I am trying to integrate google play game services c++ sdk to my cocos2d-x game, but I failed.
So, I try to run sample NativeGame, but it failed too. (app crashes with same exception)

My test environment:

• Xcode 6.4
• iOS simulator - iphone6 (ios v8.4)
• Google+ iOS sdk v1.7.1
• Google Play Game Services C++ sdk v1.4.1

I am following steps in this get started guide https://developers.google.com/games/services/cpp/gettingStartedIOS

• Open NativeGame.xcodeproj
• Drag and drop google+ ios sdk and play game service c++ sdk to project's Frameworks folder.
• Create game in google play developer console. This get my oauth2 client id and bundle id.
• Setup bundle id in project. This id match the id setup in google play developer console.
• And edit the code, ViewController.mm, to modify variables GPG_CLIENTID, GPG_ACHIEVEMENTID, and GPG_LEADERBOARDID to real value.

When I run NativeGame, click the on screen 'Sign in', app crashes with the following message.

What's wrong with my steps?
I am not yet to be asked using which google test account to sign in, no consent screen displayed, and there is no google+ app in the simulator. Does this matter? I do not have real ios device to verify currently.

The GooglePlayGames podspec indicates that it relies on the GooglePlusOpenSource library version 1.7.1 or later.

This library contains old code from the "google-api-objectivec-client" that causes issues when submitting an app to Apple's App store. It is flagged as using private APIs.

A fix was pushed out to the "google-api-objectivec-client" 14 days ago in response to the issue posted 21 days ago in the following link.

google/google-api-objectivec-client#203

It appears that this fix has not made its way into the GooglePlusOpenSource library, and so any app submitted with the GooglePlayGamesServices will get rejected. Mine was just rejected for this exact reason.

When can I expect to have this issue resolved? Until it is, I can not submit my game to the AppStore.

If allow_automatch is set to false, I can still invite "Auto-Pick" players for my game. This same setting is working as should(with the same code) in Android, but not in iOS. I don't want players to have an option to invite random players.

I'm using Play Games C++ SDK Version 1.4.1.

Example of code I'm using to open invite UI:

gpgService_->RealTimeMultiplayer().ShowPlayerSelectUI(
            minCountPlayers_,
            maxCountPlayers_,
            false,
            [this, variant](gpg::RealTimeMultiplayerManager::PlayerSelectUIResponse const &response) {
                if (gpg::IsSuccess(response.status)) {
                    // Create room
                    gpg::RealTimeRoomConfig config = gpg::RealTimeRoomConfig::Builder()
                        .PopulateFromPlayerSelectUIResponse(response)
                        .SetVariant(variant)
                        .Create();
                    auto result = gpgService_->RealTimeMultiplayer().CreateRealTimeRoomBlocking(config, this);

                    if (gpg::IsSuccess(result.status)) {
                        realtimeRoom_ = result.room;
                        GpgOnShowWaitingRoom();
                    }
                    else {
                        GpgOnFailedShowWaitingRoom(result);
                    }
                }
                else {
                        SetFailedRace();
                }
            }
        );

Hi,
I'm trying to use ShowPlayerSelectUI() to display player selection list for a real-time multiplayer match, but it displays no friend, despite I have a lot of accounts in my circles.
What I did wrong? The app still in testing phase. I did add 2 accounts to tester list but they are not shown up on the selection list.

Thanks,

Hi,

I'm writing a multiplayer game which uses gpg RealtimeMultiplayer API.
I'm facing multiple issues with it:

1/ Reliable messages are not arriving in order

2/ I often get an error during the send, but the message still arrives

1/ Here is the log of what I'm sending (burst send)
cocos2d: sending chunk of size 4 to p_CPDEjqzHuPOlYRAB
cocos2d: sending chunk of size 1400 to p_CPDEjqzHuPOlYRAB
cocos2d: sending chunk of size 1400 to p_CPDEjqzHuPOlYRAB
cocos2d: sending chunk of size 1400 to p_CPDEjqzHuPOlYRAB
cocos2d: sending chunk of size 1400 to p_CPDEjqzHuPOlYRAB
cocos2d: sending chunk of size 1400 to p_CPDEjqzHuPOlYRAB
cocos2d: sending chunk of size 826 to p_CPDEjqzHuPOlYRAB
cocos2d: sending chunk of size 4 to p_CPDEjqzHuPOlYRAB
cocos2d: sending chunk of size 5 to p_CPDEjqzHuPOlYRAB
The message is printed right before calling RealTimeMultiplayer().SendReliableMessage().

