de um conjunto de desenvolvimento de software derivado do Preview.
+
+3.5 O uso, a reprodução e a distribuição de componentes do Preview licenciado sob licença de software de código aberto são regidos exclusivamente pelos termos daquela licença de software de código aberto, e não por este Contrato de licença. Você concorda em manter uma licença em bom estado para as licenças de software de código aberto sob todos os direitos concedidos e deter quaisquer ações que possam limitar, suspender ou romper tais direitos.
+
+3.6 Você concorda que a forma e a natureza do SDK que a Google fornece podem mudar sem aviso prévio e que as versões futuras do SDK podem ser incompatíveis com aplicativos desenvolvidos em versões anteriores do SDK. Você concorda que a Google pode cessar (permanente ou temporariamente) o fornecimento do Preview (ou quaisquer recursos dentro dele) a você ou a usuários em geral sob critério exclusivo da Google, sem aviso prévio.
+
+3.7 Nada neste Contrato de licença confere o direito de uso de quaisquer nomes comerciais, marcas comerciais, marcas de serviço, logomarcas, nomes de domínios e outros recursos de marcas especiais da Google.
+
+3.8 Você concorda que não removerá, ocultará nem alterará quaisquer observações de direitos de propriedade (incluindo observações de direitos autorais e de marcas registradas) que possam estar afixadas ou contidas no Preview.
+
+4. Uso do Preview por você
+
+4.1 A Google compreende que nada no Contrato de licença dá a ela direito, título nem interesse no usuário (ou em seus licenciadores), sob o presente Contrato de licença, no que tange ao desenvolvimento de aplicativos de software através do uso do Preview, incluindo quaisquer direitos de propriedade intelectual que subsistam nos referidos aplicativos.
+
+4.2 Você concorda em usar o Preview e desenvolver aplicativos somente para as finalidades permitidas por (a) este Contrato de licença e (b) quaisquer leis, normas, diretrizes geralmente aceitas ou orientações aplicáveis nas jurisdições relevantes (incluindo quaisquer leis acerca da exportação e da importação de dados ou softwares nos Estados Unidos ou em outros países relevantes).
+
+4.3 Você concorda que, se usar o Preview para o desenvolvimento de aplicativos, deverá proteger a privacidade e os direitos legais destes usuários. Se nomes de usuário, senhas ou outras informações de acesso ou informações pessoais forem fornecidos ao aplicativo, deve-se informá-los de que tais dados estarão disponíveis para o aplicativo, além de fornecer observações de privacidade e proteção legalmente adequadas a esses usuários. Se o aplicativo armazenar informações pessoais ou confidenciais fornecidas pelos usuários, deve fazê-lo com segurança. Se o usuário fornecer informações da conta do Google, o aplicativo poderá usar essas informações exclusivamente para acessar a conta da Google do usuário quando houver autorização para fazê-lo e para os fins limitados pela autorização.
+
+4.4 Você concorda que não se envolverá em qualquer atividade com o Preview, incluindo o desenvolvimento e a distribuição de um aplicativo que interfira, perturbe, danifique ou acesse, de modo não autorizado, servidores, redes ou outras propriedades ou serviços da Google ou qualquer outro terceiro.
+
+4.5 Você concorda que é exclusivamente responsável por (e que a Google não tem qualquer responsabilidade com você ou terceiro) quaisquer dados, conteúdo ou recursos que criar, transmitir ou exibir por meio do Android e/ou de aplicativos do Android e pelas consequências que suas ações (incluindo perda ou dano que a Google possa sofrer) podem gerar.
+
+4.6 Você concorda que é exclusivamente responsável por (e que a Google não tem qualquer responsabilidade com você ou terceiro) qualquer violação das obrigações exigidas neste Contrato de licença, qualquer contrato ou termos de serviço aplicáveis a terceiros, qualquer lei ou norma aplicável e pelas consequências (incluindo a perda ou dano que a Google ou qualquer terceiro possa sofrer) de quaisquer violações.
+
+4.7 O Preview está em desenvolvimento e o seu teste e feedback são uma parte importante deste processo. Ao usar o Preview, você está ciente de que a implementação de alguns recursos ainda estão em desenvolvimento e que não se deve confiar que o Preview tem a funcionalidade completa de uma versão estável. Você concorda em não distribuir nem enviar publicamente quaisquer aplicativos usando este Preview, pois ele não será mais suportado após o lançamento oficial do Android SDK.
+
+5. Suas credenciais de desenvolvedor
+
+5.1 Você é responsável pela manutenção da confidencialidade de quaisquer credenciais de desenvolvedor que possam ser emitidas pela Google ou escolhidas por você e será o único responsável por todos os aplicativos que forem desenvolvidos sob suas credenciais de desenvolvedor.
+
+6. Privacidade e informações
+
+6.1 A fim de inovar e aprimorar continuamente o Preview, a Google pode coletar certas estatísticas de uso do software, incluindo, sem limitar-se, um identificador exclusivo, endereço IP associado, número de versão do software e informações sobre quais ferramentas e/ou serviços no Preview estão sendo usados e como estão sendo usados. Antes de coletar quaisquer dessas informações, o Preview o notificará e buscará seu consentimento. Se você recusar, as informações não serão coletadas.
+
+6.2 Os dados coletados são examinados coletivamente para aprimorar o Preview e são mantidos em conformidade com a Política de privacidade da Google acessível em http://www.google.com/policies/privacy/.
