App works on emulator but crashes on android(5.1.1)

I have followed Ionic basic tutorials and tried to run the app on emulator, it worked but while deploying on android real device (5.1.1), it launches and then crashed. Following is logcat:

Help is appreciated.

P.S.: I have used tabs example, blank as well as conference tutorials. I didn't test on iphone, only on android device(5.1.1). Not sure about other android versions.

Thanks.
