Hey I am trying to use Unity Cloud Save feature.
I’ve added SDK for Cloud Save and Authentication and Linked Unity Project. I am also using Firebase so there is also configuration for it.
All fun starts here in the Start() method of some initial script let’s say GameManager
private void Start()
{
Debug.Log("CloudSave: StartSceneLoader Start");
FirebaseApp.CheckAndFixDependenciesAsync().ContinueWithOnMainThread(task => {
var dependencyStatus = task.Result;
if (dependencyStatus == DependencyStatus.Available)
{
InitializeFirebase();
AuthManager.Instance.SignIn(() => {
StartCoroutine(WaitAndLoadGame());
});
}
else
{
Debug.LogError($"Could not resolve all Firebase dependencies: {dependencyStatus}");
}
});
}
I did basic Firebase initialization (there is no InitializeFirebase() method here but it is irrelevant). Then after this initialization I’ve run my SignIn() method on AuthManager singleton and there is a callback which launch problematic WaitAndLoadGame(). I’ve added listings with SignIn method but I don’t think it is necessary beacause the fact that this is the part which seems to work well. I can see the login Google Play Games animation and I can see all those logs which ensures me that I am logged.
public async void SignIn(Action callback)
{
await UnityServices.InitializeAsync();
PlayGamesPlatform.Activate();
SignInWithGooglePlayGames(callback);
}
private void SignInWithGooglePlayGames(Action callback)
{
PlayGamesPlatform.Instance.Authenticate(success =>
{
if (success == SignInStatus.Success)
{
Debug.Log("CloudSave: Login with Google Play games successful.");
PlayGamesPlatform.Instance.RequestServerSideAccess(true, code =>
{
Debug.Log($"CloudSave: Authorization code: {code}");
SignInWithGooglePlayGamesAsync(code, callback);
});
}
else
{
Debug.Log("CloudSave: Login Unsuccessful: Failed to retrieve Google play games authorization code");
}
});
}
private async void SignInWithGooglePlayGamesAsync(string authCode, Action callback)
{
try
{
await AuthenticationService.Instance.SignInWithGooglePlayGamesAsync(authCode);
await CheckPlayerInfoAndLinkAsyncAndroid(authCode);
FirebaseAnalytics.SetUserId(AuthenticationService.Instance.PlayerId);
Analytics.SendPlayerLoginEvent();
callback?.Invoke();
Debug.Log($"CloudSave: SignIn is successful. PlayerID: {AuthenticationService.Instance.PlayerId}");
}
catch (AuthenticationException ex)
{
HandleAuthException(ex);
}
catch (RequestFailedException ex)
{
HandleRequestFailedException(ex);
}
}
Let’s back to the problematic part
AuthManager.Instance.SignIn(() => {
StartCoroutine(WaitAndLoadGame());
});
In WaitAndLoadGame() method I am trying to load the data from the cloud so await GameSaver.Load().Result;
private IEnumerator WaitAndLoadGame()
{
Debug.Log("CloudSave: Loading game data...");
var gameData = await GameSaver.Load().Result;
Debug.Log("CloudSave: Data loaded...");
...
}
And then in GameSaver.Load() I’ve just await LoadFileStream() and deseralize it to GameData
public static async Task<GameData> Load(){
await using var fileStream = await LoadFileStream(SAVE_GAME_FILE_NAME);
var savedData = formatter.Deserialize(fileStream) as GameData;
return savedData;
}
And this is the LoadFileStream(string key) listing:
protected static async Task<Stream> LoadFileStream(string key)
{
try
{
Debug.Log($"CloudSave: Attempting to load data from cloud: [{key}]");
await using var cloudStream = await CloudSaveService.Instance.Files.Player.LoadStreamAsync(key);
return cloudStream;
}
catch (CloudSaveValidationException e)
{
foreach (var detail in e.Details)
{
Debug.LogError(detail.Field);
foreach (var msg in detail.Messages)
{
Debug.LogError(msg);
}
Debug.LogError(detail.Key);
}
return null;
}
catch (CloudSaveRateLimitedException e)
{
Debug.LogError(e);
Debug.LogError(e.RetryAfter);
return null;
}
catch (CloudSaveException e)
{
Debug.LogError(e);
Debug.LogError(e.Reason);
return null;
}
Debug.LogError("CloudSave: LoadFileStream, uncatched!");
return null;
}
Basically if we skip the catch sections there is this line:
await using var cloudStream = await CloudSaveService.Instance.Files.Player.LoadStreamAsync(key);
This is problematic. When I run the game on Android device I can see that it is signing in then it goes to this line and then is basically dead.
The log which is just one line above, that one:
Debug.Log($"CloudSave: Attempting to load data from cloud: [{key}]");
Is last log from the application. But application don’t crash, its activity is still on top and I can see it. But there are no more logs the code execution appears to be somehow stopped.
This is part of my logcat from this situation:
CloudSave: Attempting to load data from cloud... [w151664_w2h3y1_6.dat]

There is more gibberish but there is generally nothing to investigate, just system related things. There is this android.database.sqlite.SQLiteConstraintException exception right below the last log but don’t think it is related I can see many of those errors when looking at logcat.
During development I first have bad file name (key) and I had forbidden character there. In that case there was an CloudSaveValidationException and I could read about a naming problem from the logs.
Also if I disable login to Google Play Games there is an CloudSaveException that I am not logged.
But when the file name is right and I am logged in it just hangs.
Uff I hope you are still here, that’s it. No idea how to pass this issue.
