Не удается воспроизвести музыку с помощью MusicService во фрагменте

У меня есть фрагмент, который дает мне список всех песен, которые я сохранил на своем телефоне. Когда я нажимаю на определенную песню в своем списке, я должен иметь возможность воспроизвести ее с помощью MusicService.

Этот фрагмент (menu2_Fragment) инициализируется в ActionBarActivity при выборе определенного элемента ящика. См. следующий код:

@Override
public void onNavigationDrawerItemSelected(int position) {
    Fragment objFragment = null;

    switch(position){
        case 0:
            objFragment = new menu1_Fragment();
            getSupportActionBar().setTitle("Scan for Users");
            break;
        case 1:
            objFragment = new menu2_Fragment();
            getSupportActionBar().setTitle("Your Music");
            // objFragment = new MyMusicFragment();
            break;
        case 2:
            objFragment = new menu3_Fragment();
            getSupportActionBar().setTitle("Popular Music");
    }

    // update the main content by replacing fragments
    FragmentManager fragmentManager = getSupportFragmentManager();
    fragmentManager.beginTransaction()
            .replace(R.id.container, objFragment)
            .commit();
}

Это код фрагмента:

Когда я нажимаю элемент в ListView, вместо воспроизведения песни мое приложение падает, и я получаю следующее сообщение об ошибке:

Функция воспроизведения музыки отлично работает, если она реализована не внутри фрагмента, а внутри действия. Кто-нибудь видел такую ​​​​ошибку раньше?
