46/**
47 * An intent is an abstract description of an operation to be performed.  It
48 * can be used with {@link Context#startActivity(Intent) startActivity} to
49 * launch an {@link android.app.Activity},
50 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to
51 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components,
52 * and {@link android.content.Context#startService} or
53 * {@link android.content.Context#bindService} to communicate with a
54 * background {@link android.app.Service}.
55 *
56 * <p>An Intent provides a facility for performing late runtime binding between
57 * the code in different applications.  Its most significant use is in the
58 * launching of activities, where it can be thought of as the glue between
59 * activities. It is
60 * basically a passive data structure holding an abstract description of an
61 * action to be performed. The primary pieces of information in an intent
62 * are:</p>
63 *
64 * <ul>
65 *   <li> <p><b>action</b> -- The general action to be performed, such as
66 *     {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN},
67 *     etc.</p>
68 *   </li>
69 *   <li> <p><b>data</b> -- The data to operate on, such as a person record
70 *     in the contacts database, expressed as a {@link android.net.Uri}.</p>
71 *   </li>
72 * </ul>
73 *
74 *
75 * <p>Some examples of action/data pairs are:</p>
76 *
77 * <ul>
78 *   <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display
79 *     information about the person whose identifier is "1".</p>
80 *   </li>
81 *   <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display
82 *     the phone dialer with the person filled in.</p>
83 *   </li>
84 *   <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display
85 *     the phone dialer with the given number filled in.  Note how the
86 *     VIEW action does what what is considered the most reasonable thing for
87 *     a particular URI.</p>
88 *   </li>
89 *   <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display
90 *     the phone dialer with the given number filled in.</p>
91 *   </li>
92 *   <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit
93 *     information about the person whose identifier is "1".</p>
94 *   </li>
95 *   <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display
96 *     a list of people, which the user can browse through.  This example is a
97 *     typical top-level entry into the Contacts application, showing you the
98 *     list of people. Selecting a particular person to view would result in a
99 *     new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> }
100 *     being used to start an activity to display that person.</p>
101 *   </li>
102 * </ul>
103 *
104 * <p>In addition to these primary attributes, there are a number of secondary
105 * attributes that you can also include with an intent:</p>
106 *
107 * <ul>
108 *     <li> <p><b>category</b> -- Gives additional information about the action
109 *         to execute.  For example, {@link #CATEGORY_LAUNCHER} means it should
110 *         appear in the Launcher as a top-level application, while
111 *         {@link #CATEGORY_ALTERNATIVE} means it should be included in a list
112 *         of alternative actions the user can perform on a piece of data.</p>
113 *     <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the
114 *         intent data.  Normally the type is inferred from the data itself.
115 *         By setting this attribute, you disable that evaluation and force
116 *         an explicit type.</p>
117 *     <li> <p><b>component</b> -- Specifies an explicit name of a component
118 *         class to use for the intent.  Normally this is determined by looking
119 *         at the other information in the intent (the action, data/type, and
120 *         categories) and matching that with a component that can handle it.
121 *         If this attribute is set then none of the evaluation is performed,
122 *         and this component is used exactly as is.  By specifying this attribute,
123 *         all of the other Intent attributes become optional.</p>
124 *     <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information.
125 *         This can be used to provide extended information to the component.
126 *         For example, if we have a action to send an e-mail message, we could
127 *         also include extra pieces of data here to supply a subject, body,
128 *         etc.</p>
129 * </ul>
130 *
131 * <p>Here are some examples of other operations you can specify as intents
132 * using these additional parameters:</p>
133 *
134 * <ul>
135 *   <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> --
136 *     Launch the home screen.</p>
137 *   </li>
138 *   <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type
139 *     <i>{@link android.provider.Contacts.Phones#CONTENT_URI
140 *     vnd.android.cursor.item/phone}</i></b>
141 *     -- Display the list of people's phone numbers, allowing the user to
142 *     browse through them and pick one and return it to the parent activity.</p>
143 *   </li>
144 *   <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type
145 *     <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b>
146 *     -- Display all pickers for data that can be opened with
147 *     {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()},
148 *     allowing the user to pick one of them and then some data inside of it
149 *     and returning the resulting URI to the caller.  This can be used,
150 *     for example, in an e-mail application to allow the user to pick some
151 *     data to include as an attachment.</p>
152 *   </li>
153 * </ul>
154 *
155 * <p>There are a variety of standard Intent action and category constants
156 * defined in the Intent class, but applications can also define their own.
