Crashes on Android after migrating to Unity 2018.3 when use AndroidJavaProxy class

Thank you for the lead!!! I had a VERY similar issue with my OnePlus 7 Pro and this helped direct me to the problem.

I did not have OpenGL 3 enabled, however for me is was actually Vulkan Graphics API causing the issue.

I noticed that it was Vulkan causing some issue after seeing it appear in crash errors in the Unity Cloud Diagnostics dashboard.

Like you said, I removed everything except for OpenGL 2 and FINALLY my OnePlus 7 Pro no longer insta-crashes on start up.

 

Hello everyone!
I faced the same issue in Unity 2021.3.17f1 after implementing Google Mobile Ads SDK. App crashes in several seconds on loading process completed.

So, I found two ways to fix it:

• Disable Strip Engine Code setting in Player Settings.
  Note: Changing value in Manager Stripping Level parameter doesn't affect anything.
• Add Android JNI package to your project. Just open Package Manager, find the package in Built-in list and install it.
