Вы не инициализирован ImageButton в вашем onCreate() и закрыть приложение просто написать android.os.Process.killProcess(android.os.Process.myPid()), который будет убивать ваше приложение полностью.

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_numbers); 
    exit=(ImageButton)findViewById(R.id.yourid); 
     ............... 
    ............... 
    exit.setOnClickListener(new View.OnClickListener() {   
     @Override 
     public void onClick(View paramView) 
     { 
      android.os.Process.killProcess(android.os.Process.myPid()) ;  

     } 
    });

moveTaskToBack(boolean nonRoot) Переместить задачу, содержащую эту деятельность к задней части стека деятельности. Он не закрывает приложение, но приложение будет в фоновом режиме.

Возможно, вы получили приложение из-за метода onResume(), где вы непосредственно начинаете MediaPlayer без инициализации. Поскольку onResume() вызывается до onCreate(). Так просто инициализировать MediaPlayer BG в вашем onResume(), как показано ниже:

@Override 
protected void onResume() { 
super.onResume(); 
BG=new MediaPlayer(); 
}

Вы забыли инициализировать exitImageButton. инициализировать его ...

exit = (ImageButton)findViewById(R.id.id_of_image_button) 
exit.setOnClickListener(new View.OnClickListener() {   
    @Override 
     public void onClick(View paramView) {
