71  * An intent is an abstract description of an operation to be performed.  It
72  * can be used with {@link Context#startActivity(Intent) startActivity} to
73  * launch an {@link android.app.Activity},
74  * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to
75  * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components,
76  * and {@link android.content.Context#startService} or
77  * {@link android.content.Context#bindService} to communicate with a
78  * background {@link android.app.Service}.
79  *
80  * <p>An Intent provides a facility for performing late runtime binding between the code in
81  * different applications. Its most significant use is in the launching of activities, where it
82  * can be thought of as the glue between activities. It is basically a passive data structure
83  * holding an abstract description of an action to be performed.</p>
84  *
85  * <div class="special reference">
86  * <h3>Developer Guides</h3>
87  * <p>For information about how to create and resolve intents, read the
88  * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a>
89  * developer guide.</p>
90  * </div>
91  *
92  * <a name="IntentStructure"></a>
93  * <h3>Intent Structure</h3>
94  * <p>The primary pieces of information in an intent are:</p>
95  *
96  * <ul>
97  *   <li> <p><b>action</b> -- The general action to be performed, such as
98  *     {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN},
99  *     etc.</p>
100  *   </li>
101  *   <li> <p><b>data</b> -- The data to operate on, such as a person record
102  *     in the contacts database, expressed as a {@link android.net.Uri}.</p>
103  *   </li>
104  * </ul>
105  *
106  *
107  * <p>Some examples of action/data pairs are:</p>
108  *
109  * <ul>
110  *   <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display
111  *     information about the person whose identifier is "1".</p>
112  *   </li>
113  *   <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display
114  *     the phone dialer with the person filled in.</p>
115  *   </li>
116  *   <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display
117  *     the phone dialer with the given number filled in.  Note how the
118  *     VIEW action does what what is considered the most reasonable thing for
119  *     a particular URI.</p>
120  *   </li>
121  *   <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display
122  *     the phone dialer with the given number filled in.</p>
123  *   </li>
124  *   <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit
125  *     information about the person whose identifier is "1".</p>
126  *   </li>
127  *   <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display
128  *     a list of people, which the user can browse through.  This example is a
129  *     typical top-level entry into the Contacts application, showing you the
130  *     list of people. Selecting a particular person to view would result in a
131  *     new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> }
132  *     being used to start an activity to display that person.</p>
133  *   </li>
134  * </ul>
135  *
136  * <p>In addition to these primary attributes, there are a number of secondary
137  * attributes that you can also include with an intent:</p>
138  *
139  * <ul>
140  *     <li> <p><b>category</b> -- Gives additional information about the action
141  *         to execute.  For example, {@link #CATEGORY_LAUNCHER} means it should
142  *         appear in the Launcher as a top-level application, while
143  *         {@link #CATEGORY_ALTERNATIVE} means it should be included in a list
144  *         of alternative actions the user can perform on a piece of data.</p>
145  *     <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the
146  *         intent data.  Normally the type is inferred from the data itself.
147  *         By setting this attribute, you disable that evaluation and force
148  *         an explicit type.</p>
149  *     <li> <p><b>component</b> -- Specifies an explicit name of a component
150  *         class to use for the intent.  Normally this is determined by looking
151  *         at the other information in the intent (the action, data/type, and
152  *         categories) and matching that with a component that can handle it.
153  *         If this attribute is set then none of the evaluation is performed,
154  *         and this component is used exactly as is.  By specifying this attribute,
155  *         all of the other Intent attributes become optional.</p>
156  *     <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information.
157  *         This can be used to provide extended information to the component.
158  *         For example, if we have a action to send an e-mail message, we could
159  *         also include extra pieces of data here to supply a subject, body,
160  *         etc.</p>
161  * </ul>
162  *
163  * <p>Here are some examples of other operations you can specify as intents
164  * using these additional parameters:</p>
165  *
166  * <ul>
167  *   <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> --
168  *     Launch the home screen.</p>
169  *   </li>
170  *   <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type
171  *     <i>{@link android.provider.Contacts.Phones#CONTENT_URI
172  *     vnd.android.cursor.item/phone}</i></b>
173  *     -- Display the list of people's phone numbers, allowing the user to
