I want to use both Firebase Auth and Firebase Admin dependency in my project. So i have added below dependency 

implementation 'com.google.firebase:firebase-auth:19.2.0'
implementation 'com.google.firebase:firebase-admin:6.12.2'

But i can't use below method from firebase auth

FirebaseAuth.getInstance().getCurrentUser();
FirebaseAuth.getInstance().signOut();

I can only have methods of FirebaseAuth from firebase-admin dependency. Some available methods are:

FirebaseAuth.getInstance().getUser(uid);
FirebaseAuth.getInstance().deleteUser(uid);

If i remove firebase-admin dependency I can use getCurrentUser, signOut and other methods from firebase-auth

Its like both dependency have same package FirebaseAuth class with different implementation. With some search i found that firebase-admin is for server side.

Is that means i can't use firebase-admin and firebase-auth in same project?

How can is use both in my project?

Give me some suggestion for this situation.

Thanks in advance.

The Firebase Admin SDK is not intended for use in Android apps. It's for backend code running in a controlled server or desktop that you fully control. Please don't try work around this - instead your Android app should be invoking a backend that uses the Admin SDK to perform the work you need. It would be a fairly massive security hole for an app to have the Admin SDK and a service account bundled into it, as that leaves your project open to direct, easy abuse by anyone who can download your app and get the service account credentials.
