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 :)

  • Strict mode is a method of avoiding network actions in main thread; introduced from 3.0 Honeycomb; the code just tells if the target version is above froyo, it'll turn off strict mode:) – Manoj Kumar Sep 13 '12 at 08:07
  • i change 9 (num that you write on code) to 8, is it problem? btw is it code safety and no effects? – oyiym Sep 13 '12 at 08:22
  • thanks, dude :). btw do you understand about blackberry programming? – oyiym Sep 13 '12 at 08:52
  • unfortunately i've played with only Android and ios for now; will learn it soon:) sorry for now – Manoj Kumar Sep 13 '12 at 09:28
  • The correct solution is to **get the networking code off the main application thread**. This "solution" is merely burying one's head in the sand. – CommonsWare Sep 21 '12 at 12:03