174  *     browse through them and pick one and return it to the parent activity.</p>
175  *   </li>
176  *   <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type
177  *     <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b>
178  *     -- Display all pickers for data that can be opened with
179  *     {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()},
180  *     allowing the user to pick one of them and then some data inside of it
181  *     and returning the resulting URI to the caller.  This can be used,
182  *     for example, in an e-mail application to allow the user to pick some
183  *     data to include as an attachment.</p>
184  *   </li>
185  * </ul>
186  *
187  * <p>There are a variety of standard Intent action and category constants
188  * defined in the Intent class, but applications can also define their own.
189  * These strings use java style scoping, to ensure they are unique -- for
190  * example, the standard {@link #ACTION_VIEW} is called
191  * "android.intent.action.VIEW".</p>
192  *
193  * <p>Put together, the set of actions, data types, categories, and extra data
194  * defines a language for the system allowing for the expression of phrases
195  * such as "call john smith's cell".  As applications are added to the system,
196  * they can extend this language by adding new actions, types, and categories, or
197  * they can modify the behavior of existing phrases by supplying their own
198  * activities that handle them.</p>
199  *
200  * <a name="IntentResolution"></a>
201  * <h3>Intent Resolution</h3>
202  *
203  * <p>There are two primary forms of intents you will use.
204  *
205  * <ul>
206  *     <li> <p><b>Explicit Intents</b> have specified a component (via
207  *     {@link #setComponent} or {@link #setClass}), which provides the exact
208  *     class to be run.  Often these will not include any other information,
209  *     simply being a way for an application to launch various internal
210  *     activities it has as the user interacts with the application.
211  *
212  *     <li> <p><b>Implicit Intents</b> have not specified a component;
213  *     instead, they must include enough information for the system to
214  *     determine which of the available components is best to run for that
215  *     intent.
216  * </ul>
217  *
218  * <p>When using implicit intents, given such an arbitrary intent we need to
219  * know what to do with it. This is handled by the process of <em>Intent
220  * resolution</em>, which maps an Intent to an {@link android.app.Activity},
221  * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or
222  * more activities/receivers) that can handle it.</p>
223  *
224  * <p>The intent resolution mechanism basically revolves around matching an
225  * Intent against all of the &lt;intent-filter&gt; descriptions in the
226  * installed application packages.  (Plus, in the case of broadcasts, any {@link BroadcastReceiver}
227  * objects explicitly registered with {@link Context#registerReceiver}.)  More
228  * details on this can be found in the documentation on the {@link
229  * IntentFilter} class.</p>
230  *
231  * <p>There are three pieces of information in the Intent that are used for
232  * resolution: the action, type, and category.  Using this information, a query
233  * is done on the {@link PackageManager} for a component that can handle the
234  * intent. The appropriate component is determined based on the intent
235  * information supplied in the <code>AndroidManifest.xml</code> file as
236  * follows:</p>
237  *
238  * <ul>
239  *     <li> <p>The <b>action</b>, if given, must be listed by the component as
240  *         one it handles.</p>
241  *     <li> <p>The <b>type</b> is retrieved from the Intent's data, if not
242  *         already supplied in the Intent.  Like the action, if a type is
243  *         included in the intent (either explicitly or implicitly in its
244  *         data), then this must be listed by the component as one it handles.</p>
245  *     <li> For data that is not a <code>content:</code> URI and where no explicit
246  *         type is included in the Intent, instead the <b>scheme</b> of the
247  *         intent data (such as <code>http:</code> or <code>mailto:</code>) is
248  *         considered. Again like the action, if we are matching a scheme it
249  *         must be listed by the component as one it can handle.
250  *     <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed
251  *         by the activity as categories it handles.  That is, if you include
252  *         the categories {@link #CATEGORY_LAUNCHER} and
253  *         {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components
254  *         with an intent that lists <em>both</em> of those categories.
255  *         Activities will very often need to support the
256  *         {@link #CATEGORY_DEFAULT} so that they can be found by
257  *         {@link Context#startActivity Context.startActivity()}.</p>
258  * </ul>
259  *
260  * <p>For example, consider the Note Pad sample application that
261  * allows user to browse through a list of notes data and view details about
262  * individual items.  Text in italics indicate places were you would replace a
263  * name with one specific to your own package.</p>
264  *
265  * <pre> &lt;manifest xmlns:android="http://schemas.android.com/apk/res/android"

