+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.

+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.
+
+4.2 계약자는 (a) 본 라이선스 계약 그리고 (b) 모든 준거법, 규정 또는 관련 관할권 내에서 일반적으로 수용되는 관행 또는 지침(미국 또는 기타 관련 국가로/에서의 데이터 또는 소프트웨어 수출과 관련된 모든 법률 포함)에서 허용하는 용도에 한하여 미리 보기를 사용하고 애플리케이션을 작성하는 것에 동의합니다.
+
+4.3 계약자는 일반 대중 사용자를 대상으로 미리 보기를 사용하여 애플리케이션을 개발하는 경우, 해당 사용자의 프라이버시 및 법적 권리를 보호하는 것에 동의합니다. 사용자가 계약자에게 사용자 이름, 비밀번호 또는 기타 로그인 정보나 개인 정보를 제공하는 경우, 계약자는 제공된 정보가 자신의 애플리케이션에 제공된다는 사실을 사용자에게 알려야 하며, 반드시 법적으로 적절한 개인정보 보호정책 고지 및 보호를 해당 사용자에게 제공해야 합니다. 애플리케이션에서 사용자가 제공한 개인정보나 민감한 정보를 저장하는 경우, 이를 안전하게 처리해야 합니다. 사용자들이 애플리케이션에 Google 계정 정보를 제공하는 경우, 애플리케이션은 해당 사용자의 Google 계정에 액세스하는 목적으로만, 그리고 각 사용자가 허용한 범위 내의 한정된 목적으로만 이러한 정보를 사용해야 합니다.
+
+4.4 계약자는 Google 또는 기타 모든 타사의 서버, 네트워크 또는 기타 모든 재산 또는 서비스를 허가 없이 방해, 교란, 손상 또는 액세스하는 애플리케이션의 개발 또는 배포를 포함한 하등의 행위에 미리 보기를 이용하지 않을 것임을 동의합니다.
+
+4.5 계약자는 자신이 Android 및/또는 Android용 애플리케이션을 통해 생성, 전송 또는 표시하는 모든 데이터, 콘텐츠 또는 리소스 그리고 그로 인한 결과(Google이 입을 수 있는 모든 피해나 손실 포함)에 대해 전적으로 책임이 있다는 것(그리고 Google은 계약자 또는 모든 제3자에 대한 책임이 없다는 것)에 동의합니다.
+
+4.6 계약자는 본 라이선스 계약, 모든 해당 제3자 계약 또는 서비스 약관, 또는 모든 준거법 또는 규정에 의거한 계약자 의무 위반, 그리고 그로 인한 결과(Google 또는 제3자가 입을 수 있는 모든 피해나 손실 포함)에 전적으로 책임이 있다는 것(그리고 Google은 계약자 또는 모든 제3자에 대한 책임이 없다는 것)에 동의합니다.
+
+4.7 이 미리 보기는 현재 개발 단계에 있으며, 계약자의 테스트와 피드백은 그러한 개발 과정에 중요한 부분을 차지합니다. 미리 보기를 사용함으로써 계약자는 일부 기능의 구현은 아직 개발 중인 상태이며 미리 보기가 안정된 릴리스처럼 완벽하게 기능할 것이라 믿고 사용해서는 안 된다는 점을 인지하는 것으로 간주합니다. 계약자는 이 미리 보기를 사용한 애플리케이션을 공개적으로 배포 또는 배송하지 않기로 동의합니다. 이 미리 보기는 공식 Android SDK가 출시된 이후에는 더 이상 지원되지 않기 때문입니다.
+
+5. 계약자의 개발자 자격 증명
+
+5.1 계약자는 Google이 발급했거나 자신이 선택한 모든 개발자 자격 증명에 대한 기밀성을 유지할 책임이 있으며 계약자의 개발자 자격 증명 하에 개발된 모든 애플리케이션에 대한 전적인 책임이 있음에 동의합니다.

+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.
+
+6.2. Собранные данные изучаются в обобщенном виде с целью улучшения Preview и хранятся в соответствии с Политикой конфиденциальности Google, которая опубликована на веб-сайте по адресу http://www.google.com/policies/privacy/.
+
+7. Сторонние приложения
+
+7.1. Если вы используете Preview для запуска приложений, разработанных третьими сторонами или получающих доступ к данным, содержимому или ресурсам, предоставляемым третьей стороной, вы соглашаетесь с тем, что Google не несет ответственности за такие приложения, данные, содержимое или ресурсы. Вы осознаете, что единоличную ответственность за все данные, содержимое или ресурсы, доступ к которым вы можете получить посредством таких приложений третьих сторон, несет лицо, предоставившее их, а также то, что Google не несет ответственности за любые убытки или любой ущерб, которые могут возникнуть в результате использования вами любых таких сторонних приложений, данных, содержимого или ресурсов и в результате обращения к ним.
+
+7.2. Вы должны быть осведомлены о том, что данные, содержимое и ресурсы, предоставляемые вам посредством таких сторонних приложений, могут быть защищены правами на объекты интеллектуальной собственности, принадлежащие предоставляющим их лицам (или иным лицам либо компаниям от их имени). Вам запрещается изменять, сдавать в аренду, передавать, продавать, распространять такие данные, содержимое или ресурсы (полностью или частично), а также создавать на их основе производные элементы, если у вас нет на это разрешения от соответствующих владельцев.
+
+7.3. Вы осознаете, что использование вами таких сторонних приложений, данных или ресурсов может регулироваться отдельными условиями, заключенными между вами и соответствующей третьей стороной.
+

+
+8.1.1. В случае использования вами любых API для получения данных из Google вы осознаете, что такие данные могут быть защищены правами на объекты интеллектуальной собственности, принадлежащие Google или предоставляющим их сторонам (или иным лицам либо компаниям от их имени). Использование вами подобных API может регулироваться дополнительными Условиями использования. Вам запрещается изменять, сдавать в аренду, передавать, продавать, распространять такие данные (полностью или частично), а также создавать на их основе производные элементы, если это не разрешено соответствующими Условиями использования.
+
+8.1.2. Если вы используете какие-либо API-интерфейсы для получения данных пользователя из Google, вы осознаете и соглашаетесь с тем, что вы обязуетесь получать такие данные исключительно с прямого согласия пользователя и только в тех целях, которые обозначил пользователь.

+
+14.3.

+
+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。

+
+3.6 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）。

+
+4.7 “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。

+
+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。

+
+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。

+
+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」。

+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)。
