Can't use with Facebook SDK

[kremedved]

Can't use google-signin-unity with Facebook SDK. After Facebook sign in, browser shows blank(white) screen and nothing happens.

Steps to reproduce:

1. Create a new unity project, add facebook sdk from https://developers.facebook.com/docs/unity/downloads/ using version 7.10.1;
2. Implement sign in with facebook;
3. Add google-signin-unity to unity project;
4. Build xcode project for iOS;
5. Build app, open it, try to sign in with Facebook. After sign in, browser shows blank(white) screen and nothing happens.

If I delete /Assets/Plugins/iOS/GoogleSignIn/GoogleSignInAppController.* from my unity project, Facebook auth works correctly.

Tried with unity 5.5.2, 5.6.4;
play-services-resolver v1.2.59.0.

I can confirm this issue is happening as I've encountered the same problem. In Android, the Facebook login works but the Google signin button does not as I'm unable to resolve all dependencies as described in issue #5

I ran into the same issue earlier today and solved it by modifying the GoogleSignInAppController.mm file directly with the following changes:

1. Add near the top:

#import <FBSDKCoreKit/FBSDKApplicationDelegate.h>

2. Modify these two methods to call both Google + Facebook's URL handler callbacks:

/**
 * Handle the auth URL.
 */
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary *)options {
  return
      [[GIDSignIn sharedInstance] handleURL:url
                          sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]
                                 annotation:options[UIApplicationOpenURLOptionsAnnotationKey]] ||
      [[FBSDKApplicationDelegate sharedInstance] application:app
                          openURL:url
                sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]
                       annotation:options[UIApplicationOpenURLOptionsAnnotationKey]];
}

/**
 * Handle the auth URL
 */
- (BOOL)application:(UIApplication *)application
              openURL:(NSURL *)url
    sourceApplication:(NSString *)sourceApplication
           annotation:(id)annotation {
  return [[GIDSignIn sharedInstance] handleURL:url
                             sourceApplication:sourceApplication
                                    annotation:annotation] ||
         [[FBSDKApplicationDelegate sharedInstance] application:application
                          openURL:url
                sourceApplication:sourceApplication
                       annotation:annotation];
}

I've only tested this on iOS so far. I'll report back if I find any issues with the Android version.

It looks like this plugin could benefit from using Unity's UnityRegisterAppDelegateListener method instead of overriding UnityAppController, which is what the Facebook SDK does.

This is fixed in version 1.0.2 of the plugin.

Using Unity Package Version 1.0.2.
I am trying to use this package with facebook sdk but it gives me error:

Looks like the error was truncated - I see most of the command line, but not the actual error. Can you open a new Issue and maybe put the log in a Gist?
