I'm new to Android development and I am still learning. I'm trying to create a basic application to show bus route time of arrivals (simple text with a navigation drawer with bus routes).
I'm using Android Studio Navigation Drawer template for this.
It works on my HTC Desire (Bravo) API 10, but refuses to work on Huawei Media Pad 7 Lite (API 11).
This is the logcat

I have no idea how to properly detect on which line the error is, I read on a couple of places that I should look for "Caused" line, but it doesn't gives me a lot of information to work with or I don't know how to recognize them properly.
Any help would be appreciated, I tried searching all over the place but I can't find anything specific to my problem nor an explanation why it's happening.
On HTC Desire (API 10), logcat shows no errors.
If you need any source code please tell me to, I have no idea what to paste really, I'm still trying to catch up with it all and understand what everything is actually.