+
+7. Aplicativos de terceiros
+
+7.1 Ao usar o Preview para executar aplicativos desenvolvidos por terceiros ou que acessam dados, conteúdo ou recursos fornecidos por terceiros, você concorda que a Google não é responsável por tais aplicativos, dados, conteúdo ou recursos. Você compreende que quaisquer dados, conteúdo ou recursos passíveis de aceitação por meio de tais aplicativos de terceiros imputam responsabilidade exclusiva ao indivíduo que os originou. A Google não é responsável por qualquer perda ou dano que possa ocorrer como resultado do uso ou acesso de quaisquer aplicativos, dados, conteúdo ou recursos de terceiros.
+
+7.2 Você deve estar ciente de que os dados, conteúdo e recursos apresentados a você por aplicativos de terceiros podem ser protegidos pelos direitos de propriedade intelectual de posse dos fornecedores (ou de outras pessoas ou empresas em seus nomes). Não é permitido modificar, alugar, arrendar, emprestar, vender, distribuir nem criar trabalhos derivados com base nestes dados, conteúdo ou recursos (na totalidade ou em parte), salvo se houver permissão explícita especificada pelos respectivos detentores de direitos.
+
+7.3 Você reconhece que o uso de tais aplicativos, dados, conteúdo ou recursos de terceiros pode estar sujeito a termos adicionais entre você e o terceiro em questão.
+
+8. Uso de APIs da Google
+
+8.1 APIs da Google
+
+8.1.1 Ao usar qualquer API para recuperar dados da Google, você reconhece que eles podem ser protegidos por direitos de propriedade intelectual de posse da Google ou dos terceiros que fornecem os dados (ou de pessoas ou empresas em nomes deles). O uso de tal API pode estar sujeito a termos de serviço adicionais. Não é permitido modificar, alugar, arrendar, emprestar, vender, distribuir nem criar trabalhos derivados baseados nesses dados (na totalidade ou em parte), salvo se permitido pelos termos de serviço pertinentes.
+
+8.1.2 Se você usar qualquer API para recuperar dados de um usuário a partir da Google, reconhece e concorda que deve recuperar dados somente com consentimento explícito do usuário e somente quando, e para os fins limitados aos quais, o usuário conceder permissão para fazê-lo.
+

+
+9.1 O Contrato de licença continuará a se aplicar até que ocorra uma rescisão sua ou da Google, como definido abaixo.
+
+9.2 Caso queira rescindir o Contrato de licença, você pode fazer isto cessando o uso do Preview e de qualquer credencial de desenvolvedor relevante.
+
+9.3 A Google pode, a qualquer momento, rescindir o Contrato de licença, com ou sem causa, com uma notificação.
+
+9.4 O Contrato de licença será encerrado automaticamente sem aviso ou outras ações na ocorrência de:
+(A) a Google interromper o fornecimento do Preview ou de determinadas partes do Preview aos usuários no país em que você reside ou de onde o serviço é usado; e
+(B) a Google emitir uma versão de lançamento final do Android SDK.
+
+9.5 Quando o Contrato de licença é rescindido, a licença concedida a você no Contrato de licença é finalizada, todo o uso do Preview será interrompido e as provisões dos parágrafos 10, 11, 12 e 14 deverão permanecer indefinidamente.
+

Não obstante a isso, você concorda que a Google continua habilitada a impetrar medidas cautelares (ou mecanismo legal urgente equivalente) em qualquer jurisdição.

+
+    <div class="sdk-terms" onfocus="this.blur()" style="width:678px">
+Это лицензионное соглашение для пакета SDK Android Preview (далее «Лицензионное соглашение»).
+
+1. Введение
+
+1.1. Лицензия на пакет SDK Android Preview (далее по тексту настоящего Лицензионного соглашения – «Preview», который включает системные файлы Android, пакеты API-интерфейсов и файлы библиотеки Preview, если такие доступны) передается в соответствии с положениями настоящего Лицензионного соглашения. Настоящее Лицензионное соглашение является юридически обязывающим договором между компанией Google и любым лицом, использующим Preview.
+
+1.2. В настоящем Лицензионном соглашении термин «Android» означает набор программного обеспечения Android для устройств, предлагаемый к использованию в рамках проекта Android Open Source Project, который доступен на веб-сайте http://source.android.com/ (сведения, размещенные на этом сайте, могут периодически обновляться).
+
+1.3. Под термином «Google» понимается корпорация Google Inc., главный офис которой находится по адресу 1600 Amphitheatre Parkway, Mountain View, CA 94043, United States (США).
+
+2. Принятие лицензионного соглашения
+
+2.1. Использование Preview возможно только после принятия условий настоящего Лицензионного соглашения. Запрещается использовать Preview, если вы не согласны с указанными в настоящем документе условиями и положениями.
+
+2.2. Нажатие кнопки принятия условий и/или использование Preview означает, что вы согласны с положениями настоящего Лицензионного соглашения.
+
+2.3. Вы не вправе использовать Preview и принимать условия данного Лицензионного соглашения, если по законам США или иных стран, включая страну вашего проживания или использования Preview, запрещается передавать Preview в ваш адрес.
+
+2.4. Если вы используете Preview в рамках своей компании или организации, вы соглашаетесь взять на себя обязательства по соблюдению настоящего Лицензионного соглашения от имени своего работодателя или другого юридического лица, и вы тем самым подтверждаете и гарантируете, что обладаете полными юридическими полномочиями связать вашего работодателя или иное подобное юридическое лицо обязательствами по настоящему Лицензионному соглашению. Если вы не обладаете необходимыми полномочиями, вы не вправе принимать указанные в настоящем документе условия и положения или использовать Preview от имени вашего работодателя или другого юридического лица.
