Here are the errors.
I am creating a firebase login and sign up unity project.
I have commented some of the lines because I havent programmed it yet. I am following this tutorial : https://www.youtube.com/watch?v=9-ZS7-I_CfQ
I have 2 scripts, firebaseManager and authUI manager.
Here is my firebaseManager script:

In your FirebaseManager script you've put a semicolon ; at the end of line 264 instead of a comma ,.
Additionally you've put a desperate closed curly bracket } at the end of the file, which is not necessary.
All other errors basically originate from these two problems.

PlayerStats.Valid not return true

I'm trying to get user status through google play services to make a daily rewards system for my game and I'm not getting the value back as true, my game connects to google play but I can not get the user's data. Here is the code snippet below
private string gameId = "3140248";
private bool testMode = true;
public List<Upgrades> upgrades = new List<Upgrades>();
public List<Area> areas = new List<Area>();
public Text Loading;

PlayerStats = new PlayerStats();

Unity "SceneManager.activeSceneChanged" getting called when "LoadSceneAsync" and load other scene

first, there is a singleton object simply is subscribed to activeSceneChanged
SomeSingleton.cs
void Awake ()
{
Debug.LogError ("AWAKE");
if (instance == null) {
Debug.LogError ("instance == null");
instance = this;
MusicController.instance = this;

} else {

}
}
void OnSceneChanged (Scene previousScene, Scene changedScene)
{
Debug.LogError ("OnSceneChanged changedScene = " + changedScene.name);
}
from Lobby Scene player moves to Room Scene.
in room scene.
the "Arena" Scene gets preloaded for better game experience.
LoadSceneAsync("Arena")
with allowSceneActivation = false
when player clicks play button, sets allowSceneActivation = true
but when user decides to go back and clicks Leave Button, LoadScene("Lobby") gets called.
At this time in console, it will Log
LOGS
OnSceneChanged changedScene = Lobby // time : 0.793
OnSceneChanged changedScene = Room // time : 3.982
[when player clicks Leave Button]
OnSceneChanged changedScene = Arena // time : 7.583
OnSceneChanged changedScene = Lobby // time : 7.583
like this...
it just gets activated but wont actually load the scene. why is Arena getting activatd? how to solve this problem???
should i do some unload thing to the AsyncLoading?

Xamarin IOS: unable to play mp3 from internet

I read a lot of documentation regarding this problem, but I don't seen any answer.
I have a Xamarin form app that play mp3 sample music from the Groove music service.
On Android, everyhting workd fine.
On Ios, I'm not able to play the sound. I get the URL and it's not possible to ear anything (I was able to play a local mp3)
I see this problem occured also for people using SWIFT : How to play MP3 From URL in iOS
I also found several exemple on the Xamarin forum but no sound neither: https://forums.xamarin.com/discussion/19883/how-do-i-get-the-avplayer-to-play-an-mp3-from-a-remote-url
Here is the code I use:
public class AudioService : IAudio
{
protected string FileName = string.Empty;
protected AVPlayer Player;
public bool IsPlaying { get; private set; }
public void Init(string fileName)
{
//FileName = fileName;
string second = "http://progdownload.zune.net/145/119/034/170/audio.mp3?rid=0b80911a-ba3b-42ec-b17f-c242ba087024-s4-nl-BE-music-asset-location";
FileName = second;
QueueFile();
}
public async void PlayStream(string uri)
{

System.Diagnostics.Debug.WriteLine("Enter in function");
Player.Play();
System.Diagnostics.Debug.WriteLine("Play sound");
System.Diagnostics.Debug.WriteLine(FileName);

}
using (var url = NSUrl.FromString(FileName))
{
var test = AVAsset.FromUrl(url);
var playerItem = AVPlayerItem.FromAsset(test);
// if Player is null, we're creating a new instance and seeking to the spot required
// otherwise we simply resume from where we left off.
if (Player == null)
{
Player = AVPlayer.FromPlayerItem(playerItem);
if (Player == null)
{
// todo: what should we do if the file doesn't exist?
return;
}
}
}
}}
(IAudio just implements playstream and stop)
If you click on the url, your browser will be able to play music

Does any one was able to play mp3 from internet

The answer in the info.list file. You need to add this to your info.list:
<key>NSAppTransportSecurity</key><dict>
<key>NSAllowsArbitraryLoads</key>
<true/></dict>
I had the same issue and resolved it.

I've made some cleaning for your code :)

Chartboost ads not showing in Unity 3D Game

I have a simple platformer game in which I'm using chartboost and unity ads t show ads and I it was working fine during the test mode but ever since I deployed to production and disabled the test mode in both chartboost and unity ads I noticed that my interstitial ads and videos don't load or show except once in a blue moon that too of a same game and then it start failing again.
I also noticed that my ads impression are quite low on the chartboost and Unity. Can you please tell me if I code for it correctly? I used the chartboost example an built my ad controller through it, oh and I'm using caching for ads and unless ad isn't cached already I won't show it.

Run cache after every time you show an interstitial.
like this :
Chartboost.showInterstitial(CBLocation.Default);
Chartboost.cacheInterstitial(CBLocation.Default);
That way you will replenish the cache every time you show an ad.
Remember to cache as soon as its initialized as well.
