55 * An intent is an abstract description of an operation to be performed.  It
56 * can be used with {@link Context#startActivity(Intent) startActivity} to
57 * launch an {@link android.app.Activity},
58 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to
59 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components,
60 * and {@link android.content.Context#startService} or
61 * {@link android.content.Context#bindService} to communicate with a
62 * background {@link android.app.Service}.
63 *
64 * <p>An Intent provides a facility for performing late runtime binding between the code in
65 * different applications. Its most significant use is in the launching of activities, where it
66 * can be thought of as the glue between activities. It is basically a passive data structure
67 * holding an abstract description of an action to be performed.</p>
68 *
69 * <div class="special reference">
70 * <h3>Developer Guides</h3>
71 * <p>For information about how to create and resolve intents, read the
72 * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a>
73 * developer guide.</p>
74 * </div>
75 *
76 * <a name="IntentStructure"></a>
77 * <h3>Intent Structure</h3>
78 * <p>The primary pieces of information in an intent are:</p>
79 *
80 * <ul>
81 *   <li> <p><b>action</b> -- The general action to be performed, such as
82 *     {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN},
83 *     etc.</p>
84 *   </li>
85 *   <li> <p><b>data</b> -- The data to operate on, such as a person record
86 *     in the contacts database, expressed as a {@link android.net.Uri}.</p>
87 *   </li>
88 * </ul>
89 *
90 *
91 * <p>Some examples of action/data pairs are:</p>
92 *
93 * <ul>
94 *   <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display
95 *     information about the person whose identifier is "1".</p>
96 *   </li>
97 *   <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display
98 *     the phone dialer with the person filled in.</p>
99 *   </li>
100 *   <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display
101 *     the phone dialer with the given number filled in.  Note how the
102 *     VIEW action does what what is considered the most reasonable thing for
103 *     a particular URI.</p>
104 *   </li>
105 *   <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display
106 *     the phone dialer with the given number filled in.</p>
107 *   </li>
108 *   <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit
109 *     information about the person whose identifier is "1".</p>
110 *   </li>
111 *   <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display
112 *     a list of people, which the user can browse through.  This example is a
113 *     typical top-level entry into the Contacts application, showing you the
114 *     list of people. Selecting a particular person to view would result in a
115 *     new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> }
116 *     being used to start an activity to display that person.</p>
117 *   </li>
118 * </ul>
119 *
120 * <p>In addition to these primary attributes, there are a number of secondary
121 * attributes that you can also include with an intent:</p>
122 *
123 * <ul>
124 *     <li> <p><b>category</b> -- Gives additional information about the action
125 *         to execute.  For example, {@link #CATEGORY_LAUNCHER} means it should
126 *         appear in the Launcher as a top-level application, while
127 *         {@link #CATEGORY_ALTERNATIVE} means it should be included in a list
128 *         of alternative actions the user can perform on a piece of data.</p>
129 *     <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the
130 *         intent data.  Normally the type is inferred from the data itself.
131 *         By setting this attribute, you disable that evaluation and force
132 *         an explicit type.</p>
133 *     <li> <p><b>component</b> -- Specifies an explicit name of a component
134 *         class to use for the intent.  Normally this is determined by looking
135 *         at the other information in the intent (the action, data/type, and
136 *         categories) and matching that with a component that can handle it.
137 *         If this attribute is set then none of the evaluation is performed,
138 *         and this component is used exactly as is.  By specifying this attribute,
139 *         all of the other Intent attributes become optional.</p>
140 *     <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information.
141 *         This can be used to provide extended information to the component.
142 *         For example, if we have a action to send an e-mail message, we could
143 *         also include extra pieces of data here to supply a subject, body,
144 *         etc.</p>
145 * </ul>
146 *
147 * <p>Here are some examples of other operations you can specify as intents
148 * using these additional parameters:</p>
149 *
150 * <ul>
151 *   <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> --
152 *     Launch the home screen.</p>
153 *   </li>
154 *   <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type
155 *     <i>{@link android.provider.Contacts.Phones#CONTENT_URI
156 *     vnd.android.cursor.item/phone}</i></b>
157 *     -- Display the list of people's phone numbers, allowing the user to
158 *     browse through them and pick one and return it to the parent activity.</p>
159 *   </li>
160 *   <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type
161 *     <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b>
162 *     -- Display all pickers for data that can be opened with
163 *     {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()},
164 *     allowing the user to pick one of them and then some data inside of it
165 *     and returning the resulting URI to the caller.  This can be used,
166 *     for example, in an e-mail application to allow the user to pick some
167 *     data to include as an attachment.</p>
168 *   </li>
169 * </ul>
170 *
171 * <p>There are a variety of standard Intent action and category constants
172 * defined in the Intent class, but applications can also define their own.