+
+3. Лицензия на Preview от Google
+
+3.1. В соответствии с условиями настоящего Лицензионного соглашения Google предоставляет вам ограниченную, бесплатную и неэксклюзивную лицензию без права передачи и подлежащую отмене, на использование Preview, лично или в рамках своей компании или организации, исключительно в целях разработки приложений для платформы Android.
+
+3.2. Вы соглашаетесь с тем, что Google или третьим сторонам принадлежат все юридические и имущественные права, а также правовой интерес в отношении Preview, в том числе любые права на объекты интеллектуальной собственности, которые имеются в Preview. Термин «Права на интеллектуальную собственность» означает все возможные права в рамках патентного права, авторского права, закона о коммерческой тайне, закона о товарных знаках, а также иные возможные имущественные права. Google оставляет за собой все права, не предоставленные вам в явном виде.
+
+3.3. Вам запрещается использовать Preview в любых целях, которые однозначно не определены в настоящем Лицензионном соглашении. За исключением случаев, предусмотренных применимыми сторонними лицензиями, вам запрещается: (a) копировать (кроме случаев резервного копирования), изменять, адаптировать, повторно распространять, декомпилировать, осуществлять инженерный анализ, деассемблировать или создавать производные элементы Preview или иной его части; а также (b) загружать любую часть Preview в мобильные телефоны или иные устройства, помимо персонального компьютера, объединять любые части Preview с другим программным обеспечением, распространять любое программное обеспечение или устройства, содержащие части Preview.
+
+3.4. Вы соглашаетесь с тем, что не будете предпринимать никаких действий, которые прямо или косвенно могут привести к фрагментированию платформы Android, включая помимо прочего распространение набора средств разработки программного обеспечения, полученного из Preview, участие в создании таких средств и содействие их продвижению в любой форме.
+
+3.5. Использование, воспроизведение и распространение компонентов Preview, на которые распространяется лицензия на программное обеспечение с открытым исходным кодом, регулируются исключительно положениями и условиями такой лицензии на программное обеспечение с открытым исходным кодом, а не настоящим Лицензионным соглашением. Вы соглашаетесь обеспечивать хорошую репутацию получателя лицензии в отношении таких лицензии на программное обеспечение с открытым исходным кодом в рамках всех предоставленных ему прав, а также не допускать каких-либо действий, которые могут привести к аннулированию, приостановлению или нарушению таких прав
+
+3.6. Вы соглашаетесь с тем, что форма и содержание Preview , предоставляемого Google, могут быть изменены без предварительного уведомления, а также с тем, что будущие версии Preview могут оказаться несовместимыми с приложениями, разработанными в предыдущих версиях Preview. Вы соглашаетесь с тем, что Google вправе по собственному усмотрению и без предварительного уведомления прекратить (временно или навсегда) предоставление Preview (или любых функций в составе Preview) вам или пользователям.
+
+3.7. Ни одна из частей настоящего Лицензионного соглашения не предусматривает предоставления вам права использовать любые торговые наименования, товарные знаки, знаки обслуживания, логотипы, имена доменов или иные отличительные фирменные знаки, принадлежащие Google.
+
+3.8. Вы соглашаетесь с тем, что обязуетесь не удалять, не скрывать или не изменять любые уведомления об имущественных правах (включая уведомления об авторских правах и товарных знаках), которые могут сопровождать Preview или содержаться в нем.
+
+4. Использование Preview
+
+4.1. Компания Google выражает согласие с тем, что ни по какому положению настоящего Лицензионного соглашения не получает от вас (или ваших лицензиаров) каких-либо юридических и имущественных прав, а также правового интереса в отношении любых программных приложений, разработанных вами с помощью Preview, включая любые права на объекты интеллектуальной собственности, которые имеются в таких приложениях.
+
+4.2. Вы соглашаетесь использовать Preview и создавать приложения исключительно в целях, предусмотренных (a) настоящим Лицензионным соглашением и (b) любым применимым законом, нормативным актом или общепринятыми правилами или рекомендациями в соответствующей юрисдикции (включая любые законы, касающиеся экспорта данных или программного обеспечения из США или иных соответствующих стран, а также импорта в них).
+
+4.3. Вы соглашаетесь с тем, что при использовании Preview для разработки приложений вы обязуетесь обеспечивать конфиденциальность и защищать юридические права пользователей. В случае, если пользователи предоставляют вам свои имена, пароли или иные данные для входа либо свои персональные данные, вы обязуетесь уведомить пользователей о том, что такая информация будет присутствовать в вашем приложении, и вы также обязуетесь предоставить пользователям юридически соответствующие уведомление о конфиденциальности и средства правовой защиты. Если в вашем приложении хранится личная или конфиденциальная информация, предоставленная пользователями, вы обязуетесь обеспечить ее надлежащую защиту. Если пользователь предоставляет вам сведения о своей учетной записи Google, то ваше приложение может использовать такую информацию для доступа к учетной записи Google пользователя только при условии, что пользователь предоставил вам разрешение на это, и только в тех целях, которые обозначил пользователь.
+
+4.4. Вы соглашаетесь с тем, что обязуетесь не использовать Preview для любого рода деятельности, в том числе для разработки или распространения приложений, в целях нарушения работы и повреждения серверов, сетей или иной собственности или служб Google или любой третьей стороны.
+
+4.5. Вы соглашаетесь с тем, что несете единоличную ответственность (и признаете, что компания Google не несет ответственности ни перед вами, ни перед любой третьей стороной) за любые данные, содержимое или ресурсы, которые вы создаете, передаете или демонстрируете посредством Android и/или приложений для Android, а также за любые последствия ваших действий, связанных с этим (в том числе за любые убытки и любой ущерб, которые могут быть причинены Google).
