        conn.setConnectTimeout(5000); 
        is = conn.getInputStream();
        byte[] imgbytes = StreamTool.getBytes(is);
        imgmap = BitmapFactory.decodeByteArray(imgbytes, 0, imgbytes.length);

    } finally {
        if (is != null) {
            is.close();

    return imgmap;
}

before conn.setRequestMethod("GET") was excuted,thorws the exception Connection already established. who can give me a solution

Answer 1

I know it is completely nonsense. But it happens for me in debug mode when I put break point on this line.

con.setRequestMethod()

As soon as I removed the break point, the error has gone!