173 * These strings use java style scoping, to ensure they are unique -- for
174 * example, the standard {@link #ACTION_VIEW} is called
175 * "android.intent.action.VIEW".</p>
176 *
177 * <p>Put together, the set of actions, data types, categories, and extra data
178 * defines a language for the system allowing for the expression of phrases
179 * such as "call john smith's cell".  As applications are added to the system,
180 * they can extend this language by adding new actions, types, and categories, or
181 * they can modify the behavior of existing phrases by supplying their own
182 * activities that handle them.</p>
183 *
184 * <a name="IntentResolution"></a>
185 * <h3>Intent Resolution</h3>
186 *
187 * <p>There are two primary forms of intents you will use.
188 *
189 * <ul>
190 *     <li> <p><b>Explicit Intents</b> have specified a component (via
191 *     {@link #setComponent} or {@link #setClass}), which provides the exact
192 *     class to be run.  Often these will not include any other information,
193 *     simply being a way for an application to launch various internal
194 *     activities it has as the user interacts with the application.
195 *
196 *     <li> <p><b>Implicit Intents</b> have not specified a component;
197 *     instead, they must include enough information for the system to
198 *     determine which of the available components is best to run for that
199 *     intent.
200 * </ul>
201 *
202 * <p>When using implicit intents, given such an arbitrary intent we need to
203 * know what to do with it. This is handled by the process of <em>Intent
204 * resolution</em>, which maps an Intent to an {@link android.app.Activity},
205 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or
206 * more activities/receivers) that can handle it.</p>
207 *
208 * <p>The intent resolution mechanism basically revolves around matching an
209 * Intent against all of the &lt;intent-filter&gt; descriptions in the
210 * installed application packages.  (Plus, in the case of broadcasts, any {@link BroadcastReceiver}
211 * objects explicitly registered with {@link Context#registerReceiver}.)  More
212 * details on this can be found in the documentation on the {@link
213 * IntentFilter} class.</p>
214 *
215 * <p>There are three pieces of information in the Intent that are used for
216 * resolution: the action, type, and category.  Using this information, a query
217 * is done on the {@link PackageManager} for a component that can handle the
218 * intent. The appropriate component is determined based on the intent
219 * information supplied in the <code>AndroidManifest.xml</code> file as
220 * follows:</p>
221 *
222 * <ul>
223 *     <li> <p>The <b>action</b>, if given, must be listed by the component as
224 *         one it handles.</p>
225 *     <li> <p>The <b>type</b> is retrieved from the Intent's data, if not
226 *         already supplied in the Intent.  Like the action, if a type is
227 *         included in the intent (either explicitly or implicitly in its
228 *         data), then this must be listed by the component as one it handles.</p>
229 *     <li> For data that is not a <code>content:</code> URI and where no explicit
230 *         type is included in the Intent, instead the <b>scheme</b> of the
231 *         intent data (such as <code>http:</code> or <code>mailto:</code>) is
232 *         considered. Again like the action, if we are matching a scheme it
233 *         must be listed by the component as one it can handle.
234 *     <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed
235 *         by the activity as categories it handles.  That is, if you include
236 *         the categories {@link #CATEGORY_LAUNCHER} and
237 *         {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components
238 *         with an intent that lists <em>both</em> of those categories.
239 *         Activities will very often need to support the
240 *         {@link #CATEGORY_DEFAULT} so that they can be found by
241 *         {@link Context#startActivity Context.startActivity()}.</p>
242 * </ul>
243 *
244 * <p>For example, consider the Note Pad sample application that
245 * allows user to browse through a list of notes data and view details about
246 * individual items.  Text in italics indicate places were you would replace a
247 * name with one specific to your own package.</p>
248 *

291 *
292 *         &lt;activity class=".TitleEditor" android:label="@string/title_edit_title"
293 *                 android:theme="@android:style/Theme.Dialog"&gt;

298 *                 &lt;category android:name="android.intent.category.SELECTED_ALTERNATIVE" /&gt;

300 *             &lt;/intent-filter&gt;
301 *         &lt;/activity&gt;
302 *
303 *     &lt;/application&gt;
304 * &lt;/manifest&gt;</pre>
305 *
306 * <p>The first activity,
307 * <code>com.android.notepad.NotesList</code>, serves as our main
308 * entry into the app.  It can do three things as described by its three intent
309 * templates:
310 * <ol>
311 * <li><pre>
312 * &lt;intent-filter&gt;
313 *     &lt;action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /&gt;
314 *     &lt;category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /&gt;
315 * &lt;/intent-filter&gt;</pre>
316 * <p>This provides a top-level entry into the NotePad application: the standard
317 * MAIN action is a main entry point (not requiring any other information in
318 * the Intent), and the LAUNCHER category says that this entry point should be
319 * listed in the application launcher.</p>
320 * <li><pre>
321 * &lt;intent-filter&gt;
322 *     &lt;action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /&gt;
323 *     &lt;action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /&gt;
324 *     &lt;action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /&gt;
325 *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
326 *     &lt;data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /&gt;
327 * &lt;/intent-filter&gt;</pre>
328 * <p>This declares the things that the activity can do on a directory of
329 * notes.  The type being supported is given with the &lt;type&gt; tag, where
330 * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which
331 * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can
332 * be retrieved which holds our note pad data (<code>vnd.google.note</code>).