+
+4.6. Вы соглашаетесь с тем, что несете единоличную ответственность (и признаете, что компания Google не несет ответственности ни перед вами, ни перед любой третьей стороной) за любое несоблюдение обязательств по настоящему Лицензионному соглашению, обязательств по любому применимому договору с третьей стороной или предусмотренных Условиями и положениями, за нарушение любых применимых законов или нормативных актов, а также за любые последствия ваших действий, связанных с таким нарушением (в том числе за любые убытки и любой ущерб, которые могут быть причинены Google).
+
+4.7 Preview находится на стадии разработки, поэтому ваши отзывы и результаты тестирования являются важной частью процесса разработки. Используя Preview, вы признаете, что реализация некоторых функций по-прежнему находится на этапе разработки и вам не следует рассчитывать на полную функциональность стабильной версии. Вы соглашаетесь не распространять или предоставлять любые приложения, использующие Preview, поскольку поддержка Preview будет прекращена после выпуска официальной версии пакета SDK Android.
+
+5. Ваши учетные данные разработчика
+
+5.1. Вы соглашаетесь с тем, что несете ответственность за обеспечение конфиденциальности любых учетных данных разработчика, которые компания Google может вам предоставить или которые вы можете самостоятельно выбрать, а также с тем, что вы несете единоличную ответственность за все приложения, разработанные с использованием ваших учетных данных разработчика.
+
+6. Конфиденциальность и личная информация
+
+6.1. В целях постоянного совершенствования и улучшения Preview компания Google вправе собирать определенные статистические данные об использовании программного обеспечения, включая уникальный идентификатор, связанный IP-адрес, номер версии программного обеспечения, а также сведения об используемых в Preview инструментах и/или службах и способах их применения. Перед тем как любые из таких данных будут отправлены в Google, в Preview отобразится соответствующее уведомление с просьбой дать свое согласие. В случае вашего отказа предоставить такие сведения соответствующие данные собираться не будут.

+
+2.1 要使用“预览版”，您必须先同意本许可协议。如果您不接受本许可协议，则不得使用“预览版”。
+
+2.2 点击接受并/或使用“预览版”，即表示您特此同意本许可协议的条款。
+
+2.3 如果依照美国或其他国家/地区（包括您居住或您使用“预览版”所在的国家/地区）的法律，您被禁止获取“预览版”，则您不得使用“预览版”，也不得接受本许可协议。
+
+2.4 如果您将在贵公司或组织内部使用“预览版”，则您同意代表您的雇主或其他实体接受本许可协议的约束，并且您表示并保证您拥有完全的合法授权令您的雇主或上述实体受本许可协议的约束。如果您不具备必要的授权，则不得代表您的雇主或其他实体接受本许可协议或使用“预览版”。
+
+3. Google 预览版许可

+3.1 Google 依据本许可协议的条款授予您个人或在贵公司或组织内部有限使用“预览版”的免版税、不可转让、非独占性、不可再授权且可撤销的许可，其用途仅限开发在 Android 平台上运行的应用。
+
+3.2 您同意 Google 或第三方拥有“预览版”中存在或相关的全部合法权利、所有权和利益，包括“预览版”中存在的任何知识产权。“知识产权”是指根据专利法、版权法、商业机密法、商标法享有的任何及全部权利，以及其他任何及全部专有权利。Google 保留所有未明确授予您的权利。
+
