+/**
+ * An intent is an abstract description of an operation to be performed. It
+ * can be used with {@link Context#startActivity(Intent) startActivity} to
+ * launch an {@link android.app.Activity},
+ * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to
+ * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components,
+ * and {@link android.content.Context#startService} or
+ * {@link android.content.Context#bindService} to communicate with a
+ * background {@link android.app.Service}.
+ *
+ * <p>An Intent provides a facility for performing late runtime binding between
+ * the code in different applications. Its most significant use is in the
+ * launching of activities, where it can be thought of as the glue between
+ * activities. It is
+ * basically a passive data structure holding an abstract description of an
+ * action to be performed. The primary pieces of information in an intent
+ * are:</p>
+ *
+ * <ul>
+ * <li> <p><b>action</b> -- The general action to be performed, such as
+ * {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN},
+ * etc.</p>
+ * </li>
+ * <li> <p><b>data</b> -- The data to operate on, such as a person record
+ * in the contacts database, expressed as a {@link android.net.Uri}.</p>
+ * </li>
+ * </ul>
+ *
+ *
+ * <p>Some examples of action/data pairs are:</p>
+ *
+ * <ul>
+ * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/1</i></b> -- Display
+ * information about the person whose identifier is "1".</p>
+ * </li>
+ * <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/1</i></b> -- Display
+ * the phone dialer with the person filled in.</p>
+ * </li>
+ * <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display
+ * the phone dialer with the given number filled in. Note how the
+ * VIEW action does what what is considered the most reasonable thing for
+ * a particular URI.</p>
+ * </li>
+ * <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display
+ * the phone dialer with the given number filled in.</p>
+ * </li>
+ * <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/1</i></b> -- Edit
+ * information about the person whose identifier is "1".</p>
+ * </li>
+ * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/</i></b> -- Display
+ * a list of people, which the user can browse through. This example is a
+ * typical top-level entry into the Contacts application, showing you the
+ * list of people. Selecting a particular person to view would result in a
+ * new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> }
+ * being used to start an activity to display that person.</p>
+ * </li>
+ * </ul>
+ *
+ * <p>In addition to these primary attributes, there are a number of secondary
+ * attributes that you can also include with an intent:</p>
+ *
+ * <ul>
+ * <li> <p><b>category</b> -- Gives additional information about the action
+ * to execute. For example, {@link #CATEGORY_LAUNCHER} means it should
+ * appear in the Launcher as a top-level application, while
+ * {@link #CATEGORY_ALTERNATIVE} means it should be included in a list
+ * of alternative actions the user can perform on a piece of data.</p>
+ * <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the
+ * intent data. Normally the type is inferred from the data itself.
+ * By setting this attribute, you disable that evaluation and force
+ * an explicit type.</p>
+ * <li> <p><b>component</b> -- Specifies an explicit name of a component
+ * class to use for the intent. Normally this is determined by looking
+ * at the other information in the intent (the action, data/type, and
+ * categories) and matching that with a component that can handle it.
+ * If this attribute is set then none of the evaluation is performed,
+ * and this component is used exactly as is. By specifying this attribute,
+ * all of the other Intent attributes become optional.</p>
+ * <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information.
+ * This can be used to provide extended information to the component.
+ * For example, if we have a action to send an e-mail message, we could
+ * also include extra pieces of data here to supply a subject, body,
+ * etc.</p>
+ * </ul>
+ *
+ * <p>Here are some examples of other operations you can specify as intents
+ * using these additional parameters:</p>
+ *
+ * <ul>
+ * <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> --
+ * Launch the home screen.</p>
+ * </li>
+ * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type
+ * <i>{@link android.provider.Contacts.Phones#CONTENT_URI
+ * vnd.android.cursor.item/phone}</i></b>
+ * -- Display the list of people's phone numbers, allowing the user to
+ * browse through them and pick one and return it to the parent activity.</p>
+ * </li>
+ * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type
+ * <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b>
+ * -- Display all pickers for data that can be opened with
+ * {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()},
+ * allowing the user to pick one of them and then some data inside of it
+ * and returning the resulting URI to the caller. This can be used,
+ * for example, in an e-mail application to allow the user to pick some
+ * data to include as an attachment.</p>
+ * </li>
+ * </ul>
+ *
+ * <p>There are a variety of standard Intent action and category constants
+ * defined in the Intent class, but applications can also define their own.
