This is the updated version of godot-android-module-firebase for the new Godot (3.2.2) Android plugin system (v1).

For the general documentation look there.

• Open your project in Godot
• Install Export Templates if necessary
• Install Android build template
• Download from this repository's downloads directory both Firebase.release.aar and Firebase.release.gdpa and copy them to [GODOT-PROJECT]/android/plugins/
• Download from this repository's downloads directory godot-firebase-config.json and copy it to [GODOT-PROJECT]/android/build/assets (create the directory if necessary) and edit it to match your settings (especially AdMob App ID and ad unit IDs)
• Download your project's google-services.json from Firebase Console and copy it to [GODOT-PROJECT]/android/build/
• Edit [GODOT-PROJECT]/android/build/build.gradle:
  • add classpath 'com.google.gms:google-services:4.3.3' above the line //CHUNK_BUILDSCRIPT_DEPENDENCIES_BEGIN
  • add apply plugin: 'com.google.gms.google-services' above the line //CHUNK_GLOBAL_BEGIN
  • optional (for Authentication): search for buildTypes.all { and add to this block: resValue "string", "server_client_id", "project-123456..." where project-123456... is the public-facing name of your Firebase project
• Edit [GODOT-PROJECT]/android/build/AndroidManifest.xml:

  • add the following above the line <!--CHUNK_APPLICATION_BEGIN--> and do not forget to set your AdMob App Id

    <meta-data
        android:name="com.google.android.gms.ads.APPLICATION_ID"
        android:value="ca-app-pub-ADMOB_APP_ID"/>
    

• Edit [GODOT-PROJECT]/android/build/config.gradle and set minSdk to 21 (otherwise a gradle build error occurs: Number of method references cannot exceed 64K)
• In Godot select menu Project > Export, add Android and edit your settings (package unique name, keystores, etc.) and select under Custom Template: Use Custom Build and also under Plugins: Firebase.

That should be it!

After checking out this project open Android Studio and start an empty Android project (with no activity, minimum SDK 21). Then select menu File > New > Import module and import this project as a module. In the Android Studio's terminal you can then run:

• gradlew clean
• gradlew build

When finished the .aar for both debug and release can be found here: build/outputs/aar
