52/**
53 * An intent is an abstract description of an operation to be performed.  It
54 * can be used with {@link Context#startActivity(Intent) startActivity} to
55 * launch an {@link android.app.Activity},
56 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to
57 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components,
58 * and {@link android.content.Context#startService} or
59 * {@link android.content.Context#bindService} to communicate with a
60 * background {@link android.app.Service}.
61 *
62 * <p>An Intent provides a facility for performing late runtime binding between the code in
63 * different applications. Its most significant use is in the launching of activities, where it
64 * can be thought of as the glue between activities. It is basically a passive data structure
65 * holding an abstract description of an action to be performed.</p>
66 *
67 * <div class="special reference">
68 * <h3>Developer Guides</h3>
69 * <p>For information about how to create and resolve intents, read the
70 * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a>
71 * developer guide.</p>
72 * </div>
73 *
74 * <a name="IntentStructure"></a>
75 * <h3>Intent Structure</h3>
76 * <p>The primary pieces of information in an intent are:</p>
77 *
78 * <ul>
79 *   <li> <p><b>action</b> -- The general action to be performed, such as
80 *     {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN},
81 *     etc.</p>
82 *   </li>
83 *   <li> <p><b>data</b> -- The data to operate on, such as a person record
84 *     in the contacts database, expressed as a {@link android.net.Uri}.</p>
85 *   </li>
86 * </ul>
87 *
88 *
89 * <p>Some examples of action/data pairs are:</p>
90 *
91 * <ul>
92 *   <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display
93 *     information about the person whose identifier is "1".</p>
94 *   </li>
95 *   <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display
96 *     the phone dialer with the person filled in.</p>
97 *   </li>
98 *   <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display
99 *     the phone dialer with the given number filled in.  Note how the
100 *     VIEW action does what what is considered the most reasonable thing for
101 *     a particular URI.</p>
102 *   </li>
103 *   <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display
104 *     the phone dialer with the given number filled in.</p>
105 *   </li>
106 *   <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit
107 *     information about the person whose identifier is "1".</p>
108 *   </li>
109 *   <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display
110 *     a list of people, which the user can browse through.  This example is a
111 *     typical top-level entry into the Contacts application, showing you the
112 *     list of people. Selecting a particular person to view would result in a
113 *     new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> }
114 *     being used to start an activity to display that person.</p>
115 *   </li>
116 * </ul>
117 *
118 * <p>In addition to these primary attributes, there are a number of secondary
119 * attributes that you can also include with an intent:</p>
120 *
121 * <ul>
122 *     <li> <p><b>category</b> -- Gives additional information about the action
123 *         to execute.  For example, {@link #CATEGORY_LAUNCHER} means it should
124 *         appear in the Launcher as a top-level application, while
125 *         {@link #CATEGORY_ALTERNATIVE} means it should be included in a list
126 *         of alternative actions the user can perform on a piece of data.</p>
127 *     <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the
128 *         intent data.  Normally the type is inferred from the data itself.
129 *         By setting this attribute, you disable that evaluation and force
130 *         an explicit type.</p>
131 *     <li> <p><b>component</b> -- Specifies an explicit name of a component
132 *         class to use for the intent.  Normally this is determined by looking
133 *         at the other information in the intent (the action, data/type, and
134 *         categories) and matching that with a component that can handle it.
135 *         If this attribute is set then none of the evaluation is performed,
136 *         and this component is used exactly as is.  By specifying this attribute,
137 *         all of the other Intent attributes become optional.</p>
138 *     <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information.
139 *         This can be used to provide extended information to the component.
140 *         For example, if we have a action to send an e-mail message, we could
141 *         also include extra pieces of data here to supply a subject, body,
142 *         etc.</p>
143 * </ul>
144 *
145 * <p>Here are some examples of other operations you can specify as intents
146 * using these additional parameters:</p>
147 *
148 * <ul>
149 *   <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> --
150 *     Launch the home screen.</p>
151 *   </li>
152 *   <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type
153 *     <i>{@link android.provider.Contacts.Phones#CONTENT_URI
154 *     vnd.android.cursor.item/phone}</i></b>
155 *     -- Display the list of people's phone numbers, allowing the user to
156 *     browse through them and pick one and return it to the parent activity.</p>
157 *   </li>
158 *   <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type
159 *     <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b>
160 *     -- Display all pickers for data that can be opened with
161 *     {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()},
