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

283 *             &lt;/intent-filter&gt;
284 *

286 *
287 *         &lt;activity class=".TitleEditor" android:label="@string/title_edit_title"
288 *                 android:theme="@android:style/Theme.Dialog"&gt;
289 *             &lt;intent-filter android:label="@string/resolve_title"&gt;
290 *                 &lt;action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /&gt;

292 *                 &lt;category android:name="android.intent.category.ALTERNATIVE" /&gt;
293 *                 &lt;category android:name="android.intent.category.SELECTED_ALTERNATIVE" /&gt;

295 *             &lt;/intent-filter&gt;
296 *         &lt;/activity&gt;
297 *
298 *     &lt;/application&gt;
299 * &lt;/manifest&gt;</pre>
300 *
301 * <p>The first activity,
302 * <code>com.android.notepad.NotesList</code>, serves as our main
303 * entry into the app.  It can do three things as described by its three intent
304 * templates:
305 * <ol>
306 * <li><pre>
307 * &lt;intent-filter&gt;
308 *     &lt;action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /&gt;
309 *     &lt;category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /&gt;
310 * &lt;/intent-filter&gt;</pre>
311 * <p>This provides a top-level entry into the NotePad application: the standard
312 * MAIN action is a main entry point (not requiring any other information in
313 * the Intent), and the LAUNCHER category says that this entry point should be
314 * listed in the application launcher.</p>
315 * <li><pre>
316 * &lt;intent-filter&gt;
317 *     &lt;action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /&gt;
318 *     &lt;action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /&gt;
319 *     &lt;action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /&gt;
320 *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
321 *     &lt;data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /&gt;
322 * &lt;/intent-filter&gt;</pre>
323 * <p>This declares the things that the activity can do on a directory of
324 * notes.  The type being supported is given with the &lt;type&gt; tag, where
325 * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which
326 * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can
327 * be retrieved which holds our note pad data (<code>vnd.google.note</code>).
328 * The activity allows the user to view or edit the directory of data (via
329 * the VIEW and EDIT actions), or to pick a particular note and return it
330 * to the caller (via the PICK action).  Note also the DEFAULT category
331 * supplied here: this is <em>required</em> for the
332 * {@link Context#startActivity Context.startActivity} method to resolve your
333 * activity when its component name is not explicitly specified.</p>
334 * <li><pre>
335 * &lt;intent-filter&gt;
336 *     &lt;action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /&gt;
337 *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
338 *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
339 * &lt;/intent-filter&gt;</pre>
340 * <p>This filter describes the ability return to the caller a note selected by
341 * the user without needing to know where it came from.  The data type
342 * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which
343 * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can
344 * be retrieved which contains our note pad data (<code>vnd.google.note</code>).
345 * The GET_CONTENT action is similar to the PICK action, where the activity
346 * will return to its caller a piece of data selected by the user.  Here,
347 * however, the caller specifies the type of data they desire instead of
348 * the type of data the user will be picking from.</p>
349 * </ol>
350 *
351 * <p>Given these capabilities, the following intents will resolve to the
352 * NotesList activity:</p>
353 *
354 * <ul>
355 *     <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the
356 *         activities that can be used as top-level entry points into an
357 *         application.</p>
358 *     <li> <p><b>{ action=android.app.action.MAIN,
359 *         category=android.app.category.LAUNCHER }</b> is the actual intent
360 *         used by the Launcher to populate its top-level list.</p>
361 *     <li> <p><b>{ action=android.intent.action.VIEW
362 *          data=content://com.google.provider.NotePad/notes }</b>
363 *         displays a list of all the notes under
364 *         "content://com.google.provider.NotePad/notes", which
365 *         the user can browse through and see the details on.</p>
366 *     <li> <p><b>{ action=android.app.action.PICK
367 *          data=content://com.google.provider.NotePad/notes }</b>
368 *         provides a list of the notes under
369 *         "content://com.google.provider.NotePad/notes", from which
370 *         the user can pick a note whose data URL is returned back to the caller.</p>
371 *     <li> <p><b>{ action=android.app.action.GET_CONTENT
372 *          type=vnd.android.cursor.item/vnd.google.note }</b>
373 *         is similar to the pick action, but allows the caller to specify the
374 *         kind of data they want back so that the system can find the appropriate
375 *         activity to pick something of that data type.</p>
376 * </ul>
377 *
378 * <p>The second activity,
379 * <code>com.android.notepad.NoteEditor</code>, shows the user a single
