Question

I would like to use GPS in my application but in some specific way. I want to use it only when the user does something with the app, but when the app goes to sleep then the GPS should stop doing things. I wonder how to manage this in way in which I wouldn’t have to manage gps in all activities but only in one class or something similar.

Answer 1

If the GPS is used only in one Activity
Turn off the GPS when the Activity’s onPause() method is called.

@Override
protected void onPause()
{
//turn of GPS code here
super.onPause();
}

If your GPS is running in service you will have to have the service know if your app is running or not, what you can do is make a static boolean in the Service and every time any Activity’s onResume() method is called, set the Service’s boolean to true. Every time an Activity pauses, set the boolean to false.
