Android: Strange out of memory issue while loading an image to a Bitmap object

내가 게임을 만드는거야. 그것은 완벽하게 작동하지만 때로는 다음과 같은 메시지를 던져 : Out of memory on a 1024016-byte allocation! 나는 왜 안드로이드가 실제로 1MB의 메모리를 할당 할 수 없는지 이해하지 못한다. 나는 BitmapFactory.decodeResource(res, id) 함수를 사용하고 있습니다. 비트 맵이 쓸모 없게되면 즉시 재활용합니다! 심지어 비트 맵의 ​​크기를 줄였습니다! 누군가가이 문제를 해결하는 방법을 알고 있으면 감사하겠습니다! 아래 로그 캣 :

Answer 1

public static Bitmap getBmpFromRes(Resources res, int id){ 
    BitmapFactory.Options options = new BitmapFactory.Options(); 
    options.inSampleSize = 1; // sample size value depends upon your image so you have to    calculate it on run time. 
    options.inPurgeable = true; //IMP 
    return BitmapFactory.decodeResource(res, id,options); }
