80  * An intent is an abstract description of an operation to be performed.  It
81  * can be used with {@link Context#startActivity(Intent) startActivity} to
82  * launch an {@link android.app.Activity},
83  * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to
84  * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components,
85  * and {@link android.content.Context#startService} or
86  * {@link android.content.Context#bindService} to communicate with a
87  * background {@link android.app.Service}.
88  *
89  * <p>An Intent provides a facility for performing late runtime binding between the code in
90  * different applications. Its most significant use is in the launching of activities, where it
91  * can be thought of as the glue between activities. It is basically a passive data structure
92  * holding an abstract description of an action to be performed.</p>
93  *
94  * <div class="special reference">
95  * <h3>Developer Guides</h3>
96  * <p>For information about how to create and resolve intents, read the
97  * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a>
98  * developer guide.</p>
99  * </div>
100  *
101  * <a name="IntentStructure"></a>
102  * <h3>Intent Structure</h3>
103  * <p>The primary pieces of information in an intent are:</p>
104  *
105  * <ul>
106  *   <li> <p><b>action</b> -- The general action to be performed, such as
107  *     {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN},
108  *     etc.</p>
109  *   </li>
110  *   <li> <p><b>data</b> -- The data to operate on, such as a person record
111  *     in the contacts database, expressed as a {@link android.net.Uri}.</p>
112  *   </li>
113  * </ul>
114  *
115  *
116  * <p>Some examples of action/data pairs are:</p>
117  *
118  * <ul>
119  *   <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display
120  *     information about the person whose identifier is "1".</p>
121  *   </li>
122  *   <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display
123  *     the phone dialer with the person filled in.</p>
124  *   </li>
125  *   <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display
126  *     the phone dialer with the given number filled in.  Note how the
127  *     VIEW action does what is considered the most reasonable thing for
128  *     a particular URI.</p>
129  *   </li>
130  *   <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display
131  *     the phone dialer with the given number filled in.</p>
132  *   </li>
133  *   <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit
134  *     information about the person whose identifier is "1".</p>
135  *   </li>
136  *   <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display
137  *     a list of people, which the user can browse through.  This example is a
138  *     typical top-level entry into the Contacts application, showing you the
139  *     list of people. Selecting a particular person to view would result in a
140  *     new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/people/N</i></b> }
141  *     being used to start an activity to display that person.</p>
142  *   </li>
143  * </ul>
144  *
145  * <p>In addition to these primary attributes, there are a number of secondary
146  * attributes that you can also include with an intent:</p>
147  *
148  * <ul>
149  *     <li> <p><b>category</b> -- Gives additional information about the action
150  *         to execute.  For example, {@link #CATEGORY_LAUNCHER} means it should
151  *         appear in the Launcher as a top-level application, while
152  *         {@link #CATEGORY_ALTERNATIVE} means it should be included in a list
153  *         of alternative actions the user can perform on a piece of data.</p>
154  *     <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the
155  *         intent data.  Normally the type is inferred from the data itself.
156  *         By setting this attribute, you disable that evaluation and force
157  *         an explicit type.</p>
158  *     <li> <p><b>component</b> -- Specifies an explicit name of a component
159  *         class to use for the intent.  Normally this is determined by looking
160  *         at the other information in the intent (the action, data/type, and
161  *         categories) and matching that with a component that can handle it.
162  *         If this attribute is set then none of the evaluation is performed,
163  *         and this component is used exactly as is.  By specifying this attribute,
164  *         all of the other Intent attributes become optional.</p>
165  *     <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information.
166  *         This can be used to provide extended information to the component.
167  *         For example, if we have a action to send an e-mail message, we could
168  *         also include extra pieces of data here to supply a subject, body,
169  *         etc.</p>
170  * </ul>
171  *
172  * <p>Here are some examples of other operations you can specify as intents
173  * using these additional parameters:</p>
174  *
175  * <ul>
176  *   <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> --
177  *     Launch the home screen.</p>
178  *   </li>
179  *   <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type
180  *     <i>{@link android.provider.Contacts.Phones#CONTENT_URI
181  *     vnd.android.cursor.item/phone}</i></b>
