I am looking for a simple application for Android - that would allow my users to save (and change) their email address and would upload their GPS coordinates to my server after 5 mins, for example.
The app would be downloaded:
1. User inputs email address and password and clicks save.
2. App initiates; syncs with GPS chip.
3. Uploads to my server every 5 min (if location has changed).
4. Spawns my website in the browser.
5. User can change email address and minimize app.
