Problems on android 5.1.1

Hi all,

A little help if possible.

I've run my app, on the genymotion emulator using a 5.1 device, works fine. I have two tablet one using 4.2 and I think the other uses 4.4 both work.

The app works on iOS also.

However I get the following error on a friends phone (sony z3) using 5.1.1

Any ideas on a fix?
