My BlogReader app is crashing 8 times in 10 launches and the LOGCAT shows NullPointer Exception and JSONException.

The point is that the json content is probably not being properly parsed as it shows some weird question mark like characters. Also the app crashes only 80%times and crashes only when active network is present. The app also crashes when the screen orientation changes. Thanks in advance.
