61/**
62 * An intent is an abstract description of an operation to be performed.  It
63 * can be used with {@link Context#startActivity(Intent) startActivity} to
64 * launch an {@link android.app.Activity},
65 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to
66 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components,
67 * and {@link android.content.Context#startService} or
68 * {@link android.content.Context#bindService} to communicate with a
69 * background {@link android.app.Service}.
70 *
71 * <p>An Intent provides a facility for performing late runtime binding between the code in
72 * different applications. Its most significant use is in the launching of activities, where it
73 * can be thought of as the glue between activities. It is basically a passive data structure
74 * holding an abstract description of an action to be performed.</p>
75 *
76 * <div class="special reference">
77 * <h3>Developer Guides</h3>
78 * <p>For information about how to create and resolve intents, read the
79 * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a>
80 * developer guide.</p>
81 * </div>
82 *
83 * <a name="IntentStructure"></a>
84 * <h3>Intent Structure</h3>
85 * <p>The primary pieces of information in an intent are:</p>
86 *
87 * <ul>
88 *   <li> <p><b>action</b> -- The general action to be performed, such as
89 *     {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN},
90 *     etc.</p>
91 *   </li>
92 *   <li> <p><b>data</b> -- The data to operate on, such as a person record
93 *     in the contacts database, expressed as a {@link android.net.Uri}.</p>
94 *   </li>
95 * </ul>
96 *
97 *
98 * <p>Some examples of action/data pairs are:</p>
99 *
100 * <ul>
101 *   <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display
102 *     information about the person whose identifier is "1".</p>
103 *   </li>
104 *   <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display
105 *     the phone dialer with the person filled in.</p>
106 *   </li>
107 *   <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display
108 *     the phone dialer with the given number filled in.  Note how the
109 *     VIEW action does what what is considered the most reasonable thing for
110 *     a particular URI.</p>
111 *   </li>
112 *   <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display
113 *     the phone dialer with the given number filled in.</p>
114 *   </li>
115 *   <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit
116 *     information about the person whose identifier is "1".</p>
117 *   </li>
118 *   <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display
119 *     a list of people, which the user can browse through.  This example is a
120 *     typical top-level entry into the Contacts application, showing you the
121 *     list of people. Selecting a particular person to view would result in a
122 *     new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> }
123 *     being used to start an activity to display that person.</p>
124 *   </li>
125 * </ul>
126 *
127 * <p>In addition to these primary attributes, there are a number of secondary
128 * attributes that you can also include with an intent:</p>
129 *
130 * <ul>
131 *     <li> <p><b>category</b> -- Gives additional information about the action
132 *         to execute.  For example, {@link #CATEGORY_LAUNCHER} means it should
133 *         appear in the Launcher as a top-level application, while
134 *         {@link #CATEGORY_ALTERNATIVE} means it should be included in a list
135 *         of alternative actions the user can perform on a piece of data.</p>
136 *     <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the
137 *         intent data.  Normally the type is inferred from the data itself.
138 *         By setting this attribute, you disable that evaluation and force
139 *         an explicit type.</p>
140 *     <li> <p><b>component</b> -- Specifies an explicit name of a component
141 *         class to use for the intent.  Normally this is determined by looking
142 *         at the other information in the intent (the action, data/type, and
143 *         categories) and matching that with a component that can handle it.
144 *         If this attribute is set then none of the evaluation is performed,
145 *         and this component is used exactly as is.  By specifying this attribute,
146 *         all of the other Intent attributes become optional.</p>
147 *     <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information.
148 *         This can be used to provide extended information to the component.