157 * These strings use java style scoping, to ensure they are unique -- for
158 * example, the standard {@link #ACTION_VIEW} is called
159 * "android.intent.action.VIEW".</p>
160 *
161 * <p>Put together, the set of actions, data types, categories, and extra data
162 * defines a language for the system allowing for the expression of phrases
163 * such as "call john smith's cell".  As applications are added to the system,
164 * they can extend this language by adding new actions, types, and categories, or
165 * they can modify the behavior of existing phrases by supplying their own
166 * activities that handle them.</p>
167 *
168 * <a name="IntentResolution"></a>
169 * <h3>Intent Resolution</h3>
170 *
171 * <p>There are two primary forms of intents you will use.
172 *
173 * <ul>
174 *     <li> <p><b>Explicit Intents</b> have specified a component (via
175 *     {@link #setComponent} or {@link #setClass}), which provides the exact
176 *     class to be run.  Often these will not include any other information,
177 *     simply being a way for an application to launch various internal
178 *     activities it has as the user interacts with the application.
179 *
180 *     <li> <p><b>Implicit Intents</b> have not specified a component;
181 *     instead, they must include enough information for the system to
182 *     determine which of the available components is best to run for that
183 *     intent.
184 * </ul>
185 *
186 * <p>When using implicit intents, given such an arbitrary intent we need to
187 * know what to do with it. This is handled by the process of <em>Intent
188 * resolution</em>, which maps an Intent to an {@link android.app.Activity},
189 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or
190 * more activities/receivers) that can handle it.</p>
191 *
192 * <p>The intent resolution mechanism basically revolves around matching an
193 * Intent against all of the &lt;intent-filter&gt; descriptions in the
194 * installed application packages.  (Plus, in the case of broadcasts, any {@link BroadcastReceiver}
195 * objects explicitly registered with {@link Context#registerReceiver}.)  More
196 * details on this can be found in the documentation on the {@link
197 * IntentFilter} class.</p>
198 *
199 * <p>There are three pieces of information in the Intent that are used for
200 * resolution: the action, type, and category.  Using this information, a query
201 * is done on the {@link PackageManager} for a component that can handle the
202 * intent. The appropriate component is determined based on the intent
203 * information supplied in the <code>AndroidManifest.xml</code> file as
204 * follows:</p>
205 *
206 * <ul>
207 *     <li> <p>The <b>action</b>, if given, must be listed by the component as
208 *         one it handles.</p>
209 *     <li> <p>The <b>type</b> is retrieved from the Intent's data, if not
210 *         already supplied in the Intent.  Like the action, if a type is
211 *         included in the intent (either explicitly or implicitly in its
212 *         data), then this must be listed by the component as one it handles.</p>
213 *     <li> For data that is not a <code>content:</code> URI and where no explicit
214 *         type is included in the Intent, instead the <b>scheme</b> of the
215 *         intent data (such as <code>http:</code> or <code>mailto:</code>) is
216 *         considered. Again like the action, if we are matching a scheme it
217 *         must be listed by the component as one it can handle.
218 *     <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed
219 *         by the activity as categories it handles.  That is, if you include
220 *         the categories {@link #CATEGORY_LAUNCHER} and
221 *         {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components
222 *         with an intent that lists <em>both</em> of those categories.
