MediaBrowserServiceCompat


public abstract class MediaBrowserServiceCompat extends Service


Base class for media browse services.

Media browse services enable applications to browse media content provided by an application and ask the application to start playing it. They may also be used to control content that is already playing by way of a MediaSessionCompat.

To extend this class, you must declare the service in your manifest file with an intent filter with the SERVICE_INTERFACE action. For example:
<service android:name=".MyMediaBrowserServiceCompat"
         android:label="@string/service_name" >
    <intent-filter>
        <action android:name="android.media.browse.MediaBrowserService" />
    </intent-filter>
</service>

Summary

Gets the session token, or null if it has not yet been created or if it has been destroyed.

notifyChildrenChanged

Added in 1.1.0

Notifies all connected media browsers that the children of the specified parent id have changed in some way. This will cause browsers to fetch subscribed content again.

Parameters
@NonNull String parentId

The id of the parent media item whose children changed.

notifyChildrenChanged

Added in 1.1.0
public void notifyChildrenChanged(@NonNull String parentId, @NonNull Bundle options)

Notifies all connected media browsers that the children of the specified parent id have changed in some way. This will cause browsers to fetch subscribed content again.

Parameters
@NonNull String parentId

The id of the parent media item whose children changed.

@NonNull Bundle options

A bundle of service-specific arguments to send to the media browse. The contents of this bundle may contain the information about the change.

onBind

Added in 1.1.0
public IBinder onBind(Intent intent)

onCustomAction

Added in 1.1.0
public void onCustomAction(
    @NonNull String action,
    Bundle extras,
    @NonNull MediaBrowserServiceCompat.Result<Bundle> result
)

Called to request a custom action to this service.

Implementations must call either sendResult or sendError. If the requested custom action will be an expensive operation detach may be called before returning from this function, and then the service can send the result later when the custom action is completed. Implementation can also call sendProgressUpdate to send an interim update to the requester.

If the requested custom action is not supported by this service, call sendError. The default implementation will invoke sendError.

Parameters
@NonNull String action

The custom action sent from the media browser.

Bundle extras

The bundle of service-specific arguments sent from the media browser.

@NonNull MediaBrowserServiceCompat.Result<Bundle> result

The Result to send the result of the requested custom action.

onDestroy

@CallSuper
@MainThread
public void onDestroy()

onGetRoot

Added in 1.1.0
public abstract @Nullable MediaBrowserServiceCompat.BrowserRoot onGetRoot(
    @NonNull String clientPackageName,
    int clientUid,
    @Nullable Bundle rootHints
)

Called to get the root information for browsing by a particular client.

The implementation should verify that the client package has permission to access browse media information before returning the root id; it should return null if the client is not allowed to access this information.

Parameters
@NonNull String clientPackageName

The package name of the application which is requesting access to browse media.

int clientUid

The uid of the application which is requesting access to browse media.

@Nullable Bundle rootHints

An optional bundle of service-specific arguments to send to the media browse service when connecting and retrieving the root id for browsing, or null if none. The contents of this bundle may affect the information returned when browsing.

Returns
@Nullable MediaBrowserServiceCompat.BrowserRoot

The BrowserRoot for accessing this app's content or null.

onLoadChildren

Added in 1.1.0
public abstract void onLoadChildren(
    @NonNull String parentId,
    @NonNull MediaBrowserServiceCompat.Result<List<MediaBrowserCompat.MediaItem>> result
)

Called to get information about the children of a media item.

Implementations must call result.sendResult with the list of children. If loading the children will be an expensive operation that should be performed on another thread, result.detach may be called before returning from this function, and then result.sendResult called when the loading is complete.

In case the media item does not have any children, call sendResult with an empty list. When the given parentId is invalid, implementations must call result.sendResult with null, which will invoke onError.

Parameters
@NonNull String parentId

The id of the parent media item whose children are to be queried.

@NonNull MediaBrowserServiceCompat.Result<List<MediaBrowserCompat.MediaItem>> result

The Result to send the list of children to.

onLoadChildren

Added in 1.1.0
public void onLoadChildren(
    @NonNull String parentId,
    @NonNull MediaBrowserServiceCompat.Result<List<MediaBrowserCompat.MediaItem>> result,
    @NonNull Bundle options
)

Called to get information about the children of a media item.

Implementations must call result.sendResult with the list of children. If loading the children will be an expensive operation that should be performed on another thread, result.detach may be called before returning from this function, and then result.sendResult called when the loading is complete.

In case the media item does not have any children, call sendResult with an empty list. When the given parentId is invalid, implementations must call result.sendResult with null, which will invoke onError.

Parameters
@NonNull String parentId

The id of the parent media item whose children are to be queried.

@NonNull MediaBrowserServiceCompat.Result<List<MediaBrowserCompat.MediaItem>> result

The Result to send the list of children to.

@NonNull Bundle options

A bundle of service-specific arguments sent from the media browse. The information returned through the result should be affected by the contents of this bundle.

onLoadItem

Added in 1.1.0
public void onLoadItem(
    String itemId,
    @NonNull MediaBrowserServiceCompat.Result<MediaBrowserCompat.MediaItem> result
)

Called to get information about a specific media item.

Implementations must call result.sendResult. If loading the item will be an expensive operation result.detach may be called before returning from this function, and then result.sendResult called when the item has been loaded.

When the given itemId is invalid, implementations must call result.sendResult with null.

The default implementation will invoke onError.

Parameters
String itemId

The id for the specific MediaBrowserCompat.MediaItem.

@NonNull MediaBrowserServiceCompat.Result<MediaBrowserCompat.MediaItem> result

The Result to send the item to, or null if the id is invalid.

onSearch

The default implementation will invoke onError.

Parameters
@NonNull String query

The search query sent from the media browser. It contains keywords separated by space.

Bundle extras
