It - * can be used with {@link Context#startActivity(Intent) startActivity} to - * launch an {@link android.app.Activity}, - * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to - * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components, - * and {@link android.content.Context#startService} or - * {@link android.content.Context#bindService} to communicate with a - * background {@link android.app.Service}. - * - * <p>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. The primary pieces of information in an intent - * are:</p> - * - * <ul> - * <li> <p><b>action</b> -- The general action to be performed, such as - * {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN}, - * etc.</p> - * </li> - * <li> <p><b>data</b> -- The data to operate on, such as a person record - * in the contacts database, expressed as a {@link android.net.Uri}.</p> - * </li> - * </ul> - * - * - * <p>Some examples of action/data pairs are:</p> - * - * <ul> - * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/1</i></b> -- Display - * information about the person whose identifier is "1".</p> - * </li> - * <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/1</i></b> -- Display - * the phone dialer with the person filled in.</p> - * </li> - * <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- 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.</p> - * </li> - * <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display - * the phone dialer with the given number filled in.</p> - * </li> - * <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/1</i></b> -- Edit - * information about the person whose identifier is "1".</p> - * </li> - * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/</i></b> -- 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 { <b>{@link #ACTION_VIEW} <i>content://contacts/N</i></b> } - * being used to start an activity to display that person.</p> - * </li> - * </ul> - * - * <p>In addition to these primary attributes, there are a number of secondary - * attributes that you can also include with an intent:</p> - * - * <ul> - * <li> <p><b>category</b> -- 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.</p> - * <li> <p><b>type</b> -- 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.</p> - * <li> <p><b>component</b> -- 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.</p> - * <li> <p><b>extras</b> -- 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.</p> - * </ul> - * - * <p>Here are some examples of other operations you can specify as intents - * using these additional parameters:</p> - * - * <ul> - * <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> -- - * Launch the home screen.</p> - * </li> - * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type - * <i>{@link android.provider.Contacts.Phones#CONTENT_URI - * vnd.android.cursor.item/phone}</i></b> - * -- 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.</p> - * </li> - * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type - * <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b> - * -- 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.</p> - * </li> - * </ul> - * - * <p>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.app.action.VIEW".</p> - * - * <p>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.</p> - * - * <a name="IntentResolution"></a> - * <h3>Intent Resolution</h3> - * - * <p>There are two primary forms of intents you will use. - * - * <ul> - * <li> <p><b>Explicit Intents</b> 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. - * - * <li> <p><b>Implicit Intents</b> 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. - * </ul> - * - * <p>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 <em>Intent - * resolution</em>, 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.</p> - * - * <p>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.</p> - * - * <p>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 <code>AndroidManifest.xml</code> file as - * follows:</p> - * - * <ul> - * <li> <p>The <b>action</b>, if given, must be listed by the component as - * one it handles.</p> - * <li> <p>The <b>type</b> 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.</p> - * <li> For data that is not a <code>content:</code> URI and where no explicit - * type is included in the Intent, instead the <b>scheme</b> of the - * intent data (such as <code>http:</code> or <code>mailto:</code>) is - * considered. Again like the action, if we are matching a scheme it - * must be listed by the component as one it can handle. - * <li> <p>The <b>categories</b>, if supplied, must <em>all</em> 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 <em>both</em> 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()}.</p> - * </ul> - * - * <p>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.