223 *         Activities will very often need to support the
224 *         {@link #CATEGORY_DEFAULT} so that they can be found by
225 *         {@link Context#startActivity Context.startActivity()}.</p>
226 * </ul>
227 *
228 * <p>For example, consider the Note Pad sample application that
229 * allows user to browse through a list of notes data and view details about
230 * individual items.  Text in italics indicate places were you would replace a
231 * name with one specific to your own package.</p>
232 *
233 * <pre> &lt;manifest xmlns:android="http://schemas.android.com/apk/res/android"

259 *

261 *             &lt;intent-filter android:label="@string/resolve_edit"&gt;

267 *
268 *             &lt;intent-filter&gt;
269 *                 &lt;action android:name="android.intent.action.INSERT" /&gt;
270 *                 &lt;category android:name="android.intent.category.DEFAULT" /&gt;

272 *             &lt;/intent-filter&gt;
273 *
274 *         &lt;/activity&gt;
275 *
276 *         &lt;activity class=".TitleEditor" android:label="@string/title_edit_title"
277 *                 android:theme="@android:style/Theme.Dialog"&gt;
278 *             &lt;intent-filter android:label="@string/resolve_title"&gt;
279 *                 &lt;action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /&gt;
280 *                 &lt;category android:name="android.intent.category.DEFAULT" /&gt;
281 *                 &lt;category android:name="android.intent.category.ALTERNATIVE" /&gt;
282 *                 &lt;category android:name="android.intent.category.SELECTED_ALTERNATIVE" /&gt;
283 *                 &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
284 *             &lt;/intent-filter&gt;
285 *         &lt;/activity&gt;
286 *
287 *     &lt;/application&gt;
288 * &lt;/manifest&gt;</pre>
289 *
290 * <p>The first activity,
291 * <code>com.android.notepad.NotesList</code>, serves as our main
292 * entry into the app.  It can do three things as described by its three intent
293 * templates:
294 * <ol>
295 * <li><pre>
296 * &lt;intent-filter&gt;
297 *     &lt;action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /&gt;
298 *     &lt;category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /&gt;
299 * &lt;/intent-filter&gt;</pre>
300 * <p>This provides a top-level entry into the NotePad application: the standard
301 * MAIN action is a main entry point (not requiring any other information in
302 * the Intent), and the LAUNCHER category says that this entry point should be
303 * listed in the application launcher.</p>
304 * <li><pre>
305 * &lt;intent-filter&gt;
306 *     &lt;action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /&gt;
307 *     &lt;action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /&gt;
308 *     &lt;action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /&gt;
309 *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
310 *     &lt;data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /&gt;
311 * &lt;/intent-filter&gt;</pre>
312 * <p>This declares the things that the activity can do on a directory of
313 * notes.  The type being supported is given with the &lt;type&gt; tag, where
314 * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which
315 * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can
316 * be retrieved which holds our note pad data (<code>vnd.google.note</code>).
317 * The activity allows the user to view or edit the directory of data (via
318 * the VIEW and EDIT actions), or to pick a particular note and return it
319 * to the caller (via the PICK action).  Note also the DEFAULT category
320 * supplied here: this is <em>required</em> for the
321 * {@link Context#startActivity Context.startActivity} method to resolve your
322 * activity when its component name is not explicitly specified.</p>
323 * <li><pre>
324 * &lt;intent-filter&gt;
325 *     &lt;action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /&gt;
326 *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
327 *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
328 * &lt;/intent-filter&gt;</pre>
329 * <p>This filter describes the ability return to the caller a note selected by
330 * the user without needing to know where it came from.  The data type
331 * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which
332 * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can
333 * be retrieved which contains our note pad data (<code>vnd.google.note</code>).
334 * The GET_CONTENT action is similar to the PICK action, where the activity
335 * will return to its caller a piece of data selected by the user.  Here,
336 * however, the caller specifies the type of data they desire instead of
337 * the type of data the user will be picking from.</p>
338 * </ol>
339 *
340 * <p>Given these capabilities, the following intents will resolve to the
341 * NotesList activity:</p>
342 *
343 * <ul>
344 *     <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the
345 *         activities that can be used as top-level entry points into an
346 *         application.</p>
347 *     <li> <p><b>{ action=android.app.action.MAIN,
348 *         category=android.app.category.LAUNCHER }</b> is the actual intent
349 *         used by the Launcher to populate its top-level list.</p>
350 *     <li> <p><b>{ action=android.intent.action.VIEW
351 *          data=content://com.google.provider.NotePad/notes }</b>
352 *         displays a list of all the notes under
353 *         "content://com.google.provider.NotePad/notes", which
354 *         the user can browse through and see the details on.</p>
355 *     <li> <p><b>{ action=android.app.action.PICK
356 *          data=content://com.google.provider.NotePad/notes }</b>
357 *         provides a list of the notes under
358 *         "content://com.google.provider.NotePad/notes", from which
359 *         the user can pick a note whose data URL is returned back to the caller.</p>
360 *     <li> <p><b>{ action=android.app.action.GET_CONTENT
361 *          type=vnd.android.cursor.item/vnd.google.note }</b>
