Track quality of experience on Android

The following instructions provide guidance for implementation across all 2.x SDKs. If you are implementing a 1.x version of the SDK, you can download the 1.x Developers Guides here: Download SDKs.

Implemement QoS

  1. Identify when the bitrate changes during media playback and create the
    MediaObject
    instance using the QoS information.
    QoSObject variables:
    These variables are only required if you are planning to track QoS.
    Variable
    Description
    Required
    bitrate
    Current bitrate
    Yes
    startupTime
    Startup time
    Yes
    fps
    FPS value
    Yes
    droppedFrames
    Number of dropped frames
    Yes
    QoS object creation:
    MediaObject qosObject = MediaHeartbeat.createQoSObject(<BITRATE>, <STARTUP_TIME>, <FPS>, <DROPPED_FRAMES>);
  2. Make sure that
    getQoSObject()
    method returns the most updated QoS information.
  3. When playback switches bitrates, call the
    BitrateChange
    event in the Media Heartbeat instance:
    public void onBitrateChange(Observable observable, Object data) { _heartbeat.trackEvent(MediaHeartbeat.Event.BitrateChange, null, null); }
    Update the QoS object and call the bitrate change event on every bitrate change. This provides the most accurate QoS data.
