You need to add android.enableUnitTestBinaryResources=true to your gradle.properties unless you are using build tools 3.4 then there is no need.

You need to add android.enableUnitTestBinaryResources=true to your gradle.properties unless you are using build tools 3.4 then there is no need.

I still see this warning using AGP 3.5.2.
Note: I have not set android.enableUnitTestBinaryResources=true