299  *

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

304  *             &lt;/intent-filter&gt;
305  *
306  *         &lt;/activity&gt;
307  *
308  *         &lt;activity class=".TitleEditor" android:label="@string/title_edit_title"
309  *                 android:theme="@android:style/Theme.Dialog"&gt;
310  *             &lt;intent-filter android:label="@string/resolve_title"&gt;
311  *                 &lt;action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /&gt;
312  *                 &lt;category android:name="android.intent.category.DEFAULT" /&gt;

316  *             &lt;/intent-filter&gt;
317  *         &lt;/activity&gt;
318  *
319  *     &lt;/application&gt;
320  * &lt;/manifest&gt;</pre>
321  *
322  * <p>The first activity,
323  * <code>com.android.notepad.NotesList</code>, serves as our main
324  * entry into the app.  It can do three things as described by its three intent
325  * templates:
326  * <ol>
327  * <li><pre>
328  * &lt;intent-filter&gt;
329  *     &lt;action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /&gt;
330  *     &lt;category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /&gt;
331  * &lt;/intent-filter&gt;</pre>
332  * <p>This provides a top-level entry into the NotePad application: the standard
333  * MAIN action is a main entry point (not requiring any other information in
334  * the Intent), and the LAUNCHER category says that this entry point should be
335  * listed in the application launcher.</p>
336  * <li><pre>
337  * &lt;intent-filter&gt;
338  *     &lt;action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /&gt;
339  *     &lt;action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /&gt;
340  *     &lt;action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /&gt;
341  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
342  *     &lt;data mimeType:name="vnd.android.cursor.dir/<i>vnd.google.note</i>" /&gt;
343  * &lt;/intent-filter&gt;</pre>
344  * <p>This declares the things that the activity can do on a directory of
345  * notes.  The type being supported is given with the &lt;type&gt; tag, where
346  * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which
347  * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can
348  * be retrieved which holds our note pad data (<code>vnd.google.note</code>).
349  * The activity allows the user to view or edit the directory of data (via
350  * the VIEW and EDIT actions), or to pick a particular note and return it
351  * to the caller (via the PICK action).  Note also the DEFAULT category
352  * supplied here: this is <em>required</em> for the
353  * {@link Context#startActivity Context.startActivity} method to resolve your
354  * activity when its component name is not explicitly specified.</p>
355  * <li><pre>
356  * &lt;intent-filter&gt;
357  *     &lt;action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /&gt;
358  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
359  *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
360  * &lt;/intent-filter&gt;</pre>
361  * <p>This filter describes the ability return to the caller a note selected by
362  * the user without needing to know where it came from.  The data type
363  * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which
364  * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can
365  * be retrieved which contains our note pad data (<code>vnd.google.note</code>).
366  * The GET_CONTENT action is similar to the PICK action, where the activity
367  * will return to its caller a piece of data selected by the user.  Here,
368  * however, the caller specifies the type of data they desire instead of
369  * the type of data the user will be picking from.</p>
370  * </ol>
371  *
372  * <p>Given these capabilities, the following intents will resolve to the
373  * NotesList activity:</p>
374  *
375  * <ul>
376  *     <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the
377  *         activities that can be used as top-level entry points into an
378  *         application.</p>
379  *     <li> <p><b>{ action=android.app.action.MAIN,
380  *         category=android.app.category.LAUNCHER }</b> is the actual intent
381  *         used by the Launcher to populate its top-level list.</p>
382  *     <li> <p><b>{ action=android.intent.action.VIEW
383  *          data=content://com.google.provider.NotePad/notes }</b>
384  *         displays a list of all the notes under
385  *         "content://com.google.provider.NotePad/notes", which
386  *         the user can browse through and see the details on.</p>
387  *     <li> <p><b>{ action=android.app.action.PICK
388  *          data=content://com.google.provider.NotePad/notes }</b>
389  *         provides a list of the notes under
390  *         "content://com.google.provider.NotePad/notes", from which
391  *         the user can pick a note whose data URL is returned back to the caller.</p>
392  *     <li> <p><b>{ action=android.app.action.GET_CONTENT
393  *          type=vnd.android.cursor.item/vnd.google.note }</b>
394  *         is similar to the pick action, but allows the caller to specify the
395  *         kind of data they want back so that the system can find the appropriate
396  *         activity to pick something of that data type.</p>
397  * </ul>
398  *
399  * <p>The second activity,
400  * <code>com.android.notepad.NoteEditor</code>, shows the user a single
401  * note entry and allows them to edit it.  It can do two things as described
