47/**
48 * An intent is an abstract description of an operation to be performed.  It
49 * can be used with {@link Context#startActivity(Intent) startActivity} to
50 * launch an {@link android.app.Activity},
51 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to
52 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components,
53 * and {@link android.content.Context#startService} or
54 * {@link android.content.Context#bindService} to communicate with a
55 * background {@link android.app.Service}.
56 *
57 * <p>An Intent provides a facility for performing late runtime binding between
58 * the code in different applications.  Its most significant use is in the
59 * launching of activities, where it can be thought of as the glue between
60 * activities. It is
61 * basically a passive data structure holding an abstract description of an
62 * action to be performed. The primary pieces of information in an intent
63 * are:</p>
64 *
65 * <ul>
66 *   <li> <p><b>action</b> -- The general action to be performed, such as
67 *     {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN},
68 *     etc.</p>
69 *   </li>
70 *   <li> <p><b>data</b> -- The data to operate on, such as a person record
71 *     in the contacts database, expressed as a {@link android.net.Uri}.</p>
72 *   </li>
73 * </ul>
74 *
75 *
76 * <p>Some examples of action/data pairs are:</p>
77 *
78 * <ul>
79 *   <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display
80 *     information about the person whose identifier is "1".</p>
81 *   </li>
82 *   <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display
83 *     the phone dialer with the person filled in.</p>
84 *   </li>
85 *   <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display
86 *     the phone dialer with the given number filled in.  Note how the
87 *     VIEW action does what what is considered the most reasonable thing for
88 *     a particular URI.</p>
89 *   </li>
90 *   <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display
91 *     the phone dialer with the given number filled in.</p>
92 *   </li>
93 *   <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit
94 *     information about the person whose identifier is "1".</p>
95 *   </li>
96 *   <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display
97 *     a list of people, which the user can browse through.  This example is a
98 *     typical top-level entry into the Contacts application, showing you the
99 *     list of people. Selecting a particular person to view would result in a
100 *     new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> }
101 *     being used to start an activity to display that person.</p>
102 *   </li>
103 * </ul>
104 *
105 * <p>In addition to these primary attributes, there are a number of secondary
106 * attributes that you can also include with an intent:</p>
107 *
108 * <ul>
109 *     <li> <p><b>category</b> -- Gives additional information about the action
110 *         to execute.  For example, {@link #CATEGORY_LAUNCHER} means it should
111 *         appear in the Launcher as a top-level application, while
112 *         {@link #CATEGORY_ALTERNATIVE} means it should be included in a list
113 *         of alternative actions the user can perform on a piece of data.</p>
114 *     <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the
115 *         intent data.  Normally the type is inferred from the data itself.
116 *         By setting this attribute, you disable that evaluation and force
117 *         an explicit type.</p>
118 *     <li> <p><b>component</b> -- Specifies an explicit name of a component
119 *         class to use for the intent.  Normally this is determined by looking
120 *         at the other information in the intent (the action, data/type, and
121 *         categories) and matching that with a component that can handle it.
122 *         If this attribute is set then none of the evaluation is performed,
123 *         and this component is used exactly as is.  By specifying this attribute,
124 *         all of the other Intent attributes become optional.</p>
125 *     <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information.
126 *         This can be used to provide extended information to the component.
127 *         For example, if we have a action to send an e-mail message, we could
128 *         also include extra pieces of data here to supply a subject, body,
129 *         etc.</p>
130 * </ul>
131 *
132 * <p>Here are some examples of other operations you can specify as intents
133 * using these additional parameters:</p>
134 *
135 * <ul>
136 *   <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> --
137 *     Launch the home screen.</p>
138 *   </li>
139 *   <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type
140 *     <i>{@link android.provider.Contacts.Phones#CONTENT_URI
141 *     vnd.android.cursor.item/phone}</i></b>
142 *     -- Display the list of people's phone numbers, allowing the user to
143 *     browse through them and pick one and return it to the parent activity.</p>
144 *   </li>
145 *   <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type
146 *     <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b>
147 *     -- Display all pickers for data that can be opened with
148 *     {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()},
149 *     allowing the user to pick one of them and then some data inside of it
150 *     and returning the resulting URI to the caller.  This can be used,