+ * These strings use java style scoping, to ensure they are unique -- for
+ * example, the standard {@link #ACTION_VIEW} is called
+ * "android.app.action.VIEW".</p>
+ *
+ * <p>Put together, the set of actions, data types, categories, and extra data
+ * defines a language for the system allowing for the expression of phrases
+ * such as "call john smith's cell". As applications are added to the system,
+ * they can extend this language by adding new actions, types, and categories, or
+ * they can modify the behavior of existing phrases by supplying their own
+ * activities that handle them.</p>
+ *
+ * <a name="IntentResolution"></a>
+ * <h3>Intent Resolution</h3>
+ *
+ * <p>There are two primary forms of intents you will use.
+ *
+ * <ul>
+ * <li> <p><b>Explicit Intents</b> have specified a component (via
+ * {@link #setComponent} or {@link #setClass}), which provides the exact
+ * class to be run. Often these will not include any other information,
+ * simply being a way for an application to launch various internal
+ * activities it has as the user interacts with the application.
+ *
+ * <li> <p><b>Implicit Intents</b> have not specified a component;
+ * instead, they must include enough information for the system to
+ * determine which of the available components is best to run for that
+ * intent.
+ * </ul>
+ *
+ * <p>When using implicit intents, given such an arbitrary intent we need to
+ * know what to do with it. This is handled by the process of <em>Intent
+ * resolution</em>, which maps an Intent to an {@link android.app.Activity},
+ * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or
+ * more activities/receivers) that can handle it.</p>
+ *
+ * <p>The intent resolution mechanism basically revolves around matching an
+ * Intent against all of the <intent-filter> descriptions in the
+ * installed application packages. (Plus, in the case of broadcasts, any {@link BroadcastReceiver}
+ * objects explicitly registered with {@link Context#registerReceiver}.) More
+ * details on this can be found in the documentation on the {@link
+ * IntentFilter} class.</p>
+ *
+ * <p>There are three pieces of information in the Intent that are used for
+ * resolution: the action, type, and category. Using this information, a query
+ * is done on the {@link PackageManager} for a component that can handle the
+ * intent. The appropriate component is determined based on the intent
+ * information supplied in the <code>AndroidManifest.xml</code> file as
+ * follows:</p>
+ *
+ * <ul>
+ * <li> <p>The <b>action</b>, if given, must be listed by the component as
+ * one it handles.</p>
+ * <li> <p>The <b>type</b> is retrieved from the Intent's data, if not
+ * already supplied in the Intent. Like the action, if a type is
+ * included in the intent (either explicitly or implicitly in its
+ * data), then this must be listed by the component as one it handles.</p>
+ * <li> For data that is not a <code>content:</code> URI and where no explicit
+ * type is included in the Intent, instead the <b>scheme</b> of the
+ * intent data (such as <code>http:</code> or <code>mailto:</code>) is
+ * considered. Again like the action, if we are matching a scheme it
+ * must be listed by the component as one it can handle.
+ * <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed
+ * by the activity as categories it handles. That is, if you include
+ * the categories {@link #CATEGORY_LAUNCHER} and
+ * {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components
+ * with an intent that lists <em>both</em> of those categories.
+ * Activities will very often need to support the
+ * {@link #CATEGORY_DEFAULT} so that they can be found by
+ * {@link Context#startActivity Context.startActivity()}.</p>
+ * </ul>
+ *
+ * <p>For example, consider the Note Pad sample application that
+ * allows user to browse through a list of notes data and view details about
+ * individual items. Text in italics indicate places were you would replace a
+ * name with one specific to your own package.</p>

+ * </intent-filter>
+ * </activity>
+ *
+ * </application>
+ * </manifest></pre>
+ *
+ * <p>The first activity,
+ * <code>com.android.notepad.NotesList</code>, serves as our main
+ * entry into the app. It can do three things as described by its three intent
+ * templates:
+ * <ol>
+ * <li><pre>
+ * <intent-filter>
+ * <action android:value="{@link #ACTION_MAIN android.intent.action.MAIN}" />
+ * <category android:value="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" />
+ * </intent-filter></pre>
+ * <p>This provides a top-level entry into the NotePad application: the standard
+ * MAIN action is a main entry point (not requiring any other information in
+ * the Intent), and the LAUNCHER category says that this entry point should be
+ * listed in the application launcher.</p>
+ * <li><pre>
+ * <intent-filter>
+ * <action android:value="{@link #ACTION_VIEW android.intent.action.VIEW}" />
+ * <action android:value="{@link #ACTION_EDIT android.intent.action.EDIT}" />
+ * <action android:value="{@link #ACTION_PICK android.intent.action.PICK}" />
+ * <category android:value="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" />
+ * <type android:value="vnd.android.cursor.dir/<i>vnd.google.note</i>" />
+ * </intent-filter></pre>
+ * <p>This declares the things that the activity can do on a directory of
+ * notes. The type being supported is given with the <type> tag, where
+ * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which
+ * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can
+ * be retrieved which holds our note pad data (<code>vnd.google.note</code>).
