THanks Charlie, and thanks to Mark, now I've a new problem, I'm very
sorry but I'm a "beginners" of Android , I'm not able to read a file!!
First of all I've found the file in the File explorer, but I can see
only the icon and can't open it ,it seems also tha the file Data.dat
is empty, as a matter of fact the size showed in the File Exolorer is
"0" .
Second ,what is the right way to read file from an Android
application?
like this: ??
/******************************************/
Scanner s=new Scanner("Data.dat");
while (true) {
String l = s.nextLine(); }
/*****************************************/
Thanks a lot:)