333 * The activity allows the user to view or edit the directory of data (via
334 * the VIEW and EDIT actions), or to pick a particular note and return it
335 * to the caller (via the PICK action).  Note also the DEFAULT category
336 * supplied here: this is <em>required</em> for the
337 * {@link Context#startActivity Context.startActivity} method to resolve your
338 * activity when its component name is not explicitly specified.</p>
339 * <li><pre>
340 * &lt;intent-filter&gt;
341 *     &lt;action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /&gt;
342 *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
343 *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
344 * &lt;/intent-filter&gt;</pre>
345 * <p>This filter describes the ability return to the caller a note selected by
346 * the user without needing to know where it came from.  The data type
347 * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which
348 * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can
349 * be retrieved which contains our note pad data (<code>vnd.google.note</code>).
350 * The GET_CONTENT action is similar to the PICK action, where the activity
351 * will return to its caller a piece of data selected by the user.  Here,
352 * however, the caller specifies the type of data they desire instead of
353 * the type of data the user will be picking from.</p>
354 * </ol>
355 *
356 * <p>Given these capabilities, the following intents will resolve to the
357 * NotesList activity:</p>
358 *
359 * <ul>
360 *     <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the
361 *         activities that can be used as top-level entry points into an
362 *         application.</p>
363 *     <li> <p><b>{ action=android.app.action.MAIN,
364 *         category=android.app.category.LAUNCHER }</b> is the actual intent
365 *         used by the Launcher to populate its top-level list.</p>
366 *     <li> <p><b>{ action=android.intent.action.VIEW
367 *          data=content://com.google.provider.NotePad/notes }</b>
368 *         displays a list of all the notes under
369 *         "content://com.google.provider.NotePad/notes", which
370 *         the user can browse through and see the details on.</p>
371 *     <li> <p><b>{ action=android.app.action.PICK
372 *          data=content://com.google.provider.NotePad/notes }</b>
373 *         provides a list of the notes under
374 *         "content://com.google.provider.NotePad/notes", from which
375 *         the user can pick a note whose data URL is returned back to the caller.</p>
376 *     <li> <p><b>{ action=android.app.action.GET_CONTENT
377 *          type=vnd.android.cursor.item/vnd.google.note }</b>
378 *         is similar to the pick action, but allows the caller to specify the
379 *         kind of data they want back so that the system can find the appropriate
380 *         activity to pick something of that data type.</p>
381 * </ul>
382 *
383 * <p>The second activity,
384 * <code>com.android.notepad.NoteEditor</code>, shows the user a single
385 * note entry and allows them to edit it.  It can do two things as described
386 * by its two intent templates:
387 * <ol>
388 * <li><pre>
389 * &lt;intent-filter android:label="@string/resolve_edit"&gt;
390 *     &lt;action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /&gt;
391 *     &lt;action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /&gt;
392 *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
393 *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
394 * &lt;/intent-filter&gt;</pre>
395 * <p>The first, primary, purpose of this activity is to let the user interact
396 * with a single note, as decribed by the MIME type
397 * <code>vnd.android.cursor.item/vnd.google.note</code>.  The activity can
398 * either VIEW a note or allow the user to EDIT it.  Again we support the
399 * DEFAULT category to allow the activity to be launched without explicitly
400 * specifying its component.</p>
401 * <li><pre>
402 * &lt;intent-filter&gt;
403 *     &lt;action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /&gt;
404 *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
405 *     &lt;data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /&gt;
406 * &lt;/intent-filter&gt;</pre>
407 * <p>The secondary use of this activity is to insert a new note entry into
408 * an existing directory of notes.  This is used when the user creates a new
409 * note: the INSERT action is executed on the directory of notes, causing
