68  * An intent is an abstract description of an operation to be performed.  It
69  * can be used with {@link Context#startActivity(Intent) startActivity} to
70  * launch an {@link android.app.Activity},
71  * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to
72  * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components,
73  * and {@link android.content.Context#startService} or
74  * {@link android.content.Context#bindService} to communicate with a
75  * background {@link android.app.Service}.
76  *
77  * <p>An Intent provides a facility for performing late runtime binding between the code in
78  * different applications. Its most significant use is in the launching of activities, where it
79  * can be thought of as the glue between activities. It is basically a passive data structure
80  * holding an abstract description of an action to be performed.</p>
81  *
82  * <div class="special reference">
83  * <h3>Developer Guides</h3>
84  * <p>For information about how to create and resolve intents, read the
85  * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a>
86  * developer guide.</p>
87  * </div>
88  *
89  * <a name="IntentStructure"></a>
90  * <h3>Intent Structure</h3>
91  * <p>The primary pieces of information in an intent are:</p>
92  *
93  * <ul>
94  *   <li> <p><b>action</b> -- The general action to be performed, such as
95  *     {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN},
96  *     etc.</p>
97  *   </li>
98  *   <li> <p><b>data</b> -- The data to operate on, such as a person record
99  *     in the contacts database, expressed as a {@link android.net.Uri}.</p>
100  *   </li>
101  * </ul>
102  *
103  *
104  * <p>Some examples of action/data pairs are:</p>
105  *
106  * <ul>
107  *   <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display
108  *     information about the person whose identifier is "1".</p>
109  *   </li>
110  *   <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display
111  *     the phone dialer with the person filled in.</p>
112  *   </li>
113  *   <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display
114  *     the phone dialer with the given number filled in.  Note how the
115  *     VIEW action does what what is considered the most reasonable thing for
116  *     a particular URI.</p>
117  *   </li>
118  *   <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display
119  *     the phone dialer with the given number filled in.</p>
120  *   </li>
121  *   <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit
122  *     information about the person whose identifier is "1".</p>
123  *   </li>
124  *   <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display
125  *     a list of people, which the user can browse through.  This example is a
126  *     typical top-level entry into the Contacts application, showing you the
127  *     list of people. Selecting a particular person to view would result in a
128  *     new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> }
129  *     being used to start an activity to display that person.</p>
130  *   </li>
131  * </ul>
132  *
133  * <p>In addition to these primary attributes, there are a number of secondary
134  * attributes that you can also include with an intent:</p>
135  *
136  * <ul>
137  *     <li> <p><b>category</b> -- Gives additional information about the action
138  *         to execute.  For example, {@link #CATEGORY_LAUNCHER} means it should
139  *         appear in the Launcher as a top-level application, while
140  *         {@link #CATEGORY_ALTERNATIVE} means it should be included in a list
141  *         of alternative actions the user can perform on a piece of data.</p>
142  *     <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the
143  *         intent data.  Normally the type is inferred from the data itself.
144  *         By setting this attribute, you disable that evaluation and force
145  *         an explicit type.</p>
146  *     <li> <p><b>component</b> -- Specifies an explicit name of a component
147  *         class to use for the intent.  Normally this is determined by looking
148  *         at the other information in the intent (the action, data/type, and
149  *         categories) and matching that with a component that can handle it.
150  *         If this attribute is set then none of the evaluation is performed,
151  *         and this component is used exactly as is.  By specifying this attribute,
152  *         all of the other Intent attributes become optional.</p>
153  *     <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information.
154  *         This can be used to provide extended information to the component.
155  *         For example, if we have a action to send an e-mail message, we could
156  *         also include extra pieces of data here to supply a subject, body,
157  *         etc.</p>
158  * </ul>
159  *
160  * <p>Here are some examples of other operations you can specify as intents
161  * using these additional parameters:</p>
162  *
163  * <ul>
164  *   <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> --
165  *     Launch the home screen.</p>
166  *   </li>
167  *   <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type
168  *     <i>{@link android.provider.Contacts.Phones#CONTENT_URI
169  *     vnd.android.cursor.item/phone}</i></b>
170  *     -- Display the list of people's phone numbers, allowing the user to
