Cannot get project to load past Launch screen on Android Device on 4.22.2

Things I’ve done:

  1. Installed all available SDK’s
  2. Accepted android sdk license agreement
  3. Added all of the correct directories required on the SDKConfig Android SDK tab
  4. Set the lowest Android build to 9, target build to 26 (Which is 8.0 oreo, the OS my tablet is running)
  5. Ran cmd + adb devices
  6. “Verified” the UE 4.22 build
  7. Installed a previous engine of UE (4.21.2), and tried launching from that (wouldn’t load 4.22.2 map)
  8. Tried launching different projects to the device under 4.22.2 (failed)
  9. Tried launching different new projects to the device under 4.21.2 (WORKED)
  10. Tried launching a much older backup of the same project (4.19.2) under 4.21.2. (WORKED)

Unreal engine 4.22.2 is able to detect my tablet. It builds the project, and loads it into the tablet, however, it will not under any circumstances load past the “Launch portrait” or “Launch landscape” screen whilst launching from the 4.22.2 build.

I’ve googled for a couple of hours trying to find anywhere mentioning my specific problem, and can’t find anything about anyone experiencing something similar.

I suspect a bug since everything is launching without issue from 4.21.2 and not 4.22.2 using identical settings.

Anything I can do to help fix this problem if it’s an engine bug?

If it is not an engine bug, anything I can do to address it on my end?

Try running monitor.exe, should be somewhere in the android files. That should give you the error you get. For me I enabled a plug-in that froze the game. Check if you enabled a plug-in by mistake or a plug-in enabled in the new version and wasn’t disabled or compiled.

By load do you mean it freezes at the launch screen? or it doesn’t load and shows you an error?

Hey! Thank you for that suggestion. I uninstalled Datasmith, and building from 4.22.2 now works!

Thanks a ton. :slight_smile:
