53/**
54 * An intent is an abstract description of an operation to be performed.  It
55 * can be used with {@link Context#startActivity(Intent) startActivity} to
56 * launch an {@link android.app.Activity},
57 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to
58 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components,
59 * and {@link android.content.Context#startService} or
60 * {@link android.content.Context#bindService} to communicate with a
61 * background {@link android.app.Service}.
62 *
63 * <p>An Intent provides a facility for performing late runtime binding between the code in
64 * different applications. Its most significant use is in the launching of activities, where it
65 * can be thought of as the glue between activities. It is basically a passive data structure
66 * holding an abstract description of an action to be performed.</p>
67 *
68 * <div class="special reference">
69 * <h3>Developer Guides</h3>
70 * <p>For information about how to create and resolve intents, read the
71 * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a>
72 * developer guide.</p>
73 * </div>
74 *
75 * <a name="IntentStructure"></a>
76 * <h3>Intent Structure</h3>
77 * <p>The primary pieces of information in an intent are:</p>
78 *
79 * <ul>
80 *   <li> <p><b>action</b> -- The general action to be performed, such as
81 *     {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN},
82 *     etc.</p>
83 *   </li>
84 *   <li> <p><b>data</b> -- The data to operate on, such as a person record
85 *     in the contacts database, expressed as a {@link android.net.Uri}.</p>
86 *   </li>
87 * </ul>
88 *
89 *
90 * <p>Some examples of action/data pairs are:</p>
91 *
92 * <ul>
93 *   <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display
94 *     information about the person whose identifier is "1".</p>
95 *   </li>
96 *   <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display
97 *     the phone dialer with the person filled in.</p>
98 *   </li>
99 *   <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display
100 *     the phone dialer with the given number filled in.  Note how the
101 *     VIEW action does what what is considered the most reasonable thing for
102 *     a particular URI.</p>
103 *   </li>
104 *   <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display
105 *     the phone dialer with the given number filled in.</p>
106 *   </li>
107 *   <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit
108 *     information about the person whose identifier is "1".</p>
109 *   </li>
110 *   <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display
111 *     a list of people, which the user can browse through.  This example is a
112 *     typical top-level entry into the Contacts application, showing you the
113 *     list of people. Selecting a particular person to view would result in a
114 *     new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> }
115 *     being used to start an activity to display that person.</p>
116 *   </li>
117 * </ul>
118 *
119 * <p>In addition to these primary attributes, there are a number of secondary
120 * attributes that you can also include with an intent:</p>
121 *
122 * <ul>
123 *     <li> <p><b>category</b> -- Gives additional information about the action
124 *         to execute.  For example, {@link #CATEGORY_LAUNCHER} means it should
125 *         appear in the Launcher as a top-level application, while
126 *         {@link #CATEGORY_ALTERNATIVE} means it should be included in a list
127 *         of alternative actions the user can perform on a piece of data.</p>
128 *     <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the
129 *         intent data.  Normally the type is inferred from the data itself.
130 *         By setting this attribute, you disable that evaluation and force
131 *         an explicit type.</p>
132 *     <li> <p><b>component</b> -- Specifies an explicit name of a component
133 *         class to use for the intent.  Normally this is determined by looking
134 *         at the other information in the intent (the action, data/type, and
135 *         categories) and matching that with a component that can handle it.
136 *         If this attribute is set then none of the evaluation is performed,
137 *         and this component is used exactly as is.  By specifying this attribute,
138 *         all of the other Intent attributes become optional.</p>
139 *     <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information.
140 *         This can be used to provide extended information to the component.
141 *         For example, if we have a action to send an e-mail message, we could
142 *         also include extra pieces of data here to supply a subject, body,
143 *         etc.</p>
144 * </ul>
145 *
146 * <p>Here are some examples of other operations you can specify as intents
147 * using these additional parameters:</p>
148 *
149 * <ul>
150 *   <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> --
151 *     Launch the home screen.</p>
152 *   </li>
153 *   <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type
154 *     <i>{@link android.provider.Contacts.Phones#CONTENT_URI
155 *     vnd.android.cursor.item/phone}</i></b>
156 *     -- Display the list of people's phone numbers, allowing the user to
157 *     browse through them and pick one and return it to the parent activity.</p>
158 *   </li>
159 *   <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type