</p> - * - * <pre> <manifest xmlns:android="http://schemas.android.com/apk/res/android" - * package="<i>com.android.notepad</i>"> - * <application android:icon="@drawable/app_notes" - * android:label="@string/app_name"> - * - * <provider class=".NotePadProvider" - * android:authorities="<i>com.google.provider.NotePad</i>" /> - * - * <activity class=".NotesList" android:label="@string/title_notes_list"> - * <intent-filter> - * <action android:value="android.intent.action.MAIN" /> - * <category android:value="android.intent.category.LAUNCHER" /> - * </intent-filter> - * <intent-filter> - * <action android:value="android.intent.action.VIEW" /> - * <action android:value="android.intent.action.EDIT" /> - * <action android:value="android.intent.action.PICK" /> - * <category android:value="android.intent.category.DEFAULT" /> - * <type android:value="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> - * </intent-filter> - * <intent-filter> - * <action android:value="android.intent.action.GET_CONTENT" /> - * <category android:value="android.intent.category.DEFAULT" /> - * <type android:value="vnd.android.cursor.item/<i>vnd.google.note</i>" /> - * </intent-filter> - * </activity> - * - * <activity class=".NoteEditor" android:label="@string/title_note"> - * <intent-filter android:label="@string/resolve_edit"> - * <action android:value="android.intent.action.VIEW" /> - * <action android:value="android.intent.action.EDIT" /> - * <category android:value="android.intent.category.DEFAULT" /> - * <type android:value="vnd.android.cursor.item/<i>vnd.google.note</i>" /> - * </intent-filter> - * - * <intent-filter> - * <action android:value="android.intent.action.INSERT" /> - * <category android:value="android.intent.category.DEFAULT" /> - * <type android:value="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> - * </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:value="<i>com.android.notepad.action.EDIT_TITLE</i>" /> - * <category android:value="android.intent.category.DEFAULT" /> - * <category android:value="android.intent.category.ALTERNATIVE" /> - * <category android:value="android.intent.category.SELECTED_ALTERNATIVE" /> - * <type android:value="vnd.android.cursor.item/<i>vnd.google.note</i>" /> - * </intent-filter> - * </activity> - * - * </application> - * </manifest></pre> - * - * <p>The first activity, - * <code>com.android.notepad.NotesList</code>, serves as our main - * entry into the app. It can do three things as described by its three intent - * templates: - * <ol> - * <li><pre> - * <intent-filter> - * <action android:value="{@link #ACTION_MAIN android.intent.action.MAIN}" /> - * <category android:value="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /> - * </intent-filter></pre> - * <p>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.</p> - * <li><pre> - * <intent-filter> - * <action android:value="{@link #ACTION_VIEW android.intent.action.VIEW}" /> - * <action android:value="{@link #ACTION_EDIT android.intent.action.EDIT}" /> - * <action android:value="{@link #ACTION_PICK android.intent.action.PICK}" /> - * <category android:value="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> - * <type android:value="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> - * </intent-filter></pre> - * <p>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 - * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which - * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can - * be retrieved which holds our note pad data (<code>vnd.google.note</code>). - * 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 <em>required</em> for the - * {@link Context#startActivity Context.startActivity} method to resolve your - * activity when its component name is not explicitly specified.</p> - * <li><pre> - * <intent-filter> - * <action android:value="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /> - * <category android:value="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> - * <type android:value="vnd.android.cursor.item/<i>vnd.google.note</i>" /> - * </intent-filter></pre> - * <p>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 - * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which - * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can - * be retrieved which contains our note pad data (<code>vnd.google.note</code>). - * 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.</p> - * </ol> - * - * <p>Given these capabilities, the following intents will resolve to the - * NotesList activity:</p> - * - * <ul> - * <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the - * activities that can be used as top-level entry points into an - * application.</p> - * <li> <p><b>{ action=android.app.action.MAIN, - * category=android.app.category.LAUNCHER }</b> is the actual intent - * used by the Launcher to populate its top-level list.</p> - * <li> <p><b>{ action=android.app.action.VIEW - * data=content://com.google.provider.NotePad/notes }</b> - * 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.</p> - * <li> <p><b>{ action=android.app.action.PICK - * data=content://com.google.provider.NotePad/notes }</b> - * 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.</p> - * <li> <p><b>{ action=android.app.action.GET_CONTENT - * type=vnd.android.cursor.item/vnd.google.note }</b> - * 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.</p> - * </ul> - * - * <p>The second activity, - * <code>com.android.notepad.NoteEditor</code>, 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: - * <ol> - * <li><pre> - * <intent-filter android:label="@string/resolve_edit"> - * <action android:value="{@link #ACTION_VIEW android.intent.action.VIEW}" /> - * <action android:value="{@link #ACTION_EDIT android.intent.action.EDIT}" /> - * <category android:value="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> - * <type android:value="vnd.android.cursor.item/<i>vnd.google.note</i>" /> - * </intent-filter></pre> - * <p>The first, primary, purpose of this activity is to let the user interact - * with a single note, as decribed by the MIME type - * <code>vnd.android.cursor.item/vnd.google.note</code>. 