Rare Nullpointerexception In Googleapiclient Using Firebase

I am using GoogleApiClient to login users using their Google account. Basically, I am using Firebase Auth with Google sign in. But I am getting this crash on some devices every sin

Solution 1:

Hello You can try this code this is a working code in my project first initialize google api client in on create

publicvoidinitGPlus() {
    GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestEmail()
            .build();
    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .enableAutoManage(this/* FragmentActivity */, this/* OnConnectionFailedListener */)
            .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
            .build();
}

and on the button click call another function

IntentsignInIntent= Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
    startActivityForResult(signInIntent, RC_SIGN_IN);

In On Activity result just got your response and handle that result in a function

if (requestCode == RC_SIGN_IN) {
        GoogleSignInResultresult= Auth.GoogleSignInApi.getSignInResultFromIntent(data);
        handleSignInResult(result);
    }

implement this interface in your activity

implementsGoogleApiClient.OnConnectionFailedListener

Solution 2:

While checking for Google Play services would be good, I think this may be due to a device having an old version of Google Play services.but that's not a great error regardless.
