Unless you are moving quite rapidly or you need very, very precise locations, you can grab the location coordinates once for a series of photos, starting before they snap the first shot. There shouldn't be a need to reach out to the GPS separately for each and every photo. You might be able to use a background thread to poll for GPS coordinates every so often if the device is moving.
Consider that the most frequent use case for photos is a series at one location. You also might be able to interleave capture and display of the image with a delayed, background retrieval of GPS data to avoid the manifestation of a wait. lbendlin, how much is the time cost to get GPS data, and why would the GPS be just starting up when the user is taking pictures. I've taken geo-located pictures a number of times with my Android phone and I've never noticed any GPS delay in human scale. Are we talking microseconds, milli-, tens of, ...? Unless the delay approaches one second or higher, I don't anticipate users even noticing, much less becoming impatient. lbendlin wrote: > > Sure, write your own Camera app and put the data into the image EXIF.

That's a lot of question marks! -- Lew -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
