잡히지 않은 예외로 스레드가 종료 됨 android (OutOfMemory)

Question

때때로 작동하지만 때로는 작동하지 않습니다.
누구든지 내가 문제를 찾아 내고 그에 대처하는 방법을 알려줄 수 있습니까? 고맙습니다!

Answer 1

첫째, OOM 예외는 없습니다 처리 방지해야합니다.

보통 OOM 예외는 당신은 그들이 너무 큰 경우 메모리에로드하기 전에 당신의 bitmaps을 확장 할 수 OOM을 방지하기 때문에 crash.In 순서에 응용 프로그램을 일으키는 RAM이 많이 걸립니다 bitmaps에 발생합니다. BitmapFactory.Options을 사용하고 요구 사항에 따라 축소 할 수 있습니다.

public static Bitmap decodeSampledBitmapFromPath(String path, int reqWidth, 
       int reqHeight) { 

     final BitmapFactory.Options options = new BitmapFactory.Options(); 
     options.inJustDecodeBounds = true; 
     BitmapFactory.decodeFile(path, options); 

     options.inSampleSize = calculateInSampleSize(options, reqWidth, 
       reqHeight); 

     // Decode bitmap with inSampleSize set 
     options.inJustDecodeBounds = false; 
     Bitmap bmp = BitmapFactory.decodeFile(path, options); 
     return bmp; 
    } 

    public static int calculateInSampleSize(BitmapFactory.Options options, 
      int reqWidth, int reqHeight) { 

     final int height = options.outHeight; 
     final int width = options.outWidth; 
     int inSampleSize = 1; 

     if (height > reqHeight || width > reqWidth) { 
      if (width > height) { 
        inSampleSize = Math.round((float) height/(float) reqHeight); 
      } else { 
        inSampleSize = Math.round((float) width/(float) reqWidth); 
      } 
     } 
    return inSampleSize; 
    }