362 *         is similar to the pick action, but allows the caller to specify the
363 *         kind of data they want back so that the system can find the appropriate
364 *         activity to pick something of that data type.</p>
365 * </ul>
366 *
367 * <p>The second activity,
368 * <code>com.android.notepad.NoteEditor</code>, shows the user a single
369 * note entry and allows them to edit it.  It can do two things as described
370 * by its two intent templates:
371 * <ol>
372 * <li><pre>
373 * &lt;intent-filter android:label="@string/resolve_edit"&gt;
374 *     &lt;action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /&gt;
375 *     &lt;action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /&gt;
376 *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
377 *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
378 * &lt;/intent-filter&gt;</pre>
379 * <p>The first, primary, purpose of this activity is to let the user interact
380 * with a single note, as decribed by the MIME type
381 * <code>vnd.android.cursor.item/vnd.google.note</code>.  The activity can
382 * either VIEW a note or allow the user to EDIT it.  Again we support the
383 * DEFAULT category to allow the activity to be launched without explicitly
384 * specifying its component.</p>
385 * <li><pre>
386 * &lt;intent-filter&gt;
387 *     &lt;action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /&gt;
388 *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
389 *     &lt;data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /&gt;
390 * &lt;/intent-filter&gt;</pre>
391 * <p>The secondary use of this activity is to insert a new note entry into
392 * an existing directory of notes.  This is used when the user creates a new
393 * note: the INSERT action is executed on the directory of notes, causing
394 * this activity to run and have the user create the new note data which
395 * it then adds to the content provider.</p>
396 * </ol>
397 *
398 * <p>Given these capabilities, the following intents will resolve to the
399 * NoteEditor activity:</p>
400 *
401 * <ul>
402 *     <li> <p><b>{ action=android.intent.action.VIEW
403 *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
404 *         shows the user the content of note <var>{ID}</var>.</p>
405 *     <li> <p><b>{ action=android.app.action.EDIT
406 *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
407 *         allows the user to edit the content of note <var>{ID}</var>.</p>
408 *     <li> <p><b>{ action=android.app.action.INSERT
409 *          data=content://com.google.provider.NotePad/notes }</b>
410 *         creates a new, empty note in the notes list at
411 *         "content://com.google.provider.NotePad/notes"
412 *         and allows the user to edit it.  If they keep their changes, the URI
413 *         of the newly created note is returned to the caller.</p>
414 * </ul>
415 *
416 * <p>The last activity,
417 * <code>com.android.notepad.TitleEditor</code>, allows the user to
418 * edit the title of a note.  This could be implemented as a class that the
419 * application directly invokes (by explicitly setting its component in
420 * the Intent), but here we show a way you can publish alternative
421 * operations on existing data:</p>
422 *
423 * <pre>
424 * &lt;intent-filter android:label="@string/resolve_title"&gt;
425 *     &lt;action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /&gt;
426 *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
427 *     &lt;category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /&gt;
428 *     &lt;category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /&gt;
429 *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
430 * &lt;/intent-filter&gt;</pre>
431 *
432 * <p>In the single intent template here, we
433 * have created our own private action called
434 * <code>com.android.notepad.action.EDIT_TITLE</code> which means to
435 * edit the title of a note.  It must be invoked on a specific note
436 * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous
437 * view and edit actions, but here displays and edits the title contained
438 * in the note data.
439 *
440 * <p>In addition to supporting the default category as usual, our title editor
441 * also supports two other standard categories: ALTERNATIVE and
442 * SELECTED_ALTERNATIVE.  Implementing
443 * these categories allows others to find the special action it provides
444 * without directly knowing about it, through the
445 * {@link android.content.pm.PackageManager#queryIntentActivityOptions} method, or
446 * more often to build dynamic menu items with
447 * {@link android.view.Menu#addIntentOptions}.  Note that in the intent
448 * template here was also supply an explicit name for the template
449 * (via <code>android:label="@string/resolve_title"</code>) to better control
450 * what the user sees when presented with this activity as an alternative
451 * action to the data they are viewing.
452 *
453 * <p>Given these capabilities, the following intent will resolve to the
454 * TitleEditor activity:</p>
455 *
456 * <ul>
457 *     <li> <p><b>{ action=com.android.notepad.action.EDIT_TITLE
458 *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
459 *         displays and allows the user to edit the title associated
460 *         with note <var>{ID}</var>.</p>
461 * </ul>
462 *
463 * <h3>Standard Activity Actions</h3>
464 *
465 * <p>These are the current standard actions that Intent defines for launching
466 * activities (usually through {@link Context#startActivity}.  The most
467 * important, and by far most frequently used, are {@link #ACTION_MAIN} and
468 * {@link #ACTION_EDIT}.
469 *
470 * <ul>
471 *     <li> {@link #ACTION_MAIN}
472 *     <li> {@link #ACTION_VIEW}
473 *     <li> {@link #ACTION_ATTACH_DATA}

490 *     <li> {@link #ACTION_FACTORY_TEST}
491 * </ul>
492 *
493 * <h3>Standard Broadcast Actions</h3>
494 *
495 * <p>These are the current standard actions that Intent defines for receiving
496 * broadcasts (usually through {@link Context#registerReceiver} or a
497 * &lt;receiver&gt; tag in a manifest).
