Cordova-plugin-firebasex: Buid failed with plugin @mauron85/cordova-plugin-background-geolocation

[ekohadim]

After added the plugin, build failed and investigated for a day, i finally found that this plugin doesn't work with plugin @mauron85/cordova-plugin-background-geolocation. If i removed one of either cordova-plugin-background-geolocation or firebasex, it built successfully.

Below is the error message. Appreciate if you could guide me what i should do. Thanks.

I reported the issue too soon, i found it on their git issues, and it has already discussions about this issue. Found the solution, just install cordova plugin add cordova-android-play-services-gradle-release. And it works now. Thanks.
