An Intent provides a facility for performing late runtime binding between the code in * different applications. Its most significant use is in the launching of activities, where it * can be thought of as the glue between activities. It is basically a passive data structure * holding an abstract description of an action to be performed.
* *For information about how to create and resolve intents, read the * Intents and Intent Filters * developer guide.
*The primary pieces of information in an intent are:
* *action -- The general action to be performed, such as * {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN}, * etc.
*data -- The data to operate on, such as a person record * in the contacts database, expressed as a {@link android.net.Uri}.
*Some examples of action/data pairs are:
* *{@link #ACTION_VIEW} content://contacts/people/1 -- Display * information about the person whose identifier is "1".
*{@link #ACTION_DIAL} content://contacts/people/1 -- Display * the phone dialer with the person filled in.
*{@link #ACTION_VIEW} tel:123 -- Display * the phone dialer with the given number filled in. Note how the * VIEW action does what what is considered the most reasonable thing for * a particular URI.
*{@link #ACTION_DIAL} tel:123 -- Display * the phone dialer with the given number filled in.
*{@link #ACTION_EDIT} content://contacts/people/1 -- Edit * information about the person whose identifier is "1".
*{@link #ACTION_VIEW} content://contacts/people/ -- Display * a list of people, which the user can browse through. This example is a * typical top-level entry into the Contacts application, showing you the * list of people. Selecting a particular person to view would result in a * new intent { {@link #ACTION_VIEW} content://contacts/N } * being used to start an activity to display that person.
*In addition to these primary attributes, there are a number of secondary * attributes that you can also include with an intent:
* *category -- Gives additional information about the action * to execute. For example, {@link #CATEGORY_LAUNCHER} means it should * appear in the Launcher as a top-level application, while * {@link #CATEGORY_ALTERNATIVE} means it should be included in a list * of alternative actions the user can perform on a piece of data.
*type -- Specifies an explicit type (a MIME type) of the * intent data. Normally the type is inferred from the data itself. * By setting this attribute, you disable that evaluation and force * an explicit type.
*component -- Specifies an explicit name of a component * class to use for the intent. Normally this is determined by looking * at the other information in the intent (the action, data/type, and * categories) and matching that with a component that can handle it. * If this attribute is set then none of the evaluation is performed, * and this component is used exactly as is. By specifying this attribute, * all of the other Intent attributes become optional.
*extras -- This is a {@link Bundle} of any additional information. * This can be used to provide extended information to the component. * For example, if we have a action to send an e-mail message, we could * also include extra pieces of data here to supply a subject, body, * etc.
*Here are some examples of other operations you can specify as intents * using these additional parameters:
* *{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME} -- * Launch the home screen.
*{@link #ACTION_GET_CONTENT} with MIME type * {@link android.provider.Contacts.Phones#CONTENT_URI * vnd.android.cursor.item/phone} * -- Display the list of people's phone numbers, allowing the user to * browse through them and pick one and return it to the parent activity.
*{@link #ACTION_GET_CONTENT} with MIME type * *{@literal /}* and category {@link #CATEGORY_OPENABLE} * -- Display all pickers for data that can be opened with * {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()}, * allowing the user to pick one of them and then some data inside of it * and returning the resulting URI to the caller. This can be used, * for example, in an e-mail application to allow the user to pick some * data to include as an attachment.
*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.
* * *There are two primary forms of intents you will use. * *
Explicit Intents have specified a component (via * {@link #setComponent} or {@link #setClass}), which provides the exact * class to be run. Often these will not include any other information, * simply being a way for an application to launch various internal * activities it has as the user interacts with the application. * *
Implicit Intents have not specified a component; * instead, they must include enough information for the system to * determine which of the available components is best to run for that * intent. *
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:
The action, if given, must be listed by the component as * one it handles.
*The type is retrieved from the Intent's data, if not * already supplied in the Intent. Like the action, if a type is * included in the intent (either explicitly or implicitly in its * data), then this must be listed by the component as one it handles.
*content: URI and where no explicit
* type is included in the Intent, instead the scheme of the
* intent data (such as http: or mailto:) is
* considered. Again like the action, if we are matching a scheme it
* must be listed by the component as one it can handle.
* The categories, if supplied, must all be listed * by the activity as categories it handles. That is, if you include * the categories {@link #CATEGORY_LAUNCHER} and * {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components * with an intent that lists both of those categories. * Activities will very often need to support the * {@link #CATEGORY_DEFAULT} so that they can be found by * {@link Context#startActivity Context.startActivity()}.
*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.
