谁能帮我？
回答by Torid
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 nutsfor background. To get round this, you will have to look carefully at your bitmap usage
“位图大小超出VM预算”错误实际上是在原生图形库（Skia）中。这有点令人困惑，因为问题实际上是 Skia 在位图数据的本机堆中耗尽了内存。有关背景，请参阅BitmapFactory OOM 使我发疯。为了解决这个问题，您必须仔细查看您的位图使用情况
- making sure that you do not leave bitmap references floating
- doing a recycle / null onn bitmaps as they become free (this appears to help).
- 确保您不会让位图引用浮动
- 在位图免费时对其进行回收 / null onn（这似乎有帮助）。

Use sampling to read bitmap. May be error occurred due to memory leaks.
使用采样读取位图。可能是由于内存泄漏导致的错误。
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 4;
Bitmap bitmap=BitmapFactory.decodeFile(path,options);
