can anyone help me?
回答1:
The "bitmap size exceeds VM budget" error is actually in the native graphics library (Skia). It is a tad confusing as the problem is really that Skia has run out of memory in the native heap for bitmap data. See BitmapFactory OOM driving me nuts for background. To get round this, you will have to look carefully at your bitmap usage
- making sure that you do not leave bitmap references floating
- doing a recycle / null onn bitmaps as they become free (this appears to help).
回答2:
Use sampling to read bitmap. May be error occurred due to memory leaks.
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 4;
Bitmap bitmap=BitmapFactory.decodeFile(path,options);
