Google sign in not working android?

So an issue my project has encountered is that the sign in through google does not work consistently. Ie, it works for my friend and not me from my computer, even though it worked for me yesterday before wiping my phone (phone got corrupted). Our login code is the standard for google sign in, and the problem is that the result keeps returning false I think. the code:

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.welcome_screen);
        findViewById(R.id.sign_in_button).setOnClickListener(this);

        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();

        SignInButton signInButton = (SignInButton) findViewById(R.id.sign_in_button);
        signInButton.setSize(SignInButton.SIZE_STANDARD);
        signInButton.setScopes(gso.getScopeArray());

    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.sign_in_button:
                signIn();
                break;
        }
    }   

private void signIn() {
        Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
        startActivityForResult(signInIntent, RC_SIGN_IN);
    }

    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        // Result returned from launching the Intent from GoogleSignInApi.getSignInIntent(...);
        if (requestCode == RC_SIGN_IN) {
            GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
            handleSignInResult(result);
        }
    }

    private void handleSignInResult(GoogleSignInResult result) {
        if (result.isSuccess()) {
            // Signed in successfully, show authenticated UI.
            GoogleSignInAccount acct = result.getSignInAccount();

//            mStatusTextView.setText(getString(R.string.signed_in_fmt, acct.getDisplayName()));
            updateUI(acct);
        } else {
            // Signed out, show unauthenticated UI.
            noUpdateUI();
        }
    }

    private void updateUI(GoogleSignInAccount acct) {
        Intent intent = new Intent(getApplicationContext(), HomeScreen.class);

        Bundle bundle = new Bundle();
        bundle.putSerializable("NEW_USER", new ClientUser(acct));
        intent.putExtras(bundle);

        startActivity(intent);
    }


For some reason, the result is false:

    private void noUpdateUI() {
        System.out.println("**** Try again****");
//        mStatusTextView.setText(R.string.signed_out);
        findViewById(R.id.sign_in_button).setVisibility(View.VISIBLE);
    }

I think I have set up my app's credentials correctly, as it worked previously from my desktop before I wiped my phone. Of note, my friend had the same issue working from his laptop, but does not have the issue working from his desktop. Not sure what's up; any suggestions?

I had the same problem. I solved it by doing the following:

I went to my build.gradle(app), inside defaultConfig and changed the applicationId to my package name (I dont know why it wasnt the same initially). I switched from compile 'com.google.android.gms:play-services-auth:8.3.0' to compile 'com.google.android.gms:play-services-auth:8.4.0' Make sure apply plugin: 'com.google.gms.google-services' is at the bottom of your build.gradle(app) i.e after the dependencies
I generated a new SHA-1 key. To generate SHA-1 key paste this in your terminal: keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android then go to your credentials page and select your project.
under OAuth 2.0 client, click your android client key. paste the SHA-1 key you generated and your package name as directed. click save.
1. download a new google-services.json file and paste it into your app/ directory.

Then try signing in again. Hopefully it should work. For more info, see this post and this as well. It helped me solve mine

You need to attach your android client key when creating GoogleSignInOptions like this

  signInOptions = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN).
            requestScopes(new Scope(Scopes.EMAIL)).
            requestEmail().
            requestIdToken(getString(R.string.client_id)).
            build();

I had to downgrade from play-services-auth 16.0.0 to

implementation 'com.google.android.gms:play-services-auth:15.0.1'

And then it worked.
