App crashes with NullReferenceException, when setting MainPage

[wegascee]

Can't get this project working. It crashes on app start with "Object reference not set to an instance of an object". Seems the custom renderer is doing something wrong on a more up to date environment (XF 2.5.1.527436, Android 6 simulator).

I think this is the related log:

Seems that the style cannot be applied.

Now I changed the target framework to Android 6.0 and now it starts! (from Android 8)

Perhaps the VS 2015 is the reason for the cause. Here I have Android SDK Tools 25.2.5 installed, but newer version are not compatible. If someone runs in the same issue, he can lower the target framework.