And here is the log on the receiver side:
cocos2d: OnDataReceived from p_CNnB1Na874r21gEQAQ (Reliable): 4 bytes
cocos2d: OnDataReceived from p_CNnB1Na874r21gEQAQ (Reliable): 1400 bytes
cocos2d: OnDataReceived from p_CNnB1Na874r21gEQAQ (Reliable): 1400 bytes
cocos2d: OnDataReceived from p_CNnB1Na874r21gEQAQ (Reliable): 1400 bytes
cocos2d: OnDataReceived from p_CNnB1Na874r21gEQAQ (Reliable): 1400 bytes
cocos2d: OnDataReceived from p_CNnB1Na874r21gEQAQ (Reliable): 1400 bytes
cocos2d: OnDataReceived from p_CNnB1Na874r21gEQAQ (Reliable): 4 bytes
cocos2d: OnDataReceived from p_CNnB1Na874r21gEQAQ (Reliable): 826 bytes
cocos2d: OnDataReceived from p_CNnB1Na874r21gEQAQ (Reliable): 5 bytes
The message is printed at the begining of the OnDataReceived() method.

How is that possible, the documentation specifies that the Reliable data are sent and received in order (should be if it's using TCP). Is there a bug in the gpg sdk which calls the callback not in order (another thread might be receiving the data, and not calling the callback correctly?).
Another question, who is responsible for flow control? Is it the SendReliableMessage() API that bufferize my data if it cannot immediatly send it, or should I do it myself (if so, how do I know if the receiver if "full"?)

2/ I check the RealTimeMultiplayer().SendReliableMessage() status from the lambda passed to the function, and in my previous example, I got in the log for the very first chunk I sent:
cocos2d: Message sending status: FAIL (-3)
-3 being ERROR_NOT_AUTHORIZED
But the chunk arrived to the receiver.

Why did I get this error (only for the first message, but I sometimes have this error multiple time in a row)? Should I ignore send errors (not very safe, I want my game to stop if a player is not receiving the data)?

I did all my tests using an iPhone6 and an iPad4, using the same build.
I didn't even try using an iOS device with an Android one... yet.
Every run, I have some messages out of order and/or send errors. In fact on my 50+ runs, I never got the full message in order on the receiver.

Thanks!

Using Xamarin to implement Google Play Games Services for iOS I found that Play Games is not compatible with Sign-In v4.0.1 anymore because GoogleOpenSource framework (dependency of PlayGames) have duplicated symbols with GTMOAuth2 headers (dependency of Sign-In). Here's a list of duplicated symbols between libs:

'_kGTMOAuth2WebViewKey'.
error: Duplicate symbol in: GoogleOpenSource(GTMOAuth2Authentication.o) 
error: Duplicate symbol in: GTMOAuth2(GTMOAuth2Authentication.o)

Also, Play Games dependencies needs to be updated to replace GoogleOpenSource dependency with the new GTMOAuth2 and GoogleToolboxForMac/Logger open source projects.

Hi,

Using sdk 1.3 or 1.4, if I open the achievements UI (the default one), I'm not seeing the XP associated with the achievements (I have a "0 XP" string instead).
The same code on android works fine and I see the correct XP value.

This is from an alpha version of the game (PlayGames store listing is still in draft mode).
But since it works fine on android, maybe it's not related to being unpublished.

Attached in a screenshot of the iOS version showing 5 unlocked achievements, and 1 locked.
Both the unlocked and the locked show 0 XP.
On android they all correctly show the amount of XP I've set in my listing on google play console (sorry I don't have an android sshot available).

(Don't worry about the grey rectangles, I've obfuscated the text)

Got the same "bug" from the toasts on iOS (if it helps), showing 0 XP earned.

Thanks

Following your guide about the signing in within the google play games services sdk (using the GPGManager signing silently), the application works correctly on the simulator, while on the real device it appears like after having logged into (by the safari view), the GIDSignIn tries to present a new safari view by the call from the [GIDRuntimeConfigFetcher fetchWithURLString:history:].
This ends into a blank view blocking the app.
The failure happens every time on the real device.

Following is the stack having set a breakpoint in the signin:presentviewcontroller:
