Logout/Disconenct from Google Plus (Ionic/Cordova - cordova-plugin-googleplus)

Question

I am trying to Logout/Disconnect from Google Plus (I'm using cordova-plugin-googleplus https://github.com/EddyVerbruggen/cordova-plugin-googleplus/)

Here is what is happening: I login to Google Plus through my application successfully and a logout button shows up. If i click logout, it will logout correctly and everything works great! however If i open my application, login to Google Plus successfully and close the application completely, when i open the app again and try to logout it gives me an error: Please use login or trySilentLogin before disconnecting

coming from this code inside GooglePlus.java from the plugin:

    private void disconnect() {
    if (this.mGoogleApiClient == null) {
        savedCallbackContext.error("Please use login or trySilentLogin before disconnecting");
        return;
    }

    ConnectionResult apiConnect = mGoogleApiClient.blockingConnect();

    if (apiConnect.isSuccess()) {
        Auth.GoogleSignInApi.revokeAccess(this.mGoogleApiClient).setResultCallback(
                new ResultCallback<Status>() {
                    @Override
                    public void onResult(Status status) {
                        if (status.isSuccess()) {
                            savedCallbackContext.success("Disconnected user");
                        } else {
                            savedCallbackContext.error(status.getStatusCode());
                        }
                    }
                }
        );
    }
}

And here is my code home.ts :

Logout() {
    let env = this;
    this.googlePlus.disconnect().then(
        (msg) => {
              if(firebase.auth().currentUser){
                firebase.auth().signOut();
              }
              env.nativeStorage.remove('user');
        }).catch(
        (msg) => {
            alert('logout error: '+msg);
        })
    ;
  }

The code that keeps me signed in as it seems without the application being aware that its "signed in" is in the home.ts constructor:

this.user = this.afAuth.authState.switchMap(user => {
 if (user) 
 {
    return this.afs.doc<User>(`users/${user.uid}`).valueChanges()
 } else 
 {
    return Observable.of(null)
 }
 })

user is of type Observable:

   user: Observable<User>;

Even after closing the application and reopening it I can still see the changes being made to the database even though i can't logout!

I hope that clarified my problem.

Thank you

Got it! Using trySilentLogin. You will have to Implement it exactly like the implementation of login() and it will work beautifully!

Also don't forget to add it to the constructor:

this.yourfunctioname();

and inside you wll have he googlePlus.trySilentLogin() code!
