starting from 2019.3.b4+, there is an updated Android example Integration Unity as a library in native Android app Version 2 that should work.

older example works in a range [2019.3.a2+ to 2019.3b4)

make sure to include in the build.gradle(Module :app)
implementation fileTree(dir: project(':unityLibrary').getProjectDir().toString() + ('\\libs'), include: ['*.jar']

for me on Ubuntu
implementation fileTree(dir: project(':unityLibrary').getProjectDir().toString() + ('/libs'), include: ['*.jar']
and change “\” to “/” in
project(':unityLibrary').projectDir=[new](http://www.google.com/search?q=new+msdn.microsoft.com) File('..\\UnityProject\\androidBuild\\unityLibrary')
this worked.
