An Intent provides a facility for performing late runtime binding between the code in * different applications.

*

Developer Guides

*

For information about how to create and resolve intents, read the * Intents and Intent Filters * developer guide.

*
* * *

Intent Structure

*

The primary pieces of information in an intent are:

* * * * *

Some examples of action/data pairs are:

* * * *

In addition to these primary attributes, there are a number of secondary * attributes that you can also include with an intent:

* * * *

Here are some examples of other operations you can specify as intents * using these additional parameters:

* * * *

There are a variety of standard Intent action and category constants * defined in the Intent class, but applications can also define their own. * These strings use java style scoping, to ensure they are unique -- for * example, the standard {@link #ACTION_VIEW} is called * "android.intent.action.VIEW".

* *

Put together, the set of actions, data types, categories, and extra data * defines a language for the system allowing for the expression of phrases * such as "call john smith's cell". As applications are added to the system, * they can extend this language by adding new actions, types, and categories, or * they can modify the behavior of existing phrases by supplying their own * activities that handle them.

* * *

Intent Resolution

* *

There are two primary forms of intents you will use. * *

* *

When using implicit intents, given such an arbitrary intent we need to * know what to do with it. This is handled by the process of Intent * resolution, which maps an Intent to an {@link android.app.Activity}, * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or * more activities/receivers) that can handle it.

* *

The intent resolution mechanism basically revolves around matching an * Intent against all of the <intent-filter> descriptions in the * installed application packages. (Plus, in the case of broadcasts, any {@link BroadcastReceiver} * objects explicitly registered with {@link Context#registerReceiver}.) More * details on this can be found in the documentation on the {@link * IntentFilter} class.

* *

There are three pieces of information in the Intent that are used for * resolution: the action, type, and category. Using this information, a query * is done on the {@link PackageManager} for a component that can handle the * intent. The appropriate component is determined based on the intent * information supplied in the AndroidManifest.xml file as * follows:

* * * *

For example, consider the Note Pad sample application that * allows user to browse through a list of notes data and view details about * individual items. Text in italics indicate places were you would replace a * name with one specific to your own package.

* *

 *
 *         <activity class=".TitleEditor" android:label="@string/title_edit_title"
 *                 android:theme="@android:style/Theme.Dialog">
 *             <intent-filter android:label="@string/resolve_title">
 *                 <action android:name="com.android.notepad.action.EDIT_TITLE" />
 *                 <category android:name="android.intent.category.DEFAULT" />

 *             </intent-filter>
 *         </activity>
 *
 *     </application>
 * </manifest>
* *

The first activity, * com.android.notepad.NotesList, serves as our main * entry into the app. It can do three things as described by its three intent * templates: *

    * 
  1.  * <intent-filter>
 *     <action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" />
 *     <category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" />
 * </intent-filter>
    *

    This provides a top-level entry into the NotePad application: the standard * MAIN action is a main entry point (not requiring any other information in * the Intent), and the LAUNCHER category says that this entry point should be * listed in the application launcher.

    * 
  2.  * <intent-filter>
 *     <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" />
 *     <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" />
 *     <action android:name="{@link #ACTION_PICK android.intent.action.PICK}" />
 *     <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" />
 *     <data mimeType:name="vnd.android.cursor.dir/vnd.google.note" />
 * </intent-filter>
    *

    This declares the things that the activity can do on a directory of * notes. The type being supported is given with the <type> tag, where * vnd.android.cursor.dir/vnd.google.note is a URI from which * a Cursor of zero or more items (vnd.android.cursor.dir) can * be retrieved which holds our note pad data (vnd.google.note). * The activity allows the user to view or edit the directory of data (via * the VIEW and EDIT actions), or to pick a particular note and return it * to the caller (via the PICK action). Note also the DEFAULT category * supplied here: this is required for the * {@link Context#startActivity Context.startActivity} method to resolve your * activity when its component name is not explicitly specified.

    * 
  3.  * <intent-filter>
 *     <action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" />
 *     <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" />
 *     <data android:mimeType="vnd.android.cursor.item/vnd.google.note" />
 * </intent-filter>
    *

    This filter describes the ability return to the caller a note selected by * the user without needing to know where it came from. The data type * vnd.android.cursor.item/vnd.google.note is a URI from which * a Cursor of exactly one (vnd.android.cursor.item) item can * be retrieved which contains our note pad data (vnd.google.note). * The GET_CONTENT action is similar to the PICK action, where the activity * will return to its caller a piece of data selected by the user. Here, * however, the caller specifies the type of data they desire instead of * the type of data the user will be picking from.

