Integrating Google Sign in button in Android App

Question

Okay i was trying this code from Google https://developers.google.com/identity/sign-in/android/sign-in?configured=true

LoginActivity

GoogleApiClient mGoogleApiClient;
GoogleSignInOptions gso;
SignInButton signIn_btn;
private static final int RC_SIGN_IN = 0;
ProgressDialog progress_dialog;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);


    buidNewGoogleApiClient();
    setContentView(R.layout.activity_login);
    customizeSignBtn();
    setBtnClickListeners();


    mNotificationManager = (NotificationManager) this.getApplicationContext().getSystemService(this.NOTIFICATION_SERVICE);

    Typeface myTypeFace = Typeface.createFromAsset(getAssets(), "Big Daddy St.ttf");
    Typeface myTypeFaceFacebook = Typeface.createFromAsset(getAssets(), "Big Daddy St.ttf");


    mainImage = (ImageView) findViewById(R.id.imageView1);

    TextView textView1 = (TextView) findViewById(R.id.textView1);
    textView1.setOnClickListener(this);
    textView1.setTypeface(myTypeFace);

    Button button = (Button) findViewById(R.id.btn_login_facebook);
    button.setOnClickListener(this);
    button.setTypeface(myTypeFaceFacebook);



}

apply plugin: 'com.google.gms.google-services'

Your help will be much appreciated.

Edit: Added GoogleSignInStatusCodes.getStatusCodeString(result.getStatus().getStatusCode()); which returns 10, corresponding to DEVELOPER_ERROR.

I had previously created a key for Google Maps, which is included in my Project (In Manifest file, meta tags), now do I have to create another Key? If yes, how do I include it?

What do you want to achieve? What should be the steps your program takes? — Flummox - don't be evil SE, Nov 06 '16 at 10:20

To debug this, I would do this: breakpoint / print to log what you get back from Google on success login. That will tell you where the data is what you want.

What is the next Activity? Looks like you are starting something from Google, but it would make more sense to start something of your own making.

edit went over it. Some thoughts:

googleSignInButton = (SignInButton) findViewById(R.id.sign_in_button);
findViewById(R.id.sign_in_button).setOnClickListener(this);

// Can be done this way:
googleSignInButton = (SignInButton) findViewById(R.id.sign_in_button);
googleSignInButton.setOnClickListener(this);

And this is how I have done something like it:

SignInButton buttonGoogle = (SignInButton) findViewById(R.id.button_google);
assert buttonGoogle != null;
buttonGoogle.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
        startActivityForResult(signInIntent, RC_SIGN_IN);
    }
});

And to handle a Successful login from Google you will need something like this: getResources().getString(R.string.google) => Getting a string from the strings.xml

/**
 * Handling the result from Google.
 * @param result                    You know, tha package.
 */
private void handleSignInResult(GoogleSignInResult result) {
    Log.d("handleSignInResult:", "" + result.isSuccess());
    if (result.isSuccess()) {
        // Signed in successfully, show authenticated UI.
        GoogleSignInAccount acct = result.getSignInAccount();
        successfulLogin(getResources().getString(R.string.google),
                acct.getDisplayName(),
                acct.getId(),
                acct.getEmail());
    } else { // but is never used atm.
        String message = String.format(getResources().getString(R.string.communication_signed_out), getResources().getString(R.string.google));
        Toast.makeText(getApplicationContext(), message, Toast.LENGTH_SHORT).show();
    }
}

