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

277  *

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

282  *             &lt;/intent-filter&gt;
283  *
284  *         &lt;/activity&gt;
285  *
286  *         &lt;activity class=".TitleEditor" android:label="@string/title_edit_title"
287  *                 android:theme="@android:style/Theme.Dialog"&gt;
288  *             &lt;intent-filter android:label="@string/resolve_title"&gt;
289  *                 &lt;action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /&gt;
290  *                 &lt;category android:name="android.intent.category.DEFAULT" /&gt;
291  *                 &lt;category android:name="android.intent.category.ALTERNATIVE" /&gt;
292  *                 &lt;category android:name="android.intent.category.SELECTED_ALTERNATIVE" /&gt;
293  *                 &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
294  *             &lt;/intent-filter&gt;
295  *         &lt;/activity&gt;
296  *
297  *     &lt;/application&gt;
298  * &lt;/manifest&gt;</pre>
299  *
300  * <p>The first activity,
301  * <code>com.android.notepad.NotesList</code>, serves as our main
302  * entry into the app.  It can do three things as described by its three intent
303  * templates:
304  * <ol>
305  * <li><pre>
306  * &lt;intent-filter&gt;
307  *     &lt;action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /&gt;
308  *     &lt;category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /&gt;
309  * &lt;/intent-filter&gt;</pre>
310  * <p>This provides a top-level entry into the NotePad application: the standard
311  * MAIN action is a main entry point (not requiring any other information in
312  * the Intent), and the LAUNCHER category says that this entry point should be
313  * listed in the application launcher.</p>
314  * <li><pre>
315  * &lt;intent-filter&gt;
316  *     &lt;action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /&gt;
317  *     &lt;action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /&gt;
318  *     &lt;action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /&gt;
319  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
320  *     &lt;data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /&gt;
321  * &lt;/intent-filter&gt;</pre>
322  * <p>This declares the things that the activity can do on a directory of
323  * notes.  The type being supported is given with the &lt;type&gt; tag, where
324  * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which
325  * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can
326  * be retrieved which holds our note pad data (<code>vnd.google.note</code>).
327  * The activity allows the user to view or edit the directory of data (via
328  * the VIEW and EDIT actions), or to pick a particular note and return it
329  * to the caller (via the PICK action).  Note also the DEFAULT category
330  * supplied here: this is <em>required</em> for the
331  * {@link Context#startActivity Context.startActivity} method to resolve your
332  * activity when its component name is not explicitly specified.</p>
333  * <li><pre>
334  * &lt;intent-filter&gt;
335  *     &lt;action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /&gt;
336  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
337  *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
338  * &lt;/intent-filter&gt;</pre>
339  * <p>This filter describes the ability return to the caller a note selected by
340  * the user without needing to know where it came from.  The data type
341  * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which
342  * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can
343  * be retrieved which contains our note pad data (<code>vnd.google.note</code>).
344  * The GET_CONTENT action is similar to the PICK action, where the activity
345  * will return to its caller a piece of data selected by the user.  Here,
346  * however, the caller specifies the type of data they desire instead of
347  * the type of data the user will be picking from.</p>
348  * </ol>
349  *
350  * <p>Given these capabilities, the following intents will resolve to the
351  * NotesList activity:</p>
352  *
353  * <ul>
354  *     <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the
355  *         activities that can be used as top-level entry points into an
356  *         application.</p>
357  *     <li> <p><b>{ action=android.app.action.MAIN,
358  *         category=android.app.category.LAUNCHER }</b> is the actual intent
359  *         used by the Launcher to populate its top-level list.</p>
360  *     <li> <p><b>{ action=android.intent.action.VIEW
361  *          data=content://com.google.provider.NotePad/notes }</b>
362  *         displays a list of all the notes under
363  *         "content://com.google.provider.NotePad/notes", which
364  *         the user can browse through and see the details on.</p>
365  *     <li> <p><b>{ action=android.app.action.PICK
366  *          data=content://com.google.provider.NotePad/notes }</b>
367  *         provides a list of the notes under
368  *         "content://com.google.provider.NotePad/notes", from which
369  *         the user can pick a note whose data URL is returned back to the caller.</p>
370  *     <li> <p><b>{ action=android.app.action.GET_CONTENT
371  *          type=vnd.android.cursor.item/vnd.google.note }</b>
372  *         is similar to the pick action, but allows the caller to specify the
373  *         kind of data they want back so that the system can find the appropriate
374  *         activity to pick something of that data type.</p>
375  * </ul>
376  *
377  * <p>The second activity,
378  * <code>com.android.notepad.NoteEditor</code>, shows the user a single
379  * note entry and allows them to edit it.  It can do two things as described
380  * by its two intent templates:
381  * <ol>
382  * <li><pre>
383  * &lt;intent-filter android:label="@string/resolve_edit"&gt;
384  *     &lt;action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /&gt;
385  *     &lt;action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /&gt;
386  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
387  *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
388  * &lt;/intent-filter&gt;</pre>
389  * <p>The first, primary, purpose of this activity is to let the user interact
390  * with a single note, as decribed by the MIME type
391  * <code>vnd.android.cursor.item/vnd.google.note</code>.  The activity can
392  * either VIEW a note or allow the user to EDIT it.  Again we support the
393  * DEFAULT category to allow the activity to be launched without explicitly
394  * specifying its component.</p>
395  * <li><pre>
396  * &lt;intent-filter&gt;
397  *     &lt;action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /&gt;
398  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
399  *     &lt;data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /&gt;
400  * &lt;/intent-filter&gt;</pre>
401  * <p>The secondary use of this activity is to insert a new note entry into
402  * an existing directory of notes.  This is used when the user creates a new
403  * note: the INSERT action is executed on the directory of notes, causing
404  * this activity to run and have the user create the new note data which
405  * it then adds to the content provider.</p>
406  * </ol>
407  *
408  * <p>Given these capabilities, the following intents will resolve to the
409  * NoteEditor activity:</p>
410  *
411  * <ul>
412  *     <li> <p><b>{ action=android.intent.action.VIEW
413  *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
414  *         shows the user the content of note <var>{ID}</var>.</p>
415  *     <li> <p><b>{ action=android.app.action.EDIT
416  *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
417  *         allows the user to edit the content of note <var>{ID}</var>.</p>
418  *     <li> <p><b>{ action=android.app.action.INSERT
419  *          data=content://com.google.provider.NotePad/notes }</b>
420  *         creates a new, empty note in the notes list at
421  *         "content://com.google.provider.NotePad/notes"
422  *         and allows the user to edit it.  If they keep their changes, the URI
423  *         of the newly created note is returned to the caller.</p>
424  * </ul>
425  *
426  * <p>The last activity,
427  * <code>com.android.notepad.TitleEditor</code>, allows the user to
428  * edit the title of a note.  This could be implemented as a class that the
429  * application directly invokes (by explicitly setting its component in
430  * the Intent), but here we show a way you can publish alternative
431  * operations on existing data:</p>
432  *
433  * <pre>
434  * &lt;intent-filter android:label="@string/resolve_title"&gt;
435  *     &lt;action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /&gt;
436  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
437  *     &lt;category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /&gt;
438  *     &lt;category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /&gt;
439  *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
440  * &lt;/intent-filter&gt;</pre>
441  *
442  * <p>In the single intent template here, we
443  * have created our own private action called
444  * <code>com.android.notepad.action.EDIT_TITLE</code> which means to
445  * edit the title of a note.  It must be invoked on a specific note
446  * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous
447  * view and edit actions, but here displays and edits the title contained
448  * in the note data.
449  *
450  * <p>In addition to supporting the default category as usual, our title editor
451  * also supports two other standard categories: ALTERNATIVE and
452  * SELECTED_ALTERNATIVE.  Implementing
453  * these categories allows others to find the special action it provides
454  * without directly knowing about it, through the
455  * {@link android.content.pm.PackageManager#queryIntentActivityOptions} method, or
456  * more often to build dynamic menu items with
457  * {@link android.view.Menu#addIntentOptions}.  Note that in the intent
458  * template here was also supply an explicit name for the template
459  * (via <code>android:label="@string/resolve_title"</code>) to better control
460  * what the user sees when presented with this activity as an alternative
461  * action to the data they are viewing.
462  *
463  * <p>Given these capabilities, the following intent will resolve to the
464  * TitleEditor activity:</p>
465  *
466  * <ul>
467  *     <li> <p><b>{ action=com.android.notepad.action.EDIT_TITLE
468  *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
469  *         displays and allows the user to edit the title associated
470  *         with note <var>{ID}</var>.</p>
471  * </ul>
472  *
473  * <h3>Standard Activity Actions</h3>
474  *
475  * <p>These are the current standard actions that Intent defines for launching
476  * activities (usually through {@link Context#startActivity}.  The most
477  * important, and by far most frequently used, are {@link #ACTION_MAIN} and
478  * {@link #ACTION_EDIT}.