149 *         For example, if we have a action to send an e-mail message, we could
150 *         also include extra pieces of data here to supply a subject, body,
151 *         etc.</p>
152 * </ul>
153 *
154 * <p>Here are some examples of other operations you can specify as intents
155 * using these additional parameters:</p>
156 *
157 * <ul>
158 *   <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> --
159 *     Launch the home screen.</p>
160 *   </li>
161 *   <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type
162 *     <i>{@link android.provider.Contacts.Phones#CONTENT_URI
163 *     vnd.android.cursor.item/phone}</i></b>
164 *     -- Display the list of people's phone numbers, allowing the user to
165 *     browse through them and pick one and return it to the parent activity.</p>
166 *   </li>
167 *   <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type
168 *     <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b>
169 *     -- Display all pickers for data that can be opened with
170 *     {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()},
171 *     allowing the user to pick one of them and then some data inside of it
172 *     and returning the resulting URI to the caller.  This can be used,
173 *     for example, in an e-mail application to allow the user to pick some
174 *     data to include as an attachment.</p>
175 *   </li>
176 * </ul>
177 *
178 * <p>There are a variety of standard Intent action and category constants
179 * defined in the Intent class, but applications can also define their own.
180 * These strings use java style scoping, to ensure they are unique -- for
181 * example, the standard {@link #ACTION_VIEW} is called
182 * "android.intent.action.VIEW".</p>
183 *
184 * <p>Put together, the set of actions, data types, categories, and extra data
185 * defines a language for the system allowing for the expression of phrases
186 * such as "call john smith's cell".  As applications are added to the system,
187 * they can extend this language by adding new actions, types, and categories, or
188 * they can modify the behavior of existing phrases by supplying their own
189 * activities that handle them.</p>
190 *
191 * <a name="IntentResolution"></a>
192 * <h3>Intent Resolution</h3>
193 *
194 * <p>There are two primary forms of intents you will use.
195 *
196 * <ul>
197 *     <li> <p><b>Explicit Intents</b> have specified a component (via
198 *     {@link #setComponent} or {@link #setClass}), which provides the exact
199 *     class to be run.  Often these will not include any other information,
200 *     simply being a way for an application to launch various internal
201 *     activities it has as the user interacts with the application.
202 *
203 *     <li> <p><b>Implicit Intents</b> have not specified a component;
204 *     instead, they must include enough information for the system to
205 *     determine which of the available components is best to run for that
206 *     intent.
207 * </ul>
208 *
209 * <p>When using implicit intents, given such an arbitrary intent we need to
210 * know what to do with it. This is handled by the process of <em>Intent
211 * resolution</em>, which maps an Intent to an {@link android.app.Activity},
212 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or
213 * more activities/receivers) that can handle it.</p>
214 *
215 * <p>The intent resolution mechanism basically revolves around matching an
216 * Intent against all of the &lt;intent-filter&gt; descriptions in the
217 * installed application packages.  (Plus, in the case of broadcasts, any {@link BroadcastReceiver}
218 * objects explicitly registered with {@link Context#registerReceiver}.)  More
219 * details on this can be found in the documentation on the {@link
220 * IntentFilter} class.</p>
221 *
222 * <p>There are three pieces of information in the Intent that are used for
223 * resolution: the action, type, and category.  Using this information, a query
224 * is done on the {@link PackageManager} for a component that can handle the
225 * intent. The appropriate component is determined based on the intent
226 * information supplied in the <code>AndroidManifest.xml</code> file as
227 * follows:</p>
228 *
229 * <ul>
230 *     <li> <p>The <b>action</b>, if given, must be listed by the component as
231 *         one it handles.</p>
232 *     <li> <p>The <b>type</b> is retrieved from the Intent's data, if not
233 *         already supplied in the Intent.  Like the action, if a type is
234 *         included in the intent (either explicitly or implicitly in its
235 *         data), then this must be listed by the component as one it handles.</p>
236 *     <li> For data that is not a <code>content:</code> URI and where no explicit
237 *         type is included in the Intent, instead the <b>scheme</b> of the
238 *         intent data (such as <code>http:</code> or <code>mailto:</code>) is
239 *         considered. Again like the action, if we are matching a scheme it
240 *         must be listed by the component as one it can handle.
241 *     <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed
242 *         by the activity as categories it handles.  That is, if you include
243 *         the categories {@link #CATEGORY_LAUNCHER} and
244 *         {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components
245 *         with an intent that lists <em>both</em> of those categories.
