I've been tried to save something in Android using Unity Built in PlayerPrefs. It sometimes work and sometimes not. I tried to save Array object (boolean[]) with PlayerPrefsX, but it didn't work on Android. I also tried PreviewLabs PlayerPrefs, but it only works in C#. Does anyone have any idea to save array in Android ?

EDIT : It works well if save something with unity PlayerPrefs, what happen if i save 70 objects (boolean + float) in Android Unity playerPrefs ?
