Xamarin Binding error: java.lang.NoSuchMethodError: No virtual method build()Lcom/google/android/exoplayer2/DefaultLoadControl

Question

I have created a Binding Library for Triton Digital Mobile SDK and integrated it on my Xamarin.Android project.

I have added this code to my project to test the binding library

using Com.Tritondigital.Player;
namespace MyProject.Droid.Services
{
    public class AudioSource : Service, AudioManager.IOnAudioFocusChangeListener
    {
        .
        .
        .
        public void Play()
        {
            Bundle settings = new Bundle();
            settings.PutString(TritonPlayer.SettingsStreamUrl, "http://storage.googleapis.com/automotive-media/Jazz_In_Paris.mp3");

            // Create the player.
            TritonPlayer player = new TritonPlayer(this, settings);
            player.Play();
        }
        .
        .
        .
    }
}

But during runtime, it throws a FATAL EXCEPTION

Any idea on how to resolve this?

Answer 1

Try to add the jar for exoplayer in your binding project with embeddedjar build action mentioned in the documentation