I use oauth 2 to sign in Google by Webview. If you an example...I will post for you. – Almeida Nov 06 '16 at 12:31
Thank you for that, but can you see what is wrong in the above code? – AIS Nov 06 '16 at 12:37
Added some code that might help. This works with me. Hope you understand how it works. – Flummox - don't be evil SE Nov 07 '16 at 08:41
Let me try and get back, where are you starting a new activity on successful sign in? – AIS Nov 07 '16 at 14:17
if (result.isSuccess()) is what runs if you successfully log in. Use Toast of System.out.print("Succes"); to see if it gets there. If not, you will see a toast. – Flummox - don't be evil SE Nov 07 '16 at 14:22
what is successfulLogin()? – AIS Nov 07 '16 at 18:22
Okay, made changes to the code as you suggested, result was the Toast string in 'communication_signed_out'.So did not login. Now I am uninstalling the app from device and running again...and still cannot login..Toast same as 'communication_signed_out'..see updated code – AIS Nov 07 '16 at 18:49
Log.d("handleSignInResult:", "" + result.isSuccess()) is false – AIS Nov 07 '16 at 18:55
That means your login failed: you did **not** login. Recommended: create a Google test account with a simple password so you know that the login went successful. – Flummox - don't be evil SE Nov 07 '16 at 20:28
Why isn't my current google account working? It is valid. – AIS Nov 08 '16 at 08:09
I have no idea why that should not work. Makes no sense really. That's why it is an idea to check with an other account. The code that I gave you works in my app. Other than this, I have no idea why it does not work on your side. – Flummox - don't be evil SE Nov 08 '16 at 08:44
Could there be something with json file? I pasted that file in app directory – AIS Nov 08 '16 at 12:14
Why do you need a JSON file? – Flummox - don't be evil SE Nov 08 '16 at 12:31
Following this https://developers.google.com/identity/sign-in/android/sign-in?configured=true, adding google-services.json file. – AIS Nov 08 '16 at 12:39
Oh, yea, forgot about that one. Hard to tell if that is the problem from where I am. Not sure how to test that. I followed the same thing, so it should be the right way. – Flummox - don't be evil SE Nov 08 '16 at 12:50
For some reason, I didn't go through this http://android-developers.blogspot.com/2016/03/registering-oauth-clients-for-google.html. Is this the reason? – AIS Nov 08 '16 at 16:09
Yea, you need that. – Flummox - don't be evil SE Nov 08 '16 at 16:25
And? Don't leave us hanging ;) – Flummox - don't be evil SE Nov 08 '16 at 17:10
When the tutorial says "Create a web client ID for your server", the id is there, and I have included that in my Project, but what do we mean by 'your server'? Is the link provided by Google? Sorry a little lost here – AIS Nov 12 '16 at 07:59
I previously created a key for Google Maps, now do I create a separate key for Google Sign in? – AIS Nov 13 '16 at 07:43
Yes, they are separate. – Flummox - don't be evil SE Nov 13 '16 at 12:04
See my Manifest file...this way? – AIS Nov 13 '16 at 13:08

Try below code

           private void handleSignInResult(GoogleSignInResult result) {
                Log.d(String.valueOf(LoginActivity.this), "handleSignInResult:" + result.isSuccess());
                if (result.isSuccess()) {
                    // Signed in successfully, show authenticated UI.
                    GoogleSignInAccount acct = result.getSignInAccount();
              if (acct != null) {

                        Intent iWelcomeActivity = new Intent(MainActivity.this, WelcomeActivity.class);
                        iWelcomeActivity.putExtra("USERNAME", acct.getDisplayName());
                        iWelcomeActivity.putExtra("EMAIL", acct.getEmail();
);
                        startActivity(iWelcomeActivity);
                    }
                } else {
                    // Signed out, show unauthenticated UI.
                    //updateUI(false);
                }
            }

When user taps sigin button an intent will prompts the user to select a Google account to sign in with. onActivityResult method, retrieve the sign-in result and handleSignInResult(GoogleSignInResult result) is called .

If sign-in succeeded, you can call the getSignInAccount method to get a GoogleSignInAccount object that contains information about the signed-in user. Use GoogleSignInAccount object to retrieve information as acct.getDisplayName(),acct.getEmail() and pass it to next activity as done in above code.

Hopes it will help

Tried your code, 11-06 19:36:33.118 468-468/com.example......LoginActivity@5956e2d: handleSignInResult:false – AIS Nov 06 '16 at 14:38
When debugging, in OnActivityResult, GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data); result has nothing – AIS Nov 06 '16 at 14:41
is data in OnActivityResult null?? – Rissmon Suresh Nov 06 '16 at 14:46
Yes, nothing in data. Do you want me to post all the contents in data?As – AIS Nov 06 '16 at 14:57
data = {Intent@5130} "Intent { (has extras) }" mAction = null mCategories = null mClipData = null mComponent = null mContentUserHint = -2 mData = null mExtras = {Bundle@5177} "Bundle[{googleSignInStatus=Status{statusCode=DEVELOPER_ERROR, resolution=null}}]" mFlags = 0 mPackage = null mSelector = null mSourceBounds = null mType = null shadow$_klass_ = {Class@1392} "class android.content.Intent" shadow$_monitor_ = -2000768399 – AIS Nov 06 '16 at 15:02
When I uninstall the app, and start again, it shows dialog with gmail accounts but does not start ActivityUserProfile. From then on, even the dialog doesnt open on clicking – AIS Nov 06 '16 at 15:04

I was getting this same error, until I found this SO question. The problem was that if you don't configure your debug build to use your release signing key, it will use a default debugkeystore instead. If you've set up the API Key correctly, they won't match. Obviously, it would work if you build a release .apk with your release signing key, but if you are debugging (in development) you may have overlooked this process.

The Solution

Goto Build > Edit Build Types...
On the Signing Tab, Create a new entry for your release signing key alias and keystore. You can name it whatever you like, I used 'release'.
Now, on the Build Types Tab, for the 'debug' build type, Set the Signing Config to whatever was created in step 2.
Click OK, and Run the app again.
