Hi

I have problems to build and start the plugin on android. When I use the plugin inside a clean unity project, it works fine, but when I copied the plugin inside my current project, I can't start the app. I have the following error message on android log: `08-23 16:14:32.576 3706-23106/?

08-23 16:14:32.757 3706-2103/? W/ActivityManager: Force finishing activity com.test.unity/com.bkmin.android.UnityPlayerNotOnTopActivity`

Has anyone an idea what I do wrong? When I export the unity project as android project, the jar file was not exported. Is that correct? (I found some similar problem here: https://forum.unity3d.com/threads/classnotfoundexception-on-android-plugin.182482/)

And I use vuforia, could that be the problem? When I don't override UnityPlayerNativeActivity in Manifest.xml, then it works, but the next problem is this one: https://github.com/YousicianGit/UnityNativeEdit/issues/44

Thank you

I think it shouldn't be necessary anymore to use the UnityPlayerNotOnTopActivity workaround as Unity apparently rolled back the stuff that caused the issues that that workaround was fixing. We should update the readme.