246 *         Activities will very often need to support the
247 *         {@link #CATEGORY_DEFAULT} so that they can be found by
248 *         {@link Context#startActivity Context.startActivity()}.</p>
249 * </ul>
250 *
251 * <p>For example, consider the Note Pad sample application that
252 * allows user to browse through a list of notes data and view details about
253 * individual items.  Text in italics indicate places were you would replace a
254 * name with one specific to your own package.</p>
255 *

295 *             &lt;/intent-filter&gt;
296 *
297 *         &lt;/activity&gt;
298 *
299 *         &lt;activity class=".TitleEditor" android:label="@string/title_edit_title"
300 *                 android:theme="@android:style/Theme.Dialog"&gt;
301 *             &lt;intent-filter android:label="@string/resolve_title"&gt;
302 *                 &lt;action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /&gt;

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

307 *             &lt;/intent-filter&gt;
308 *         &lt;/activity&gt;
309 *
310 *     &lt;/application&gt;
311 * &lt;/manifest&gt;</pre>
312 *
313 * <p>The first activity,
314 * <code>com.android.notepad.NotesList</code>, serves as our main
315 * entry into the app.  It can do three things as described by its three intent
316 * templates:
317 * <ol>
318 * <li><pre>
319 * &lt;intent-filter&gt;
320 *     &lt;action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /&gt;
321 *     &lt;category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /&gt;
322 * &lt;/intent-filter&gt;</pre>
323 * <p>This provides a top-level entry into the NotePad application: the standard
324 * MAIN action is a main entry point (not requiring any other information in
325 * the Intent), and the LAUNCHER category says that this entry point should be
326 * listed in the application launcher.</p>
327 * <li><pre>
328 * &lt;intent-filter&gt;
329 *     &lt;action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /&gt;
330 *     &lt;action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /&gt;
331 *     &lt;action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /&gt;
332 *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
333 *     &lt;data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /&gt;
334 * &lt;/intent-filter&gt;</pre>
335 * <p>This declares the things that the activity can do on a directory of
336 * notes.  The type being supported is given with the &lt;type&gt; tag, where
337 * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which
338 * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can
339 * be retrieved which holds our note pad data (<code>vnd.google.note</code>).
340 * The activity allows the user to view or edit the directory of data (via
341 * the VIEW and EDIT actions), or to pick a particular note and return it
342 * to the caller (via the PICK action).  Note also the DEFAULT category
343 * supplied here: this is <em>required</em> for the
344 * {@link Context#startActivity Context.startActivity} method to resolve your
345 * activity when its component name is not explicitly specified.</p>
346 * <li><pre>
347 * &lt;intent-filter&gt;
348 *     &lt;action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /&gt;
349 *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
350 *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
351 * &lt;/intent-filter&gt;</pre>
352 * <p>This filter describes the ability return to the caller a note selected by
353 * the user without needing to know where it came from.  The data type
354 * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which
355 * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can
356 * be retrieved which contains our note pad data (<code>vnd.google.note</code>).
