프로그래밍 방식으로 비행기 모드를 조작하는 방법은 무엇입니까? android

Question

배터리 절약 앱 만들기를 위해 비행기 모드를 켜거나 끕니다. 정말 이렇게 할 방법이 없습니까? 난 내 안드로이드 넥서스 7에서 응용 프로그램을 실행할 때 내가 잘못 뭐하는 거지, 아무 일도 일어나지 않습니다 ...

내 현재 코드인가?

Settings.System.putBoolean 대신 Settings.System.putInt을 사용해야합니다.

if (getAPstate() == true){ 
      testButton.setText("Turn Airplane Mode OFF"); 
      Settings.System.putInt(getContentResolver(), Settings.System.AIRPLANE_MODE_ON, 0); 
      st = false; 


     }else { 
      testButton.setText("Turn Airplane Mode ON"); 
      Settings.System.putInt(getContentResolver(),Settings.System.AIRPLANE_MODE_ON, 1); 
      st = true; 
     }
