Android: com.google.firebase.auth.FirebaseAuth.signInWithEmailAndPassword gives exception as on a null object reference

[amo222lpatil]

On android I'm using:

TiSDK 7.2.0.GA
firebase.core 2.2.0
firebase.auth 1.0.1
ti.playservices 11.0.40
hyperloop 3.0.5
Alloy project

index.js
var Firebase = require('firebase.core');
Firebase.configure({file:"google-services.json"});
var FirebaseAuth = require('firebase.auth');
FirebaseAuth.signInWithEmail({
email : '[e-mail]',
password : '********',
callback : function(e) {
Titanium.API.trace("[index] >> in callback funtion ");
if (!e.success) {
Ti.API.error('Error: ' + e.error);
return;
}
Ti.API.info('Success!');
Ti.API.info(e.user);
}
});

It gives error as
[ERROR] : TiExceptionHandler: (main) [0,130] - Message: Uncaught Attempt to invoke virtual method 'com.google.android.gms.tasks.Task com.google.firebase.auth.FirebaseAuth.signInWithEmailAndPassword(java.lang.String, java.lang.String)' on a null object reference

Missing environment, example code and any other notes. This is not how issues work, sorry.
