Encoding Instance

public class Activity implements NativeListener {
    public void onStart() {
        int ret = AudioTrackPlayer.startAudio();
        if (ret == AudioTrackPlayer.VMI_SUCCESS) {
            // The audio is successfully enabled.
        }
        if (ret == AudioTrackPlayer.VMI_AUDIO_ENGINE_CLIENT_START_FAIL) {
            // The audio fails to be enabled.
        }
    }
    public void onStop() {
        int ret = AudioTrackPlayer.stopAudio();
        if (ret == AudioTrackPlayer.VMI_SUCCESS) {
            // The audio is successfully muted.
        }
        if (ret == AudioTrackPlayer.VMI_AUDIO_ENGINE_CLIENT_STOP_FAIL) {
            // The audio fails to be muted.
        }
