Whenever there is an error, the SDK will fire the PLAYER_EVENT_TYPE_ERROR (more on events handling).


It's up to the app how to handle this errors. To ease that handling, the VideoPlayerView class provides these options:

  1. to get an Exception, if one occurred
  2. to get the HTTP error code, if one occurred
  3. to get an AMP defined constant of the error that occurred


The following assumes you have correctly registered an IPlayerEventsListener, that would get the PLAYER_EVENT_TYPE_ERROR

To get a human readable name of the error (for logs and others), you can use the eventID) method.



1. Getting an exception

  • This is accomplished via videoPlayerView.getLastException().
  • Most of the times, the returning value will be a subclass of com.akamai.exoplayer2.ExoPlaybackException.


2. Getting an HTTP error code

  • This is accomplished via videoPlayerView.getLastHttpErrorCode().
  • In case the error was not HTTP related, this method returns a default int value of -1.


3. Getting the AMP defined constant of the error

  • You can find the list of constants at the bottom of the guide. The validation is accomplished via videoPlayerView.getLastErrorCode().
  • To get a human readable description of it (for logs and others), you can use the lastErrorCode) method.




Here is a code snippet that shows the use of all the methods described above:


public boolean onPlayerEvent(int eventID) {
   Log.e("EventsTest", PlayerEvents.getName(eventID));
   boolean isError = IPlayerEventsListener.PLAYER_EVENT_TYPE_ERROR == eventID;
   if (isError)
      int lastErrorCode = videoPlayerView.getLastErrorCode();
      int lastHttpErrorCode = videoPlayerView.getLastHttpErrorCode();
      Exception lastException = videoPlayerView.getLastException();

      //Note lastException could be null


      String errorName = ErrorEvents.getDescription(lastErrorCode);
      String errorMessage = "PLAYER_EVENT_TYPE_ERROR: " + errorName + " (" + lastHttpErrorCode + ") " + lastException;
      Log.e("EventsTest", errorMessage);
   return false;


The AMP defined constant errors are the following: 


No error

public static final int ERROR_SUCCESS = 0;


Network access is not available

public static final int ERROR_NETWORK_UNAVAILABLE = 1;


Resource (stream URL) doesn't exist

public static final int ERROR_NETWORK_RESOURCE_DONT_EXIST = 2;


Access not allowed to the provided stream URL

public static final int ERROR_NETWORK_SECURITY_ISSUE = 3;


The provided stream doesn't have a known format

public static final int ERROR_FORMAT_UNKNOWN = 4;


There was an issue while allocating resources for playback

public static final int ERROR_RESOURCES_ISSUE = 5;


The provided stream contains format errors

public static final int ERROR_TS_SEGMENT_INVALID = 6;


When there is an error triggered from Exoplayer directly, it would be reported with the following Error code + the Exoplayer error code:  


Last Error code, Exoplayer is reporting an error directly

public static final int EXO2_ERROR_BASE = 7;


Exoplayer error codes:


 * The error occurred loading data from a {@link MediaSource}.

 * <p>

 * Call {@link #getSourceException()} to retrieve the underlying cause.


public static final int TYPE_SOURCE = 0;


 * The error occurred in a {@link Renderer}.

 * <p>

 * Call {@link #getRendererException()} to retrieve the underlying cause.


public static final int TYPE_RENDERER = 1;


 * The error was an unexpected {@link RuntimeException}.

 * <p>

 * Call {@link #getUnexpectedException()} to retrieve the underlying cause.


public static final int TYPE_UNEXPECTED = 2;