+3.3 您不得将“预览版”用于本许可协议未明确允许的任何用途。您不得：(a) 对“预览版”或“预览版”的任何部分进行复制（备份用途除外）、修改、改编、再分发、反编译、逆向工程、反汇编或创建其衍生品；或 (b) 将“预览版”的任何部分加载到移动手持终端或除个人计算机之外的任何其他硬件设备上，将“预览版”的任何部分与其他软件合并，或者发行任何融入“预览版”某一部分的软件或设备。
+
+3.4 您同意您将不会进行任何可能引起或导致 Android 碎片化的行动，包括但不限于分发、参与创建或以任何方式推广从“预览版”衍生的软件开发工具包。
+
+3.5 对于依据开源软件许可授权的“预览版”组件，其使用、复制和分发仅受该开源软件许可条款的制约，不受本许可协议的约束。您同意在依照被授予的所有权利作为被许可方期间，在遵守此类开源软件许可协议方面始终保持良好的信誉，并避免进行任何可能导致终止、暂停或违反此类权利的行动。
+
+3.6 您同意 Google 所提供“预览版”的形式和性质可随时发生变更，而无需事先通知您，并且未来的“预览版”版本可能会与在之前的“预览版”版本上开发的应用不兼容。您同意 Google 可单方面决定在未事先通知您的情况下全面停止（永久性或暂时性）向您或用户提供“预览版”（或“预览版”内的任何功能）。
+
+3.7 本许可协议内没有任何条款授予您使用 Google 的任何商品名、商标、服务标志、徽标、域名或其他独特品牌特征的权利。
+
+3.8 您同意您不会移除、遮盖或篡改“预览版”上可能贴有或“预览版”内可能包含的任何专有权利声明（包括版权声明和商标声明）。
+
+4. 您对“预览版”的使用
+
+4.1 Google 同意本许可协议中的任何条款均未授予 Google 从您（或您的许可方）处获取您依照本许可协议使用“预览版”开发的任何软件应用中存在或与其相关的权利、所有权或利益，包括这些应用中存在的任何知识产权。
+
+4.2 您同意只出于 (a) 本许可协议和 (b) 相关管辖区域内任何适用法律、法规或公认惯例或准则（包括有关向美国或其他相关国家/地区出口数据或软件或从美国或其他相关国家/地区进口数据或软件的任何法律）所允许的目的而使用“预览版”和编写应用。
+
+4.3 您同意，如果您使用“预览版”开发应用，您将会保护用户的隐私权和合法权利。如果用户向您提供用户名、密码或其他登录信息或个人信息，您必须确保用户知晓这些信息将供您的应用使用，并且您必须为这些用户提供足以满足法律要求的隐私声明和保护。如果您的应用存储由用户提供的个人信息或敏感信息，其存储方式必须安全。如果用户向您提供 Google 帐户信息，您的应用只能在用户允许时出于用户所许可的有限目的使用该信息访问用户的 Google 帐户。
+
+4.4 您同意您不会利用“预览版”从事任何干扰、中断、损坏或以未经授权方式访问 Google 或任何第三方的服务器、网络或其他财产或服务的Activity（包括应用的开发或分发）。
+
+4.5 您同意您对通过 Android 和/或 Android 应用创建、传输或显示的任何数据、内容或资源以及您的行为所导致的后果（包括 Google 可能遭受的任何损失或损害）负全责（Google 在上述方面对您或任何第三方不承担任何责任）。
+
+4.6 您同意您为违反本许可协议、任何适用的第三方合约或服务条款或任何适用法律或法规下的义务以及任何上述违规行为所导致的后果（包括 Google 或任何第三方可能遭受的任何损失或损害）负全责（Google 在上述方面对您或任何第三方不承担任何责任）。
+
+4.7 “预览版”正在开发中，您的测试和反馈是开发过程的重要环节。使用“预览版”，即表示您承认某些功能仍在开发实现之中，您不应期望“预览版”具备稳定版本的全部功能。您同意不使用此“预览版”公开发布或发运任何应用，因为此“预览版”在 Android SDK 正式发行之后将不再受支持。
+
+5. 您的开发者凭据
+
+5.1 您同意，对于 Google 可能向您发放或可能由您自行选择的任何开发者凭据，您有责任保持其机密性，并且您对以您的开发者凭据名义开发的所有应用负全责。
+
+6. 隐私权和信息
+
+6.1 为持续创新和改进“预览版”，Google 可能会从软件收集某些使用统计数据，包括但不限于唯一标识符、关联的 IP 地址、软件的版本号以及有关软件使用了“预览版”中哪些工具和/或服务及其使用方式的信息。在收集任何上述信息之前，“预览版”都会通知您并征求您的同意。如果您拒绝同意，我们将不会收集这些信息。
+
+6.2 我们会对收集的数据进行汇总调查，以便改进“预览版”，并会按照 Google 的隐私政策（网址为 http://www.google.com/policies/privacy/）维护数据。
+
+7. 第三方应用
+
+7.1 如果您使用“预览版”运行由第三方开发或访问由第三方提供的数据、内容或资源的应用，您同意 Google 对这些应用、数据、内容或资源不承担任何责任。您理解，您通过上述第三方应用可能访问到的所有数据、内容或资源由其提供者负全责，Google 对您因使用或访问其中任何第三方应用、数据、内容或资源而遭受的任何损失或损害不承担任何责任。
+
+7.2 您应知晓，通过此类第三方应用提供给您的数据、内容和资源可能受提供商（或代表他们的其他人员或公司）所拥有的知识产权的保护。除非相关所有者明确给予许可，否则您不得修改、出租、租赁、借出、出售、分发这些数据、内容或资源（的全部或部分），或以其为基础创建衍生品。
+
+7.3 您承认您对上述第三方应用、数据、内容或资源的使用可能受到您与相关第三方之间单独订立的条款的制约。
+
+8. 使用 Google API
+
+8.1 Google API
+
+8.1.1 如果您使用任何 API 从 Google 检索数据，即表示您承认这些数据可能受到 Google 或这些数据提供方（或代表他们的其他人员或公司）拥有的知识产权的保护。您对任何上述 API 的使用可能受到附加服务条款的制约。除非相关服务条款允许，否则您不得修改、出租、租赁、借出、出售、分发这些数据（的全部或部分），或以其为基础创建衍生品。
+
+8.1.2 如果您使用任何 API 从 Google 检索用户数据，即表示您承认并同意您只有在征得用户明确同意时才会检索数据，并且只能在用户允许时出于用户许可的有限目的检索数据。
+

+(A) Google 在您居住或使用服务所在国家/地区停止向用户提供“预览版”或“预览版”的某些部分；
+(B) Google 发行 Android SDK 的最终版本。
+
