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

279  *
280  *             &lt;intent-filter&gt;
281  *                 &lt;action android:name="android.intent.action.INSERT" /&gt;
282  *                 &lt;category android:name="android.intent.category.DEFAULT" /&gt;

284  *             &lt;/intent-filter&gt;
285  *
286  *         &lt;/activity&gt;
287  *
288  *         &lt;activity class=".TitleEditor" android:label="@string/title_edit_title"
289  *                 android:theme="@android:style/Theme.Dialog"&gt;
290  *             &lt;intent-filter android:label="@string/resolve_title"&gt;
291  *                 &lt;action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /&gt;
292  *                 &lt;category android:name="android.intent.category.DEFAULT" /&gt;
293  *                 &lt;category android:name="android.intent.category.ALTERNATIVE" /&gt;
294  *                 &lt;category android:name="android.intent.category.SELECTED_ALTERNATIVE" /&gt;
295  *                 &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
296  *             &lt;/intent-filter&gt;
297  *         &lt;/activity&gt;
298  *
299  *     &lt;/application&gt;
300  * &lt;/manifest&gt;</pre>
301  *
302  * <p>The first activity,
303  * <code>com.android.notepad.NotesList</code>, serves as our main
304  * entry into the app.  It can do three things as described by its three intent
305  * templates:
306  * <ol>
307  * <li><pre>
308  * &lt;intent-filter&gt;
309  *     &lt;action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /&gt;
310  *     &lt;category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /&gt;
311  * &lt;/intent-filter&gt;</pre>
312  * <p>This provides a top-level entry into the NotePad application: the standard
313  * MAIN action is a main entry point (not requiring any other information in
314  * the Intent), and the LAUNCHER category says that this entry point should be
315  * listed in the application launcher.</p>
316  * <li><pre>
317  * &lt;intent-filter&gt;
318  *     &lt;action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /&gt;
319  *     &lt;action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /&gt;
320  *     &lt;action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /&gt;
321  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
322  *     &lt;data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /&gt;
323  * &lt;/intent-filter&gt;</pre>
324  * <p>This declares the things that the activity can do on a directory of
325  * notes.  The type being supported is given with the &lt;type&gt; tag, where
326  * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which
327  * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can
328  * be retrieved which holds our note pad data (<code>vnd.google.note</code>).
329  * The activity allows the user to view or edit the directory of data (via
330  * the VIEW and EDIT actions), or to pick a particular note and return it
331  * to the caller (via the PICK action).  Note also the DEFAULT category
332  * supplied here: this is <em>required</em> for the
333  * {@link Context#startActivity Context.startActivity} method to resolve your
334  * activity when its component name is not explicitly specified.</p>
335  * <li><pre>
336  * &lt;intent-filter&gt;
337  *     &lt;action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /&gt;
338  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
339  *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
340  * &lt;/intent-filter&gt;</pre>
341  * <p>This filter describes the ability return to the caller a note selected by
342  * the user without needing to know where it came from.  The data type
343  * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which
344  * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can
345  * be retrieved which contains our note pad data (<code>vnd.google.note</code>).
346  * The GET_CONTENT action is similar to the PICK action, where the activity
347  * will return to its caller a piece of data selected by the user.  Here,
348  * however, the caller specifies the type of data they desire instead of
349  * the type of data the user will be picking from.</p>
350  * </ol>
351  *
352  * <p>Given these capabilities, the following intents will resolve to the
353  * NotesList activity:</p>
354  *
355  * <ul>
356  *     <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the
357  *         activities that can be used as top-level entry points into an
358  *         application.</p>
359  *     <li> <p><b>{ action=android.app.action.MAIN,
360  *         category=android.app.category.LAUNCHER }</b> is the actual intent
361  *         used by the Launcher to populate its top-level list.</p>
362  *     <li> <p><b>{ action=android.intent.action.VIEW
363  *          data=content://com.google.provider.NotePad/notes }</b>
364  *         displays a list of all the notes under
365  *         "content://com.google.provider.NotePad/notes", which
366  *         the user can browse through and see the details on.</p>
367  *     <li> <p><b>{ action=android.app.action.PICK
368  *          data=content://com.google.provider.NotePad/notes }</b>
369  *         provides a list of the notes under
370  *         "content://com.google.provider.NotePad/notes", from which
371  *         the user can pick a note whose data URL is returned back to the caller.</p>
372  *     <li> <p><b>{ action=android.app.action.GET_CONTENT
373  *          type=vnd.android.cursor.item/vnd.google.note }</b>
374  *         is similar to the pick action, but allows the caller to specify the
375  *         kind of data they want back so that the system can find the appropriate
376  *         activity to pick something of that data type.</p>
377  * </ul>
378  *
379  * <p>The second activity,
380  * <code>com.android.notepad.NoteEditor</code>, shows the user a single
381  * note entry and allows them to edit it.  It can do two things as described
382  * by its two intent templates:
383  * <ol>
384  * <li><pre>
385  * &lt;intent-filter android:label="@string/resolve_edit"&gt;
386  *     &lt;action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /&gt;
387  *     &lt;action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /&gt;
388  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
389  *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
390  * &lt;/intent-filter&gt;</pre>
391  * <p>The first, primary, purpose of this activity is to let the user interact
392  * with a single note, as decribed by the MIME type
393  * <code>vnd.android.cursor.item/vnd.google.note</code>.  The activity can
394  * either VIEW a note or allow the user to EDIT it.  Again we support the
395  * DEFAULT category to allow the activity to be launched without explicitly
396  * specifying its component.</p>
397  * <li><pre>
398  * &lt;intent-filter&gt;
399  *     &lt;action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /&gt;
400  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
401  *     &lt;data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /&gt;
402  * &lt;/intent-filter&gt;</pre>
403  * <p>The secondary use of this activity is to insert a new note entry into
404  * an existing directory of notes.  This is used when the user creates a new
405  * note: the INSERT action is executed on the directory of notes, causing
406  * this activity to run and have the user create the new note data which
407  * it then adds to the content provider.</p>
408  * </ol>
409  *
410  * <p>Given these capabilities, the following intents will resolve to the
411  * NoteEditor activity:</p>
412  *
413  * <ul>
414  *     <li> <p><b>{ action=android.intent.action.VIEW
415  *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
416  *         shows the user the content of note <var>{ID}</var>.</p>
417  *     <li> <p><b>{ action=android.app.action.EDIT
418  *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
419  *         allows the user to edit the content of note <var>{ID}</var>.</p>
420  *     <li> <p><b>{ action=android.app.action.INSERT
421  *          data=content://com.google.provider.NotePad/notes }</b>
422  *         creates a new, empty note in the notes list at
423  *         "content://com.google.provider.NotePad/notes"
424  *         and allows the user to edit it.  If they keep their changes, the URI
425  *         of the newly created note is returned to the caller.</p>
426  * </ul>
427  *
428  * <p>The last activity,
429  * <code>com.android.notepad.TitleEditor</code>, allows the user to
430  * edit the title of a note.  This could be implemented as a class that the
431  * application directly invokes (by explicitly setting its component in
432  * the Intent), but here we show a way you can publish alternative
433  * operations on existing data:</p>
434  *
435  * <pre>
436  * &lt;intent-filter android:label="@string/resolve_title"&gt;
437  *     &lt;action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /&gt;
438  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
439  *     &lt;category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /&gt;
440  *     &lt;category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /&gt;
441  *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
442  * &lt;/intent-filter&gt;</pre>
443  *
444  * <p>In the single intent template here, we
445  * have created our own private action called
446  * <code>com.android.notepad.action.EDIT_TITLE</code> which means to
447  * edit the title of a note.  It must be invoked on a specific note
448  * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous
449  * view and edit actions, but here displays and edits the title contained
450  * in the note data.
451  *
452  * <p>In addition to supporting the default category as usual, our title editor
453  * also supports two other standard categories: ALTERNATIVE and
454  * SELECTED_ALTERNATIVE.  Implementing
455  * these categories allows others to find the special action it provides
456  * without directly knowing about it, through the
457  * {@link android.content.pm.PackageManager#queryIntentActivityOptions} method, or
458  * more often to build dynamic menu items with
459  * {@link android.view.Menu#addIntentOptions}.  Note that in the intent
460  * template here was also supply an explicit name for the template
461  * (via <code>android:label="@string/resolve_title"</code>) to better control
462  * what the user sees when presented with this activity as an alternative
463  * action to the data they are viewing.
464  *
465  * <p>Given these capabilities, the following intent will resolve to the
466  * TitleEditor activity:</p>
467  *
468  * <ul>
469  *     <li> <p><b>{ action=com.android.notepad.action.EDIT_TITLE
470  *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
471  *         displays and allows the user to edit the title associated
472  *         with note <var>{ID}</var>.</p>
473  * </ul>
474  *
475  * <h3>Standard Activity Actions</h3>
476  *
477  * <p>These are the current standard actions that Intent defines for launching
478  * activities (usually through {@link Context#startActivity}.  The most
479  * important, and by far most frequently used, are {@link #ACTION_MAIN} and
480  * {@link #ACTION_EDIT}.
481  *
482  * <ul>
483  *     <li> {@link #ACTION_MAIN}

