MediaItemStatus


class MediaItemStatus


Describes the playback status of a media item.

This class is part of the remote playback protocol described by the MediaControlIntent class.

As a media item is played, it transitions through a sequence of states including: pending, buffering, playing, paused, finished, canceled, invalidated, and error. Refer to the documentation of each state for an explanation of its meaning.

While the item is playing, the playback status may also include progress information about the content position and content duration although not all route destinations will report it.

To monitor playback status, the application should supply a PendingIntent to use as the item status update receiver for a given playback request. Note that the status update receiver will only be invoked for major status changes such as a transition from playing to finished.

The status update receiver will not be invoked for minor progress updates such as changes to playback position or duration. If the application wants to monitor playback progress, then it must use the get status request to poll for changes periodically and estimate the playback position while playing. Note that there may be a significant power impact to polling so the application is advised only to poll when the screen is on and never more than about once every 5 seconds or so.

This object is immutable once created using a Builder instance.

String

Constants

EXTRA_HTTP_RESPONSE_HEADERS

Added in 1.1.0
const val EXTRA_HTTP_RESPONSE_HEADERS = "android.media.status.extra.HTTP_RESPONSE_HEADERS": String!

Bundle extra: HTTP response headers.

Specifies the HTTP response headers that were returned when the content was requested from the network. The headers may include additional information about the content or any errors conditions that were encountered while trying to fetch the content.

The value is a android.os.Bundle of string based key-value pairs that describe the HTTP response headers.

EXTRA_HTTP_STATUS_CODE

Added in 1.1.0
const val EXTRA_HTTP_STATUS_CODE = "android.media.status.extra.HTTP_STATUS_CODE": String!

Integer extra: HTTP status code.

Specifies the HTTP status code that was encountered when the content was requested after all redirects were followed. This key only needs to specified when the content uri uses the HTTP or HTTPS scheme and an error occurred. This key may be omitted if the content was able to be played successfully; there is no need to report a 200 (OK) status code.

The value is an integer HTTP status code, such as 401 (Unauthorized), 404 (Not Found), or 500 (Server Error), or 0 if none.

PLAYBACK_STATE_BUFFERING

Added in 1.1.0
const val PLAYBACK_STATE_BUFFERING = 3: Int

Playback state: Buffering or seeking to a new position.

Indicates that the media item has been temporarily interrupted to fetch more content. Playback will continue automatically when enough content has been buffered.

PLAYBACK_STATE_CANCELED

Added in 1.1.0
const val PLAYBACK_STATE_CANCELED = 5: Int

Playback state: Canceled.

Indicates that the media item was explicitly removed from the queue by the application. Items may be canceled and removed from the queue using the remove or stop action or by issuing another play action that has the side-effect of clearing the queue.

A canceled media item cannot be resumed. To play the content again, the application must send a new play or enqueue action.

PLAYBACK_STATE_ERROR

Added in 1.1.0
const val PLAYBACK_STATE_ERROR = 7: Int

Playback state: Playback halted or aborted due to an error.

Examples of errors are no network connectivity when attempting to retrieve content from a server, or expired user credentials when trying to play subscription-based content.

A media item in the error state cannot be resumed. To play the content again, the application must send a new play or enqueue action.

PLAYBACK_STATE_FINISHED

Added in 1.1.0
const val PLAYBACK_STATE_FINISHED = 4: Int

Playback state: Finished.

Indicates that the media item played to the end of the content and finished normally.

A finished media item cannot be resumed. To play the content again, the application must send a new play or enqueue action.

PLAYBACK_STATE_INVALIDATED

Added in 1.1.0
const val PLAYBACK_STATE_INVALIDATED = 6: Int

Playback state: Invalidated.

Indicates that the media item was invalidated permanently and involuntarily. This state is used to indicate that the media item was invalidated and removed from the queue because the session to which it belongs was invalidated (typically by another application taking control of the route).

When invalidation occurs, the application should generally wait for the user to perform an explicit action, such as clicking on a play button in the UI, before creating a new media session to avoid unnecessarily interrupting another application that may have just started using the route.

An invalidated media item cannot be resumed. To play the content again, the application must send a new play or enqueue action.

PLAYBACK_STATE_PAUSED

Added in 1.1.0
const val PLAYBACK_STATE_PAUSED = 2: Int

Playback state: Paused.

Indicates that playback of the media item has been paused. Playback can be resumed using the resume action.

PLAYBACK_STATE_PENDING

Added in 1.1.0
const val PLAYBACK_STATE_PENDING = 0: Int

Playback state: Pending.

Indicates that the media item has not yet started playback but will be played eventually.

PLAYBACK_STATE_PLAYING

Added in 1.1.0
const val PLAYBACK_STATE_PLAYING = 1: Int

Playback state: Playing.

Indicates that the media item is currently playing.
