How to setting firebase remote config for unity? - unity3d

Question

lets to the point, so i want to make some configuration with my game to show Ads but I avoid to update game version too much, because of that I choose firebase remote config with this I can update setting/configuration without update the game version.
there is document for this but not very clear for newbie like me, you can check it here https://firebase.google.com/docs/remote-config/use-config-unity
I already make the script like on doc, but I don't understand how its work on show data because error string format, which is what I know on this firebase console is int format
the script like this :
public static _FirebaseRemoteConfig instance;
private void Awake()
{
instance = this;
}
Firebase.DependencyStatus dependencyStatus = Firebase.DependencyStatus.UnavailableOther;
// Use this for initialization
void Start()
{
Firebase.FirebaseApp.CheckAndFixDependenciesAsync().ContinueWith(task =>
{
dependencyStatus = task.Result;
if (dependencyStatus == Firebase.DependencyStatus.Available)
{
InitializeFirebase();
}
else
{
Debug.LogError(
"Could not resolve all Firebase dependencies: " + dependencyStatus);
}
});
}
public void InitializeFirebase()
{
System.Collections.Generic.Dictionary<string, object> defaults =
new System.Collections.Generic.Dictionary<string, object>();
defaults.Add("config_test_string", "default local string");
defaults.Add("config_test_int", 1);
defaults.Add("config_test_float", 1.0);
defaults.Add("config_test_bool", false);
Firebase.RemoteConfig.FirebaseRemoteConfig.SetDefaults(defaults);
Debug.Log("Remote config ready!");
}
public void FetchFireBase()
{
FetchDataAsync();
}
public void ShowData()
{
Debug.Log("maxCountToShowAdmob: " +
Firebase.RemoteConfig.FirebaseRemoteConfig.GetValue("MaxCountShowIntersitialAds").LongValue);
}
// Start a fetch request.
public Task FetchDataAsync()
{
Debug.Log("Fetching data...");
System.Threading.Tasks.Task fetchTask = Firebase.RemoteConfig.FirebaseRemoteConfig.FetchAsync(
TimeSpan.Zero);
return fetchTask.ContinueWith(FetchComplete);
}
void FetchComplete(Task fetchTask)
{
if (fetchTask.IsCanceled)
{
Debug.Log("Fetch canceled.");
}
else if (fetchTask.IsFaulted)
{
Debug.Log("Fetch encountered an error.");
}
else if (fetchTask.IsCompleted)
{
Debug.Log("Fetch completed successfully!");
}
var info = Firebase.RemoteConfig.FirebaseRemoteConfig.Info;
switch (info.LastFetchStatus)
{
case Firebase.RemoteConfig.LastFetchStatus.Success:
Firebase.RemoteConfig.FirebaseRemoteConfig.ActivateFetched();
Debug.Log(String.Format("Remote data loaded and ready (last fetch time {0}).",
info.FetchTime));
break;
case Firebase.RemoteConfig.LastFetchStatus.Failure:
switch (info.LastFetchFailureReason)
{
case Firebase.RemoteConfig.FetchFailureReason.Error:
Debug.Log("Fetch failed for unknown reason");
break;
case Firebase.RemoteConfig.FetchFailureReason.Throttled:
Debug.Log("Fetch throttled until " + info.ThrottledEndTime);
break;
}
break;
case Firebase.RemoteConfig.LastFetchStatus.Pending:
Debug.Log("Latest Fetch call still pending.");
break;
}
}