504  *
505  * <h3>Standard Broadcast Actions</h3>
506  *
507  * <p>These are the current standard actions that Intent defines for receiving
508  * broadcasts (usually through {@link Context#registerReceiver} or a

510  *
511  * <ul>
512  *     <li> {@link #ACTION_TIME_TICK}

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

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

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

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

5231      * <p>The ClipData in an intent is not used for Intent matching or other
5232      * such operations.  Semantically it is like extras, used to transmit
5233      * additional data with the Intent.  The main feature of using this over
5234      * the extras for data is that {@link #FLAG_GRANT_READ_URI_PERMISSION}
5235      * and {@link #FLAG_GRANT_WRITE_URI_PERMISSION} will operate on any URI
5236      * items included in the clip data.  This is useful, in particular, if
5237      * you want to transmit an Intent containing multiple <code>content:</code>
5238      * URIs for which the recipient may not have global permission to access the
5239      * content provider.
5240      *
5241      * <p>If the ClipData contains items that are themselves Intents, any
5242      * grant flags in those Intents will be ignored.  Only the top-level flags
5243      * of the main Intent are respected, and will be applied to all Uri or
5244      * Intent items in the clip (or sub-items of the clip).
5245      *
5246      * <p>The MIME type, label, and icon in the ClipData object are not
5247      * directly used by Intent.  Applications should generally rely on the
5248      * MIME type of the Intent itself, not what it may find in the ClipData.
5249      * A common practice is to construct a ClipData for use with an Intent
5250      * with a MIME type of "*\/*".
