I submitted an app package name to the Google Developer Console for verification and allow sideloading and distribution through other channels. As part of the verification process, they wanted me to create a new file adi-registration.properties under /app/src/main/assets, similar to the structure shown here. Thereafter, I had to create and sign an apk with the same key whose SHA 256 I had uploaded earlier, and submit that apk for verification.

The instructions did mention that I can do this in the main app, or just a dummy app with the same package name. Therefore, the question arises — should I commit this file in git, given that my app will probably be an open-source app soon?