* *<manifest xmlns:android="http://schemas.android.com/apk/res/android" * package="com.android.notepad"> * <application android:icon="@drawable/app_notes" * android:label="@string/app_name"> * * <provider class=".NotePadProvider" * android:authorities="com.google.provider.NotePad" /> * * <activity class=".NotesList" android:label="@string/title_notes_list"> * <intent-filter> * <action android:name="android.intent.action.MAIN" /> * <category android:name="android.intent.category.LAUNCHER" /> * </intent-filter> * <intent-filter> * <action android:name="android.intent.action.VIEW" /> * <action android:name="android.intent.action.EDIT" /> * <action android:name="android.intent.action.PICK" /> * <category android:name="android.intent.category.DEFAULT" /> * <data android:mimeType="vnd.android.cursor.dir/vnd.google.note" /> * </intent-filter> * <intent-filter> * <action android:name="android.intent.action.GET_CONTENT" /> * <category android:name="android.intent.category.DEFAULT" /> * <data android:mimeType="vnd.android.cursor.item/vnd.google.note" /> * </intent-filter> * </activity> * * <activity class=".NoteEditor" android:label="@string/title_note"> * <intent-filter android:label="@string/resolve_edit"> * <action android:name="android.intent.action.VIEW" /> * <action android:name="android.intent.action.EDIT" /> * <category android:name="android.intent.category.DEFAULT" /> * <data android:mimeType="vnd.android.cursor.item/vnd.google.note" /> * </intent-filter> * * <intent-filter> * <action android:name="android.intent.action.INSERT" /> * <category android:name="android.intent.category.DEFAULT" /> * <data android:mimeType="vnd.android.cursor.dir/vnd.google.note" /> * </intent-filter> * * </activity> * * <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" /> * <category android:name="android.intent.category.ALTERNATIVE" /> * <category android:name="android.intent.category.SELECTED_ALTERNATIVE" /> * <data android:mimeType="vnd.android.cursor.item/vnd.google.note" /> * </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:
*
* <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.
*
* <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.
* <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:
* *{ action=android.app.action.MAIN } matches all of the * activities that can be used as top-level entry points into an * application.
*{ action=android.app.action.MAIN, * category=android.app.category.LAUNCHER } is the actual intent * used by the Launcher to populate its top-level list.
*{ action=android.intent.action.VIEW * data=content://com.google.provider.NotePad/notes } * displays a list of all the notes under * "content://com.google.provider.NotePad/notes", which * the user can browse through and see the details on.
*{ action=android.app.action.PICK * data=content://com.google.provider.NotePad/notes } * provides a list of the notes under * "content://com.google.provider.NotePad/notes", from which * the user can pick a note whose data URL is returned back to the caller.
*{ action=android.app.action.GET_CONTENT * type=vnd.android.cursor.item/vnd.google.note } * is similar to the pick action, but allows the caller to specify the * kind of data they want back so that the system can find the appropriate * activity to pick something of that data type.
*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:
*
* <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.
* <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:
* *{ action=android.intent.action.VIEW * data=content://com.google.provider.NotePad/notes/{ID} } * shows the user the content of note {ID}.
*{ action=android.app.action.EDIT * data=content://com.google.provider.NotePad/notes/{ID} } * allows the user to edit the content of note {ID}.
*{ action=android.app.action.INSERT * data=content://com.google.provider.NotePad/notes } * creates a new, empty note in the notes list at * "content://com.google.provider.NotePad/notes" * and allows the user to edit it. If they keep their changes, the URI * of the newly created note is returned to the caller.
*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:
* *{ action=com.android.notepad.action.EDIT_TITLE * data=content://com.google.provider.NotePad/notes/{ID} } * displays and allows the user to edit the title associated * with note {ID}.
*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}. * *
These are the current standard actions that Intent defines for receiving * broadcasts (usually through {@link Context#registerReceiver} or a * <receiver> tag in a manifest). * *
These are the current standard categories that can be used to further * clarify an Intent via {@link #addCategory}. * *
These are the current standard fields that can be used as extra data via * {@link #putExtra}. * *
These are the possible flags that can be used in the Intent via * {@link #setFlags} and {@link #addFlags}.

* If the caller can handle multiple returned items (the user performing * multiple selection), then it can specify {@link #EXTRA_ALLOW_MULTIPLE} * to indicate this. *
* Input: {@link #getType} is the desired MIME type to retrieve. Note * that no URI is supplied in the intent, as there are no constraints on * where the returned data originally comes from. You may also include the * {@link #CATEGORY_OPENABLE} if you can only accept data that can be * opened as a stream. You may use {@link #EXTRA_LOCAL_ONLY} to limit content * selection to local data.