162 *     allowing the user to pick one of them and then some data inside of it
163 *     and returning the resulting URI to the caller.  This can be used,
164 *     for example, in an e-mail application to allow the user to pick some
165 *     data to include as an attachment.</p>
166 *   </li>
167 * </ul>
168 *
169 * <p>There are a variety of standard Intent action and category constants
170 * defined in the Intent class, but applications can also define their own.
171 * These strings use java style scoping, to ensure they are unique -- for
172 * example, the standard {@link #ACTION_VIEW} is called
173 * "android.intent.action.VIEW".</p>
174 *
175 * <p>Put together, the set of actions, data types, categories, and extra data
176 * defines a language for the system allowing for the expression of phrases
177 * such as "call john smith's cell".  As applications are added to the system,
178 * they can extend this language by adding new actions, types, and categories, or
179 * they can modify the behavior of existing phrases by supplying their own
180 * activities that handle them.</p>
181 *
182 * <a name="IntentResolution"></a>
183 * <h3>Intent Resolution</h3>
184 *
185 * <p>There are two primary forms of intents you will use.
186 *
187 * <ul>
188 *     <li> <p><b>Explicit Intents</b> have specified a component (via
189 *     {@link #setComponent} or {@link #setClass}), which provides the exact
190 *     class to be run.  Often these will not include any other information,
191 *     simply being a way for an application to launch various internal
192 *     activities it has as the user interacts with the application.
193 *
194 *     <li> <p><b>Implicit Intents</b> have not specified a component;
195 *     instead, they must include enough information for the system to
196 *     determine which of the available components is best to run for that
197 *     intent.
198 * </ul>
199 *
200 * <p>When using implicit intents, given such an arbitrary intent we need to
201 * know what to do with it. This is handled by the process of <em>Intent
202 * resolution</em>, which maps an Intent to an {@link android.app.Activity},
203 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or
204 * more activities/receivers) that can handle it.</p>
205 *
206 * <p>The intent resolution mechanism basically revolves around matching an
207 * Intent against all of the &lt;intent-filter&gt; descriptions in the
208 * installed application packages.  (Plus, in the case of broadcasts, any {@link BroadcastReceiver}
209 * objects explicitly registered with {@link Context#registerReceiver}.)  More
210 * details on this can be found in the documentation on the {@link
211 * IntentFilter} class.</p>
212 *
213 * <p>There are three pieces of information in the Intent that are used for
214 * resolution: the action, type, and category.  Using this information, a query
215 * is done on the {@link PackageManager} for a component that can handle the
216 * intent. The appropriate component is determined based on the intent
217 * information supplied in the <code>AndroidManifest.xml</code> file as
218 * follows:</p>
219 *
220 * <ul>
221 *     <li> <p>The <b>action</b>, if given, must be listed by the component as
222 *         one it handles.</p>
223 *     <li> <p>The <b>type</b> is retrieved from the Intent's data, if not
224 *         already supplied in the Intent.  Like the action, if a type is
225 *         included in the intent (either explicitly or implicitly in its
226 *         data), then this must be listed by the component as one it handles.</p>
227 *     <li> For data that is not a <code>content:</code> URI and where no explicit
228 *         type is included in the Intent, instead the <b>scheme</b> of the
229 *         intent data (such as <code>http:</code> or <code>mailto:</code>) is
230 *         considered. Again like the action, if we are matching a scheme it
231 *         must be listed by the component as one it can handle.
232 *     <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed
233 *         by the activity as categories it handles.  That is, if you include
234 *         the categories {@link #CATEGORY_LAUNCHER} and
235 *         {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components
236 *         with an intent that lists <em>both</em> of those categories.
237 *         Activities will very often need to support the
238 *         {@link #CATEGORY_DEFAULT} so that they can be found by
239 *         {@link Context#startActivity Context.startActivity()}.</p>
240 * </ul>
241 *
242 * <p>For example, consider the Note Pad sample application that
243 * allows user to browse through a list of notes data and view details about
244 * individual items.  Text in italics indicate places were you would replace a
245 * name with one specific to your own package.</p>
246 *

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

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

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

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

512 *
513 * <ul>
514 *     <li> {@link #ACTION_TIME_TICK}

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

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

823     * As a convenience, an Intent of this form can be created with the
824     * {@link #createChooser} function.
825     * <p>
826     * Input: No data should be specified.  get*Extra must have
827     * a {@link #EXTRA_INTENT} field containing the Intent being executed,
828     * and can optionally have a {@link #EXTRA_TITLE} field containing the

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