     51  * An intent is an abstract description of an operation to be performed.  It
     52  * can be used with {@link Context#startActivity(Intent) startActivity} to
     53  * launch an {@link android.app.Activity},
     54  * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to
     55  * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components,
     56  * and {@link android.content.Context#startService} or
     57  * {@link android.content.Context#bindService} to communicate with a
     58  * background {@link android.app.Service}.
     59  *
     60  * <p>An Intent provides a facility for performing late runtime binding between the code in
     61  * different applications. Its most significant use is in the launching of activities, where it
     62  * can be thought of as the glue between activities. It is basically a passive data structure
     63  * holding an abstract description of an action to be performed.</p>
     64  *
     65  * <div class="special reference">
     66  * <h3>Developer Guides</h3>
     67  * <p>For information about how to create and resolve intents, read the
     68  * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a>
     69  * developer guide.</p>
     70  * </div>
     71  *
     72  * <a name="IntentStructure"></a>
     73  * <h3>Intent Structure</h3>
     74  * <p>The primary pieces of information in an intent are:</p>
     75  *
     76  * <ul>
     77  *   <li> <p><b>action</b> -- The general action to be performed, such as
     78  *     {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN},
     79  *     etc.</p>
     80  *   </li>
     81  *   <li> <p><b>data</b> -- The data to operate on, such as a person record
     82  *     in the contacts database, expressed as a {@link android.net.Uri}.</p>
     83  *   </li>
     84  * </ul>
     85  *
     86  *
     87  * <p>Some examples of action/data pairs are:</p>
     88  *
     89  * <ul>
     90  *   <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display
     91  *     information about the person whose identifier is "1".</p>
     92  *   </li>
     93  *   <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display
     94  *     the phone dialer with the person filled in.</p>
     95  *   </li>
     96  *   <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display
     97  *     the phone dialer with the given number filled in.  Note how the
     98  *     VIEW action does what what is considered the most reasonable thing for
     99  *     a particular URI.</p>
    100  *   </li>
    101  *   <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display
    102  *     the phone dialer with the given number filled in.</p>
    103  *   </li>
    104  *   <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit
    105  *     information about the person whose identifier is "1".</p>
    106  *   </li>
    107  *   <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display
    108  *     a list of people, which the user can browse through.  This example is a
    109  *     typical top-level entry into the Contacts application, showing you the
    110  *     list of people. Selecting a particular person to view would result in a
    111  *     new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> }
    112  *     being used to start an activity to display that person.</p>
    113  *   </li>
    114  * </ul>
    115  *
    116  * <p>In addition to these primary attributes, there are a number of secondary
    117  * attributes that you can also include with an intent:</p>
    118  *
    119  * <ul>
    120  *     <li> <p><b>category</b> -- Gives additional information about the action
    121  *         to execute.  For example, {@link #CATEGORY_LAUNCHER} means it should
    122  *         appear in the Launcher as a top-level application, while
    123  *         {@link #CATEGORY_ALTERNATIVE} means it should be included in a list
    124  *         of alternative actions the user can perform on a piece of data.</p>
    125  *     <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the
    126  *         intent data.  Normally the type is inferred from the data itself.
    127  *         By setting this attribute, you disable that evaluation and force
    128  *         an explicit type.</p>
    129  *     <li> <p><b>component</b> -- Specifies an explicit name of a component
    130  *         class to use for the intent.  Normally this is determined by looking
    131  *         at the other information in the intent (the action, data/type, and
    132  *         categories) and matching that with a component that can handle it.
    133  *         If this attribute is set then none of the evaluation is performed,
    134  *         and this component is used exactly as is.  By specifying this attribute,
    135  *         all of the other Intent attributes become optional.</p>
    136  *     <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information.
    137  *         This can be used to provide extended information to the component.
    138  *         For example, if we have a action to send an e-mail message, we could
    139  *         also include extra pieces of data here to supply a subject, body,
    140  *         etc.</p>
    141  * </ul>
    142  *
    143  * <p>Here are some examples of other operations you can specify as intents
    144  * using these additional parameters:</p>
    145  *
    146  * <ul>
    147  *   <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> --
    148  *     Launch the home screen.</p>
    149  *   </li>
    150  *   <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type
    151  *     <i>{@link android.provider.Contacts.Phones#CONTENT_URI
    152  *     vnd.android.cursor.item/phone}</i></b>
