Question

So, I was trying to get the solution of this problem. But, somehow I am unable to do so, May be because of the lack of knowledge in angular 5. This is my service:

Answer 1

Asynchronous functions cannot be called synchronously, because they are asynchronous.

subscribe generally shouldn't performed in methods that are expected to be chained. Even if it should, an observable and not a subscription should be returned from a method (a subscription can be additionally saved to be unsubscribed on destruction).

GetCurrentUserInformation method is redundant because it is just a wrapper for service call. The code can be refactored to:

ngAfterViewInit() {
    this.loginService.GetCurrentUserData().subscribe(data => {
        this.responseData = data;
        if (this.responseData.code != responseCodes.success) {
            this.googleInit();
        }
    });
}
