1. Go to android folder of your app.
2. Run ./gradlew clean

I met the same problem.
First delete build folder from project location (You can access it via android studio or using explorer), then build the project.

Answer 5

In case it helps someone, in my case I was using a custom package in release mode instead of in debug mode.

I just changed the package from "release" to "debug" and it worked.

Answer 6

In My case, I First Clean the project then i press Make Project button as below image, then it start working. Rebuild doesn't work for me.

And I also updating Google Repository is must.