182  *     -- Display the list of people's phone numbers, allowing the user to
183  *     browse through them and pick one and return it to the parent activity.</p>
184  *   </li>
185  *   <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type
186  *     <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b>
187  *     -- Display all pickers for data that can be opened with
188  *     {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()},
189  *     allowing the user to pick one of them and then some data inside of it
190  *     and returning the resulting URI to the caller.  This can be used,
191  *     for example, in an e-mail application to allow the user to pick some
192  *     data to include as an attachment.</p>
193  *   </li>
194  * </ul>
195  *
196  * <p>There are a variety of standard Intent action and category constants
197  * defined in the Intent class, but applications can also define their own.
198  * These strings use Java-style scoping, to ensure they are unique -- for
199  * example, the standard {@link #ACTION_VIEW} is called
200  * "android.intent.action.VIEW".</p>
201  *
202  * <p>Put together, the set of actions, data types, categories, and extra data
203  * defines a language for the system allowing for the expression of phrases
204  * such as "call john smith's cell".  As applications are added to the system,
205  * they can extend this language by adding new actions, types, and categories, or
206  * they can modify the behavior of existing phrases by supplying their own
207  * activities that handle them.</p>
208  *
209  * <a name="IntentResolution"></a>
210  * <h3>Intent Resolution</h3>
211  *
212  * <p>There are two primary forms of intents you will use.
213  *
214  * <ul>
215  *     <li> <p><b>Explicit Intents</b> have specified a component (via
216  *     {@link #setComponent} or {@link #setClass}), which provides the exact
217  *     class to be run.  Often these will not include any other information,
218  *     simply being a way for an application to launch various internal
219  *     activities it has as the user interacts with the application.
220  *
221  *     <li> <p><b>Implicit Intents</b> have not specified a component;
222  *     instead, they must include enough information for the system to
223  *     determine which of the available components is best to run for that
224  *     intent.
225  * </ul>
226  *
227  * <p>When using implicit intents, given such an arbitrary intent we need to
228  * know what to do with it. This is handled by the process of <em>Intent
229  * resolution</em>, which maps an Intent to an {@link android.app.Activity},
230  * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or
231  * more activities/receivers) that can handle it.</p>
232  *
233  * <p>The intent resolution mechanism basically revolves around matching an
234  * Intent against all of the &lt;intent-filter&gt; descriptions in the
235  * installed application packages.  (Plus, in the case of broadcasts, any {@link BroadcastReceiver}
236  * objects explicitly registered with {@link Context#registerReceiver}.)  More
237  * details on this can be found in the documentation on the {@link
238  * IntentFilter} class.</p>
239  *
240  * <p>There are three pieces of information in the Intent that are used for
241  * resolution: the action, type, and category.  Using this information, a query
242  * is done on the {@link PackageManager} for a component that can handle the
243  * intent. The appropriate component is determined based on the intent
244  * information supplied in the <code>AndroidManifest.xml</code> file as
245  * follows:</p>
246  *
247  * <ul>
248  *     <li> <p>The <b>action</b>, if given, must be listed by the component as
249  *         one it handles.</p>
250  *     <li> <p>The <b>type</b> is retrieved from the Intent's data, if not
251  *         already supplied in the Intent.  Like the action, if a type is
252  *         included in the intent (either explicitly or implicitly in its
253  *         data), then this must be listed by the component as one it handles.</p>
254  *     <li> For data that is not a <code>content:</code> URI and where no explicit
255  *         type is included in the Intent, instead the <b>scheme</b> of the
256  *         intent data (such as <code>http:</code> or <code>mailto:</code>) is
257  *         considered. Again like the action, if we are matching a scheme it
258  *         must be listed by the component as one it can handle.
259  *     <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed
260  *         by the activity as categories it handles.  That is, if you include
261  *         the categories {@link #CATEGORY_LAUNCHER} and
262  *         {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components
263  *         with an intent that lists <em>both</em> of those categories.
264  *         Activities will very often need to support the
265  *         {@link #CATEGORY_DEFAULT} so that they can be found by
266  *         {@link Context#startActivity Context.startActivity()}.</p>
267  * </ul>
268  *
269  * <p>For example, consider the Note Pad sample application that
270  * allows a user to browse through a list of notes data and view details about
271  * individual items.  Text in italics indicates places where you would replace a
272  * name with one specific to your own package.</p>
273  *

