내 안드로이드 응용 프로그램이 예기치 않게 중지

Question

내 응용 프로그램은 각각 다음과 같이 새로운 의도를 만드는 세 개의 버튼이 있습니다 : 나는 버튼을 클릭하면

Button button3 = (Button) findViewById(R.id.Button03); 
    button3.setOnClickListener(new View.OnClickListener() { 
     public void onClick(View view) { 
      Intent myIntent = new Intent(view.getContext(), Shout.class); 
      startActivityForResult(myIntent, 0); 
     } 

    }); 

그래서 기본적으로 프로젝트 내 다른 클래스를 시작합니다. 첫 번째 화면으로 돌아가고 싶을 때 뒤로 키를 누릅니다. 잘 작동하지만 버튼과 뒤로 키를 약 5 번 누르면 앱이 다운됩니다. 왜? 내가 클래스에서 돌아가 후에도 sensorlistener 여기처럼 최고 속도로 계속 실행 것으로 나타났습니다 :

은 메모리 부족 문제처럼 보이지만 내가 어떻게 내려 닫을 수 있습니다 뒤로 버튼을 클릭해도이 문제가 발생하지 않거나 문제에 대한 또 다른 대답이 있습니까? 뒤로 키를 클릭 한 후 Sensor Listener가 중지되지 않는 이유는 무엇입니까? 실례합니다. o)

Answer 1

당신의보기 중 하나에 비트 맵이 있습니다.이 비트 맵은이보기의 xml을 부풀려서 문제의 비트 맵을 디코딩하려고 할 때 충분히 큽니다. 메모리 오류.

이 드로어 블을 최적화 할 수 있는지 확인하거나 활동의 온 디스트로이어에서 클렌징을 시도하십시오.

Answer 2

센서 리스너를 등록 해제해야합니다 (가급적이면 활동의 onPause() 메소드에서). 그렇지 않으면 시스템에서 참조를 유지하며 가비지 수집을 위해 해제되지 않습니다. 등록 된 리스너가 활동 자체이거나 비트 맵에 대한 직접 또는 간접 참조가있는 다른 것이면 비트 맵은 가비지 콜렉터에 공개되지 않습니다.
