BitmapFactory.Options opts = new BitmapFactory.Options();
opts.inJustDecodeBounds = true;
BitmapFactory.decodeFile(imageFile, opts);

opts.inSampleSize = computeSampleSize(opts, -1, 128*128);
opts.inJustDecodeBounds = false;
try {
	Bitmap bmp = BitmapFactory.decodeFile(imageFile, opts);
	imageView.setImageBitmap(bmp);
    } catch (OutOfMemoryError err) {
}
 

修改如下，没有出现OOM错误

opts.inSampleSize = computeSampleSize(opts, -1, 1024*1024);

这个讨论的很深入：

	public static Bitmap readBitMap(Context context, int resId){  
        BitmapFactory.Options opt = new BitmapFactory.Options();  
        opt.inPreferredConfig = Bitmap.Config.RGB_565;   
       opt.inPurgeable = true;  
       opt.inInputShareable = true;  
       InputStream is = context.getResources().openRawResource(resId);  
           return BitmapFactory.decodeStream(is,null,opt);  
    }

解决大问题
