Update GPS Listener every 5 seconds

Question

I\'m supposed to update the listener every 5 seconds. But it doesn\'t. What could be wrong with my code?

Thanks a lot for any help!

package com.example.a         


        

Answer 1

By setting it to 5000 ms it doesn't necessarily mean that you will get the location every 5th second. The time is more or less a best case scenario.

minTime the minimum time interval for notifications, in milliseconds. This field is only used as a hint to conserve power, and actual time between location updates may be greater or lesser than this value. http://developer.android.com/reference/android/location/LocationManager.html

Are you sure you have your activity running? If you want to recieve the location when the activity is sleeping you need a wake lock and a service.

For example in a GPS app I created I put 0 ms to get it as soon as possible but when debugging and checking the logcat I sometimes get the location every minute or so, not every second.

Answer 2

As stated by David Olsson, MINIMUM_TIME_BETWEEN_UPDATES only prevents the listener to be requested too often. If you want to regularly requestLocationUpdates, you should use Timer and TimerTask and have requestLocationUpdates run once every 5 seconds

schedule(TimerTask task, long delay, long period)
Schedules the specified task for repeated fixed-delay execution, beginning after the specified delay.