171  *     browse through them and pick one and return it to the parent activity.</p>
172  *   </li>
173  *   <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type
174  *     <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b>
175  *     -- Display all pickers for data that can be opened with
176  *     {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()},
177  *     allowing the user to pick one of them and then some data inside of it
178  *     and returning the resulting URI to the caller.  This can be used,
179  *     for example, in an e-mail application to allow the user to pick some
180  *     data to include as an attachment.</p>
181  *   </li>
182  * </ul>
183  *
184  * <p>There are a variety of standard Intent action and category constants
185  * defined in the Intent class, but applications can also define their own.
186  * These strings use java style scoping, to ensure they are unique -- for
187  * example, the standard {@link #ACTION_VIEW} is called
188  * "android.intent.action.VIEW".</p>
189  *
190  * <p>Put together, the set of actions, data types, categories, and extra data
191  * defines a language for the system allowing for the expression of phrases
192  * such as "call john smith's cell".  As applications are added to the system,
193  * they can extend this language by adding new actions, types, and categories, or
194  * they can modify the behavior of existing phrases by supplying their own
195  * activities that handle them.</p>
196  *
197  * <a name="IntentResolution"></a>
198  * <h3>Intent Resolution</h3>
199  *
200  * <p>There are two primary forms of intents you will use.
201  *
202  * <ul>
203  *     <li> <p><b>Explicit Intents</b> have specified a component (via
204  *     {@link #setComponent} or {@link #setClass}), which provides the exact
205  *     class to be run.  Often these will not include any other information,
206  *     simply being a way for an application to launch various internal
207  *     activities it has as the user interacts with the application.
208  *
209  *     <li> <p><b>Implicit Intents</b> have not specified a component;
210  *     instead, they must include enough information for the system to
211  *     determine which of the available components is best to run for that
212  *     intent.
213  * </ul>
214  *
215  * <p>When using implicit intents, given such an arbitrary intent we need to
216  * know what to do with it. This is handled by the process of <em>Intent
217  * resolution</em>, which maps an Intent to an {@link android.app.Activity},
218  * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or
219  * more activities/receivers) that can handle it.</p>
220  *
221  * <p>The intent resolution mechanism basically revolves around matching an
222  * Intent against all of the &lt;intent-filter&gt; descriptions in the
223  * installed application packages.  (Plus, in the case of broadcasts, any {@link BroadcastReceiver}
224  * objects explicitly registered with {@link Context#registerReceiver}.)  More
225  * details on this can be found in the documentation on the {@link
226  * IntentFilter} class.</p>
227  *
228  * <p>There are three pieces of information in the Intent that are used for
229  * resolution: the action, type, and category.  Using this information, a query
230  * is done on the {@link PackageManager} for a component that can handle the
231  * intent. The appropriate component is determined based on the intent
232  * information supplied in the <code>AndroidManifest.xml</code> file as
233  * follows:</p>
234  *
235  * <ul>
236  *     <li> <p>The <b>action</b>, if given, must be listed by the component as
237  *         one it handles.</p>
238  *     <li> <p>The <b>type</b> is retrieved from the Intent's data, if not
239  *         already supplied in the Intent.  Like the action, if a type is
240  *         included in the intent (either explicitly or implicitly in its
241  *         data), then this must be listed by the component as one it handles.</p>
242  *     <li> For data that is not a <code>content:</code> URI and where no explicit
243  *         type is included in the Intent, instead the <b>scheme</b> of the
244  *         intent data (such as <code>http:</code> or <code>mailto:</code>) is
245  *         considered. Again like the action, if we are matching a scheme it
246  *         must be listed by the component as one it can handle.
247  *     <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed
248  *         by the activity as categories it handles.  That is, if you include
249  *         the categories {@link #CATEGORY_LAUNCHER} and
250  *         {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components
251  *         with an intent that lists <em>both</em> of those categories.
252  *         Activities will very often need to support the
253  *         {@link #CATEGORY_DEFAULT} so that they can be found by
254  *         {@link Context#startActivity Context.startActivity()}.</p>
255  * </ul>
256  *
257  * <p>For example, consider the Note Pad sample application that
258  * allows user to browse through a list of notes data and view details about
259  * individual items.  Text in italics indicate places were you would replace a
260  * name with one specific to your own package.</p>
261  *
262  * <pre> &lt;manifest xmlns:android="http://schemas.android.com/apk/res/android"