+ * The activity allows the user to view or edit the directory of data (via
+ * the VIEW and EDIT actions), or to pick a particular note and return it
+ * to the caller (via the PICK action). Note also the DEFAULT category
+ * supplied here: this is <em>required</em> for the
+ * {@link Context#startActivity Context.startActivity} method to resolve your
+ * activity when its component name is not explicitly specified.</p>
+ * <li><pre>
+ * <intent-filter>
+ * <action android:value="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" />
+ * <category android:value="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" />
+ * <type android:value="vnd.android.cursor.item/<i>vnd.google.note</i>" />
+ * </intent-filter></pre>
+ * <p>This filter describes the ability return to the caller a note selected by
+ * the user without needing to know where it came from. The data type
+ * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which
+ * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can
+ * be retrieved which contains our note pad data (<code>vnd.google.note</code>).
+ * The GET_CONTENT action is similar to the PICK action, where the activity
+ * will return to its caller a piece of data selected by the user. Here,
+ * however, the caller specifies the type of data they desire instead of
+ * the type of data the user will be picking from.</p>
+ * </ol>
+ *
+ * <p>Given these capabilities, the following intents will resolve to the
+ * NotesList activity:</p>
+ *
+ * <ul>
+ * <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the
+ * activities that can be used as top-level entry points into an
+ * application.</p>
+ * <li> <p><b>{ action=android.app.action.MAIN,
+ * category=android.app.category.LAUNCHER }</b> is the actual intent
+ * used by the Launcher to populate its top-level list.</p>
+ * <li> <p><b>{ action=android.app.action.VIEW
+ * data=content://com.google.provider.NotePad/notes }</b>
+ * displays a list of all the notes under
+ * "content://com.google.provider.NotePad/notes", which
+ * the user can browse through and see the details on.</p>
+ * <li> <p><b>{ action=android.app.action.PICK
+ * data=content://com.google.provider.NotePad/notes }</b>
+ * provides a list of the notes under
+ * "content://com.google.provider.NotePad/notes", from which
+ * the user can pick a note whose data URL is returned back to the caller.</p>
+ * <li> <p><b>{ action=android.app.action.GET_CONTENT
+ * type=vnd.android.cursor.item/vnd.google.note }</b>
+ * is similar to the pick action, but allows the caller to specify the
+ * kind of data they want back so that the system can find the appropriate
+ * activity to pick something of that data type.</p>
+ * </ul>
+ *
+ * <p>The second activity,
+ * <code>com.android.notepad.NoteEditor</code>, shows the user a single
+ * note entry and allows them to edit it. It can do two things as described
+ * by its two intent templates:
+ * <ol>
+ * <li><pre>
+ * <intent-filter android:label="@string/resolve_edit">
+ * <action android:value="{@link #ACTION_VIEW android.intent.action.VIEW}" />
+ * <action android:value="{@link #ACTION_EDIT android.intent.action.EDIT}" />
+ * <category android:value="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" />
+ * <type android:value="vnd.android.cursor.item/<i>vnd.google.note</i>" />
+ * </intent-filter></pre>
+ * <p>The first, primary, purpose of this activity is to let the user interact
+ * with a single note, as decribed by the MIME type
+ * <code>vnd.android.cursor.item/vnd.google.note</code>. The activity can
+ * either VIEW a note or allow the user to EDIT it. Again we support the
+ * DEFAULT category to allow the activity to be launched without explicitly
+ * specifying its component.</p>
+ * <li><pre>
+ * <intent-filter>
+ * <action android:value="{@link #ACTION_INSERT android.intent.action.INSERT}" />
+ * <category android:value="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" />
+ * <type android:value="vnd.android.cursor.dir/<i>vnd.google.note</i>" />
+ * </intent-filter></pre>
+ * <p>The secondary use of this activity is to insert a new note entry into
+ * an existing directory of notes. This is used when the user creates a new
+ * note: the INSERT action is executed on the directory of notes, causing
+ * this activity to run and have the user create the new note data which
