I have an Android app that deals with GPS data. When a user starts it, it offers to turn on the GPS.
Is it smart (or is it bad) if I code the app to automatically turn off the GPS when a user closes the app?
What about automatically turning off Wi-Fi or Bluetooth?
Since about Android 1.6, it has not been possible to turn GPS off/on programatically. All you can do is launch the system preference screen, which does allow the user to disable/enable it for all applications.
