/**
* 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}.
*
* 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.
*
* <div class="special reference">
* <h3>Developer Guides</h3>
* For information about how to create and resolve intents, read the
* <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a>
* developer guide.
* </div>
*
* <a name="IntentStructure"></a>
* <h3>Intent Structure</h3>
* The primary pieces of information in an intent are:
*
* <ul>
* <li> action -- The general action to be performed, such as
* {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN},
* etc.
* </li>
* <li> data -- The data to operate on, such as a person record
* in the contacts database, expressed as a {@link android.net.Uri}.
* </li>
* </ul>
*
*
* 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".
* </li>
* <li> {@link #ACTION_DIAL} content://contacts/people/1 -- Display
* the phone dialer with the person filled in.
* </li>
* <li> {@link #ACTION_VIEW} tel:123 -- Display
* the phone dialer with the given number filled in. Note how the
* VIEW action does what is considered the most reasonable thing for
* a particular URI.
* </li>
* <li> {@link #ACTION_DIAL} tel:123 -- Display
* the phone dialer with the given number filled in.
* </li>
* <li> {@link #ACTION_EDIT} content://contacts/people/1 -- Edit
* information about the person whose identifier is "1".
* </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 { {@link #ACTION_VIEW} content://contacts/people/N }
* being used to start an activity to display that person.
* </li>
* </ul>
*
* In addition to these primary attributes, there are a number of secondary
* attributes that you can also include with an intent:
*
* <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.
* <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.
* <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.
* <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.
* </ul>
*
* Here are some examples of other operations you can specify as intents
* using these additional parameters:
*
* <ul>
* <li> {@link #ACTION_MAIN} with category {@link #CATEGORY_HOME} --
* Launch the home screen.
* </li>
* <li> {@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.
* </li>
* <li> {@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.
* </li>
* </ul>
*
* 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.
*
* <a name="IntentResolution"></a>
* <h3>Intent Resolution</h3>
*
* 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>
*
* 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 <code>AndroidManifest.xml</code> file as
* follows:
*
* <ul>
* <li> The action, if given, must be listed by the component as
* one it handles.
* <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.
* <li> For data that is not a <code>content:</code> URI and where no explicit
* type is included in the Intent, instead the scheme 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> 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()}.
* </ul>
*
* 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.
*
* <pre> <manifest xmlns:android="http://schemas.android.com/apk/res/android"

*
* </application>
* </manifest></pre>
*
* 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:name="{@link #ACTION_MAIN android.intent.action.MAIN}" />
* <category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" />
* </intent-filter></pre>
* 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.
* <li><pre>
* <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 android:mimeType="vnd.android.cursor.dir/vnd.google.note" />
* </intent-filter></pre>
* 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 required for the
* {@link Context#startActivity Context.startActivity} method to resolve your
* activity when its component name is not explicitly specified.
* <li><pre>
* <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></pre>
* This filter describes the ability to 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.
* </ol>
*
* Given these capabilities, the following intents will resolve to the
* NotesList activity:
*
* <ul>
* <li> { action=android.app.action.MAIN } matches all of the
* activities that can be used as top-level entry points into an
* application.
* <li> { action=android.app.action.MAIN,
* category=android.app.category.LAUNCHER } is the actual intent
* used by the Launcher to populate its top-level list.
* <li> { 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.
* <li> { 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.
* <li> { 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.
* </ul>
*
* 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: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></pre>
* 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.
* <li><pre>
* <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></pre>
* 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.
* </ol>
*
* Given these capabilities, the following intents will resolve to the
* NoteEditor activity:
*
* <ul>
* <li> { action=android.intent.action.VIEW
* data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }
* shows the user the content of note <var>{ID}</var>.
* <li> { action=android.app.action.EDIT
* data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }
* allows the user to edit the content of note <var>{ID}</var>.
* <li> { 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.
* </ul>
*
* 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:
*
* <pre>
* <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></pre>
*
* 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.
*
* 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.
*
* Given these capabilities, the following intent will resolve to the
* TitleEditor activity:
*
* <ul>
* <li> { action=com.android.notepad.action.EDIT_TITLE
* data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }
* displays and allows the user to edit the title associated
* with note <var>{ID}</var>.
* </ul>
*

* </ul>
* 
* This action should be used when the user will naturally expect to

/**
* Activity Action: Allow the user to select a particular kind of data and
* return it. This is different than {@link #ACTION_PICK} in that here we
* just say what kind of data is desired, not a URI of existing data from
* which the user can pick. An ACTION_GET_CONTENT could allow the user to
* create the data as it runs (for example taking a picture or recording a
* sound), let them browse over the web and download the desired data,
* etc.
* 
* There are two main ways to use this action: if you want a 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.
* 
* In this case, you should wrap the GET_CONTENT intent with a chooser
* (through {@link #createChooser}), which will give the proper interface
* for the user to pick how to send your data and allow you to specify
* a prompt indicating what they are doing. You will usually specify a
* broad MIME type (such as image/* or {@literal *}/*), resulting in a
* broad range of content types the user can select from.
* 
* When using such a broad GET_CONTENT action, it is often desirable to
* only pick from data that can be represented as a stream. This is
* accomplished by requiring the {@link #CATEGORY_OPENABLE} in the Intent.
* 
* Callers can optionally specify {@link #EXTRA_LOCAL_ONLY} to request that
* the launched content chooser only returns results representing data that
* is locally available on the device. For example, if this extra is set
* to true then an image picker should not show any pictures that are available
* from a remote server but not already on the local device (thus requiring
* they be downloaded when opened).
* 
* 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. You may use {@link #EXTRA_ALLOW_MULTIPLE} to
* allow the user to select multiple items.
* 
* Output: The URI of the item that was picked. This must be a content:
* URI so that any receiver can access it.