410 * this activity to run and have the user create the new note data which
411 * it then adds to the content provider.</p>
412 * </ol>
413 *
414 * <p>Given these capabilities, the following intents will resolve to the
415 * NoteEditor activity:</p>
416 *
417 * <ul>
418 *     <li> <p><b>{ action=android.intent.action.VIEW
419 *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
420 *         shows the user the content of note <var>{ID}</var>.</p>
421 *     <li> <p><b>{ action=android.app.action.EDIT
422 *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
423 *         allows the user to edit the content of note <var>{ID}</var>.</p>
424 *     <li> <p><b>{ action=android.app.action.INSERT
425 *          data=content://com.google.provider.NotePad/notes }</b>
426 *         creates a new, empty note in the notes list at
427 *         "content://com.google.provider.NotePad/notes"
428 *         and allows the user to edit it.  If they keep their changes, the URI
429 *         of the newly created note is returned to the caller.</p>
430 * </ul>
431 *
432 * <p>The last activity,
433 * <code>com.android.notepad.TitleEditor</code>, allows the user to
434 * edit the title of a note.  This could be implemented as a class that the
435 * application directly invokes (by explicitly setting its component in
436 * the Intent), but here we show a way you can publish alternative
437 * operations on existing data:</p>
438 *
439 * <pre>
440 * &lt;intent-filter android:label="@string/resolve_title"&gt;
441 *     &lt;action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /&gt;
442 *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
443 *     &lt;category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /&gt;
444 *     &lt;category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /&gt;
445 *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
446 * &lt;/intent-filter&gt;</pre>
447 *
448 * <p>In the single intent template here, we
449 * have created our own private action called
450 * <code>com.android.notepad.action.EDIT_TITLE</code> which means to
451 * edit the title of a note.  It must be invoked on a specific note
452 * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous
453 * view and edit actions, but here displays and edits the title contained
454 * in the note data.
455 *
456 * <p>In addition to supporting the default category as usual, our title editor
457 * also supports two other standard categories: ALTERNATIVE and
458 * SELECTED_ALTERNATIVE.  Implementing
459 * these categories allows others to find the special action it provides
460 * without directly knowing about it, through the
461 * {@link android.content.pm.PackageManager#queryIntentActivityOptions} method, or
462 * more often to build dynamic menu items with
463 * {@link android.view.Menu#addIntentOptions}.  Note that in the intent
464 * template here was also supply an explicit name for the template
465 * (via <code>android:label="@string/resolve_title"</code>) to better control
466 * what the user sees when presented with this activity as an alternative
467 * action to the data they are viewing.
468 *
469 * <p>Given these capabilities, the following intent will resolve to the
470 * TitleEditor activity:</p>
471 *
472 * <ul>
473 *     <li> <p><b>{ action=com.android.notepad.action.EDIT_TITLE
474 *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
475 *         displays and allows the user to edit the title associated
476 *         with note <var>{ID}</var>.</p>
477 * </ul>
478 *
479 * <h3>Standard Activity Actions</h3>
480 *
481 * <p>These are the current standard actions that Intent defines for launching
482 * activities (usually through {@link Context#startActivity}.  The most
483 * important, and by far most frequently used, are {@link #ACTION_MAIN} and
484 * {@link #ACTION_EDIT}.
485 *
486 * <ul>
487 *     <li> {@link #ACTION_MAIN}

507 * </ul>
508 *
509 * <h3>Standard Broadcast Actions</h3>
510 *
511 * <p>These are the current standard actions that Intent defines for receiving
512 * broadcasts (usually through {@link Context#registerReceiver} or a

514 *
515 * <ul>
516 *     <li> {@link #ACTION_TIME_TICK}

527 *     <li> {@link #ACTION_POWER_CONNECTED}
528 *     <li> {@link #ACTION_POWER_DISCONNECTED}
529 *     <li> {@link #ACTION_SHUTDOWN}
530 * </ul>
531 *
532 * <h3>Standard Categories</h3>
533 *
534 * <p>These are the current standard categories that can be used to further
535 * clarify an Intent via {@link #addCategory}.