    153  *     -- Display the list of people's phone numbers, allowing the user to
    154  *     browse through them and pick one and return it to the parent activity.</p>
    155  *   </li>
    156  *   <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type
    157  *     <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b>
    158  *     -- Display all pickers for data that can be opened with
    159  *     {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()},
    160  *     allowing the user to pick one of them and then some data inside of it
    161  *     and returning the resulting URI to the caller.  This can be used,
    162  *     for example, in an e-mail application to allow the user to pick some
    163  *     data to include as an attachment.</p>
    164  *   </li>
    165  * </ul>
    166  *
    167  * <p>There are a variety of standard Intent action and category constants
    168  * defined in the Intent class, but applications can also define their own.
    169  * These strings use java style scoping, to ensure they are unique -- for
    170  * example, the standard {@link #ACTION_VIEW} is called
    171  * "android.intent.action.VIEW".</p>
    172  *
    173  * <p>Put together, the set of actions, data types, categories, and extra data
    174  * defines a language for the system allowing for the expression of phrases
    175  * such as "call john smith's cell".  As applications are added to the system,
    176  * they can extend this language by adding new actions, types, and categories, or
    177  * they can modify the behavior of existing phrases by supplying their own
    178  * activities that handle them.</p>
    179  *
    180  * <a name="IntentResolution"></a>
    181  * <h3>Intent Resolution</h3>
    182  *
    183  * <p>There are two primary forms of intents you will use.
    184  *
    185  * <ul>
    186  *     <li> <p><b>Explicit Intents</b> have specified a component (via
    187  *     {@link #setComponent} or {@link #setClass}), which provides the exact
    188  *     class to be run.  Often these will not include any other information,
    189  *     simply being a way for an application to launch various internal
    190  *     activities it has as the user interacts with the application.
    191  *
    192  *     <li> <p><b>Implicit Intents</b> have not specified a component;
    193  *     instead, they must include enough information for the system to
    194  *     determine which of the available components is best to run for that
    195  *     intent.
    196  * </ul>
    197  *
    198  * <p>When using implicit intents, given such an arbitrary intent we need to
    199  * know what to do with it. This is handled by the process of <em>Intent
    200  * resolution</em>, which maps an Intent to an {@link android.app.Activity},
    201  * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or
    202  * more activities/receivers) that can handle it.</p>
    203  *
    204  * <p>The intent resolution mechanism basically revolves around matching an
    205  * Intent against all of the &lt;intent-filter&gt; descriptions in the
    206  * installed application packages.  (Plus, in the case of broadcasts, any {@link BroadcastReceiver}
    207  * objects explicitly registered with {@link Context#registerReceiver}.)  More
    208  * details on this can be found in the documentation on the {@link
    209  * IntentFilter} class.</p>
    210  *
    211  * <p>There are three pieces of information in the Intent that are used for
    212  * resolution: the action, type, and category.  Using this information, a query
    213  * is done on the {@link PackageManager} for a component that can handle the
    214  * intent. The appropriate component is determined based on the intent
    215  * information supplied in the <code>AndroidManifest.xml</code> file as
    216  * follows:</p>
    217  *
    218  * <ul>
    219  *     <li> <p>The <b>action</b>, if given, must be listed by the component as
    220  *         one it handles.</p>
    221  *     <li> <p>The <b>type</b> is retrieved from the Intent's data, if not
    222  *         already supplied in the Intent.  Like the action, if a type is
    223  *         included in the intent (either explicitly or implicitly in its
    224  *         data), then this must be listed by the component as one it handles.</p>
    225  *     <li> For data that is not a <code>content:</code> URI and where no explicit
    226  *         type is included in the Intent, instead the <b>scheme</b> of the
    227  *         intent data (such as <code>http:</code> or <code>mailto:</code>) is
    228  *         considered. Again like the action, if we are matching a scheme it
    229  *         must be listed by the component as one it can handle.
    230  *     <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed
    231  *         by the activity as categories it handles.  That is, if you include
    232  *         the categories {@link #CATEGORY_LAUNCHER} and
    233  *         {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components
    234  *         with an intent that lists <em>both</em> of those categories.
    235  *         Activities will very often need to support the
    236  *         {@link #CATEGORY_DEFAULT} so that they can be found by
    237  *         {@link Context#startActivity Context.startActivity()}.</p>
    238  * </ul>
    239  *
    240  * <p>For example, consider the Note Pad sample application that
    241  * allows user to browse through a list of notes data and view details about
    242  * individual items.  Text in italics indicate places were you would replace a
    243  * name with one specific to your own package.</p>

