firebase로 구글,페북,이메일 로그인인증 만드는중 에러가 나요.2 [NullPointerException] [closed]

Question

googleLogin.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
    Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
                startActivityForResult(signInIntent, RC_SIGN_IN);
            }
        });

이부분에서 에러가 나는데요  이부분을 주석처리해도

emailLogin.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                createUser(editTextEmail.getText().toString(), editTextPassword.getText().toString());
            }
        });

loginButton.setReadPermissions("email", "public_profile");
        loginButton.registerCallback(mCallbackManager, new FacebookCallback<LoginResult>() {
            @Override
            public void onSuccess(LoginResult loginResult) {

                handleFacebookAccessToken(loginResult.getAccessToken());
            }

차례로 오류나서 다 주석처리하면 아무것도 실행이안되네요. 저것들 넣으면 앱이 죽어버리구요.

보면 버튼들만 오류가 나네요.

오류는 이렇게 나요. 3개다 하나씩 주석처리해도 다같은 오류 나오네요.

오류 해결좀 도와주세요 ㅜㅜ