326  *         &lt;/activity&gt;
327  *
328  *     &lt;/application&gt;
329  * &lt;/manifest&gt;</pre>
330  *
331  * <p>The first activity,
332  * <code>com.android.notepad.NotesList</code>, serves as our main
333  * entry into the app.  It can do three things as described by its three intent
334  * templates:
335  * <ol>
336  * <li><pre>
337  * &lt;intent-filter&gt;
338  *     &lt;action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /&gt;
339  *     &lt;category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /&gt;
340  * &lt;/intent-filter&gt;</pre>
341  * <p>This provides a top-level entry into the NotePad application: the standard
342  * MAIN action is a main entry point (not requiring any other information in
343  * the Intent), and the LAUNCHER category says that this entry point should be
344  * listed in the application launcher.</p>
345  * <li><pre>
346  * &lt;intent-filter&gt;
347  *     &lt;action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /&gt;
348  *     &lt;action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /&gt;
349  *     &lt;action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /&gt;
350  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
351  *     &lt;data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /&gt;
352  * &lt;/intent-filter&gt;</pre>
353  * <p>This declares the things that the activity can do on a directory of
354  * notes.  The type being supported is given with the &lt;type&gt; tag, where
355  * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which
356  * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can
357  * be retrieved which holds our note pad data (<code>vnd.google.note</code>).
358  * The activity allows the user to view or edit the directory of data (via
359  * the VIEW and EDIT actions), or to pick a particular note and return it
360  * to the caller (via the PICK action).  Note also the DEFAULT category
361  * supplied here: this is <em>required</em> for the
362  * {@link Context#startActivity Context.startActivity} method to resolve your
363  * activity when its component name is not explicitly specified.</p>
364  * <li><pre>
365  * &lt;intent-filter&gt;
366  *     &lt;action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /&gt;
367  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
368  *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
369  * &lt;/intent-filter&gt;</pre>
370  * <p>This filter describes the ability to return to the caller a note selected by
371  * the user without needing to know where it came from.  The data type
372  * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which
373  * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can
374  * be retrieved which contains our note pad data (<code>vnd.google.note</code>).
375  * The GET_CONTENT action is similar to the PICK action, where the activity
376  * will return to its caller a piece of data selected by the user.  Here,
377  * however, the caller specifies the type of data they desire instead of
378  * the type of data the user will be picking from.</p>
379  * </ol>
380  *
381  * <p>Given these capabilities, the following intents will resolve to the
382  * NotesList activity:</p>
383  *
384  * <ul>
385  *     <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the
386  *         activities that can be used as top-level entry points into an
387  *         application.</p>
388  *     <li> <p><b>{ action=android.app.action.MAIN,
389  *         category=android.app.category.LAUNCHER }</b> is the actual intent
390  *         used by the Launcher to populate its top-level list.</p>
391  *     <li> <p><b>{ action=android.intent.action.VIEW
392  *          data=content://com.google.provider.NotePad/notes }</b>
393  *         displays a list of all the notes under
394  *         "content://com.google.provider.NotePad/notes", which
395  *         the user can browse through and see the details on.</p>
396  *     <li> <p><b>{ action=android.app.action.PICK
397  *          data=content://com.google.provider.NotePad/notes }</b>
398  *         provides a list of the notes under
399  *         "content://com.google.provider.NotePad/notes", from which
400  *         the user can pick a note whose data URL is returned back to the caller.</p>
401  *     <li> <p><b>{ action=android.app.action.GET_CONTENT
402  *          type=vnd.android.cursor.item/vnd.google.note }</b>
403  *         is similar to the pick action, but allows the caller to specify the
404  *         kind of data they want back so that the system can find the appropriate
405  *         activity to pick something of that data type.</p>
406  * </ul>
407  *
408  * <p>The second activity,
409  * <code>com.android.notepad.NoteEditor</code>, shows the user a single
410  * note entry and allows them to edit it.  It can do two things as described
411  * by its two intent templates:
412  * <ol>
413  * <li><pre>
414  * &lt;intent-filter android:label="@string/resolve_edit"&gt;
415  *     &lt;action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /&gt;
416  *     &lt;action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /&gt;