    302  * <p>The first activity,
    303  * <code>com.android.notepad.NotesList</code>, serves as our main

    305  * templates:
    306  * <ol>
    307  * <li><pre>
    308  * &lt;intent-filter&gt;
    309  *     &lt;action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /&gt;
    310  *     &lt;category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /&gt;
    311  * &lt;/intent-filter&gt;</pre>
    312  * <p>This provides a top-level entry into the NotePad application: the standard
    313  * MAIN action is a main entry point (not requiring any other information in
    314  * the Intent), and the LAUNCHER category says that this entry point should be
    315  * listed in the application launcher.</p>
    316  * <li><pre>
    317  * &lt;intent-filter&gt;
    318  *     &lt;action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /&gt;
    319  *     &lt;action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /&gt;
    320  *     &lt;action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /&gt;

    322  *     &lt;data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /&gt;
    323  * &lt;/intent-filter&gt;</pre>
    324  * <p>This declares the things that the activity can do on a directory of
    325  * notes.  The type being supported is given with the &lt;type&gt; tag, where
    326  * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which
    327  * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can
    328  * be retrieved which holds our note pad data (<code>vnd.google.note</code>).
    329  * The activity allows the user to view or edit the directory of data (via
    330  * the VIEW and EDIT actions), or to pick a particular note and return it
    331  * to the caller (via the PICK action).  Note also the DEFAULT category
    332  * supplied here: this is <em>required</em> for the
    333  * {@link Context#startActivity Context.startActivity} method to resolve your
    334  * activity when its component name is not explicitly specified.</p>
    335  * <li><pre>
    336  * &lt;intent-filter&gt;
    337  *     &lt;action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /&gt;
    338  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
    339  *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
    340  * &lt;/intent-filter&gt;</pre>
    341  * <p>This filter describes the ability return to the caller a note selected by
    342  * the user without needing to know where it came from.  The data type
    343  * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which
    344  * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can
    345  * be retrieved which contains our note pad data (<code>vnd.google.note</code>).
    346  * The GET_CONTENT action is similar to the PICK action, where the activity
    347  * will return to its caller a piece of data selected by the user.  Here,
    348  * however, the caller specifies the type of data they desire instead of
    349  * the type of data the user will be picking from.</p>
    350  * </ol>
    351  *
    352  * <p>Given these capabilities, the following intents will resolve to the
    353  * NotesList activity:</p>
    354  *
    355  * <ul>
    356  *     <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the
    357  *         activities that can be used as top-level entry points into an
    358  *         application.</p>
    359  *     <li> <p><b>{ action=android.app.action.MAIN,
    360  *         category=android.app.category.LAUNCHER }</b> is the actual intent
    361  *         used by the Launcher to populate its top-level list.</p>
    362  *     <li> <p><b>{ action=android.intent.action.VIEW
    363  *          data=content://com.google.provider.NotePad/notes }</b>
    364  *         displays a list of all the notes under
    365  *         "content://com.google.provider.NotePad/notes", which
    366  *         the user can browse through and see the details on.</p>
    367  *     <li> <p><b>{ action=android.app.action.PICK
    368  *          data=content://com.google.provider.NotePad/notes }</b>
    369  *         provides a list of the notes under
    370  *         "content://com.google.provider.NotePad/notes", from which
    371  *         the user can pick a note whose data URL is returned back to the caller.</p>
    372  *     <li> <p><b>{ action=android.app.action.GET_CONTENT
    373  *          type=vnd.android.cursor.item/vnd.google.note }</b>
    374  *         is similar to the pick action, but allows the caller to specify the
    375  *         kind of data they want back so that the system can find the appropriate
    376  *         activity to pick something of that data type.</p>
    377  * </ul>
    378  *
    379  * <p>The second activity,
    380  * <code>com.android.notepad.NoteEditor</code>, shows the user a single
    381  * note entry and allows them to edit it.  It can do two things as described
    382  * by its two intent templates:
    383  * <ol>
    384  * <li><pre>
    385  * &lt;intent-filter android:label="@string/resolve_edit"&gt;
    386  *     &lt;action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /&gt;
    387  *     &lt;action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /&gt;
    388  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
    389  *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
    390  * &lt;/intent-filter&gt;</pre>
    391  * <p>The first, primary, purpose of this activity is to let the user interact
