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

274 *             &lt;/intent-filter&gt;
275 *
276 *         &lt;/activity&gt;
277 *
278 *         &lt;activity class=".TitleEditor" android:label="@string/title_edit_title"
279 *                 android:theme="@android:style/Theme.Dialog"&gt;

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

493 * </ul>
494 *
495 * <h3>Standard Broadcast Actions</h3>
496 *
497 * <p>These are the current standard actions that Intent defines for receiving
498 * broadcasts (usually through {@link Context#registerReceiver} or a
499 * &lt;receiver&gt; tag in a manifest).
500 *
501 * <ul>
502 *     <li> {@link #ACTION_TIME_TICK}

513 *     <li> {@link #ACTION_POWER_CONNECTED}
514 *     <li> {@link #ACTION_POWER_DISCONNECTED}
515 *     <li> {@link #ACTION_SHUTDOWN}
516 * </ul>
517 *
518 * <h3>Standard Categories</h3>
519 *
520 * <p>These are the current standard categories that can be used to further
521 * clarify an Intent via {@link #addCategory}.
522 *
523 * <ul>
524 *     <li> {@link #CATEGORY_DEFAULT}
525 *     <li> {@link #CATEGORY_BROWSABLE}
526 *     <li> {@link #CATEGORY_TAB}
527 *     <li> {@link #CATEGORY_ALTERNATIVE}
528 *     <li> {@link #CATEGORY_SELECTED_ALTERNATIVE}
529 *     <li> {@link #CATEGORY_LAUNCHER}

534 *     <li> {@link #CATEGORY_CAR_DOCK}
535 *     <li> {@link #CATEGORY_DESK_DOCK}
536 * </ul>
537 *
538 * <h3>Standard Extra Data</h3>
539 *
540 * <p>These are the current standard fields that can be used as extra data via

571 * </ul>
572 *
573 * <h3>Flags</h3>
574 *
575 * <p>These are the possible flags that can be used in the Intent via

783     * it is when the user clicks on a "mailto:" link.  They would naturally
784     * expect to go directly to their mail app, so startActivity() should be

788     * <p>
789     * In contrast, if the user is selecting a menu item to send a picture

791     * may want to do at this point: send it through e-mail, upload it to a

830     * create the data as it runs (for example taking a picture or recording a

839     * <p>
840     * You may also be interested in any of a set of types of content the user
841     * can pick.  For example, an e-mail application that wants to allow the
842     * user to add an attachment to an e-mail message can use this action to
843     * bring up a list of all of the types of content the user can attach.
844     * <p>
845     * In this case, you should wrap the GET_CONTENT intent with a chooser
846     * (through {@link #createChooser}), which will give the proper interface
847     * for the user to pick how to send your data and allow you to specify
848     * a prompt indicating what they are doing.  You will usually specify a
849     * broad MIME type (such as image/* or {@literal *}/*), resulting in a
850     * broad range of content types the user can select from.
851     * <p>
852     * When using such a broad GET_CONTENT action, it is often desireable to

855     * <p>
856     * Input: {@link #getType} is the desired MIME type to retrieve.  Note
857     * that no URI is supplied in the intent, as there are no constraints on
858     * where the returned data originally comes from.  You may also include the
859     * {@link #CATEGORY_OPENABLE} if you can only accept data that can be
860     * opened as a stream.
