This Error is solved by putting PlayerServices and Firebase plug-in files in Unity's Plugin folder.

Unity Code

public class TestCode : MonoBehaviour {
AndroidJavaClass andClass;
AndroidJavaObject andObj;
void Start () {
        andClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
        andObj = andClass.GetStatic<AndroidJavaObject>("currentActivity");
}
}

MainActivity.java

public class MainActivity extends UnityPlayerActivity {
private static MainActivity instance = null;

public static MainActivity getInstance() {
    if(instance == null) {
        instance = new MainActivity();
    }
    return instance;
}

@Override
protected void onCreate(Bundle bundle) {
    super.onCreate(bundle);
    FirebaseApp.initializeApp(this);
    Log.d("unity", "StartActivity");
}
}

Another Code looks like this code.

Call funcion is Success. but Call FirebaseInstanceId.getInstance().getToken() cause error. — Bonifacius, Apr 03 '18 at 08:09
That's not error. Obtain the error log from adb. It should show the real error there and they are usually in red text. See [this](https://stackoverflow.com/questions/44690357/how-to-create-and-read-log-on-android-devices/44690501#44690501) for that. Without that, no one can help you. — Programmer, Apr 03 '18 at 09:41
Yes. That't it. Now you have to copy it as a text into your question and format it as a code or quote so that it can be easily read. I think that the problem is that it's not including the firebase plugin you are referencing in your Java plugin. You need to find that firebase plugin (.aar or jar) and also include it in your Unity Assets/Plugins/Android folder so that it will be included in the build. That should fix your issue but another problem may come out. I will be away for hours but will see where you stopped when I return. — Programmer, Apr 03 '18 at 12:11
