BitmapAsyncTask--getSampleBitmap--return BitmapFactory.decodeStream(stream, null, options);为null

/**
*
* @param is 第二次压缩容易为空
* @param width
* @param height
* @return
*/
private Bitmap getSampleBitmap(InputStream is, int width, int height)
{

	BufferedInputStream stream = new BufferedInputStream(is);
	stream.mark(4 * 1024);
	final BitmapFactory.Options options = new BitmapFactory.Options();
	options.inJustDecodeBounds = true;
	BitmapFactory.decodeStream(stream, null, options);
	calculateInSampleSize(width, height, options, true);
	try
	{
		stream.reset();
	} catch (IOException e)
	{
	}
	return BitmapFactory.decodeStream(stream, null, options);
}

建议修改一下：
private Bitmap getSampleBitmap2(byte[] data, int width, int height)
{
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeByteArray(data, 0, data.length, options);
calculateInSampleSize(width, height, options, true);
return BitmapFactory.decodeByteArray(data, 0, data.length, options);
}

嗯嗯，执行过程中，没遇到过。你遇到过null异常么？

你可以多验证下，如果工程中的确实有问题，你这个比较稳定，可以提个分支，我给你合进来~