417  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
418  *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
419  * &lt;/intent-filter&gt;</pre>
420  * <p>The first, primary, purpose of this activity is to let the user interact
421  * with a single note, as decribed by the MIME type
422  * <code>vnd.android.cursor.item/vnd.google.note</code>.  The activity can
423  * either VIEW a note or allow the user to EDIT it.  Again we support the
424  * DEFAULT category to allow the activity to be launched without explicitly
425  * specifying its component.</p>
426  * <li><pre>
427  * &lt;intent-filter&gt;
428  *     &lt;action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /&gt;
429  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
430  *     &lt;data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /&gt;
431  * &lt;/intent-filter&gt;</pre>
432  * <p>The secondary use of this activity is to insert a new note entry into
433  * an existing directory of notes.  This is used when the user creates a new
434  * note: the INSERT action is executed on the directory of notes, causing
435  * this activity to run and have the user create the new note data which
436  * it then adds to the content provider.</p>
437  * </ol>
438  *
439  * <p>Given these capabilities, the following intents will resolve to the
440  * NoteEditor activity:</p>
441  *
442  * <ul>
443  *     <li> <p><b>{ action=android.intent.action.VIEW
444  *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
445  *         shows the user the content of note <var>{ID}</var>.</p>
446  *     <li> <p><b>{ action=android.app.action.EDIT
447  *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
448  *         allows the user to edit the content of note <var>{ID}</var>.</p>
449  *     <li> <p><b>{ action=android.app.action.INSERT
450  *          data=content://com.google.provider.NotePad/notes }</b>
451  *         creates a new, empty note in the notes list at
452  *         "content://com.google.provider.NotePad/notes"
453  *         and allows the user to edit it.  If they keep their changes, the URI
454  *         of the newly created note is returned to the caller.</p>
455  * </ul>
456  *
457  * <p>The last activity,
458  * <code>com.android.notepad.TitleEditor</code>, allows the user to
459  * edit the title of a note.  This could be implemented as a class that the
460  * application directly invokes (by explicitly setting its component in
461  * the Intent), but here we show a way you can publish alternative
462  * operations on existing data:</p>
463  *
464  * <pre>
465  * &lt;intent-filter android:label="@string/resolve_title"&gt;
466  *     &lt;action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /&gt;
467  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
468  *     &lt;category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /&gt;
469  *     &lt;category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /&gt;
470  *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
471  * &lt;/intent-filter&gt;</pre>
472  *
473  * <p>In the single intent template here, we
474  * have created our own private action called
475  * <code>com.android.notepad.action.EDIT_TITLE</code> which means to
476  * edit the title of a note.  It must be invoked on a specific note
477  * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous
478  * view and edit actions, but here displays and edits the title contained
479  * in the note data.
480  *
481  * <p>In addition to supporting the default category as usual, our title editor
482  * also supports two other standard categories: ALTERNATIVE and
483  * SELECTED_ALTERNATIVE.  Implementing
484  * these categories allows others to find the special action it provides
485  * without directly knowing about it, through the
486  * {@link android.content.pm.PackageManager#queryIntentActivityOptions} method, or
487  * more often to build dynamic menu items with
488  * {@link android.view.Menu#addIntentOptions}.  Note that in the intent
489  * template here was also supply an explicit name for the template
490  * (via <code>android:label="@string/resolve_title"</code>) to better control
491  * what the user sees when presented with this activity as an alternative
492  * action to the data they are viewing.
493  *
494  * <p>Given these capabilities, the following intent will resolve to the
495  * TitleEditor activity:</p>
496  *
497  * <ul>
498  *     <li> <p><b>{ action=com.android.notepad.action.EDIT_TITLE
499  *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
500  *         displays and allows the user to edit the title associated
501  *         with note <var>{ID}</var>.</p>
502  * </ul>
503  *
504  * <h3>Standard Activity Actions</h3>
505  *
506  * <p>These are the current standard actions that Intent defines for launching
507  * activities (usually through {@link Context#startActivity}.  The most
508  * important, and by far most frequently used, are {@link #ACTION_MAIN} and
509  * {@link #ACTION_EDIT}.
510  *
511  * <ul>
512  *     <li> {@link #ACTION_MAIN}
513  *     <li> {@link #ACTION_VIEW}
514  *     <li> {@link #ACTION_ATTACH_DATA}