160 *     <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b>
161 *     -- Display all pickers for data that can be opened with
162 *     {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()},
163 *     allowing the user to pick one of them and then some data inside of it
164 *     and returning the resulting URI to the caller.  This can be used,
165 *     for example, in an e-mail application to allow the user to pick some
166 *     data to include as an attachment.</p>
167 *   </li>
168 * </ul>
169 *
170 * <p>There are a variety of standard Intent action and category constants
171 * defined in the Intent class, but applications can also define their own.
172 * These strings use java style scoping, to ensure they are unique -- for
173 * example, the standard {@link #ACTION_VIEW} is called
174 * "android.intent.action.VIEW".</p>
175 *
176 * <p>Put together, the set of actions, data types, categories, and extra data
177 * defines a language for the system allowing for the expression of phrases
178 * such as "call john smith's cell".  As applications are added to the system,
179 * they can extend this language by adding new actions, types, and categories, or
180 * they can modify the behavior of existing phrases by supplying their own
181 * activities that handle them.</p>
182 *
183 * <a name="IntentResolution"></a>
184 * <h3>Intent Resolution</h3>
185 *
186 * <p>There are two primary forms of intents you will use.
187 *
188 * <ul>
189 *     <li> <p><b>Explicit Intents</b> have specified a component (via
190 *     {@link #setComponent} or {@link #setClass}), which provides the exact
191 *     class to be run.  Often these will not include any other information,
192 *     simply being a way for an application to launch various internal
193 *     activities it has as the user interacts with the application.
194 *
195 *     <li> <p><b>Implicit Intents</b> have not specified a component;
196 *     instead, they must include enough information for the system to
197 *     determine which of the available components is best to run for that
198 *     intent.
199 * </ul>
200 *
201 * <p>When using implicit intents, given such an arbitrary intent we need to
202 * know what to do with it. This is handled by the process of <em>Intent
203 * resolution</em>, which maps an Intent to an {@link android.app.Activity},
204 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or
205 * more activities/receivers) that can handle it.</p>
206 *
207 * <p>The intent resolution mechanism basically revolves around matching an
208 * Intent against all of the &lt;intent-filter&gt; descriptions in the
209 * installed application packages.  (Plus, in the case of broadcasts, any {@link BroadcastReceiver}
210 * objects explicitly registered with {@link Context#registerReceiver}.)  More
211 * details on this can be found in the documentation on the {@link
212 * IntentFilter} class.</p>
213 *
214 * <p>There are three pieces of information in the Intent that are used for
215 * resolution: the action, type, and category.  Using this information, a query
216 * is done on the {@link PackageManager} for a component that can handle the
217 * intent. The appropriate component is determined based on the intent
218 * information supplied in the <code>AndroidManifest.xml</code> file as
219 * follows:</p>
220 *
221 * <ul>
222 *     <li> <p>The <b>action</b>, if given, must be listed by the component as
223 *         one it handles.</p>
224 *     <li> <p>The <b>type</b> is retrieved from the Intent's data, if not
225 *         already supplied in the Intent.  Like the action, if a type is
226 *         included in the intent (either explicitly or implicitly in its
227 *         data), then this must be listed by the component as one it handles.</p>
228 *     <li> For data that is not a <code>content:</code> URI and where no explicit
229 *         type is included in the Intent, instead the <b>scheme</b> of the
230 *         intent data (such as <code>http:</code> or <code>mailto:</code>) is
231 *         considered. Again like the action, if we are matching a scheme it
232 *         must be listed by the component as one it can handle.
233 *     <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed
234 *         by the activity as categories it handles.  That is, if you include
235 *         the categories {@link #CATEGORY_LAUNCHER} and
236 *         {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components
237 *         with an intent that lists <em>both</em> of those categories.
238 *         Activities will very often need to support the
239 *         {@link #CATEGORY_DEFAULT} so that they can be found by
240 *         {@link Context#startActivity Context.startActivity()}.</p>
241 * </ul>
242 *
243 * <p>For example, consider the Note Pad sample application that
244 * allows user to browse through a list of notes data and view details about
245 * individual items.  Text in italics indicate places were you would replace a
246 * name with one specific to your own package.</p>
247 *

292 *                 android:theme="@android:style/Theme.Dialog"&gt;

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

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

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

513 *
514 * <ul>
515 *     <li> {@link #ACTION_TIME_TICK}

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

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

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