/**
 * An intent is an abstract description of an operation to be performed.  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> 

action -- The general action to be performed, such as * {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN}, * etc.</p> * </li> * <li>

data -- 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:

* * <ul> * <li>

{@link #ACTION_VIEW} content://contacts/people/1 -- Display * information about the person whose identifier is "1".</p> * </li> * <li>

{@link #ACTION_DIAL} content://contacts/people/1 -- Display * the phone dialer with the person filled in.</p> * </li> * <li>

{@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.</p> * </li> * <li>

{@link #ACTION_DIAL} tel:123 -- Display * the phone dialer with the given number filled in.</p> * </li> * <li>

{@link #ACTION_EDIT} content://contacts/people/1 -- Edit * information about the person whose identifier is "1".</p> * </li> * <li>

{@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 { <b>{@link #ACTION_VIEW} content://contacts/N } * 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>

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.</p> * <li>

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.</p> * <li>

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.</p> * <li>

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.</p> * </ul> * * <p>Here are some examples of other operations you can specify as intents * using these additional parameters:</p> * * <ul> * <li>

{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME} -- * Launch the home screen.</p> * </li> * <li>

{@link #ACTION_GET_CONTENT} with MIME type * <i>{@link android.provider.Contacts.Phones#CONTENT_URI * vnd.android.cursor.item/phone}</i> * -- 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>

{@link #ACTION_GET_CONTENT} with MIME type * <i>*{@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.</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.intent.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"> * <h3>Intent Resolution * * <p>There are two primary forms of intents you will use. * * <ul> * <li>

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. * * <li>

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. * </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 file as * follows:</p> * * <ul> * <li>

The action, if given, must be listed by the component as * one it handles.</p> * <li>

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.</p> * <li> For data that is not a content: URI and where no explicit * type is included in the Intent, instead the <b>scheme of the * intent data (such as <code>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. * <li>

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 <em>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()}.</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"> * <application android:icon="@drawable/app_notes" * android:label="@string/app_name"> * * <provider class=".NotePadProvider" * android:authorities="<i>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/<i>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/<i>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/<i>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/<i>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="<i>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/<i>vnd.google.note" /> * </intent-filter> * </activity> * * </application> * </manifest></pre> * * <p>The first activity, * <code>com.android.notepad.NotesList, serves as our main * entry into the app. It can do three things as described by its three intent * templates: * <ol> * <li>

 * <intent-filter>
 *     <action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" />
 *     <category android:name="{@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>
 * <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/<i>vnd.google.note" />
 * </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 is a URI from which
 * a Cursor of zero or more items (<code>vnd.android.cursor.dir) can
 * be retrieved which holds our note pad data (<code>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 <em>required for the
 * {@link Context#startActivity Context.startActivity} method to resolve your
 * activity when its component name is not explicitly specified.</p>
 * <li>
 * <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/<i>vnd.google.note" />
 * </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 is a URI from which
 * a Cursor of exactly one (<code>vnd.android.cursor.item) item can
 * be retrieved which contains our note pad data (<code>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.</p>
 * </ol>
 *
 * <p>Given these capabilities, the following intents will resolve to the
 * NotesList activity:</p>
 *
 * <ul>
 *     <li> 

{ action=android.app.action.MAIN } matches all of the * activities that can be used as top-level entry points into an * application.</p> * <li>

{ 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>

{ action=android.intent.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>

{ 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>

{ 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, 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>

 * <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/<i>vnd.google.note" />
 * </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.  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>
 * <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/<i>vnd.google.note" />
 * </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> 

{ action=android.intent.action.VIEW * data=content://com.google.provider.NotePad/notes/<var>{ID} } * shows the user the content of note <var>{ID}.

* <li>

{ action=android.app.action.EDIT * data=content://com.google.provider.NotePad/notes/<var>{ID} } * allows the user to edit the content of note <var>{ID}.

* <li>

{ 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, 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:name="<i>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/<i>vnd.google.note" /> * </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 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) 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") 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>

{ action=com.android.notepad.action.EDIT_TITLE * data=content://com.google.provider.NotePad/notes/<var>{ID} } * displays and allows the user to edit the title associated * with note <var>{ID}.

* </ul> * * <h3>Standard Activity Actions * * <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 * * <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} * <li> {@link #ACTION_POWER_CONNECTED} * <li> {@link #ACTION_POWER_DISCONNECTED} * <li> {@link #ACTION_SHUTDOWN} * </ul> * * <h3>Standard Categories * * <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_INFO} * <li> {@link #CATEGORY_HOME} * <li> {@link #CATEGORY_PREFERENCE} * <li> {@link #CATEGORY_TEST} * <li> {@link #CATEGORY_CAR_DOCK} * <li> {@link #CATEGORY_DESK_DOCK} * <li> {@link #CATEGORY_CAR_MODE} * </ul> * * <h3>Standard Extra Data * * <p>These are the current standard fields that can be used as extra data via * {@link #putExtra}. * * <ul> * <li> {@link #EXTRA_ALARM_COUNT} * <li> {@link #EXTRA_BCC} * <li> {@link #EXTRA_CC} * <li> {@link #EXTRA_CHANGED_COMPONENT_NAME} * <li> {@link #EXTRA_DATA_REMOVED} * <li> {@link #EXTRA_DOCK_STATE} * <li> {@link #EXTRA_DOCK_STATE_CAR} * <li> {@link #EXTRA_DOCK_STATE_DESK} * <li> {@link #EXTRA_DOCK_STATE_UNDOCKED} * <li> {@link #EXTRA_DONT_KILL_APP} * <li> {@link #EXTRA_EMAIL} * <li> {@link #EXTRA_INITIAL_INTENTS} * <li> {@link #EXTRA_INTENT} * <li> {@link #EXTRA_KEY_EVENT} * <li> {@link #EXTRA_PHONE_NUMBER} * <li> {@link #EXTRA_REMOTE_INTENT_TOKEN} * <li> {@link #EXTRA_REPLACING} * <li> {@link #EXTRA_SHORTCUT_ICON} * <li> {@link #EXTRA_SHORTCUT_ICON_RESOURCE} * <li> {@link #EXTRA_SHORTCUT_INTENT} * <li> {@link #EXTRA_STREAM} * <li> {@link #EXTRA_SHORTCUT_NAME} * <li> {@link #EXTRA_SUBJECT} * <li> {@link #EXTRA_TEMPLATE} * <li> {@link #EXTRA_TEXT} * <li> {@link #EXTRA_TITLE} * <li> {@link #EXTRA_UID} * </ul> * * <h3>Flags * * <p>These are the possible flags that can be used in the Intent via * {@link #setFlags} and {@link #addFlags}.
