Android 获取网络图片方法

private Bitmap getUrlimg(String url) throws IOException {           Bitmap bitmap = null;           URL imageUrl = null;           String head = "http://114.80.209.134:13080/";           String tureUrl = head + url;           imageUrl = new URL(tureUrl);                      HttpURLConnection conn = (HttpURLConnection) imageUrl.openConnection();           conn.connect();           InputStream is = conn.getInputStream();           BufferedInputStream bis = new BufferedInputStream(is);           bitmap =            bis.close();           is.close();             return bitmap;       }

以前经常用这种方式获得图片，但是今天发现当图片比较多而且大时，经常失败，
后来发现 io流的获取没有出错，得到的是完整的io流，但是还是失败，发现是那个 BitmapFactory.decodeStream(bis);的问题后来改成这样，见下，可以完全解决问题。

private Bitmap getUrlimg(String url) throws IOException {           Bitmap bitmap = null;           URL imageUrl = null;           String head = "http://114.80.209.134:13080/";           String tureUrl = head + url;           imageUrl = new URL(tureUrl);             HttpURLConnection conn = (HttpURLConnection) imageUrl.openConnection();           conn.setRequestMethod("GET");           conn.setConnectTimeout(5 * 1000);           conn.connect();           InputStream is = conn.getInputStream();           byte[] bt = getBytes(is);           bitmap = BitmapFactory.decodeByteArray(bt, 0, bt.length);           is.close();           conn.disconnect();           return bitmap;       }              private byte[] getBytes(InputStream is) throws IOException {             ByteArrayOutputStream baos =new ByteArrayOutputStream();             byte[] b =new byte[1024];           int len = 0;           while ((len = is.read(b, 0, 1024)) !=-1) {               baos.write(b, 0, len);               baos.flush();           }           byte[] bytes = baos.toByteArray();           return bytes;       }
