I developed a React Native app, and I am using Expo Google-Sign-In for my Firebase authentication. I receive the error "DEVELOPER_ERROR" when I attempt authentication on my standalone APK on Android.
Initially, I was using "Expo Google", however that is now deprecated and my sign-in button did not do anything on my standalone APK. With Expo Google method, I found that I had to set the androidStandaloneAppClientId. Even after that, the sign-in got stuck at the Google homepage after authentication. I tried the solution of using a custom redirect URI, as in
redirectUrl: ${AppAuth.OAuthRedirect}:/oauth2redirect/google
but that resulted in another error: redirect_uri mismatch.
I switched to the Expo Google-Sign-In library instead, and that is giving me a DEVELOPER_ERROR every time I try to authenticate.
After that, I have tried:
- downloading the google-services.json and using it in my app
- setting the SHA1 fingerprint in google-services.json and in Firebase
- setting the certificateHash inside android.configuration.certificate hash inside my app.json to my SHA1 fingerprint.
- checking and making sure package names are set properly
I tried anything else I may have failed to mention from the existing threads involving DEVELOPER_ERROR in Expo Google-Sign-In.
The variables I mention in my code below are from the following:
SHA1 was generated and used to create my credential, and is the fingerprint used in my OAuth Android Client ID.
The client ID I reference throughout my files is the ID of my OAuth Web client ID. However, I also tried using the Android one and that did not change anything.
"CurrentKey" in api_key is the API key from my Firebase project.