502  *
503  * <h3>Standard Broadcast Actions</h3>
504  *
505  * <p>These are the current standard actions that Intent defines for receiving
506  * broadcasts (usually through {@link Context#registerReceiver} or a

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

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

842      * just say what kind of data is desired, not a URI of existing data from
843      * which the user can pick.  A ACTION_GET_CONTENT could allow the user to
844      * create the data as it runs (for example taking a picture or recording a

846      * etc.
847      * <p>
848      * There are two main ways to use this action: if you want an specific kind
849      * of data, such as a person contact, you set the MIME type to the kind of
850      * data you want and launch it with {@link Context#startActivity(Intent)}.
851      * The system will then launch the best application to select that kind
852      * of data for you.
853      * <p>
854      * You may also be interested in any of a set of types of content the user
855      * can pick.  For example, an e-mail application that wants to allow the
856      * user to add an attachment to an e-mail message can use this action to
857      * bring up a list of all of the types of content the user can attach.
858      * <p>
859      * In this case, you should wrap the GET_CONTENT intent with a chooser
860      * (through {@link #createChooser}), which will give the proper interface
861      * for the user to pick how to send your data and allow you to specify
862      * a prompt indicating what they are doing.  You will usually specify a
863      * broad MIME type (such as image/* or {@literal *}/*), resulting in a
864      * broad range of content types the user can select from.
865      * <p>
866      * When using such a broad GET_CONTENT action, it is often desireable to
867      * only pick from data that can be represented as a stream.  This is
868      * accomplished by requiring the {@link #CATEGORY_OPENABLE} in the Intent.
869      * <p>
870      * Callers can optionally specify {@link #EXTRA_LOCAL_ONLY} to request that
871      * the launched content chooser only return results representing data that
872      * is locally available on the device.  For example, if this extra is set
873      * to true then an image picker should not show any pictures that are available
874      * from a remote server but not already on the local device (thus requiring
875      * they be downloaded when opened).
876      * <p>
877      * Input: {@link #getType} is the desired MIME type to retrieve.  Note
878      * that no URI is supplied in the intent, as there are no constraints on
879      * where the returned data originally comes from.  You may also include the
880      * {@link #CATEGORY_OPENABLE} if you can only accept data that can be
881      * opened as a stream.  You may use {@link #EXTRA_LOCAL_ONLY} to limit content
882      * selection to local data.
883      * <p>
