Unable to get provider com.google.firebase.provider.FirebaseInitProvider: java.lang.IllegalArgumentException: Given String is empty or null

• Cause: This error is typically thrown when Firebase cannot find a given configuration string in your google-services.json file.
• Solution: If your project already has a google-services file at gnd/debug/google-services.json, clean the project, then rebuild it (in Android stuido, select Build > Clean Project). This should resolve the issue. If you don't have a gnd/debug/google-services.json file, follow the instructions in CONTRIBUTING.md to set up firebase.

Room cannot verify the data integrity. Looks like you've changed schema but forgot to update the version number. You can simply fix this by increasing the version number.

• Cause: This error occurs when the database has changed but its version number has not been updated.README
• Solution: Increase the value of the DB_VERSION field in gnd/src/main/java/Config.java.
