Can't perform IO in Unity Android build

So there is this game where I am using File I/O to store game data like high score and all that. It works fine in windows pc build(.exe) but I cant load the high score on android app.

I am just using a simple file name that gets created(if not exist) in the executable directory but same code doesn't seems to be working with android.

string dataFile = Constants.GameDataFilePath; gameDataFile = File.Open(dataFile, FileMode.OpenOrCreate, FileAccess.Read, FileShare.None);
