Hope that helps I want to get the exceptions caused when a user fails to log into my app using Google Sign in. For example, in the handleSignInResult(@NonNull Task completedTask) method I use this: , This is what I should use:
code :
private void handleSignInResult(@NonNull Task<GoogleSignInAccount> completedTask) {
    try {
        account = completedTask.getResult(ApiException.class);
        if(isSignedIn()) {
            Toasty.success(this, "Success!", Toast.LENGTH_SHORT, true).show();
            startActivity(new Intent(MainActivity.this, Home.class));
    } catch (ApiException e) {
        if(e.getCause() != null) {
            Toast.makeText(this, "Failed to login because: " + e.getCause(), Toast.LENGTH_LONG).show();
        else {
            Toast.makeText(this, "Failed to login because: No account Selected!", Toast.LENGTH_LONG).show();

help you fix your problem Ok, I've found the POST I can use in the C# web project (/POST/ExternalLogin). There I also see what I should send:
In the header:
code :
public class TaskPostAPI extends AsyncTask<String, Void, String>
    private String TOKEN = "__RequestVerificationToken";

    protected String doInBackground(String... urls){
        String response = "";
        for(String url : urls){
            HttpPost post = new HttpPost(url);
                // Add the default Content-type to the Header
                post.addHeader("Content-type", "application/x-www-form-urlencoded");

                // Get the baseUrl from the given url
                URL u = new URL(url);
                String baseUrl = u.getProtocol() + "://" + u.getHost();

                // POST-request requires anti-forgery Cookie
                // Get all Cookies
                CookieManager cookieManager = CookieManager.getInstance();
                String cookie = cookieManager.getCookie(baseUrl);
                String[] cookies = cookie.split(";");

                // Put all Cookies in a HashMap with cookieKey & cookieToken
                HashMap<String, String> cookieStrings = new HashMap<String, String>();
                for(String cook : cookies){
                    String[] cs = cook.split("=");
                    cookieStrings.put(cs[0], cs[1]);

                // Add the Cookie to the Header
                post.addHeader("Cookie", TOKEN + "=" + cookieStrings.get(TOKEN) + "");

                // POST-request requires cookieToken, provider and returnUrl
                List<NameValuePair> nvPairs = new ArrayList<NameValuePair>(3);
                nvPairs.add(new BasicNameValuePair(TOKEN, cookieStrings.get(TOKEN)));
                nvPairs.add(new BasicNameValuePair("provider", "Google"));
                nvPairs.add(new BasicNameValuePair("returnUrl", baseUrl));
                post.setEntity(new UrlEncodedFormEntity(nvPairs));

                Log.i("COOKIE OUTPUT", TOKEN + "=" + cookieStrings.get(TOKEN) + "");

                // Send the POST-request
                HttpResponse execute = MainActivity.HttpClient.execute(post);

                // Get the response of the POST-request
                InputStream content = execute.getEntity().getContent();
                BufferedReader buffer = new BufferedReader(new InputStreamReader(content));
                String s = "";
                while((s = buffer.readLine()) != null)
                    response += s;
            catch(Exception ex){
        return response;
Android app Facebook Sign-In remembers user, but Google Sign In doesn't

Android app Facebook Sign-In remembers user, but Google Sign In doesn't

I hope this helps you . So I've implemented Facebook sign-in, now I've implemented Google. It signs in successfully, but when I restart the app, the user has to log in again. If I log in with FB however, it does as it should. Here's my AuthListener: , I solved it myself. I was missing the firebaseAuthWithGoogle method:
code :
private void firebaseAuthWithGoogle(GoogleSignInAccount acct) {
    Log.d("AD", "firebaseAuthWithGoogle:" + acct.getId());

    AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
            .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                public void onComplete(@NonNull Task<AuthResult> task) {
                    Log.d("AD", "signInWithCredential:onComplete:" + task.isSuccessful());

                    // If sign in fails, display a message to the user. If sign in succeeds
                    // the auth state listener will be notified and logic to handle the
                    // signed in user can be handled in the listener.
                    if (!task.isSuccessful()) {
                        Log.w("AD", "signInWithCredential", task.getException());
                        Toast.makeText(SignUp.this, "Authentication failed.",
                    // ...
if (result.isSuccess()) {
            // Signed in successfully, show authenticated UI.
            GoogleSignInAccount account = result.getSignInAccount();

Hope that helps Why don't you save the google sign-in token in your local database and every time the user opens the application make a check for the user token (maybe in your splash) and if it is present it means there is already an existing user make an intent to the profile activity. Else personal-details activity.

fixed the issue. Will look into that further You also need to sign out from GoogleSignInClient and FirebaseAuth current user, something like this:
code :
 //sign out of the user and start login activity.
public void signOut() {
    signOutBtn.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {
            GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
           GoogleSignInClient mGoogleSignInClient = GoogleSignIn.getClient(getContext(), gso);
           startActivity(new Intent(getContext(), LoginActivity.class));
