Answer 1

This way you can login user with email and password and retrieve id:

FirebaseAuth.getInstance().signInWithEmailAndPassword(email,password).addOnSuccessListener(new OnSuccessListener() {
          @Override
          public void onSuccess(AuthResult authResult) {
              FirebaseUser user = authResult.getUser();
          }
      });
