While I was using 4.15.2 the game ran on mobile fine but after I upgraded to project to version 4.16.1 the game crashes when I launch it to android mobile. It just flashes a black screen then shows “Unfortunately the app has stopped”. As I said this problem didn’t happen on 4.15.2. I tried to roll the game back to 4.15.2 but that didn’t fix the problem. Can someone kindly help me with this problem. Here is the output log if this is of any help. link text

Edit: Also when I play in editor the materials are really weird. For example the ones that emit light are really really bright now and some of them just don’t work now. Maybe that could be the cause of the previous problem.

So where do I get the correct log from?
And I’m sorry but I’m not sure what that is. Is it a setting?

correct log you can get only from device.

android works is a software, that contains android sdk, ndk, and so on. ue 4.16 works only with android works R6.

This log is from editor.

Do you use android works R6？

These are the settings I have for android sdk.
I installed android gameworks by going to this directory “C:\Program Files\Epic Games\UE_4.16\Engine\Extras\AndroidWorks\Win64” and I clicked CodeWorksforAndroid-1R6u1-windows and followed the steps and it still crashed