151 *     for example, in an e-mail application to allow the user to pick some
152 *     data to include as an attachment.</p>
153 *   </li>
154 * </ul>
155 *
156 * <p>There are a variety of standard Intent action and category constants
157 * defined in the Intent class, but applications can also define their own.
158 * These strings use java style scoping, to ensure they are unique -- for
159 * example, the standard {@link #ACTION_VIEW} is called
160 * "android.intent.action.VIEW".</p>
161 *
162 * <p>Put together, the set of actions, data types, categories, and extra data
163 * defines a language for the system allowing for the expression of phrases
164 * such as "call john smith's cell".  As applications are added to the system,
165 * they can extend this language by adding new actions, types, and categories, or
166 * they can modify the behavior of existing phrases by supplying their own
167 * activities that handle them.</p>
168 *
169 * <a name="IntentResolution"></a>
170 * <h3>Intent Resolution</h3>
171 *
172 * <p>There are two primary forms of intents you will use.
173 *
174 * <ul>
175 *     <li> <p><b>Explicit Intents</b> have specified a component (via
176 *     {@link #setComponent} or {@link #setClass}), which provides the exact
177 *     class to be run.  Often these will not include any other information,
178 *     simply being a way for an application to launch various internal
179 *     activities it has as the user interacts with the application.
180 *
181 *     <li> <p><b>Implicit Intents</b> have not specified a component;
182 *     instead, they must include enough information for the system to
183 *     determine which of the available components is best to run for that
184 *     intent.
185 * </ul>
186 *
187 * <p>When using implicit intents, given such an arbitrary intent we need to
188 * know what to do with it. This is handled by the process of <em>Intent
189 * resolution</em>, which maps an Intent to an {@link android.app.Activity},
190 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or
191 * more activities/receivers) that can handle it.</p>
192 *
193 * <p>The intent resolution mechanism basically revolves around matching an
194 * Intent against all of the &lt;intent-filter&gt; descriptions in the
195 * installed application packages.  (Plus, in the case of broadcasts, any {@link BroadcastReceiver}
196 * objects explicitly registered with {@link Context#registerReceiver}.)  More
197 * details on this can be found in the documentation on the {@link
198 * IntentFilter} class.</p>
199 *
200 * <p>There are three pieces of information in the Intent that are used for
201 * resolution: the action, type, and category.  Using this information, a query
202 * is done on the {@link PackageManager} for a component that can handle the
203 * intent. The appropriate component is determined based on the intent
204 * information supplied in the <code>AndroidManifest.xml</code> file as
205 * follows:</p>
206 *
207 * <ul>
208 *     <li> <p>The <b>action</b>, if given, must be listed by the component as
209 *         one it handles.</p>
210 *     <li> <p>The <b>type</b> is retrieved from the Intent's data, if not
211 *         already supplied in the Intent.  Like the action, if a type is
212 *         included in the intent (either explicitly or implicitly in its
213 *         data), then this must be listed by the component as one it handles.</p>
214 *     <li> For data that is not a <code>content:</code> URI and where no explicit
215 *         type is included in the Intent, instead the <b>scheme</b> of the
216 *         intent data (such as <code>http:</code> or <code>mailto:</code>) is
217 *         considered. Again like the action, if we are matching a scheme it
218 *         must be listed by the component as one it can handle.
219 *     <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed
220 *         by the activity as categories it handles.  That is, if you include
221 *         the categories {@link #CATEGORY_LAUNCHER} and
222 *         {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components
223 *         with an intent that lists <em>both</em> of those categories.
224 *         Activities will very often need to support the
225 *         {@link #CATEGORY_DEFAULT} so that they can be found by
226 *         {@link Context#startActivity Context.startActivity()}.</p>
227 * </ul>
228 *
229 * <p>For example, consider the Note Pad sample application that
230 * allows user to browse through a list of notes data and view details about
231 * individual items.  Text in italics indicate places were you would replace a
232 * name with one specific to your own package.</p>
233 *

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

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

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

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

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

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

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

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

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

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

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

854     * <p>
855     * Input: {@link #getType} is the desired MIME type to retrieve.  Note
856     * that no URI is supplied in the intent, as there are no constraints on

858     * {@link #CATEGORY_OPENABLE} if you can only accept data that can be
859     * opened as a stream.
