Add Firebase to your Android app

Register your Android app

Open the Project Overview page in your Firebase project and launch the setup workflow via the Android icon ().

Add Android app to Firebase project

If you've already added an app to your Firebase project, click Add app to display the platform options.

Next, you need to provide various information about your app.

Register Android app in Firebase project (Register app)

Enter the following details and click Register app:

  1. Android package name: The package name of your Android app (e.g. com.example.myapp) as defined in the capacitor.config.ts file:

    capacitor.config.ts

    import { CapacitorConfig } from '@capacitor/cli';

const config: CapacitorConfig = {
    appId: 'YOUR_APP_ID',
};

export default config;

  2. App nickname: A nickname for your app (e.g. My App).

  3. Debug signing certificate SHA-1: The SHA-1 fingerprint of the signing certificate used to build the debug version of your app. You can find it by running the following command in the root directory of your app:

    keytool -list -v -alias androiddebugkey -keystore ~/.android/debug.keystore

    The default password for the debug keystore is android.

    The output should look like this:

    Copy the SHA-1 fingerprint and paste it into the Firebase setup workflow.

The next step is to download the google-services.json file and move it into the android/app directory of your app.