+9.5 在本许可协议终止时，本许可协议中向您授予的许可将终止，您应立即完全停止使用“预览版”，并且第 10、11、12 和 14 节的条款将无限期继续存在。
+
+10. 免责声明
+
+10.1 您明确理解并同意，您使用“预览版”的风险将由您自行承担，并且“预览版”是按“原样”和“现状”提供，Google 不提供任何类型的担保。
+
+10.2 您对“预览版”的使用以及通过使用“预览版”下载或以其他方式获得的任何材料由您自行决定，风险自负，并且对于因此类使用而对您的计算机系统或其他设备造成的任何损害或数据损失由您单方面负责。在不对上文所述予以限制的条件下，您了解“预览版”并非稳定版本，可能存在将导致重大损害的错误、缺陷和安全漏洞，包括无法挽回地完全无法使用您的计算机系统或其他设备。
+
+10.3 Google 进一步明确拒绝任何类型的所有担保和条件，无论明示或暗示，包括但不限于有关适销性、特定用途适用性以及非侵权的暗示担保和条件。
+
+11. 有限责任
+
+11.1 您明确理解并同意，对于您可能遭遇的任何直接、间接、附带、特殊、继发或惩罚性损害（包括任何数据损失），Google 及其子公司和附属公司以及其许可方在任何责任理论下对您概不承担任何责任，无论 Google 或其代表是否已被告知或是否本应知晓发生任何上述损失的可能性。
+
+12. 赔偿
+
+12.1 您同意，在法律所允许的最大限度内，为 Google、其附属公司及其各自的董事、高管、员工和代理商提供辩护，使其免于因下列情况引起或产生的任何及所有索赔、诉讼、起诉或诉讼程序以及任何及所有损失、债务、损害、成本和费用（包括合理的律师费用）而承担责任或遭受损害：(a) 您对“预览版”的使用；(b) 您在“预览版”上开发的任何应用侵犯任何人的任何知识产权或诽谤任何人或侵犯其公开权或隐私权；以及 (c) 您的任何行为有悖于本许可协议

+13.1 Google 可能会在分发新版本“预览版”时对许可协议做出更改。做出这些更改后，Google 将在提供“预览版”的网站上公布新版本的许可协议。
+
+14. 一般法律条款
+
+14.1 本许可协议构成您与 Google 之间的完整法律协议，管辖您对“预览版”（不包括 Google 可能依据另外的书面协议向您提供的任何服务）的使用，并完全取代您之前与 Google 之间签订的、与“预览版”有关的任何协议。
+
+14.2 您同意，如果 Google 未行使或未强制执行本许可协议包含的任何法定权利或救济（或 Google 在任何适用法律下享有的相关利益），不得视为 Google 正式放弃这些权利，Google 仍可获得这些权利或救济。
+
+14.3 如果任何拥有管辖权的法院将本许可协议的任何条款裁定为无效，则该条款将从本许可协议中删除，而不会影响本许可协议的其余部分。本许可协议的其余条款将继续有效且可强制执行。
+
+14.4 您承认并同意，Google 集团旗下的每一家公司都将成为本许可协议的第三方受益人，并且此类其他公司将有权直接强制执行和依赖本许可协议中任何授予其利益（或支持其权利）的条款。除此之外，任何其他人员或公司均不得成为本许可协议的第三方受益人。
+
+14.5 出口限制。“预览版”受美国出口法律和法规的制约。您必须遵守适用于“预览版”的所有国内和国际出口法律和法规。这些法律包括目的地、最终用户和最终用途方面的限制。
+
+14.6 未经 Google 事先书面批准，您不得擅自转让或转移本许可协议，未经此类批准而试图进行的任何转让均为无效。未经 Google 事先书面批准，您不得委托您依据本许可协议所应承担的责任或义务。

+2.4 如果您將在公司或組織內部使用「預覽版」，您就要代表雇主或其他實體同意受「授權協議」約束，且您代表並保證具備完整法定權限來約束您的雇主或這類實體遵守「授權協議」。如果您不具備必要的權限，就不得代表您的雇主或其他實體接受「授權協議」或使用此「預覽版」。
+
+3.Google 的預覽版授權
+
+3.1 在「授權協議」之條款的約束下，Google 授權您使用此「預覽版」，此授權為買斷式、不可轉讓、非獨占性、不可轉授權、有限且可撤銷，僅在您公司或組織內部私下或內部使用。此「預覽版」僅供您用於開發在 Android 平台上執行的應用程式。
+
+3.2 您同意 Google 或第三方對此「預覽版」擁有一切法定權利及權益，包括存在於此「預覽版」中的任何「智慧財產權」。「智慧財產權」係指專利法、著作權法、商業秘密法、商標法及任何和所有其他專利權下的任何及一切權利。Google 保留一切未明確授予您的權利。
+
+3.3 您不得將此「預覽版」用於「授權協議」未明文許可的任何用途。除非適用的第三方授權所需，否則您不得：(a) 對此「預覽版」或其任何部分進行複製 (備份用途除外)、修改、改編、轉散佈、反向組譯、還原工程、解編或製作衍生成品；或是 (b) 將此「預覽版」的任何部分載入至行動電話或個人電腦以外的任何其他硬體裝置、將此「預覽版」的任何部分與其他軟體結合，或散佈包含此「預覽版」之任一部分的任何軟體或裝置。
+
+3.4 您同意不會從事任何可能導致或造成 Android 分裂的活動，包括但不限於以任何形式散佈從此「預覽版」衍生的軟體開發套件、參其製作或宣傳。
+
+3.5 對開放原始碼軟體授權下所授權之「預覽版」的使用、複製及散佈，完全受該開放原始碼軟體授權的條款管制，而不受「授權協議」管制。您同意遵守從這類開放原始碼軟體授權獲得的所有權利，並且避免採取任何可能終止、中止或侵害這類權利的行為。
+
+3.6 您同意 Google 可在不事先通知您的情況下變更其所提供之「預覽版」的形式和本質，且此「預覽版」的未來版本可與在此「預覽版」的先前版本上開發的應用程式不相容。您同意 Google 通常可全權斟酌永久或暫時停止提供此「預覽版」(或此「預覽版」的任何功能) 給您或使用者，毋須事先通知。
+
+3.7「授權協議」中的所有條款皆未授予您任何使用 Google 之商業名稱、商標、服務標章、標誌、網域名稱或其他明確品牌特徵的權利。
+
+3.8 您同意不會移除、遮蔽或更改可能附加至或內含在此「預覽版」中的任何專利權通知 (包括著作權和商標通知)。
+
+4.您對「預覽版」的使用
+
+4.1 Google 同意在「授權協議」下，任何條款皆未從您 (或您的授權人) 賦予 Google 對您使用此「預覽版」開發之任何軟體應用程式的任何權利及權益，包括存在於這些應用程式中的任何智慧財產權。
+