296  *

298  *                 &lt;action android:name="android.intent.action.INSERT" /&gt;

301  *             &lt;/intent-filter&gt;
302  *
303  *         &lt;/activity&gt;
304  *
305  *         &lt;activity class=".TitleEditor" android:label="@string/title_edit_title"
306  *                 android:theme="@android:style/Theme.Dialog"&gt;
307  *             &lt;intent-filter android:label="@string/resolve_title"&gt;
308  *                 &lt;action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /&gt;
309  *                 &lt;category android:name="android.intent.category.DEFAULT" /&gt;
310  *                 &lt;category android:name="android.intent.category.ALTERNATIVE" /&gt;
311  *                 &lt;category android:name="android.intent.category.SELECTED_ALTERNATIVE" /&gt;
312  *                 &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
313  *             &lt;/intent-filter&gt;
314  *         &lt;/activity&gt;
315  *
316  *     &lt;/application&gt;
317  * &lt;/manifest&gt;</pre>
318  *
319  * <p>The first activity,
320  * <code>com.android.notepad.NotesList</code>, serves as our main
321  * entry into the app.  It can do three things as described by its three intent
322  * templates:
323  * <ol>
324  * <li><pre>
325  * &lt;intent-filter&gt;
326  *     &lt;action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /&gt;
327  *     &lt;category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /&gt;
328  * &lt;/intent-filter&gt;</pre>
329  * <p>This provides a top-level entry into the NotePad application: the standard
330  * MAIN action is a main entry point (not requiring any other information in
331  * the Intent), and the LAUNCHER category says that this entry point should be
332  * listed in the application launcher.</p>
333  * <li><pre>
334  * &lt;intent-filter&gt;
335  *     &lt;action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /&gt;
336  *     &lt;action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /&gt;
337  *     &lt;action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /&gt;
338  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
339  *     &lt;data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /&gt;
340  * &lt;/intent-filter&gt;</pre>
341  * <p>This declares the things that the activity can do on a directory of
342  * notes.  The type being supported is given with the &lt;type&gt; tag, where
343  * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which
344  * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can
345  * be retrieved which holds our note pad data (<code>vnd.google.note</code>).
346  * The activity allows the user to view or edit the directory of data (via
347  * the VIEW and EDIT actions), or to pick a particular note and return it
348  * to the caller (via the PICK action).  Note also the DEFAULT category
349  * supplied here: this is <em>required</em> for the
350  * {@link Context#startActivity Context.startActivity} method to resolve your
351  * activity when its component name is not explicitly specified.</p>
352  * <li><pre>
353  * &lt;intent-filter&gt;
354  *     &lt;action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /&gt;
355  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
356  *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
357  * &lt;/intent-filter&gt;</pre>
358  * <p>This filter describes the ability return to the caller a note selected by
359  * the user without needing to know where it came from.  The data type
360  * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which
361  * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can
362  * be retrieved which contains our note pad data (<code>vnd.google.note</code>).
363  * The GET_CONTENT action is similar to the PICK action, where the activity
364  * will return to its caller a piece of data selected by the user.  Here,
365  * however, the caller specifies the type of data they desire instead of
366  * the type of data the user will be picking from.</p>
367  * </ol>
368  *
369  * <p>Given these capabilities, the following intents will resolve to the
370  * NotesList activity:</p>
371  *
372  * <ul>
373  *     <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the
374  *         activities that can be used as top-level entry points into an
375  *         application.</p>
376  *     <li> <p><b>{ action=android.app.action.MAIN,
377  *         category=android.app.category.LAUNCHER }</b> is the actual intent
378  *         used by the Launcher to populate its top-level list.</p>
379  *     <li> <p><b>{ action=android.intent.action.VIEW
380  *          data=content://com.google.provider.NotePad/notes }</b>
381  *         displays a list of all the notes under
382  *         "content://com.google.provider.NotePad/notes", which
383  *         the user can browse through and see the details on.</p>
384  *     <li> <p><b>{ action=android.app.action.PICK
385  *          data=content://com.google.provider.NotePad/notes }</b>
386  *         provides a list of the notes under
387  *         "content://com.google.provider.NotePad/notes", from which
388  *         the user can pick a note whose data URL is returned back to the caller.</p>
389  *     <li> <p><b>{ action=android.app.action.GET_CONTENT
390  *          type=vnd.android.cursor.item/vnd.google.note }</b>
391  *         is similar to the pick action, but allows the caller to specify the
392  *         kind of data they want back so that the system can find the appropriate
393  *         activity to pick something of that data type.</p>
394  * </ul>
395  *
396  * <p>The second activity,
397  * <code>com.android.notepad.NoteEditor</code>, shows the user a single
398  * note entry and allows them to edit it.  It can do two things as described
399  * by its two intent templates:
400  * <ol>
401  * <li><pre>
402  * &lt;intent-filter android:label="@string/resolve_edit"&gt;