536 *
537 * <ul>
538 *     <li> {@link #CATEGORY_DEFAULT}
539 *     <li> {@link #CATEGORY_BROWSABLE}
540 *     <li> {@link #CATEGORY_TAB}
541 *     <li> {@link #CATEGORY_ALTERNATIVE}
542 *     <li> {@link #CATEGORY_SELECTED_ALTERNATIVE}
543 *     <li> {@link #CATEGORY_LAUNCHER}

790     * Activity Action: Display an activity chooser, allowing the user to pick
791     * what they want to before proceeding.  This can be used as an alternative
792     * to the standard activity picker that is displayed by the system when
793     * you try to start an activity with multiple possible matches, with these
794     * differences in behavior:
795     * <ul>
796     * <li>You can specify the title that will appear in the activity chooser.
797     * <li>The user does not have the option to make one of the matching
798     * activities a preferred activity, and all possible activities will
799     * always be shown even if one of them is currently marked as the
800     * preferred activity.
801     * </ul>
802     * <p>
803     * This action should be used when the user will naturally expect to
804     * select an activity in order to proceed.  An example if when not to use
805     * it is when the user clicks on a "mailto:" link.  They would naturally
806     * expect to go directly to their mail app, so startActivity() should be
807     * called directly: it will
808     * either launch the current preferred app, or put up a dialog allowing the
809     * user to pick an app to use and optionally marking that as preferred.
810     * <p>
811     * In contrast, if the user is selecting a menu item to send a picture
812     * they are viewing to someone else, there are many different things they
813     * may want to do at this point: send it through e-mail, upload it to a
814     * web service, etc.  In this case the CHOOSER action should be used, to
815     * always present to the user a list of the things they can do, with a
816     * nice title given by the caller such as "Send this photo with:".
817     * <p>
818     * If you need to grant URI permissions through a chooser, you must specify
819     * the permissions to be granted on the ACTION_CHOOSER Intent
820     * <em>in addition</em> to the EXTRA_INTENT inside.  This means using
821     * {@link #setClipData} to specify the URIs to be granted as well as
822     * {@link #FLAG_GRANT_READ_URI_PERMISSION} and/or
823     * {@link #FLAG_GRANT_WRITE_URI_PERMISSION} as appropriate.

888     * Activity Action: Allow the user to select a particular kind of data and
889     * return it.  This is different than {@link #ACTION_PICK} in that here we
890     * just say what kind of data is desired, not a URI of existing data from
891     * which the user can pick.  An ACTION_GET_CONTENT could allow the user to
892     * create the data as it runs (for example taking a picture or recording a
893     * sound), let them browse over the web and download the desired data,
894     * etc.
895     * <p>
896     * There are two main ways to use this action: if you want a specific kind
897     * of data, such as a person contact, you set the MIME type to the kind of
898     * data you want and launch it with {@link Context#startActivity(Intent)}.
899     * The system will then launch the best application to select that kind
900     * of data for you.
901     * <p>
902     * You may also be interested in any of a set of types of content the user
903     * can pick.  For example, an e-mail application that wants to allow the
904     * user to add an attachment to an e-mail message can use this action to
905     * bring up a list of all of the types of content the user can attach.
906     * <p>
907     * In this case, you should wrap the GET_CONTENT intent with a chooser
908     * (through {@link #createChooser}), which will give the proper interface
909     * for the user to pick how to send your data and allow you to specify
910     * a prompt indicating what they are doing.  You will usually specify a
911     * broad MIME type (such as image/* or {@literal *}/*), resulting in a
912     * broad range of content types the user can select from.
913     * <p>
914     * When using such a broad GET_CONTENT action, it is often desirable to
915     * only pick from data that can be represented as a stream.  This is
916     * accomplished by requiring the {@link #CATEGORY_OPENABLE} in the Intent.
917     * <p>
918     * Callers can optionally specify {@link #EXTRA_LOCAL_ONLY} to request that
919     * the launched content chooser only returns results representing data that
920     * is locally available on the device.  For example, if this extra is set
921     * to true then an image picker should not show any pictures that are available
922     * from a remote server but not already on the local device (thus requiring
923     * they be downloaded when opened).
924     * <p>
925     * If the caller can handle multiple returned items (the user performing
926     * multiple selection), then it can specify {@link #EXTRA_ALLOW_MULTIPLE}
927     * to indicate this.
928     * <p>
929     * Input: {@link #getType} is the desired MIME type to retrieve.  Note
930     * that no URI is supplied in the intent, as there are no constraints on
931     * where the returned data originally comes from.  You may also include the
932     * {@link #CATEGORY_OPENABLE} if you can only accept data that can be
933     * opened as a stream.  You may use {@link #EXTRA_LOCAL_ONLY} to limit content
934     * selection to local data.  You may use {@link #EXTRA_ALLOW_MULTIPLE} to
935     * allow the user to select multiple items.
936     * <p>
