I have an app that runs absolutely fine when I build it using the debug keystore. For the first time, I made a signed APK for release on Google PlayStore. I transferred the signed apk to my phone via the USB cable, installed the app and now when I try to run it, it crashes. It crashes right when I try to open it. 

I have crash reporting enabled via Crashlytics and that doesn't report any new crashes either. 

When I build it from Eclipse and run it, it all runs fine.

Where do I look for the problem? 

Logcat when the app crashes:

```
