Question

I was stuck in my first real-time firebase application. :( I was making a simple logging application using firebase, but I found a runtime error. Please Remember that I am using Android Studio 2.3 .

Note. . I included google-services.json also in the required directory.

Error

My project level gradle file

Note: - I think this problem may be ----> "because of my sdk manager. But I don’t know how I check which sdk files are required for android studio 2.3 working with firebase".

                                   or,

gradle firebase-auth/firebase-core. , : -

, .   :)
