Getting user credentials using Google+ API

1.4k views Asked by At

I am trying to include Google sign in in my android application using Google+ Api. I am able to take account details from the user but once signed in I am getting null when requesting for username using call:

Plus.PeopleApi.getCurrentPerson(mGoogleApiClient).getDisplayName()

And Logcat shows:

BasicNetwork.performRequest: Unexpected response code 403 for https://www.googleapis.com/plus/v1/people/me

Although I am able to get email of the user using:

Plus.AccountApi.getAccountName(GoogleClient.mGoogleApiClient)

Please help me to discover my mistake

I have tried same code and its working fine! So, just ensure two things:

1)Register your digitally signed .apk file's public certificate in the Google APIs Console.Link below:

https://developers.google.com/+/mobile/android/getting-started#step_1_enable_the_google_api

2)Make sure you have added the google+ api access and have client key created with SHA1.
Rest is fine.

I think basic steps of google+ login integration in app is known by you.Here are the rest of the steps

step 1-- in oncreate

 mGoogleApiClient = new GoogleApiClient.Builder(this)
         .addConnectionCallbacks(this)
         .addOnConnectionFailedListener(this)
         .addApi(Plus.API)
         .addScope(Plus.SCOPE_PLUS_LOGIN)
         .build();

step 2-- in login button click listener call this----

private void LoginGoogle(){
        int errorCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(context);
        if (errorCode != ConnectionResult.SUCCESS) {
          GooglePlayServicesUtil.getErrorDialog(errorCode, this, 0).show();
        }
        else{
            //perform login
            if (!mGoogleApiClient.isConnecting()) {
                mSignInClicked = true;
                mGoogleApiClient.connect();

            }
        }
    }

step 3---- in onActivityresult

if (requestCode == RC_SIGN_IN) { 
                if (resultCode != RESULT_OK) {
                  mSignInClicked = false;
            }

            mIntentInProgress = false;

            if (!mGoogleApiClient.isConnected()) {
              mGoogleApiClient.reconnect();
            }
          }

step 4-----

    @Override
    public void onConnectionFailed(ConnectionResult result) {
        // TODO Auto-generated method stub
        if(!mIntentInProgress){
            if ( mSignInClicked && result.hasResolution()) {
                 // The user has already clicked 'sign-in' so we attempt to resolve all
                  // errors until the user is signed in, or they cancel.
                  try {
                    result.startResolutionForResult(this, RC_SIGN_IN);
                    mIntentInProgress = true;
                  } catch (SendIntentException e) {
                    // The intent was canceled before it was sent.  Return to the default
                    // state and attempt to connect to get an updated ConnectionResult.
                    mIntentInProgress = false;
                    mGoogleApiClient.connect();
                  }

              }
        }
    }
    @Override
    public void onConnected(Bundle arg0) {
        // TODO Auto-generated method stub
        mSignInClicked = false;
        getProfileInformation();
    }
    @Override
    public void onConnectionSuspended(int arg0) {
        // TODO Auto-generated method stub
        mGoogleApiClient.connect();
    }


    @Override
    protected void onStop() {
        // TODO Auto-generated method stub
        super.onStop();
        if (mGoogleApiClient.isConnected()) {
              mGoogleApiClient.disconnect();
            }

    }

step 5-----

private void getProfileInformation(){
        try {
            if (Plus.PeopleApi.getCurrentPerson(mGoogleApiClient) != null) {
                Person currentPerson = Plus.PeopleApi.getCurrentPerson(mGoogleApiClient);
                String id=currentPerson.getId();
                String personName = currentPerson.getDisplayName();
                String personPhoto = currentPerson.getImage().getUrl();
                String email = Plus.AccountApi.getAccountName(mGoogleApiClient);

                String profilePic=personPhoto.substring(0,
                        personPhoto.length() - 2)
                        + ProfilePicSize;

                Log.e("GOOGLE", id);
                Log.e("GOOGLE", personName);
                Log.e("GOOGLE", profilePic);
                Log.e("GOOGLE",email);


              }

        } catch (Exception e) {
            e.printStackTrace();
        }
    }
