HttpUrlConnection的setDoInput(),setDoOutput()

今天头脑有点蒙。做一个listview图文混排的例子，用AsyncTask

conn.setDoInput(true);conn.setDoOutput(true);

然后运行后报错。

    public Bitmap downLoadImage() {            Bitmap bitmap = null;            HttpURLConnection conn = null;            try {                URL url = new URL(imageUrl);                conn = (HttpURLConnection) url.openConnection();                //这里可以不设置他们                //conn.setDoInput(true);                //conn.setDoOutput(false);   setdoinput(true),setdooutput(false);                conn.setReadTimeout(8000);                conn.setReadTimeout(10*1000);                InputStream is = conn.getInputStream();                bitmap = BitmapFactory.decodeStream(is);            } catch (Exception e) {                e.printStackTrace();            }            return bitmap;        }

这里写代码片