402  * by its two intent templates:
403  * <ol>
404  * <li><pre>
405  * &lt;intent-filter android:label="@string/resolve_edit"&gt;
406  *     &lt;action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /&gt;
407  *     &lt;action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /&gt;
408  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
409  *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
410  * &lt;/intent-filter&gt;</pre>
411  * <p>The first, primary, purpose of this activity is to let the user interact
412  * with a single note, as decribed by the MIME type
413  * <code>vnd.android.cursor.item/vnd.google.note</code>.  The activity can
414  * either VIEW a note or allow the user to EDIT it.  Again we support the
415  * DEFAULT category to allow the activity to be launched without explicitly
416  * specifying its component.</p>
417  * <li><pre>
418  * &lt;intent-filter&gt;
419  *     &lt;action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /&gt;
420  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
421  *     &lt;data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /&gt;
422  * &lt;/intent-filter&gt;</pre>
423  * <p>The secondary use of this activity is to insert a new note entry into
424  * an existing directory of notes.  This is used when the user creates a new
425  * note: the INSERT action is executed on the directory of notes, causing
426  * this activity to run and have the user create the new note data which
427  * it then adds to the content provider.</p>
428  * </ol>
429  *
430  * <p>Given these capabilities, the following intents will resolve to the
431  * NoteEditor activity:</p>
432  *
433  * <ul>
434  *     <li> <p><b>{ action=android.intent.action.VIEW
435  *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
436  *         shows the user the content of note <var>{ID}</var>.</p>
437  *     <li> <p><b>{ action=android.app.action.EDIT
438  *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
439  *         allows the user to edit the content of note <var>{ID}</var>.</p>
440  *     <li> <p><b>{ action=android.app.action.INSERT
441  *          data=content://com.google.provider.NotePad/notes }</b>
442  *         creates a new, empty note in the notes list at
443  *         "content://com.google.provider.NotePad/notes"
444  *         and allows the user to edit it.  If they keep their changes, the URI
445  *         of the newly created note is returned to the caller.</p>
446  * </ul>
447  *
448  * <p>The last activity,
449  * <code>com.android.notepad.TitleEditor</code>, allows the user to
450  * edit the title of a note.  This could be implemented as a class that the
451  * application directly invokes (by explicitly setting its component in
452  * the Intent), but here we show a way you can publish alternative
453  * operations on existing data:</p>
454  *
455  * <pre>
456  * &lt;intent-filter android:label="@string/resolve_title"&gt;
457  *     &lt;action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /&gt;
458  *     &lt;category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /&gt;
459  *     &lt;category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /&gt;
460  *     &lt;category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /&gt;
461  *     &lt;data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /&gt;
462  * &lt;/intent-filter&gt;</pre>
463  *
464  * <p>In the single intent template here, we
465  * have created our own private action called
466  * <code>com.android.notepad.action.EDIT_TITLE</code> which means to
467  * edit the title of a note.  It must be invoked on a specific note
468  * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous
469  * view and edit actions, but here displays and edits the title contained
470  * in the note data.
471  *
472  * <p>In addition to supporting the default category as usual, our title editor
473  * also supports two other standard categories: ALTERNATIVE and
474  * SELECTED_ALTERNATIVE.  Implementing
475  * these categories allows others to find the special action it provides
476  * without directly knowing about it, through the
477  * {@link android.content.pm.PackageManager#queryIntentActivityOptions} method, or
478  * more often to build dynamic menu items with
479  * {@link android.view.Menu#addIntentOptions}.  Note that in the intent
480  * template here was also supply an explicit name for the template
481  * (via <code>android:label="@string/resolve_title"</code>) to better control
482  * what the user sees when presented with this activity as an alternative
483  * action to the data they are viewing.
484  *
485  * <p>Given these capabilities, the following intent will resolve to the
486  * TitleEditor activity:</p>
487  *
488  * <ul>
489  *     <li> <p><b>{ action=com.android.notepad.action.EDIT_TITLE
490  *          data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b>
491  *         displays and allows the user to edit the title associated
492  *         with note <var>{ID}</var>.</p>
493  * </ul>
494  *
495  * <h3>Standard Activity Actions</h3>
496  *
497  * <p>These are the current standard actions that Intent defines for launching
498  * activities (usually through {@link Context#startActivity}.  The most
499  * important, and by far most frequently used, are {@link #ACTION_MAIN} and
500  * {@link #ACTION_EDIT}.
501  *
502  * <ul>
503  *     <li> {@link #ACTION_MAIN}

