write the gps coordinates to text file

[Deema]

Hello,
I hope you're all doing well ,,

I have already implemented j2me tracking application, that:
gets the GPS Coordinates every two minutes and and check whether the previous coordinates are equal to the new one, if so it will save it to text file with the current time. When it's going to write to the file, it must check whether it's new day or not, if so then it must write the date to the file before start writing the coordinates.

Sample Output file:

DATE

TIME
COORDINATE

TIME
COORDINATE

,and so on..

Now I'm facing some problems that prevent the application from working appropriately. Such as:
1- The application works as its should be at the first time,, but in the next time it couldn't get the coordinate,, it's display "unknown" in the mobile screen.

2- Each time when its going to write to the file,, it keep asking for the Security Permission,, is there is away to make the application trusted so the user wouldn't be consulted for all permissions.

I really appreciate it if u can help.

Advance Thanks,
Regards,
Deema.

for 1st --> try using LocationListener, to give you co-ordinates on every change in location - rather then asking every 2 min's this will be most optimized way to do it.

for 2nd --> you can go for signing the application using any 3rd party code signing tool, which will allow the end user to grant permission to the app to "ask only once" for write permission on some devices which you need to educate the end user for.