498 *
499 * <ul>
500 *     <li> {@link #ACTION_TIME_TICK}
501 *     <li> {@link #ACTION_TIME_CHANGED}
502 *     <li> {@link #ACTION_TIMEZONE_CHANGED}
503 *     <li> {@link #ACTION_BOOT_COMPLETED}
504 *     <li> {@link #ACTION_PACKAGE_ADDED}
505 *     <li> {@link #ACTION_PACKAGE_CHANGED}
506 *     <li> {@link #ACTION_PACKAGE_REMOVED}
507 *     <li> {@link #ACTION_PACKAGE_RESTARTED}
508 *     <li> {@link #ACTION_PACKAGE_DATA_CLEARED}
509 *     <li> {@link #ACTION_UID_REMOVED}
510 *     <li> {@link #ACTION_BATTERY_CHANGED}
511 *     <li> {@link #ACTION_POWER_CONNECTED}
512 *     <li> {@link #ACTION_POWER_DISCONNECTED}
513 *     <li> {@link #ACTION_SHUTDOWN}
514 * </ul>
515 *
516 * <h3>Standard Categories</h3>
517 *
518 * <p>These are the current standard categories that can be used to further
519 * clarify an Intent via {@link #addCategory}.
520 *
521 * <ul>
522 *     <li> {@link #CATEGORY_DEFAULT}
523 *     <li> {@link #CATEGORY_BROWSABLE}
524 *     <li> {@link #CATEGORY_TAB}
525 *     <li> {@link #CATEGORY_ALTERNATIVE}
526 *     <li> {@link #CATEGORY_SELECTED_ALTERNATIVE}
527 *     <li> {@link #CATEGORY_LAUNCHER}
528 *     <li> {@link #CATEGORY_INFO}
529 *     <li> {@link #CATEGORY_HOME}
530 *     <li> {@link #CATEGORY_PREFERENCE}
531 *     <li> {@link #CATEGORY_TEST}
532 * </ul>
533 *
534 * <h3>Standard Extra Data</h3>
535 *
536 * <p>These are the current standard fields that can be used as extra data via
537 * {@link #putExtra}.
538 *
539 * <ul>
540 *     <li> {@link #EXTRA_TEMPLATE}
541 *     <li> {@link #EXTRA_INTENT}
542 *     <li> {@link #EXTRA_STREAM}
543 *     <li> {@link #EXTRA_TEXT}
544 * </ul>
545 *
546 * <h3>Flags</h3>
547 *
548 * <p>These are the possible flags that can be used in the Intent via
549 * {@link #setFlags} and {@link #addFlags}.  See {@link #setFlags} for a list
550 * of all possible flags.

801     * just say what kind of data is desired, not a URI of existing data from
802     * which the user can pick.  A ACTION_GET_CONTENT could allow the user to
803     * create the data as it runs (for example taking a picture or recording a
804     * sound), let them browser over the web and download the desired data,
805     * etc.
806     * <p>
807     * There are two main ways to use this action: if you want an specific kind
808     * of data, such as a person contact, you set the MIME type to the kind of
809     * data you want and launch it with {@link Context#startActivity(Intent)}.
810     * The system will then launch the best application to select that kind
811     * of data for you.
812     * <p>
813     * You may also be interested in any of a set of types of content the user
814     * can pick.  For example, an e-mail application that wants to allow the
815     * user to add an attachment to an e-mail message can use this action to
816     * bring up a list of all of the types of content the user can attach.
817     * <p>
818     * In this case, you should wrap the GET_CONTENT intent with a chooser
819     * (through {@link #createChooser}), which will give the proper interface
820     * for the user to pick how to send your data and allow you to specify
821     * a prompt indicating what they are doing.  You will usually specify a
822     * broad MIME type (such as image/* or {@literal *}/*), resulting in a
823     * broad range of content types the user can select from.
824     * <p>
825     * When using such a broad GET_CONTENT action, it is often desireable to
826     * only pick from data that can be represented as a stream.  This is
827     * accomplished by requiring the {@link #CATEGORY_OPENABLE} in the Intent.
828     * <p>
829     * Input: {@link #getType} is the desired MIME type to retrieve.  Note
830     * that no URI is supplied in the intent, as there are no constraints on
831     * where the returned data originally comes from.  You may also include the
832     * {@link #CATEGORY_OPENABLE} if you can only accept data that can be
833     * opened as a stream.
834     * <p>
