Hi,

I’m facing some problems recently with Android Build. I have a class to handle save locally, iCloud and Google Snapshot. It works like this:

public class DataCloudPrefs
{
        public static void SetInt(string key, int value)
    	{
    		#if CLOUDDATA_IMPLEMENTED
    
    			#if UNITY_IOS
    			iCloudBinding.setInt( value, key );
    			#elif UNITY_ANDROID
    			snapshotKeys.Add(key, value);
    			#endif
    
    		#endif
    
    		PlayerPrefs.SetInt(key, value);
    		PlayerPrefs.Save();
    	}

    public static int GetInt(string key)
	{
		#if CLOUDDATA_IMPLEMENTED

			#if UNITY_IOS
			return P31Prefs.getInt(key);
			#elif UNITY_ANDROID
			return int.Parse(snapshotKeys[key].ToString());
			#endif

		#endif

		return PlayerPrefs.GetInt(key);
	}
 }

So, I implemented a rewarded video on my game. On OnComplete function I call, for example:

GameController.Coins += 100;

which goes something like this:

public class GameController : MonoBehaviour
{
   private static int coins = 0;

   public static int Coins
   {
      get { return SaveController.Coins; }
      set 
      { 
           coins = value;
           SaveController.Coins = coins; 
      }
   }
}

public class SaveController : MonoBehaviour
    {
       public static int Coins
       {
          get { return DataCloudPrefs.GetInt("COINS"); }
          set { DataCloudPrefs.SetInt("COINS", value); }
       }
    }

This runs normally on Unity, on iOS, but on Android it returns me this error:

Why is this?
