Error: Status{statusCode=DEVELOPER_ERROR, resolution=null}

I am usign gplus sign in, and getting this error at time I am in onActivityResult....

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    callbackManager.onActivityResult(requestCode, resultCode, data);
    client.onActivityResult(requestCode, resultCode, data);

    if (requestCode == 0) {
        GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
        if (result.isSuccess()) {

            GoogleSignInAccount acct = result.getSignInAccount();
//                Log.d("Result","details"+ acct.getDisplayName() + acct.getEmail());

            mEmail = acct.getEmail();
            String mFullName = acct.getDisplayName();
            String mGoogleplusId = acct.getId();


            SocialUser user = new SocialUser();
            user.setType("googleplus");

            user.setEmail(mEmail);
            user.setFullname(mFullName);
            user.setId(mGoogleplusId + "");
            loginParams.put("email_id", mEmail);
            loginParams.put("googlePlusId", mGoogleplusId);
            loginParams.put("full_name", mFullName);
            loginParams.put("registrationType", "googleplus");
            SignUpService(user);


        } else {
            Toast.makeText(CustomerLogIn.this, "Unable to fetch data, Proceed manually", Toast.LENGTH_SHORT).show();
        }
    }
}

And I am calling for gplus login on button click. On clcking button following code is executed....

 GoogleSignInOptions googleSignInOptions = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestEmail()
            .build();
    mGoogleApiClient = new GoogleApiClient.Builder(CustomerLogIn.this)

            .addApi(Auth.GOOGLE_SIGN_IN_API, googleSignInOptions)
            .build();


    Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
    startActivityForResult(signInIntent, 0);

And I am geetng this error...

Status{statusCode=DEVELOPER_ERROR, resolution=null}

on this line....

GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);

Please suggest the solution.

You need to add your SHA1 key to firebase console configuration. You can do it in this way:

Firebase console ( https://console.firebase.google.com ) -> your project -> configuration -> scroll to

You can find your SHA1 key running "Signing report" from Android Studio:

Then, look the "run tab" and click the button:

I think it's the easier way. Hope this help.
