Can anyone tell me what may be the cause of the problem?
Thanks in advance.

I can give you a few things to try. From what I know this error is caused by your NDK API Level. For me, this error was solved when I set the NDK API Level to Android-19/Android-21. Also, tick the full rebuild option in the Packaging section.

If in case you have nativization on, turn it off and then package. Also,

If you can get your project onto the device, please provide your logcat files from the logs:

Attach your phone to the computer

Open NVPACK\android-sdk-windows\tools

Startup Monitor.bat as administrator

Create a filter for your Application

Launch the program and save the logs

Hmm. Does the map load properly inside the editor? Also, try this -

Add all your maps in this array

That worked perfectly and the games launches now. However there’s another problem now. My maps aren’t getting loaded. When I press a button that should open another map the app just closes. It doesn’t crash it just closes so I’m assuming it the map was packaged properly. Any advice on this?

Yes the maps do load inside the editor. I tried what you suggested but it still did not work.

I’m afraid that I need more information then, like how your Map is how you try to load it and also if your game is closing on the device, you should still run Monitor.bat to generate logs and find out what exactly is causing the app to close. Might be better to make a new question.