532  * </ul>
533  *
534  * <h3>Standard Broadcast Actions</h3>
535  *
536  * <p>These are the current standard actions that Intent defines for receiving
537  * broadcasts (usually through {@link Context#registerReceiver} or a
538  * &lt;receiver&gt; tag in a manifest).
539  *
540  * <ul>
541  *     <li> {@link #ACTION_TIME_TICK}
542  *     <li> {@link #ACTION_TIME_CHANGED}
543  *     <li> {@link #ACTION_TIMEZONE_CHANGED}
544  *     <li> {@link #ACTION_BOOT_COMPLETED}
545  *     <li> {@link #ACTION_PACKAGE_ADDED}
546  *     <li> {@link #ACTION_PACKAGE_CHANGED}
547  *     <li> {@link #ACTION_PACKAGE_REMOVED}
548  *     <li> {@link #ACTION_PACKAGE_RESTARTED}
549  *     <li> {@link #ACTION_PACKAGE_DATA_CLEARED}
550  *     <li> {@link #ACTION_PACKAGES_SUSPENDED}
551  *     <li> {@link #ACTION_PACKAGES_UNSUSPENDED}
552  *     <li> {@link #ACTION_UID_REMOVED}
553  *     <li> {@link #ACTION_BATTERY_CHANGED}
554  *     <li> {@link #ACTION_POWER_CONNECTED}
555  *     <li> {@link #ACTION_POWER_DISCONNECTED}
556  *     <li> {@link #ACTION_SHUTDOWN}
557  * </ul>
558  *
559  * <h3>Standard Categories</h3>
560  *
561  * <p>These are the current standard categories that can be used to further
562  * clarify an Intent via {@link #addCategory}.
563  *
564  * <ul>
565  *     <li> {@link #CATEGORY_DEFAULT}
566  *     <li> {@link #CATEGORY_BROWSABLE}
567  *     <li> {@link #CATEGORY_TAB}
568  *     <li> {@link #CATEGORY_ALTERNATIVE}
569  *     <li> {@link #CATEGORY_SELECTED_ALTERNATIVE}
570  *     <li> {@link #CATEGORY_LAUNCHER}
571  *     <li> {@link #CATEGORY_INFO}

897      * always be shown even if one of them is currently marked as the
898      * preferred activity.
899      * </ul>
900      * <p>

902      * select an activity in order to proceed.  An example if when not to use

904      * expect to go directly to their mail app, so startActivity() should be

906      * either launch the current preferred app, or put up a dialog allowing the
907      * user to pick an app to use and optionally marking that as preferred.
908      * <p>
909      * In contrast, if the user is selecting a menu item to send a picture
910      * they are viewing to someone else, there are many different things they
911      * may want to do at this point: send it through e-mail, upload it to a
912      * web service, etc.  In this case the CHOOSER action should be used, to
913      * always present to the user a list of the things they can do, with a

917      * the permissions to be granted on the ACTION_CHOOSER Intent

1021      * just say what kind of data is desired, not a URI of existing data from

1024      * sound), let them browse over the web and download the desired data,
1025      * etc.
1026      * <p>
1027      * There are two main ways to use this action: if you want a specific kind
1028      * of data, such as a person contact, you set the MIME type to the kind of
1029      * data you want and launch it with {@link Context#startActivity(Intent)}.
1030      * The system will then launch the best application to select that kind
1031      * of data for you.
1032      * <p>
1033      * You may also be interested in any of a set of types of content the user
1034      * can pick.  For example, an e-mail application that wants to allow the
1035      * user to add an attachment to an e-mail message can use this action to
1036      * bring up a list of all of the types of content the user can attach.
1037      * <p>
1038      * In this case, you should wrap the GET_CONTENT intent with a chooser
1039      * (through {@link #createChooser}), which will give the proper interface
1040      * for the user to pick how to send your data and allow you to specify
1041      * a prompt indicating what they are doing.  You will usually specify a
1042      * broad MIME type (such as image/* or {@literal *}/*), resulting in a
1043      * broad range of content types the user can select from.
1044      * <p>
1045      * When using such a broad GET_CONTENT action, it is often desirable to
1046      * only pick from data that can be represented as a stream.  This is
1047      * accomplished by requiring the {@link #CATEGORY_OPENABLE} in the Intent.
1048      * <p>
1049      * Callers can optionally specify {@link #EXTRA_LOCAL_ONLY} to request that
1050      * the launched content chooser only returns results representing data that
1051      * is locally available on the device.  For example, if this extra is set
1052      * to true then an image picker should not show any pictures that are available
1053      * from a remote server but not already on the local device (thus requiring
1054      * they be downloaded when opened).
1055      * <p>
1056      * If the caller can handle multiple returned items (the user performing
1057      * multiple selection), then it can specify {@link #EXTRA_ALLOW_MULTIPLE}
1058      * to indicate this.
1059      * <p>
1060      * Input: {@link #getType} is the desired MIME type to retrieve.  Note
1061      * that no URI is supplied in the intent, as there are no constraints on
1062      * where the returned data originally comes from.  You may also include the
1063      * {@link #CATEGORY_OPENABLE} if you can only accept data that can be
1064      * opened as a stream.  You may use {@link #EXTRA_LOCAL_ONLY} to limit content
1065      * selection to local data.  You may use {@link #EXTRA_ALLOW_MULTIPLE} to
1066      * allow the user to select multiple items.

5599      * {@link android.R.attr#documentLaunchMode}, is
5600      * preferred over the Intent flag described here. The attribute form allows the
5601      * Activity to specify multiple document behavior for all launchers of the Activity
5602      * whereas using this flag requires each Intent that launches the Activity to specify it.
5603      *
5604      * <p>Note that the default semantics of this flag w.r.t. whether the recents entry for
5605      * it is kept after the activity is finished is different than the use of
5606      * {@link #FLAG_ACTIVITY_NEW_TASK} and {@link android.R.attr#documentLaunchMode} -- if
5607      * this flag is being used to create a new recents entry, then by default that entry
5608      * will be removed once the activity is finished.  You can modify this behavior with
5609      * {@link #FLAG_ACTIVITY_RETAIN_IN_RECENTS}.
5610      *
5611      * <p>FLAG_ACTIVITY_NEW_DOCUMENT may be used in conjunction with {@link

5615      * FLAG_ACTIVITY_MULTIPLE_TASK it is the equivalent of the Activity manifest specifying
