问题 in out app we have a module where you can send time records with GPS location. In 40% of cases we have location problem because the module provides a location which is not real (sometime about 1 km away). When we have this cases we open Google Maps app and it give us perfect location, then again out app and not-real location. For getting the location we use this: Slider s1 = new Slider(); Dialog dlg = makeDialog("HIGH PRECISION LOCATION...", s1, null, 'a'); dlg.addShowListener((ActionListener

问题 I have an application where I set current location (using Google Maps). Every time I open Google Maps inside the application in Android Studio emulator, it sets location to Mountain View (latitude = 37.4220186, longitude = -122.0839727). The emulator is Nexus 5 having Android SDK 30. If I change the location in settings to Moscow , the emulator can relocate to Moscow after clicking My location button, but sometimes it doesn't relocate. Then, after clicking the second time it can transfer to

问题 Using GPS points I am calculating by holding previous and current points with location1.distanceTo(location2) by adding each time to a variable on some time diff to get traveled distance. Is it good approach to get vehicle movement distance? Is any better approach to get accurate travel distance during moving vehicle? 回答1: Use the following code. I hope it will help. public double CalculationByDistance(LatLng StartP, LatLng EndP) { int Radius = 6371;// radius of earth in Km double lat1 =
