Android解码器->解码位图下载返回false [英] Android decoder->decode returned false for Bitmap download

问题描述

我已经开始得到一个

DEBUG/skia(xxxx): --- decoder->decode returned false 

关于我在 ImageViews 中使用的一些来自 Facebook 的个人资料图片的问题.大多数都可以完美运行，但偶尔我会发现一个永远无法运行的东西.

issue on a few profile images from Facebook that I use in ImageViews. Most work perfectly, but every once in a while I discover one that never works.

出于向后兼容性的原因，我正在针对 Android 1.6 编译我的应用程序.

I am compiling my application against Android 1.6 for backward compatibility reasons.

我进行了一些挖掘并发现了许多有关该问题的线索.我已经在使用这里讨论的 FlushedInputStream:http://code.google.com/p/android/issues/detail?id=6066

I did some digging and discovered a number of threads on the issue. I'm already using the FlushedInputStream discussed here: http://code.google.com/p/android/issues/detail?id=6066

Bitmap b = BitmapFactory.decodeStream(new FlushedInputStream(is));
imageView.setImageBitmap(b);

这是一个给我带来麻烦的例子:http://profile.ak.fbcdn.net/hprofile-ak-snc4/hs269.snc3/23132_639284607_390_q.jpg

Here's an example that's causing me trouble: http://profile.ak.fbcdn.net/hprofile-ak-snc4/hs269.snc3/23132_639284607_390_q.jpg

有人可以查看图像并帮助我找出导致问题的原因吗?

Can someone check out the image and help me figure out what's causing the trouble?

推荐答案

FlushedInputStream(is) 中存在一个错误.它在慢速连接时失败，但您可以尝试我的神奇代码来修复它.

There is a bug in FlushedInputStream(is). it fails on slow connections but you can try my magical code to fix it.

Bitmap b = BitmapFactory.decodeStream(new FlushedInputStream(is));
imageView.setImageBitmap(b);

在你的方法之外创建一个静态类

create a static class outside your method

 static class FlushedInputStream extends FilterInputStream {
        public FlushedInputStream(InputStream inputStream) {
            super(inputStream);
        }

        @Override
        public long skip(long n) throws IOException {
            long totalBytesSkipped = 0L;
            while (totalBytesSkipped < n) {
                long bytesSkipped = in.skip(n - totalBytesSkipped);
                if (bytesSkipped == 0L) {
                    int b = read();
                    if (b < 0) {
                        break;  // we reached EOF
                    } else {
                        bytesSkipped = 1; // we read one byte
                    }
                }
                totalBytesSkipped += bytesSkipped;
            }
            return totalBytesSkipped;
        }
    }

你开始吧..现在你不会有任何问题了.

and here you go.. now you will not have any problem.
