Frequently Asked Questions

How do I fix the 'Failed to create Firebase Application' runtime crash?

This occurs when configuration assets are missing. Ensure google-services.json (Android) or GoogleService-Info.plist (iOS) are saved in your project's Config/Firebase directory so the build tool packages them properly.

Why am I seeing Android NDK linker errors during gradle compilation loops?

This happens when conflicting plugin layers import duplicate Firebase dependencies. Our plugin uses an isolation layer inside its Android_UPL.xml file to resolve dependencies cleanly without manual code hacks.

How do I resolve CocoaPods workspace compilation failures on macOS builds?

Ensure your machine has Ruby and CocoaPods installed. Run the packaging pipeline from the Unreal Editor to allow the plugin's automated script to generate and link the target Xcode workspace structures.

Can I test my game's Firebase integration inside the Unreal Editor without packaging?

Yes. Unlike basic wrappers that only function on target mobile devices, our plugin includes precompiled desktop binaries, enabling full database and auth testing directly inside the editor viewport.

How do I fix bitcode or architecture mismatch errors in Xcode?

Our plugin pre-configures custom target xcframeworks that strictly exclude legacy bitcode lines and include native arm64 support, bypassing the typical manually updated framework linking errors completely.

What should I do if Proguard or R8 strips Firebase classes during Android release packaging?

The plugin ships with integrated custom Proguard rule declarations embedded right within its configuration files, keeping necessary native callback endpoints intact automatically for shipping builds.
