我有一个回收bitmap的问题.我有所有null和代码回收.不确定我做错了什么.

我的代码:

ByteArrayOutputStream stream = new ByteArrayOutputStream();               
bmp = DecodeImage.decodeFile(imgpath, 450, 450, true);
bmp.compress(Bitmap.CompressFormat.JPEG, 100 , stream);     
Image img = Image.getInstance(stream.toByteArray()); 

错误信息:

解码为位图降低分辨率的类.

    public class DecodeImage
       {

       //decodes image and scales it to reduce memory consumption
         public static Bitmap decodeFile(File bitmapFile, int requiredWidth, int 
    requiredHeight, …
