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>
244 *

287 *
288 *         &lt;activity class=".TitleEditor" android:label="@string/title_edit_title"
289 *                 android:theme="@android:style/Theme.Dialog"&gt;
290 *             &lt;intent-filter android:label="@string/resolve_title"&gt;

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

296 *             &lt;/intent-filter&gt;
297 *         &lt;/activity&gt;
298 *
299 *     &lt;/application&gt;
300 * &lt;/manifest&gt;</pre>
301 *
302 * <p>The first activity,
303 * <code>com.android.notepad.NotesList</code>, serves as our main
304 * entry into the app.  It can do three things as described by its three intent
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;
321 *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&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}

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

510 *
511 * <ul>
512 *     <li> {@link #ACTION_TIME_TICK}

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}

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

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