Re: [android-developers] improving gps lock time

If the GPS has been on and the user turns off the screen, there's
nothing you can do to really get a better approximation to location.

Let's be realistic here: how accurate does your signal need to be? If
it's pinpoint accuracy (within 60-200 m) then you should be getting
constant fixes anyway. If it's not, then why is fixing the results of
the output so bad? If you want a good trade off, I'd say to set up an
alarm manager that requests location fixes at a coarse interval.