357 * The GET_CONTENT action is similar to the PICK action, where the activity
358 * will return to its caller a piece of data selected by the user.  Here,
359 * however, the caller specifies the type of data they desire instead of
360 * the type of data the user will be picking from.</p>
361 * </ol>
362 *
363 * <p>Given these capabilities, the following intents will resolve to the
364 * NotesList activity:</p>
365 *
366 * <ul>
367 *     <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the
368 *         activities that can be used as top-level entry points into an
369 *         application.</p>
370 *     <li> <p><b>{ action=android.app.action.MAIN,
371 *         category=android.app.category.LAUNCHER }</b> is the actual intent
372 *         used by the Launcher to populate its top-level list.</p>
373 *     <li> <p><b>{ action=android.intent.action.VIEW
374 *          data=content://com.google.provider.NotePad/notes }</b>
375 *         displays a list of all the notes under
376 *         "content://com.google.provider.NotePad/notes", which
377 *         the user can browse through and see the details on.</p>
378 *     <li> <p><b>{ action=android.app.action.PICK
379 *          data=content://com.google.provider.NotePad/notes }</b>
380 *         provides a list of the notes under
381 *         "content://com.google.provider.NotePad/notes", from which
382 *         the user can pick a note whose data URL is returned back to the caller.</p>
383 *     <li> <p><b>{ action=android.app.action.GET_CONTENT
384 *          type=vnd.android.cursor.item/vnd.google.note }</b>
385 *         is similar to the pick action, but allows the caller to specify the
386 *         kind of data they want back so that the system can find the appropriate
387 *         activity to pick something of that data type.</p>
388 * </ul>
389 *
390 * <p>The second activity,
391 * <code>com.android.notepad.NoteEditor</code>, shows the user a single
392 * note entry and allows them to edit it.  It can do two things as described
393 * by its two intent templates:
394 * <ol>
395 * <li><pre>
396 * &lt;intent-filter android:label="@string/resolve_edit"&gt;
397 *     &lt;action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /&gt;
398 *     &lt;action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /&gt;
399 *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
400 *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
401 * &lt;/intent-filter&gt;</pre>
402 * <p>The first, primary, purpose of this activity is to let the user interact
403 * with a single note, as decribed by the MIME type
404 * <code>vnd.android.cursor.item/vnd.google.note</code>.  The activity can
405 * either VIEW a note or allow the user to EDIT it.  Again we support the
406 * DEFAULT category to allow the activity to be launched without explicitly
407 * specifying its component.</p>
408 * <li><pre>
409 * &lt;intent-filter&gt;
410 *     &lt;action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /&gt;
411 *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
412 *     &lt;data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /&gt;
413 * &lt;/intent-filter&gt;</pre>
414 * <p>The secondary use of this activity is to insert a new note entry into
415 * an existing directory of notes.  This is used when the user creates a new
416 * note: the INSERT action is executed on the directory of notes, causing
417 * this activity to run and have the user create the new note data which
418 * it then adds to the content provider.</p>
419 * </ol>
420 *
421 * <p>Given these capabilities, the following intents will resolve to the
422 * NoteEditor activity:</p>
423 *
424 * <ul>
425 *     <li> <p><b>{ action=android.intent.action.VIEW
426 *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
427 *         shows the user the content of note <var>{ID}</var>.</p>
428 *     <li> <p><b>{ action=android.app.action.EDIT
429 *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
430 *         allows the user to edit the content of note <var>{ID}</var>.</p>
431 *     <li> <p><b>{ action=android.app.action.INSERT
432 *          data=content://com.google.provider.NotePad/notes }</b>
433 *         creates a new, empty note in the notes list at
434 *         "content://com.google.provider.NotePad/notes"
435 *         and allows the user to edit it.  If they keep their changes, the URI
436 *         of the newly created note is returned to the caller.</p>
437 * </ul>
438 *
439 * <p>The last activity,
440 * <code>com.android.notepad.TitleEditor</code>, allows the user to
441 * edit the title of a note.  This could be implemented as a class that the
442 * application directly invokes (by explicitly setting its component in
443 * the Intent), but here we show a way you can publish alternative
444 * operations on existing data:</p>
445 *
446 * <pre>
447 * &lt;intent-filter android:label="@string/resolve_title"&gt;
448 *     &lt;action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /&gt;
449 *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
450 *     &lt;category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /&gt;
451 *     &lt;category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /&gt;
452 *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
453 * &lt;/intent-filter&gt;</pre>
454 *
455 * <p>In the single intent template here, we
456 * have created our own private action called
457 * <code>com.android.notepad.action.EDIT_TITLE</code> which means to
458 * edit the title of a note.  It must be invoked on a specific note
459 * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous
460 * view and edit actions, but here displays and edits the title contained
461 * in the note data.
