To solve: Android4.0 after network connection is not allowed in the main thread behttp://www.2cto.com/kf/201310/248730.html Reply: This is very evident in the main thread for network operation caused.

You need this method into a new thread or HandlerThread execution. Or use AsyncTask, run doInBackgroud in.
