Hello, I have the exact same problem:
The app crashes on android either instantly or shortly after the splash screen is shown:
- I have tried various versions: 4.20-4.22. Note that 4.19 does work for me! But the problem is the AR Core plugin in there is a really early one, there is no image recognition (augmented images) for example.
- I have tried various Samsung devices (S7 and Tab S3) the same result.
- I tried reinstalling NV pack, nothing
- Tried the UE4 source version forked by Google that is on their github repo, same result.
By the way I also could not deploy with Gradle, it keeps moaning about not having accepted all SDK licences, which is not true. I also used Ant.
I obtained the logcat and it says "UnsatisfiedLinkError: dlopen failed: library “libarcore_sdk_c.so” not found.
Have you checked your logs?
I have wasted 10 hours looking for a solution, would be pretty neat if somebody had an idea.