+4.2 您同意只就 (a)「授權協議」和 (b) 相關管轄權中任何適用法律、規定或是普遍獲得接受之慣例或指導方針 (包括任何有關將資料或軟體輸出或輸入美國或其他相關國家/地區的法律) 所允許的用途使用此「預覽版」及撰寫應用程式。
+
+4.3 您同意如果使用此「預覽版」開發應用程式，您將保護使用者的隱私權和法定權利。如果使用者提供您使用者名稱、密碼或是其他登入資訊或個人資訊，您必須告知使用者這類資訊將提供給您的應用程式使用，並且必須為這些使用者提供法定充分的隱私權通知和保護。如果您的應用程式會儲存使用者所提供的個人或敏感資訊，它必須確保這些資訊安全無虞。如果使用者提供 Google 帳戶資訊給您，則只有在每個使用者已授權您存取其 Google 帳戶並僅限用於使用者所授權之用途的情況下，您的應用程式才能使用該資訊來存取使用者的 Google 帳戶。
+
+4.4 您同意不會使用此「預覽版」從事任何不當Activity，例如開發或散佈會以未經授權的方式干擾、妨礙、損害或存取 Google 或任何第三方之伺服器、網路或是其他財產或服務的應用程式。
+
+4.5 您同意對您透過 Android 裝置和 (或) Android 應用程式建立、傳輸或顯示的任何資料、內容或資源，以及上述行為造成的後果 (包括 Google 可能蒙受的任何損失或損害) 負起全責 (而 Google 對您或任何第三方就上述一切不需負任何責任)。
+
+4.6 您同意對違反在此「授權協議」、任何適用之第三方合約或《服務條款》或是任何適用之法律或規定下所必須遵守的義務，以及違反相關義務造成的後果 (包括 Google 或任何第三方可能蒙受的任何損失或損害) 負起全責 (而 Google 對您或任何第三方就上述一切不需負任何責任)。
+
+4.7「預覽版」目前正在開發中，因此您的測試與意見反應對開發程序非常重要。使用「預覽版」，您即認同某些功能仍處於開發階段，因此您不應期待「預覽版」擁有穩定版本的完整功能。在官方 Android SDK 發行之後，此「預覽版」不再受到支援時，您同意不使用此「預覽版」公開散佈或隨附任何應用程式。
+
+5.您的開發人員認證
+
+5.1 您同意負責保密 Google 可能核發給您或您自己選擇的任何開發人員認證，並且對在您開發人員認證名義下開發的所有應用程式負起全責。
+
+6.隱私權和資訊
+
+6.1 為了持續更新及改進此「預覽版」，Google 可能會從軟體收集某些使用狀況統計數據，包括但不限於軟體的唯一識別碼、相關 IP 位址、版本號碼，以及有關使用此「預覽版」中的哪些工具和 (或) 服務及其使用方式的相關資訊。在收集這類資訊之前，此「預覽版」會先通知您並徵求您的同意。如果您不同意，Google 將不會收集這類資訊。
+
+6.2 Google 會彙總並檢查收集到的資料，據以改善此「預覽版」，並且會依據《Google 隱私權政策》(http://www.google.com/policies/privacy/) 加以妥善保存。
+
+7.第三方應用程式
+
+7.1 如果您使用此「預覽版」來執行第三方開發的應用程式，或是執行會存取第三方所提供之資料、內容或資源的應用程式，您同意 Google 不需對這類應用程式、資料、內容或資源負任何責任。您瞭解您透過第三方應用程式存取的所有資料、內容或資源是由其提供者負起全責，而 Google 對您因使用或存取任何這些第三方應用程式、資料、內容或資源所造成的損失或損害不需負任何責任。
+
+7.2 您瞭解第三方應用程式提供給您的資料、內容或資源可能受到提供者 (或代表他們的其他人員或公司) 所擁有的智慧財產權保護。您不得根據這類資料、內容或資源 (不論是整個或部分) 修改、出租、出借、販售、散佈或製作衍生成品，除非相關擁有者明確授權您從事上述活動。
+
+7.3 您瞭解使用第三方應用程式、資料、內容或資源可能受到您與相關第三方之間的個別條款約束。
+
+8.使用 Google API
+
+8.1 Google API
+
+8.1.1 如果您使用任何 API 從 Google 擷取資料，您瞭解這些資料可能受到 Google 或資料提供者 (或代表他們的其他人員或公司) 所擁有的智慧財產權保護。您對任何這類 API 的使用可能受到其他《服務條款》約束。除非相關《服務條款》明文允許，否則您不得根據這類資料 (不論是整個或部分) 修改、出租、出借、販售、散佈或製作衍生成品。
+
+8.1.2 使用任何 API 從 Google 擷取使用者的資料時，您瞭解並同意只有在該使用者明確同意且授權您擷取其資料，而且僅限用於使用者所授權之用途的情況下，您才能擷取資料。
+
+9.終止「授權協議」
+
+9.1 除非您或 Google 終止「授權協議」(請見下方說明)，否則「授權協議」將持續具有效力。
+
+9.2 如果想終止「授權協議」，只要停止使用此「預覽版」及任何相關的開發人員憑證即可。
+
+9.3 Google 可隨時通知您終止「授權協議」，無論有無原因。
+
+9.4「授權協議」在先發生下列任一情況時，將自動終止而不另行通知或採取其他行動：
+(A) Google 決定不再提供此「預覽版」或此「預覽版」的特定部分給您所居住或使用此服務之國家/地區的使用者；或
+(B) Google 發行最終版本的 Android SDK。
+
+9.5 當「授權條款」終止時，您在「授權協議」所獲得的授權也將會一併終止，您將立即停止「預覽版」的所有使用，而第 10、11、12 和 14 項的條款將無限期持續適用。
+
+10.免責聲明
+
+10.1 您明確瞭解並同意完全自負使用此「預覽版」的風險，並且此「預覽版」是依「現況」和「可提供性」提供，Google 不負任何擔保責任。
+
+10.2 您對使用此「預覽版」及透過此「預覽版」以下載或其他方式取得的任何內容，需自行斟酌和自負風險，而且您對因這類使用而對您的電腦系統或其他裝置所造成的任何損害或資料遺失，需負起全責。不限於前述，您瞭解此「預覽版」不是穩定的版本，可能會包含許多錯誤、瑕疵和安全性弱點而對您的電腦系統或其他裝置造成嚴重的損害，包括完全、不可回復的損失。
+
+10.3 Google 進一步明確表示不提供任何形式的瑕疵擔保和條件 (不論明示或默示)，包括但不限於適售性、適合特定用途及未侵權的默示擔保和條件。
+
+11.責任限制
+
+11.1 您明確瞭解並同意在任何歸責理論下，就可能由您引起的任何直接、間接、附隨性、特殊性、衍生性或懲罰性損害賠償 (包括任何資料遺失)，不論 Google 或其代表是否已獲告知或應已瞭解發生任何這類損失的可能性，Google、其子公司和關係企業及其授權人不必對您負起任何責任。
+
+12.賠償
+
+12.1 在法律允許的最大範圍內，您同意為 Google、其子公司及其個別董監事、主管、員工和代理人，就任何和一切索賠、法律行動、訴訟或訴訟程序，以及因下列原因而引起的任何和一切損失、責任、損害賠償、費用及開支 (包括合理的律師費)，提供辯護、賠償損失並確保其免於承擔賠償責任：(a) 您使用此「預覽版」；(b) 您使用此「預覽版」開發的應用程式侵害任何人的任何智慧財產權，或是詆毀任何人或違反其公開權或隱私權；以及 (c) 您未遵守「授權協議」。
+
+13.對「授權協議」做出的變更
+
+13.1 Google 可在散佈此「預覽版」的新版本時修改「授權協議」。做出這類變更後，Google 會在提供此「預覽版」的網站上提供「授權協議」的新版本。
+
+14.一般法律條款
+
+14.1「授權協議」構成您與 Google 之間的法律協議，用於管制您對此「預覽版」(不包括 Google 依據個別書面協議提供給您的任何服務) 的使用，並完全取代先前您與 Google 之間就此「預覽版」簽署的相關協議。
+
+14.2 您同意如果 Google 未行使或執行「授權協議」所含的任何法律權利或救濟 (或在任何適用法律下對 Google 有利的權益)，並不代表 Google 正式放棄權利，Google 日後仍可行使這些權利或救濟。
+
+14.3 如果經任何法院 (就此事宜依管轄權決定) 裁決「授權協議」中有任何條款無效，則該條款將自「授權協議」中移除，「授權協議」的其餘部分則不受影響。「授權協議」的其餘條款將持續具有效力且可執行。
+
+14.4 您瞭解並同意 Google 旗下子公司體系的每位成員都是「授權協議」的第三方受益人，而且這類其他公司有權直接執行和依據「授權協議」中對其授予權益 (或對其有利之權利) 的任何條款。除此之外的任何其他人員或公司皆非「授權協議」的第三方受益人。
+
+14.5 出口限制。此「預覽版」受美國出口法規約束。您必須遵守適用於此「預覽版」的所有國內和國際出口法規。這些法律包括對目的地、使用者及最終用途的限制。
+
+14.6 未事先取得 Google 事先書面核准的情況下，您不得轉讓或轉移「授權協議」，未經這類核准的任何轉讓將會失效。您不得在未事先取得 Google 書面核准的情況下，委派其「授權協議」涵蓋的責任或義務。
+
+14.7「授權協議」以及您與 Google 就「授權協議」構成的關係皆受加州法律管轄，毋須理會其法律牴觸條款。您和 Google 同意服從位於加州聖塔克拉拉 (Santa Clara, California) 郡內法院的專屬管轄權，以解決由「授權協議」產生的任何法律事務。儘管如此，您同意 Google 仍可在任何管轄權中申請禁制令救濟 (或同等類型的緊急法定救濟)。

-/**
- * Handles launching the secure camera properly even when other applications may be using the camera
- * hardware.
- *
- * When other applications (e.g., Face Unlock) are using the camera, they must close the camera to
- * allow the secure camera to open it.  Since we want to minimize the delay when opening the secure
- * camera, other apps should close the camera at the first possible opportunity (i.e., as soon as
- * the user begins swiping to go to the secure camera).
- *
- * If the camera is unavailable when the user begins to swipe, the SecureCameraLaunchManager sends a
- * broadcast to tell other apps to close the camera.  When and if the user completes their swipe to
- * launch the secure camera, the SecureCameraLaunchManager delays launching the secure camera until
- * a callback indicates that the camera has become available.  If it doesn't receive that callback
- * within a specified timeout period, the secure camera is launched anyway.
- *
- * Ideally, the secure camera would handle waiting for the camera to become available.  This allows
- * some of the time necessary to close the camera to happen in parallel with starting the secure
- * camera app.  We can't rely on all third-party camera apps to handle this.  However, an app can
- * put com.android.systemui.statusbar.phone.will_wait_for_camera_available in its meta-data to
- * indicate that it will be responsible for waiting for the camera to become available.
- *
- * It is assumed that the functions in this class, including the constructor, will be called from
- * the UI thread.
