title: App works fine in android 2.3.7 and not in 4.1.2
body: <p>I have an app that works fine in android 2.3.4, 2.3.6 and 2.3.7 but it doesn´t in android 4.1.2 or 4.2.2 (I have no more devices)</p>
  
  <p>The app calls to a jar file that returns a result, when I test the app in 2.3.7 I make the call to the jar and takes the result but when I do it with android 4.1.2 it forces the close. It´s quite weird because the only difference is the OS because the app is the same.</p>
  
  <p>The jar file makes a call to internet, I don´t think this could be the mistake</p>
  
  <p>Thanks again everybody!</p>
