title: Ionic app crashes on Android emulator and device
body: <p>I'm building an app using the Ionic framework and AngularJS. It used to run fine, now it crashes as soon as it starts in both the emulator and an Android device. What is weird is that it runs fine in the Ionic View app (<a href="http://view.ionic.io/" rel="nofollow">http://view.ionic.io/</a>). The logcat says that the error is a NullPointerException.</p>
  
  <p>What really worries me is that I didn't do any big changes, and another app started to fail as well. How can Ionic Cordova fail like that?</p>
  
  <p>The complete logcat for the part of the crash says:</p>
