what want user location after every 30 seconds code not work expected. gets location fast (i think every second).

i tried location way because can current location after start app.i have tried getlastknowlocation before, give me last known location far am.

please show me how fix this.thank you!

in requestlocationupdates method second parameter minimum time interval between location updates, in milliseconds, need this:

locationmanager locationmanager = (locationmanager) getsystemservice(context.location_service); locationmanager.requestlocationupdates(locationmanager.gps_provider, 30 * 1000, 0, timedisplaytimertask.this);
