我有 199KB 的图像存储在内部存储器中。我的设备的总内存为 512 MB。安卓版本为 2.3.5 。所以我正在做的是我在运行时将所有图像制作为可绘制的位图。
我收到以下异常:
10-10 14:16:03.782: E/dalvikvm-heap(20331): 73632-byte external allocation too large for this process.
10-10 14:16:03.782: E/dalvikvm(20331): Out of memory: Heap Size=6599KB, Allocated=3949KB, Bitmap Size=13871KB, Limit=20480KB

这是我的代码:
File myDir =act.getApplicationContext().getDir(CURRENT_THEME, act.MODE_PRIVATE);
public BitmapDrawable getResourceFromInternalStorage(String resourceName)
{
// Runtime.getRuntime().gc();
String filename = resourceName;
File file = new File(myDir, filename+".png");
Resources res = act.getResources();
BitmapDrawable bd =null;
bitmap=null;
try
{
// BitmapFactory.Options options = new BitmapFactory.Options();
// options.inJustDecodeBounds = true;
// options.inSampleSize = 32;
BitmapFactory.Options bmpFactoryOptions = new BitmapFactory.Options();
bmpFactoryOptions.inJustDecodeBounds=true;
BitmapFactory.decodeFile(file.getPath(),bmpFactoryOptions);
long reqsize=bmpFactoryOptions.outWidth*bmpFactoryOptions.outHeight*2;
long allocNativeHeap = Debug.getNativeHeapAllocatedSize();
final long heapPad=(long) Math.max(4*1024*1024,Runtime.getRuntime().maxMemory()*0.1);
if ((reqsize + allocNativeHeap + heapPad) >= Runtime.getRuntime().maxMemory())
{
Toast.makeText(act, "exception", Toast.LENGTH_LONG).show();
// bitmap.recycle();
// Runtime.getRuntime().gc();
// System.gc();
// return null;
}
bmpFactoryOptions.inJustDecodeBounds=false;
bitmap=BitmapFactory.decodeFile(file.getPath(),bmpFactoryOptions);
bd = new BitmapDrawable(res, bitmap);
}
catch(java.lang.OutOfMemoryError e)
{
Log.v("Exceptional exception", e.getMessage());
bitmap.recycle();
System.gc();
}
finally{
}
return bd;
}
