Question

i’m trying my first android app and it should track my route with gps coorinates.
The app also has a five textboxes, each with about 30 chars user can type in.
Coordinates should be saved all 30/60 seconds, is this enough?
Or is it possible to save it with 10 seconds and what’s the right way to save it?
Thought about reading xml from url, but I think it could be more data in future.
What could be a good way to store it on sd as XML or normal file locally, which I can parse from client-pc to retrieve coordinates?

Thanks for your time.
Best Regards

Answer 1

You should only save a position if it’s far enough away from the previous position. That way you’ll have way less data without losing any information (in other words – it doesn’t help to save the same position every 10 seconds).

In my sports tracker app, I save the data in a database table (latitude, longitude, timestamp … basically all you get in the Location object).
