问题 I am getting current Lats and Longs using FusedLocationProviderClient and I am using the below code to get current lats and longs of the device: public class FusedGpsService extends Service { private FusedLocationProviderClient fusedLocationProviderClient; private double speed; Data datas; List<Location> locationList; @Override public void onCreate() { super.onCreate(); fusedLocationProviderClient= LocationServices.getFusedLocationProviderClient(this); requestLocations(); Log.i("STATR",

问题 I am working on the GPS part of a project and I would like to get something past the community. I have searched around for all the typical GPS "jumping and drifting" and I have worked on improving what I get but last week I got some really weird data that I cannot put my finger on. The application basically has a foreground service that tracks the location and then uploads that data on a timer. Of course we have all the proper permissions needed and there is also a filter that weeds out data

问题 I am trying to write an app that tracks location in background and sends data to a server -- to monitor where my family members are, for example. Currently I am playing with https://github.com/android/location-samples, particularly with LocationUpdatesBackgroundKotlin that seems to be the best way to receive location updates, but after receiving about 8-10 location updates in background, the gps icon on the status bar dies without anyway notifying the application (here is the android/phone

问题 Update 2 I had a talk with a google engineer on Google I/O '18. He told me that I can trust the fusedLocationProvider. If he marks the last known location with a new timestamp the user is probably still at the same location. I'd like to do a few tests with a "moving" device in the future to prove this statement. Original Question I'm requesting the last known location from the FusedLocationProviderClient with getLastLocation() and want to check if the last known location is older than 5
