Its nothing but the Network on main thread exception; Just include

if (android.os.Build.VERSION.SDK_INT > 9) {
    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
    StrictMode.setThreadPolicy(policy);
}

to your code (in onCreate() method) and you’ll be fine 🙂
