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

283  *

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

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

486  * <ul>
487  *     <li> {@link #ACTION_MAIN}

508  *
509  * <h3>Standard Broadcast Actions</h3>
510  *
511  * <p>These are the current standard actions that Intent defines for receiving
512  * broadcasts (usually through {@link Context#registerReceiver} or a

514  *
515  * <ul>
516  *     <li> {@link #ACTION_TIME_TICK}

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

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

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