    392  * with a single note, as decribed by the MIME type
    393  * <code>vnd.android.cursor.item/vnd.google.note</code>.  The activity can
    394  * either VIEW a note or allow the user to EDIT it.  Again we support the
    395  * DEFAULT category to allow the activity to be launched without explicitly
    396  * specifying its component.</p>
    397  * <li><pre>
    398  * &lt;intent-filter&gt;
    399  *     &lt;action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /&gt;
    400  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
    401  *     &lt;data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /&gt;
    402  * &lt;/intent-filter&gt;</pre>
    403  * <p>The secondary use of this activity is to insert a new note entry into
    404  * an existing directory of notes.  This is used when the user creates a new
    405  * note: the INSERT action is executed on the directory of notes, causing
    406  * this activity to run and have the user create the new note data which
    407  * it then adds to the content provider.</p>
    408  * </ol>
    409  *
    410  * <p>Given these capabilities, the following intents will resolve to the
    411  * NoteEditor activity:</p>
    412  *
    413  * <ul>
    414  *     <li> <p><b>{ action=android.intent.action.VIEW
    415  *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
    416  *         shows the user the content of note <var>{ID}</var>.</p>
    417  *     <li> <p><b>{ action=android.app.action.EDIT
    418  *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
    419  *         allows the user to edit the content of note <var>{ID}</var>.</p>
    420  *     <li> <p><b>{ action=android.app.action.INSERT
    421  *          data=content://com.google.provider.NotePad/notes }</b>
    422  *         creates a new, empty note in the notes list at
    423  *         "content://com.google.provider.NotePad/notes"
    424  *         and allows the user to edit it.  If they keep their changes, the URI
    425  *         of the newly created note is returned to the caller.</p>
    426  * </ul>
    427  *
    428  * <p>The last activity,
    429  * <code>com.android.notepad.TitleEditor</code>, allows the user to
    430  * edit the title of a note.  This could be implemented as a class that the
    431  * application directly invokes (by explicitly setting its component in
    432  * the Intent), but here we show a way you can publish alternative
    433  * operations on existing data:</p>
    434  *
    435  * <pre>
    436  * &lt;intent-filter android:label="@string/resolve_title"&gt;
    437  *     &lt;action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /&gt;
    438  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
    439  *     &lt;category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /&gt;
    440  *     &lt;category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /&gt;
    441  *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
    442  * &lt;/intent-filter&gt;</pre>
    443  *
    444  * <p>In the single intent template here, we
    445  * have created our own private action called
    446  * <code>com.android.notepad.action.EDIT_TITLE</code> which means to
    447  * edit the title of a note.  It must be invoked on a specific note
    448  * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous
    449  * view and edit actions, but here displays and edits the title contained
    450  * in the note data.
    451  *
    452  * <p>In addition to supporting the default category as usual, our title editor
    453  * also supports two other standard categories: ALTERNATIVE and
    454  * SELECTED_ALTERNATIVE.  Implementing
    455  * these categories allows others to find the special action it provides
    456  * without directly knowing about it, through the
    457  * {@link android.content.pm.PackageManager#queryIntentActivityOptions} method, or
    458  * more often to build dynamic menu items with
    459  * {@link android.view.Menu#addIntentOptions}.  Note that in the intent
    460  * template here was also supply an explicit name for the template
    461  * (via <code>android:label="@string/resolve_title"</code>) to better control
    462  * what the user sees when presented with this activity as an alternative
    463  * action to the data they are viewing.
    464  *
    465  * <p>Given these capabilities, the following intent will resolve to the
    466  * TitleEditor activity:</p>
    467  *
    468  * <ul>
    469  *     <li> <p><b>{ action=com.android.notepad.action.EDIT_TITLE
    470  *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
    471  *         displays and allows the user to edit the title associated
    472  *         with note <var>{ID}</var>.</p>
    473  * </ul>
    474  *
    475  * <h3>Standard Activity Actions</h3>
    476  *
    477  * <p>These are the current standard actions that Intent defines for launching
    478  * activities (usually through {@link Context#startActivity}.  The most
    479  * important, and by far most frequently used, are {@link #ACTION_MAIN} and
    480  * {@link #ACTION_EDIT}.
    481  *
    482  * <ul>
    483  *     <li> {@link #ACTION_MAIN}
    484  *     <li> {@link #ACTION_VIEW}
    485  *     <li> {@link #ACTION_ATTACH_DATA}
    486  *     <li> {@link #ACTION_EDIT}
    487  *     <li> {@link #ACTION_PICK}
    488  *     <li> {@link #ACTION_CHOOSER}