403  *     &lt;action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /&gt;
404  *     &lt;action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /&gt;
405  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
406  *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
407  * &lt;/intent-filter&gt;</pre>
408  * <p>The first, primary, purpose of this activity is to let the user interact
409  * with a single note, as decribed by the MIME type
410  * <code>vnd.android.cursor.item/vnd.google.note</code>.  The activity can
411  * either VIEW a note or allow the user to EDIT it.  Again we support the
412  * DEFAULT category to allow the activity to be launched without explicitly
413  * specifying its component.</p>
414  * <li><pre>
415  * &lt;intent-filter&gt;
416  *     &lt;action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /&gt;
417  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
418  *     &lt;data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /&gt;
419  * &lt;/intent-filter&gt;</pre>
420  * <p>The secondary use of this activity is to insert a new note entry into
421  * an existing directory of notes.  This is used when the user creates a new
422  * note: the INSERT action is executed on the directory of notes, causing
423  * this activity to run and have the user create the new note data which
424  * it then adds to the content provider.</p>
425  * </ol>
426  *
427  * <p>Given these capabilities, the following intents will resolve to the
428  * NoteEditor activity:</p>
429  *
430  * <ul>
431  *     <li> <p><b>{ action=android.intent.action.VIEW
432  *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
433  *         shows the user the content of note <var>{ID}</var>.</p>
434  *     <li> <p><b>{ action=android.app.action.EDIT
435  *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
436  *         allows the user to edit the content of note <var>{ID}</var>.</p>
437  *     <li> <p><b>{ action=android.app.action.INSERT
438  *          data=content://com.google.provider.NotePad/notes }</b>
439  *         creates a new, empty note in the notes list at
440  *         "content://com.google.provider.NotePad/notes"
441  *         and allows the user to edit it.  If they keep their changes, the URI
442  *         of the newly created note is returned to the caller.</p>
443  * </ul>
444  *
445  * <p>The last activity,
446  * <code>com.android.notepad.TitleEditor</code>, allows the user to
447  * edit the title of a note.  This could be implemented as a class that the
448  * application directly invokes (by explicitly setting its component in
449  * the Intent), but here we show a way you can publish alternative
450  * operations on existing data:</p>
451  *
452  * <pre>
453  * &lt;intent-filter android:label="@string/resolve_title"&gt;
454  *     &lt;action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /&gt;
455  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
456  *     &lt;category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /&gt;
457  *     &lt;category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /&gt;
458  *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
459  * &lt;/intent-filter&gt;</pre>
460  *
461  * <p>In the single intent template here, we
462  * have created our own private action called
463  * <code>com.android.notepad.action.EDIT_TITLE</code> which means to
464  * edit the title of a note.  It must be invoked on a specific note
465  * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous
466  * view and edit actions, but here displays and edits the title contained
467  * in the note data.
468  *
469  * <p>In addition to supporting the default category as usual, our title editor
470  * also supports two other standard categories: ALTERNATIVE and
471  * SELECTED_ALTERNATIVE.  Implementing
472  * these categories allows others to find the special action it provides
473  * without directly knowing about it, through the
474  * {@link android.content.pm.PackageManager#queryIntentActivityOptions} method, or
475  * more often to build dynamic menu items with
476  * {@link android.view.Menu#addIntentOptions}.  Note that in the intent
477  * template here was also supply an explicit name for the template
478  * (via <code>android:label="@string/resolve_title"</code>) to better control
479  * what the user sees when presented with this activity as an alternative
480  * action to the data they are viewing.
481  *
482  * <p>Given these capabilities, the following intent will resolve to the
483  * TitleEditor activity:</p>
484  *
485  * <ul>
486  *     <li> <p><b>{ action=com.android.notepad.action.EDIT_TITLE
487  *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
488  *         displays and allows the user to edit the title associated
489  *         with note <var>{ID}</var>.</p>
490  * </ul>
491  *
492  * <h3>Standard Activity Actions</h3>
493  *
494  * <p>These are the current standard actions that Intent defines for launching
495  * activities (usually through {@link Context#startActivity}.  The most
496  * important, and by far most frequently used, are {@link #ACTION_MAIN} and
497  * {@link #ACTION_EDIT}.
498  *
499  * <ul>
500  *     <li> {@link #ACTION_MAIN}

520  * </ul>
521  *
522  * <h3>Standard Broadcast Actions</h3>
523  *
524  * <p>These are the current standard actions that Intent defines for receiving
525  * broadcasts (usually through {@link Context#registerReceiver} or a

527  *
528  * <ul>
529  *     <li> {@link #ACTION_TIME_TICK}

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

567  * </ul>
568  *

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

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

5610      * URIs for which the recipient may not have global permission to access the
5611      * content provider.
5612      *
5613      * <p>If the ClipData contains items that are themselves Intents, any
