Unity I/O with Android device

Question

i can read and write file with this method for storing game progres.

filePath = Application.dataPath + "/";
filenam= "SavedGame";
extension = ".txt";

Lettura ----------------
var FRead = new File.OpenText(filePath + fileNam + extension);

for (var i : int= 0; i<N; i++) {

FRead.ReadLine();

}
Scrittura--------------------
var FWrite: StreamWriter = new StreamWriter(filePath + filenam + extension);
FWrite.WriteLine("AAAA");

A run time in the Unity editor all work perfectly.

But in Android device Application.dataPath seems dont work.

I tryed Application.persistentDataPath that work fine but in (Read Only),but i need place the SavedGame.txt manually in the patch.

I tried a fantomatic "jar:file://" + Application.dataPath + "!/assets/"; but dont work.

Note when i build the project in apk packege semms dont appear my SavedGame.txt,that in the editor is in UnityProject\\Assets .

Come posso risalire al percorso giusto del mio SavedGame.txt, posizionato in ad esempio in UnityProject\\Assets nei device?

How i cand do this in a correct way read and write SavedGame.txt in android device?

Answer 1

On android you might not have direct write access to the dataPath of the project.

Try using Application.persistentDataPath instead. This is where save files are intended to be stored.

Change:

filePath = Application.dataPath + "/";

to

filePath = Application.persistentDataPath + "\\";