380 * note entry and allows them to edit it.  It can do two things as described
381 * by its two intent templates:
382 * <ol>
383 * <li><pre>
384 * &lt;intent-filter android:label="@string/resolve_edit"&gt;
385 *     &lt;action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /&gt;
386 *     &lt;action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /&gt;
387 *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
388 *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
389 * &lt;/intent-filter&gt;</pre>
390 * <p>The first, primary, purpose of this activity is to let the user interact
391 * with a single note, as decribed by the MIME type
392 * <code>vnd.android.cursor.item/vnd.google.note</code>.  The activity can
393 * either VIEW a note or allow the user to EDIT it.  Again we support the
394 * DEFAULT category to allow the activity to be launched without explicitly
395 * specifying its component.</p>
396 * <li><pre>
397 * &lt;intent-filter&gt;
398 *     &lt;action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /&gt;
399 *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
400 *     &lt;data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /&gt;
401 * &lt;/intent-filter&gt;</pre>
402 * <p>The secondary use of this activity is to insert a new note entry into
403 * an existing directory of notes.  This is used when the user creates a new
404 * note: the INSERT action is executed on the directory of notes, causing
405 * this activity to run and have the user create the new note data which
406 * it then adds to the content provider.</p>
407 * </ol>
408 *
409 * <p>Given these capabilities, the following intents will resolve to the
410 * NoteEditor activity:</p>
411 *
412 * <ul>
413 *     <li> <p><b>{ action=android.intent.action.VIEW
414 *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
415 *         shows the user the content of note <var>{ID}</var>.</p>
416 *     <li> <p><b>{ action=android.app.action.EDIT
417 *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
418 *         allows the user to edit the content of note <var>{ID}</var>.</p>
419 *     <li> <p><b>{ action=android.app.action.INSERT
420 *          data=content://com.google.provider.NotePad/notes }</b>
421 *         creates a new, empty note in the notes list at
422 *         "content://com.google.provider.NotePad/notes"
423 *         and allows the user to edit it.  If they keep their changes, the URI
424 *         of the newly created note is returned to the caller.</p>
425 * </ul>
426 *
427 * <p>The last activity,
428 * <code>com.android.notepad.TitleEditor</code>, allows the user to
429 * edit the title of a note.  This could be implemented as a class that the
430 * application directly invokes (by explicitly setting its component in
431 * the Intent), but here we show a way you can publish alternative
432 * operations on existing data:</p>
433 *
434 * <pre>
435 * &lt;intent-filter android:label="@string/resolve_title"&gt;
436 *     &lt;action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /&gt;
437 *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
438 *     &lt;category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /&gt;
439 *     &lt;category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /&gt;
440 *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
441 * &lt;/intent-filter&gt;</pre>
442 *
443 * <p>In the single intent template here, we
444 * have created our own private action called
445 * <code>com.android.notepad.action.EDIT_TITLE</code> which means to
446 * edit the title of a note.  It must be invoked on a specific note
447 * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous
448 * view and edit actions, but here displays and edits the title contained
449 * in the note data.
450 *
451 * <p>In addition to supporting the default category as usual, our title editor
452 * also supports two other standard categories: ALTERNATIVE and
453 * SELECTED_ALTERNATIVE.  Implementing
454 * these categories allows others to find the special action it provides
455 * without directly knowing about it, through the
456 * {@link android.content.pm.PackageManager#queryIntentActivityOptions} method, or
457 * more often to build dynamic menu items with
458 * {@link android.view.Menu#addIntentOptions}.  Note that in the intent
459 * template here was also supply an explicit name for the template
460 * (via <code>android:label="@string/resolve_title"</code>) to better control
461 * what the user sees when presented with this activity as an alternative
462 * action to the data they are viewing.
463 *
464 * <p>Given these capabilities, the following intent will resolve to the
465 * TitleEditor activity:</p>
466 *
467 * <ul>
468 *     <li> <p><b>{ action=com.android.notepad.action.EDIT_TITLE
469 *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
470 *         displays and allows the user to edit the title associated
471 *         with note <var>{ID}</var>.</p>
472 * </ul>
473 *
474 * <h3>Standard Activity Actions</h3>
475 *
476 * <p>These are the current standard actions that Intent defines for launching
477 * activities (usually through {@link Context#startActivity}.  The most
478 * important, and by far most frequently used, are {@link #ACTION_MAIN} and
479 * {@link #ACTION_EDIT}.
480 *
481 * <ul>
482 *     <li> {@link #ACTION_MAIN}

