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

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

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

968 * Activity Action: Allow the user to select a particular kind of data and
969 * return it. This is different than {@link #ACTION_PICK} in that here we
970 * just say what kind of data is desired, not a URI of existing data from
971 * which the user can pick. An ACTION_GET_CONTENT could allow the user to
972 * create the data as it runs (for example taking a picture or recording a
973 * sound), let them browse over the web and download the desired data,
976 * There are two main ways to use this action: if you want a specific kind
977 * of data, such as a person contact, you set the MIME type to the kind of
978 * data you want and launch it with {@link Context#startActivity(Intent)}.
979 * The system will then launch the best application to select that kind
982 * You may also be interested in any of a set of types of content the user
983 * can pick. For example, an e-mail application that wants to allow the
984 * user to add an attachment to an e-mail message can use this action to
985 * bring up a list of all of the types of content the user can attach.
987 * In this case, you should wrap the GET_CONTENT intent with a chooser
988 * (through {@link #createChooser}), which will give the proper interface
989 * for the user to pick how to send your data and allow you to specify
990 * a prompt indicating what they are doing. You will usually specify a
991 * broad MIME type (such as image/* or {@literal *}/*), resulting in a
992 * broad range of content types the user can select from.
994 * When using such a broad GET_CONTENT action, it is often desirable to
995 * only pick from data that can be represented as a stream. This is
996 * accomplished by requiring the {@link #CATEGORY_OPENABLE} in the Intent.
998 * Callers can optionally specify {@link #EXTRA_LOCAL_ONLY} to request that
999 * the launched content chooser only returns results representing data that
1000 * is locally available on the device. For example, if this extra is set
1001 * to true then an image picker should not show any pictures that are available
1002 * from a remote server but not already on the local device (thus requiring
1003 * they be downloaded when opened).
1005 * If the caller can handle multiple returned items (the user performing
1006 * multiple selection), then it can specify {@link #EXTRA_ALLOW_MULTIPLE}
1009 * Input: {@link #getType} is the desired MIME type to retrieve. Note
1010 * that no URI is supplied in the intent, as there are no constraints on
1011 * where the returned data originally comes from. You may also include the
1012 * {@link #CATEGORY_OPENABLE} if you can only accept data that can be
1013 * opened as a stream. You may use {@link #EXTRA_LOCAL_ONLY} to limit content
1014 * selection to local data. You may use {@link #EXTRA_ALLOW_MULTIPLE} to
1015 * allow the user to select multiple items.

4462 * <p>The use of the activity attribute form of this,

4464 * preferred over the Intent flag described here. The attribute form allows the

4669 * <pre class="prettyprint">
4670 * android-app://{package_id}[/{scheme}[/{host}[/{path}]]][#Intent;{...}]</pre>
4672 * <p>In this scheme, only the <code>package_id</code> is required. If you include a host,
4673 * you must also include a scheme; including a path also requires both a host and a scheme.