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.</p> - * <li><pre> - * <intent-filter> - * <action android:value="{@link #ACTION_INSERT android.intent.action.INSERT}" /> - * <category android:value="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> - * <type android:value="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> - * </intent-filter></pre> - * <p>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.</p> - * </ol> - * - * <p>Given these capabilities, the following intents will resolve to the - * NoteEditor activity:</p> - * - * <ul> - * <li> <p><b>{ action=android.app.action.VIEW - * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> - * shows the user the content of note <var>{ID}</var>.</p> - * <li> <p><b>{ action=android.app.action.EDIT - * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> - * allows the user to edit the content of note <var>{ID}</var>.</p> - * <li> <p><b>{ action=android.app.action.INSERT - * data=content://com.google.provider.NotePad/notes }</b> - * 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.</p> - * </ul> - * - * <p>The last activity, - * <code>com.android.notepad.TitleEditor</code>, 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:</p> - * - * <pre> - * <intent-filter android:label="@string/resolve_title"> - * <action android:value="<i>com.android.notepad.action.EDIT_TITLE</i>" /> - * <category android:value="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> - * <category android:value="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /> - * <category android:value="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /> - * <type android:value="vnd.android.cursor.item/<i>vnd.google.note</i>" /> - * </intent-filter></pre> - * - * <p>In the single intent template here, we - * have created our own private action called - * <code>com.android.notepad.action.EDIT_TITLE</code> which means to - * edit the title of a note. It must be invoked on a specific note - * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous - * view and edit actions, but here displays and edits the title contained - * in the note data. - * - * <p>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 <code>android:label="@string/resolve_title"</code>) to better control - * what the user sees when presented with this activity as an alternative - * action to the data they are viewing. - * - * <p>Given these capabilities, the following intent will resolve to the - * TitleEditor activity:</p> - * - * <ul> - * <li> <p><b>{ action=com.android.notepad.action.EDIT_TITLE - * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> - * displays and allows the user to edit the title associated - * with note <var>{ID}</var>.</p> - * </ul> - * - * <h3>Standard Activity Actions</h3> - * - * <p>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}. - * - * <ul> - * <li> {@link #ACTION_MAIN} - * <li> {@link #ACTION_VIEW} - * <li> {@link #ACTION_ATTACH_DATA} - * <li> {@link #ACTION_EDIT} - * <li> {@link #ACTION_PICK} - * <li> {@link #ACTION_CHOOSER} - * <li> {@link #ACTION_GET_CONTENT} - * <li> {@link #ACTION_DIAL} - * <li> {@link #ACTION_CALL} - * <li> {@link #ACTION_SEND} - * <li> {@link #ACTION_SENDTO} - * <li> {@link #ACTION_ANSWER} - * <li> {@link #ACTION_INSERT} - * <li> {@link #ACTION_DELETE} - * <li> {@link #ACTION_RUN} - * <li> {@link #ACTION_SYNC} - * <li> {@link #ACTION_PICK_ACTIVITY} - * <li> {@link #ACTION_SEARCH} - * <li> {@link #ACTION_WEB_SEARCH} - * <li> {@link #ACTION_FACTORY_TEST} - * </ul> - * - * <h3>Standard Broadcast Actions</h3> - * - * <p>These are the current standard actions that Intent defines for receiving - * broadcasts (usually through {@link Context#registerReceiver} or a - * <receiver> tag in a manifest). - * - * <ul> - * <li> {@link #ACTION_TIME_TICK} - * <li> {@link #ACTION_TIME_CHANGED} - * <li> {@link #ACTION_TIMEZONE_CHANGED} - * <li> {@link #ACTION_BOOT_COMPLETED} - * <li> {@link #ACTION_PACKAGE_ADDED} - * <li> {@link #ACTION_PACKAGE_CHANGED} - * <li> {@link #ACTION_PACKAGE_REMOVED} - * <li> {@link #ACTION_PACKAGE_RESTARTED} - * <li> {@link #ACTION_PACKAGE_DATA_CLEARED} - * <li> {@link #ACTION_UID_REMOVED} - * <li> {@link #ACTION_BATTERY_CHANGED} - * </ul> - * - * <h3>Standard Categories</h3> - * - * <p>These are the current standard categories that can be used to further - * clarify an Intent via {@link #addCategory}. - * - * <ul> - * <li> {@link #CATEGORY_DEFAULT} - * <li> {@link #CATEGORY_BROWSABLE} - * <li> {@link #CATEGORY_TAB} - * <li> {@link #CATEGORY_ALTERNATIVE} - * <li> {@link #CATEGORY_SELECTED_ALTERNATIVE} - * <li> {@link #CATEGORY_LAUNCHER} - * <li> {@link #CATEGORY_HOME} - * <li> {@link #CATEGORY_PREFERENCE} - * <li> {@link #CATEGORY_GADGET} - * <li> {@link #CATEGORY_TEST} - * </ul> - * - * <h3>Standard Extra Data</h3> - * - * <p>These are the current standard fields that can be used as extra data via - * {@link #putExtra}. - * - * <ul> - * <li> {@link #EXTRA_TEMPLATE} - * <li> {@link #EXTRA_INTENT} - * <li> {@link #EXTRA_STREAM} - * <li> {@link #EXTRA_TEXT} - * </ul> - * - * <h3>Flags</h3> - * - * <p>These are the possible flags that can be used in the Intent via - * {@link #setFlags} and {@link #addFlags}.