502 * </ul>
503 *
504 * <h3>Standard Broadcast Actions</h3>
505 *
506 * <p>These are the current standard actions that Intent defines for receiving
507 * broadcasts (usually through {@link Context#registerReceiver} or a
508 * &lt;receiver&gt; tag in a manifest).
509 *
510 * <ul>
511 *     <li> {@link #ACTION_TIME_TICK}

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

548 *     <li> {@link #CATEGORY_APP_MARKET}
549 * </ul>
550 *

555 *
556 * <ul>
557 *     <li> {@link #EXTRA_ALARM_COUNT}

783     * Activity Action: Display an activity chooser, allowing the user to pick
784     * what they want to before proceeding.  This can be used as an alternative
785     * to the standard activity picker that is displayed by the system when
786     * you try to start an activity with multiple possible matches, with these
787     * differences in behavior:
788     * <ul>
789     * <li>You can specify the title that will appear in the activity chooser.
790     * <li>The user does not have the option to make one of the matching
791     * activities a preferred activity, and all possible activities will
792     * always be shown even if one of them is currently marked as the
793     * preferred activity.
794     * </ul>
795     * <p>
796     * This action should be used when the user will naturally expect to
797     * select an activity in order to proceed.  An example if when not to use
798     * it is when the user clicks on a "mailto:" link.  They would naturally
799     * expect to go directly to their mail app, so startActivity() should be
800     * called directly: it will
801     * either launch the current preferred app, or put up a dialog allowing the
802     * user to pick an app to use and optionally marking that as preferred.
803     * <p>
804     * In contrast, if the user is selecting a menu item to send a picture
805     * they are viewing to someone else, there are many different things they
806     * may want to do at this point: send it through e-mail, upload it to a
807     * web service, etc.  In this case the CHOOSER action should be used, to
808     * always present to the user a list of the things they can do, with a
809     * nice title given by the caller such as "Send this photo with:".
810     * <p>
811     * As a convenience, an Intent of this form can be created with the
812     * {@link #createChooser} function.
813     * <p>Input: No data should be specified.  get*Extra must have
814     * a {@link #EXTRA_INTENT} field containing the Intent being executed,
815     * and can optionally have a {@link #EXTRA_TITLE} field containing the
816     * title text to display in the chooser.

841     * Activity Action: Allow the user to select a particular kind of data and

843     * just say what kind of data is desired, not a URI of existing data from
844     * which the user can pick.  A ACTION_GET_CONTENT could allow the user to
845     * create the data as it runs (for example taking a picture or recording a
846     * sound), let them browse over the web and download the desired data,
847     * etc.
848     * <p>
849     * There are two main ways to use this action: if you want a specific kind
850     * of data, such as a person contact, you set the MIME type to the kind of
851     * data you want and launch it with {@link Context#startActivity(Intent)}.
852     * The system will then launch the best application to select that kind
853     * of data for you.
854     * <p>
855     * You may also be interested in any of a set of types of content the user
856     * can pick.  For example, an e-mail application that wants to allow the
857     * user to add an attachment to an e-mail message can use this action to
858     * bring up a list of all of the types of content the user can attach.
859     * <p>
860     * In this case, you should wrap the GET_CONTENT intent with a chooser
861     * (through {@link #createChooser}), which will give the proper interface
862     * for the user to pick how to send your data and allow you to specify
863     * a prompt indicating what they are doing.  You will usually specify a
864     * broad MIME type (such as image/* or {@literal *}/*), resulting in a
865     * broad range of content types the user can select from.
866     * <p>
867     * When using such a broad GET_CONTENT action, it is often desirable to
868     * only pick from data that can be represented as a stream.  This is
869     * accomplished by requiring the {@link #CATEGORY_OPENABLE} in the Intent.
870     * <p>
871     * Callers can optionally specify {@link #EXTRA_LOCAL_ONLY} to request that
872     * the launched content chooser only returns results representing data that
873     * is locally available on the device.  For example, if this extra is set
874     * to true then an image picker should not show any pictures that are available
875     * from a remote server but not already on the local device (thus requiring
876     * they be downloaded when opened).
877     * <p>
878     * Input: {@link #getType} is the desired MIME type to retrieve.  Note
879     * that no URI is supplied in the intent, as there are no constraints on
880     * where the returned data originally comes from.  You may also include the
881     * {@link #CATEGORY_OPENABLE} if you can only accept data that can be
882     * opened as a stream.  You may use {@link #EXTRA_LOCAL_ONLY} to limit content
883     * selection to local data.
884     * <p>

4778     * a generic protocol while targeting it more specifically.
4779     *
4780     * <p>An example of where this may be used is with things like
4781     * {@link #CATEGORY_APP_BROWSER}.  This category allows you to build an
4782     * Intent that will launch the Browser application.  However, the correct

4784     * {@link #CATEGORY_LAUNCHER} with {@link #setComponent(ComponentName)}

4787     * previously or later launches it the normal way, since they do not match.
4788     * Instead, you can build an Intent with the MAIN action (but no ComponentName
4789     * yet specified) and set a selector with {@link #ACTION_MAIN} and
4790     * {@link #CATEGORY_APP_BROWSER} to point it specifically to the browser activity.
4791     *
4792     * <p>Setting a selector does not impact the behavior of
4793     * {@link #filterEquals(Intent)} and {@link #filterHashCode()}.  This is part of the
4794     * desired behavior of a selector -- it does not impact the base meaning
4795     * of the Intent, just what kinds of things will be matched against it
4796     * when determining who can handle it.</p>
4797     *