523  * </ul>
524  *
525  * <h3>Standard Broadcast Actions</h3>
526  *
527  * <p>These are the current standard actions that Intent defines for receiving
528  * broadcasts (usually through {@link Context#registerReceiver} or a

530  *
531  * <ul>
532  *     <li> {@link #ACTION_TIME_TICK}

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

570  * </ul>
571  *

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

950      * create the data as it runs (for example taking a picture or recording a
951      * sound), let them browse over the web and download the desired data,
952      * etc.
953      * <p>
954      * There are two main ways to use this action: if you want a specific kind
955      * of data, such as a person contact, you set the MIME type to the kind of
956      * data you want and launch it with {@link Context#startActivity(Intent)}.
957      * The system will then launch the best application to select that kind
958      * of data for you.
959      * <p>
960      * You may also be interested in any of a set of types of content the user
961      * can pick.  For example, an e-mail application that wants to allow the
962      * user to add an attachment to an e-mail message can use this action to
963      * bring up a list of all of the types of content the user can attach.
964      * <p>
965      * In this case, you should wrap the GET_CONTENT intent with a chooser
966      * (through {@link #createChooser}), which will give the proper interface
967      * for the user to pick how to send your data and allow you to specify
968      * a prompt indicating what they are doing.  You will usually specify a
969      * broad MIME type (such as image/* or {@literal *}/*), resulting in a
970      * broad range of content types the user can select from.
971      * <p>
972      * When using such a broad GET_CONTENT action, it is often desirable to
973      * only pick from data that can be represented as a stream.  This is
974      * accomplished by requiring the {@link #CATEGORY_OPENABLE} in the Intent.
975      * <p>
976      * Callers can optionally specify {@link #EXTRA_LOCAL_ONLY} to request that
977      * the launched content chooser only returns results representing data that
978      * is locally available on the device.  For example, if this extra is set
979      * to true then an image picker should not show any pictures that are available
980      * from a remote server but not already on the local device (thus requiring
981      * they be downloaded when opened).
982      * <p>
983      * If the caller can handle multiple returned items (the user performing
984      * multiple selection), then it can specify {@link #EXTRA_ALLOW_MULTIPLE}
985      * to indicate this.
986      * <p>
987      * Input: {@link #getType} is the desired MIME type to retrieve.  Note
988      * that no URI is supplied in the intent, as there are no constraints on
989      * where the returned data originally comes from.  You may also include the
990      * {@link #CATEGORY_OPENABLE} if you can only accept data that can be
991      * opened as a stream.  You may use {@link #EXTRA_LOCAL_ONLY} to limit content
992      * selection to local data.  You may use {@link #EXTRA_ALLOW_MULTIPLE} to
993      * allow the user to select multiple items.