    495  *     <li> {@link #ACTION_INSERT}
    496  *     <li> {@link #ACTION_DELETE}

    502  *     <li> {@link #ACTION_FACTORY_TEST}
    503  * </ul>
    504  *
    505  * <h3>Standard Broadcast Actions</h3>
    506  *
    507  * <p>These are the current standard actions that Intent defines for receiving
    508  * broadcasts (usually through {@link Context#registerReceiver} or a
    509  * &lt;receiver&gt; tag in a manifest).
    510  *
    511  * <ul>
    512  *     <li> {@link #ACTION_TIME_TICK}
    513  *     <li> {@link #ACTION_TIME_CHANGED}
    514  *     <li> {@link #ACTION_TIMEZONE_CHANGED}
    515  *     <li> {@link #ACTION_BOOT_COMPLETED}
    516  *     <li> {@link #ACTION_PACKAGE_ADDED}
    517  *     <li> {@link #ACTION_PACKAGE_CHANGED}
    518  *     <li> {@link #ACTION_PACKAGE_REMOVED}
    519  *     <li> {@link #ACTION_PACKAGE_RESTARTED}
    520  *     <li> {@link #ACTION_PACKAGE_DATA_CLEARED}
    521  *     <li> {@link #ACTION_UID_REMOVED}
    522  *     <li> {@link #ACTION_BATTERY_CHANGED}
    523  *     <li> {@link #ACTION_POWER_CONNECTED}
    524  *     <li> {@link #ACTION_POWER_DISCONNECTED}
    525  *     <li> {@link #ACTION_SHUTDOWN}
    526  * </ul>
    527  *
    528  * <h3>Standard Categories</h3>
    529  *
    530  * <p>These are the current standard categories that can be used to further
    531  * clarify an Intent via {@link #addCategory}.
    532  *
    533  * <ul>
    534  *     <li> {@link #CATEGORY_DEFAULT}
    535  *     <li> {@link #CATEGORY_BROWSABLE}
    536  *     <li> {@link #CATEGORY_TAB}
    537  *     <li> {@link #CATEGORY_ALTERNATIVE}
    538  *     <li> {@link #CATEGORY_SELECTED_ALTERNATIVE}
    539  *     <li> {@link #CATEGORY_LAUNCHER}
    540  *     <li> {@link #CATEGORY_INFO}
    541  *     <li> {@link #CATEGORY_HOME}
    542  *     <li> {@link #CATEGORY_PREFERENCE}
    543  *     <li> {@link #CATEGORY_TEST}
    544  *     <li> {@link #CATEGORY_CAR_DOCK}
    545  *     <li> {@link #CATEGORY_DESK_DOCK}
    546  *     <li> {@link #CATEGORY_LE_DESK_DOCK}
    547  *     <li> {@link #CATEGORY_HE_DESK_DOCK}
    548  *     <li> {@link #CATEGORY_CAR_MODE}
    549  *     <li> {@link #CATEGORY_APP_MARKET}
    550  * </ul>
    551  *
    552  * <h3>Standard Extra Data</h3>
    553  *
    554  * <p>These are the current standard fields that can be used as extra data via
    555  * {@link #putExtra}.
    556  *

    588  *
    589  * <h3>Flags</h3>
    590  *
    591  * <p>These are the possible flags that can be used in the Intent via

    890      * There are two main ways to use this action: if you want a specific kind

    898      * user to add an attachment to an e-mail message can use this action to
    899      * bring up a list of all of the types of content the user can attach.
    900      * <p>
    901      * In this case, you should wrap the GET_CONTENT intent with a chooser
    902      * (through {@link #createChooser}), which will give the proper interface
    903      * for the user to pick how to send your data and allow you to specify

    909      * only pick from data that can be represented as a stream.  This is
    910      * accomplished by requiring the {@link #CATEGORY_OPENABLE} in the Intent.
    911      * <p>
    912      * Callers can optionally specify {@link #EXTRA_LOCAL_ONLY} to request that
    913      * the launched content chooser only returns results representing data that

   4829      *
   4830      * <p>An example of where this may be used is with things like
   4831      * {@link #CATEGORY_APP_BROWSER}.  This category allows you to build an
   4832      * Intent that will launch the Browser application.  However, the correct
   4833      * main entry point of an application is actually {@link #ACTION_MAIN}
   4834      * {@link #CATEGORY_LAUNCHER} with {@link #setComponent(ComponentName)}
   4835      * used to specify the actual Activity to launch.  If you launch the browser
   4836      * with something different, undesired behavior may happen if the user has
   4837      * previously or later launches it the normal way, since they do not match.
   4838      * Instead, you can build an Intent with the MAIN action (but no ComponentName
   4839      * yet specified) and set a selector with {@link #ACTION_MAIN} and
   4840      * {@link #CATEGORY_APP_BROWSER} to point it specifically to the browser activity.
   4841      *
   4842      * <p>Setting a selector does not impact the behavior of
   4843      * {@link #filterEquals(Intent)} and {@link #filterHashCode()}.  This is part of the
   4844      * desired behavior of a selector -- it does not impact the base meaning
   4845      * of the Intent, just what kinds of things will be matched against it
   4846      * when determining who can handle it.</p>
   4847      *
