App crashing using @capacitor-firebase/authentication

[davebanguilan]

Hi, do you guys have a short video in implementing the firebase authentication? My app somehow crashes when implementing your package. I can't open the application but I manage to see the error in Android Studio. I followed your procedure in the authentication demo. I setup my firebase project and added the apiKeys in my environment.

Unfortunately, no. Maybe this community guide helps you: https://github.com/basvdijk/capacitor4-firebase-analytics-example-project-capawesome-team
It is for Analytics but the part for the setup of Firebase is the same.

Hi @robingenz. I was able to set it up properly. Thank you for the link.

@robingenz @davebanguilan My app is on react, capacitor and firebase. My app gets deployed to Android device with no problem.
Then I have made No Code Change at all and I just installed the plug-in @capacitor-firebase/authentication and tried to deploy again on same Android device and it fails with below error.

Web based application continues to work fine.

Also saw the demo app based on Angular but couldn't figure out what am I missing. Could you please help here?

You need to follow the installation instructions and setup Firebase correctly, see https://firebase.google.com/docs/android/setup

[rapsalands]

@robingenz Thanks. I will look at the docs again.

But as I mentioned, without this plugin installed I am able to run my app on Android device without any issue including phone authentication. So, I was assuming my firebase setup is already right and issue is with plugin.

[robingenz]

When you install this plugin you also have to setup Firebase correctly because it's a Firebase plugin. And this error only occurs if the setup is not correct. I need a minimal reproducible example to help you further.

@robingenz Following the link you posted, I am able to make it work. Thanks a lot.

Make sure SHA1 of your debug signing and production signing is uploaded to firebase.