+ * it then adds to the content provider.</p>
+ * </ol>
+ *
+ * <p>Given these capabilities, the following intents will resolve to the
+ * NoteEditor activity:</p>
+ *
+ * <ul>
+ * <li> <p><b>{ action=android.app.action.VIEW
+ * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
+ * shows the user the content of note <var>{ID}</var>.</p>
+ * <li> <p><b>{ action=android.app.action.EDIT
+ * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
+ * allows the user to edit the content of note <var>{ID}</var>.</p>
+ * <li> <p><b>{ action=android.app.action.INSERT
+ * data=content://com.google.provider.NotePad/notes }</b>
+ * creates a new, empty note in the notes list at
+ * "content://com.google.provider.NotePad/notes"
+ * and allows the user to edit it. If they keep their changes, the URI
+ * of the newly created note is returned to the caller.</p>
+ * </ul>
+ *
+ * <p>The last activity,
+ * <code>com.android.notepad.TitleEditor</code>, allows the user to
+ * edit the title of a note. This could be implemented as a class that the
+ * application directly invokes (by explicitly setting its component in
+ * the Intent), but here we show a way you can publish alternative
+ * operations on existing data:</p>
+ *
+ * <pre>
+ * <intent-filter android:label="@string/resolve_title">
+ * <action android:value="<i>com.android.notepad.action.EDIT_TITLE</i>" />
+ * <category android:value="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" />
+ * <category android:value="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" />
+ * <category android:value="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" />
+ * <type android:value="vnd.android.cursor.item/<i>vnd.google.note</i>" />
+ * </intent-filter></pre>
+ *
+ * <p>In the single intent template here, we
+ * have created our own private action called
+ * <code>com.android.notepad.action.EDIT_TITLE</code> which means to
+ * edit the title of a note. It must be invoked on a specific note
+ * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous
+ * view and edit actions, but here displays and edits the title contained
+ * in the note data.
+ *
+ * <p>In addition to supporting the default category as usual, our title editor
+ * also supports two other standard categories: ALTERNATIVE and
+ * SELECTED_ALTERNATIVE. Implementing
+ * these categories allows others to find the special action it provides
+ * without directly knowing about it, through the
+ * {@link android.content.pm.PackageManager#queryIntentActivityOptions} method, or
+ * more often to build dynamic menu items with
+ * {@link android.view.Menu#addIntentOptions}. Note that in the intent
+ * template here was also supply an explicit name for the template
+ * (via <code>android:label="@string/resolve_title"</code>) to better control
+ * what the user sees when presented with this activity as an alternative
+ * action to the data they are viewing.
+ *
+ * <p>Given these capabilities, the following intent will resolve to the
+ * TitleEditor activity:</p>
+ *
+ * <ul>
+ * <li> <p><b>{ action=com.android.notepad.action.EDIT_TITLE
+ * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
+ * displays and allows the user to edit the title associated
+ * with note <var>{ID}</var>.</p>
+ * </ul>
+ *
+ * <h3>Standard Activity Actions</h3>
+ *
+ * <p>These are the current standard actions that Intent defines for launching
+ * activities (usually through {@link Context#startActivity}. The most
+ * important, and by far most frequently used, are {@link #ACTION_MAIN} and

+ * <li> {@link #ACTION_TIME_CHANGED}

+ * <li> {@link #ACTION_BATTERY_CHANGED}
+ * </ul>
+ *
+ * <h3>Standard Categories</h3>
+ *
+ * <p>These are the current standard categories that can be used to further
+ * clarify an Intent via {@link #addCategory}.
+ *
+ * <ul>
+ * <li> {@link #CATEGORY_DEFAULT}
+ * <li> {@link #CATEGORY_BROWSABLE}
+ * <li> {@link #CATEGORY_TAB}
+ * <li> {@link #CATEGORY_ALTERNATIVE}

+ * <li> {@link #CATEGORY_GADGET}
+ * <li> {@link #CATEGORY_TEST}
+ * </ul>
+ *
+ * <h3>Standard Extra Data</h3>
+ *
+ * <p>These are the current standard fields that can be used as extra data via
+ * {@link #putExtra}.
+ *
+ * <ul>
+ * <li> {@link #EXTRA_TEMPLATE}
+ * <li> {@link #EXTRA_INTENT}
+ * <li> {@link #EXTRA_STREAM}
+ * <li> {@link #EXTRA_TEXT}
+ * </ul>