    *
* *

Given these capabilities, the following intents will resolve to the * NotesList activity:

* * * *

The second activity, * com.android.notepad.NoteEditor, shows the user a single * note entry and allows them to edit it. It can do two things as described * by its two intent templates: *

    * 
  1.  * <intent-filter android:label="@string/resolve_edit">
 *     <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" />
 *     <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" />
 *     <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" />
 *     <data android:mimeType="vnd.android.cursor.item/vnd.google.note" />
 * </intent-filter>
    *

    The first, primary, purpose of this activity is to let the user interact * with a single note, as decribed by the MIME type * vnd.android.cursor.item/vnd.google.note. The activity can * either VIEW a note or allow the user to EDIT it. Again we support the * DEFAULT category to allow the activity to be launched without explicitly * specifying its component.

    * 
  2.  * <intent-filter>
 *     <action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" />
 *     <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" />
 *     <data android:mimeType="vnd.android.cursor.dir/vnd.google.note" />
 * </intent-filter>
    *

    The secondary use of this activity is to insert a new note entry into * an existing directory of notes. This is used when the user creates a new * note: the INSERT action is executed on the directory of notes, causing * this activity to run and have the user create the new note data which * it then adds to the content provider.

    *
* *

Given these capabilities, the following intents will resolve to the * NoteEditor activity:

* * * *

The last activity, * com.android.notepad.TitleEditor, allows the user to * edit the title of a note. This could be implemented as a class that the * application directly invokes (by explicitly setting its component in * the Intent), but here we show a way you can publish alternative * operations on existing data:

* * 
 * <intent-filter android:label="@string/resolve_title">
 *     <action android:name="com.android.notepad.action.EDIT_TITLE" />
 *     <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" />
 *     <category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" />
 *     <category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" />
 *     <data android:mimeType="vnd.android.cursor.item/vnd.google.note" />
 * </intent-filter>
* *

In the single intent template here, we * have created our own private action called * com.android.notepad.action.EDIT_TITLE which means to * edit the title of a note. It must be invoked on a specific note * (data type vnd.android.cursor.item/vnd.google.note) like the previous * view and edit actions, but here displays and edits the title contained * in the note data. * *

In addition to supporting the default category as usual, our title editor * also supports two other standard categories: ALTERNATIVE and * SELECTED_ALTERNATIVE. Implementing * these categories allows others to find the special action it provides * without directly knowing about it, through the * {@link android.content.pm.PackageManager#queryIntentActivityOptions} method, or * more often to build dynamic menu items with * {@link android.view.Menu#addIntentOptions}. Note that in the intent * template here was also supply an explicit name for the template * (via android:label="@string/resolve_title") to better control * what the user sees when presented with this activity as an alternative * action to the data they are viewing. * *

Given these capabilities, the following intent will resolve to the * TitleEditor activity:

* * * *

Standard Activity Actions

* *

These are the current standard actions that Intent defines for launching * activities (usually through {@link Context#startActivity}. The most * important, and by far most frequently used, are {@link #ACTION_MAIN} and * {@link #ACTION_EDIT}. * *

* *

Standard Broadcast Actions

* *

These are the current standard actions that Intent defines for receiving * broadcasts (usually through {@link Context#registerReceiver} or a * <receiver> tag in a manifest). * *

* *

Standard Categories

* *

These are the current standard categories that can be used to further * clarify an Intent via {@link #addCategory}. * *

* *

Standard Extra Data

* *

These are the current standard fields that can be used as extra data via * {@link #putExtra}. * *

* *

Flags

* *

These are the possible flags that can be used in the Intent via * {@link #setFlags} and {@link #addFlags}.

* There are two main ways to use this action: if you want an specific kind * of data, such as a person contact, you set the MIME type to the kind of * data you want and launch it with {@link Context#startActivity(Intent)}. * The system will then launch the best application to select that kind * of data for you. *

* You may also be interested in any of a set of types of content the user * can pick. For example, an e-mail application that wants to allow the * user to add an attachment to an e-mail message can use this action to * bring up a list of all of the types of content the user can attach. *
