Попытка вызвать виртуальный метод 'boolean android.media.AudioManager.isBluetoothA2dpOn ()' для ссылки на пустой объект

Я получаю странный тип Crash в приложении, захваченном во время Crash Analytics, даже если я не использовал код для устройств Bluetooth и не использовал эти строки isBluetoothA2dpOn () . Кроме того, я не смог отследить код, с которого он был запущен журналами трассировки, захваченными Crash Analytics . Если кто-то сталкивался с той же проблемой, то предложите лучший ответ для этого.

на android.view.View.dispatchTouchEvent (View.java:10779) 

Fatal Exception: java.lang.NullPointerException: Attempt to invoke virtual method 'boolean android.media.AudioManager.isBluetoothA2dpOn()' on a null object reference

Отредактированная отправка TouchEvent 

    @Override
public boolean dispatchTouchEvent(MotionEvent ev) {
    if (ev.getAction() == MotionEvent.ACTION_DOWN) {
        Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
            @Override
            public void run() {
                if (touchListener != null) {
                    if (!haltRegistration) {
                        touchListener.onTouchEvent();
                    } else {
                        haltRegistration = false;
                    }
                } else {
                    Log.d(TAG, "listener was null...");
                }
            }
        }, 300);

    }
    return super.dispatchTouchEvent(ev);
}
