android - 如何清除堆？

Question

我正在开发相机应用程序。如果我第一次拍摄图像，它工作正常，但如果我再次拍摄照片，它会抛出错误

ERROR/dalvikvm-heap(2398): 10077696-byte external allocation too large for this process." VM won't let us allocate 10077696 bytes" and finally"05-02 05:35:38.390: ERROR/AndroidRuntime(2398): FATAL EXCEPTION: main 05-02 05:35:38.390: ERROR/AndroidRuntime(2398): java.lang.OutOfMemoryError: bitmap size exceeds VM budget

应用程序强制关闭..如何处理这个如何清除堆和虚拟机？ 请帮忙.. 提前致谢..

我找到了答案。
我使用了以下代码:

BitmapFactory.Options bfOptions=new BitmapFactory.Options();

                bfOptions.inDither=false;                     //Disable Dithering mode

                bfOptions.inPurgeable=true;                   //Tell to gc that whether it needs free memory, the Bitmap can be cleared

                bfOptions.inInputShareable=true;              //Which kind of reference will be used to recover the Bitmap data after being clear, when it will be used in the future

                bfOptions.inTempStorage=new byte[32 * 1024]; 
   CameraTricks.SdCardImage= BitmapFactory.decodeFile(CameraTricks.yu,bfOptions);
CameraTricks.yu is my path to bitmap
