Hello. I’ve created simple project in editor, it works fine in editor and standalone package for windows, but i can’t deploy it on any Android device. When i tried to package it with any texture formates and install it on my devices, after launching app i see black screen and few seconds it shutdown without any messages. Launching from editor doesn’t work too, it wrote “Launch successfully” or something like that, but app is still crashing. Here is example from log after “success” launch from editor (can’t post whole log because of spamming LogWindowsTextInputMethodSystem errors):

LogWindowsTextInputMethodSystem:Error: Deactivating a context failed while setting focus to the disabled TSF document manager.

I tried to package examples from Epic, and it works strange too. Lightroom demo works on Galaxy S3, but still crashed on Optimus 4X HD and other devices.

I’m having the same issue with my APK. It has built just fine in distribution and develoopment, runs fine in PIE and mobile preview but I’m having the same issue as InquisitorAles, where the app opens, i see the splash screen, then it goes black and crashes fatally to the devices desktop.

I’m experiencing this problem too, it’s really frustrating as I’ve tried so many different methods that have been posted on AnswerHub with very little success though :frowning:

I used the Android Device Monitor and this was the log I got from it if anyone can see what is happening during runtime?

Bumping for a response as I’m at a complete blocker with this now :confused:
