SkImageDecoder::Factory returned null

Android 开发中，使用HttpURLConnection加载网络图片的时候，
偶尔会出现：“SkImageDecoder::Factory returned null”错误！
代码如下：
 
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.connect();
InputStream input = connection.getInputStream();
bitmap[i] = BitmapFactory.decodeStream(input);
System.out.println("the bitmap is " + bitmap[i]);
 
输出：

SkImageDecoder::Factory returned null the bitmap is null
 
 
 
如果使用apache的HttpClient的话，就不会有问题了，
代码如下：
 
HttpGet httpRequest = new HttpGet(url);
HttpClient httpclient = new DefaultHttpClient();
HttpResponse response = (HttpResponse) httpclient.execute(httpRequest);
HttpEntity entity = response.getEntity();
BufferedHttpEntity bufferedHttpEntity = new BufferedHttpEntity(entity);
InputStream is = bufferedHttpEntity.getContent();
bitmap = BitmapFactory.decodeStream(is);
 
 
这里再一次证明了
 
apache的HttpClient比Java的HttpURLConnection强大
