hi bro:
First there have GooglePlay FaceBook and Twitter SDK in my project.
so yesterday when i add FireBase SDK in my project,and add code to my project,like this:
Firebase.FirebaseApp.CheckAndFixDependenciesAsync().ContinueWith(kTask => { var eDependencyStatus = kTask.Result; Debug.Log("FireBase Init Success,status:" eDependencyStatus); m_bAvailable = eDependencyStatus == DependencyStatus.Available; });

so use gradle build the apk, run my game, the firebase did't work..
there have no log like FireBase Init Success,status:
also no any error log.

but
i create an empty project just add firebase sdk and build apk,the firebase work fine.

I think it is a problem caused by facebook sdk or googleplay sdk. but i don't know why!!

Unity: 2017.3.1f1
JDK:1.8.0_172
AndroidSDK:API Level 26

this is my plugins:

please help me.
thanks!