462 *
463 * <p>In addition to supporting the default category as usual, our title editor
464 * also supports two other standard categories: ALTERNATIVE and
465 * SELECTED_ALTERNATIVE.  Implementing
466 * these categories allows others to find the special action it provides
467 * without directly knowing about it, through the
468 * {@link android.content.pm.PackageManager#queryIntentActivityOptions} method, or
469 * more often to build dynamic menu items with
470 * {@link android.view.Menu#addIntentOptions}.  Note that in the intent
471 * template here was also supply an explicit name for the template
472 * (via <code>android:label="@string/resolve_title"</code>) to better control
473 * what the user sees when presented with this activity as an alternative
474 * action to the data they are viewing.
475 *
476 * <p>Given these capabilities, the following intent will resolve to the
477 * TitleEditor activity:</p>
478 *
479 * <ul>
480 *     <li> <p><b>{ action=com.android.notepad.action.EDIT_TITLE
481 *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
482 *         displays and allows the user to edit the title associated
483 *         with note <var>{ID}</var>.</p>
484 * </ul>
485 *
486 * <h3>Standard Activity Actions</h3>
487 *
488 * <p>These are the current standard actions that Intent defines for launching
489 * activities (usually through {@link Context#startActivity}.  The most
490 * important, and by far most frequently used, are {@link #ACTION_MAIN} and
491 * {@link #ACTION_EDIT}.
492 *

515 *
516 * <h3>Standard Broadcast Actions</h3>
517 *
518 * <p>These are the current standard actions that Intent defines for receiving
519 * broadcasts (usually through {@link Context#registerReceiver} or a

534 *     <li> {@link #ACTION_POWER_CONNECTED}
535 *     <li> {@link #ACTION_POWER_DISCONNECTED}
536 *     <li> {@link #ACTION_SHUTDOWN}
537 * </ul>
538 *
539 * <h3>Standard Categories</h3>
540 *
541 * <p>These are the current standard categories that can be used to further
542 * clarify an Intent via {@link #addCategory}.
543 *
544 * <ul>
545 *     <li> {@link #CATEGORY_DEFAULT}
546 *     <li> {@link #CATEGORY_BROWSABLE}
547 *     <li> {@link #CATEGORY_TAB}
548 *     <li> {@link #CATEGORY_ALTERNATIVE}
549 *     <li> {@link #CATEGORY_SELECTED_ALTERNATIVE}
550 *     <li> {@link #CATEGORY_LAUNCHER}

809     * you try to start an activity with multiple possible matches, with these
810     * differences in behavior:
811     * <ul>
812     * <li>You can specify the title that will appear in the activity chooser.
813     * <li>The user does not have the option to make one of the matching
814     * activities a preferred activity, and all possible activities will
815     * always be shown even if one of them is currently marked as the
816     * preferred activity.
817     * </ul>
818     * <p>
819     * This action should be used when the user will naturally expect to
820     * select an activity in order to proceed.  An example if when not to use
821     * it is when the user clicks on a "mailto:" link.  They would naturally
822     * expect to go directly to their mail app, so startActivity() should be
823     * called directly: it will
824     * either launch the current preferred app, or put up a dialog allowing the
825     * user to pick an app to use and optionally marking that as preferred.
826     * <p>
827     * In contrast, if the user is selecting a menu item to send a picture
828     * they are viewing to someone else, there are many different things they
829     * may want to do at this point: send it through e-mail, upload it to a
830     * web service, etc.  In this case the CHOOSER action should be used, to
831     * always present to the user a list of the things they can do, with a
832     * nice title given by the caller such as "Send this photo with:".
833     * <p>
834     * If you need to grant URI permissions through a chooser, you must specify
835     * the permissions to be granted on the ACTION_CHOOSER Intent
836     * <em>in addition</em> to the EXTRA_INTENT inside.  This means using
837     * {@link #setClipData} to specify the URIs to be granted as well as
838     * {@link #FLAG_GRANT_READ_URI_PERMISSION} and/or
839     * {@link #FLAG_GRANT_WRITE_URI_PERMISSION} as appropriate.

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