But when I put the location listener in a timer task, it throws an exception: Cannot put code inside thread that has not called looper.prepare() . Does anyone have any insight on this problem? 回答1: You need not to start a service for recieving locationUpdate every 10 min instead do something like this mLocManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);

问题 I am trying to test an Google Map based Android app using RoboScript on Firebase TestLab. By default location is disabled on TestLab devices. To enable them we need to simulate a click on OK button on the system prompt. But this click never happens. You can see the screenshot below. The OK button never gets pressed and flow stops here. I checked the RoboScript json file. Android studio never recorded the OK button click. I tried to create another element like below. But couldn't identify what

问题 I use a started service with the fused api, and implement the location listener directly on it. The Location keeps updating even when the screen is locked, But it stops if the screen goes off. So, is there any way to make sure that the location will keep updating when the screen is off? I read a lot of other questions and I don't really know what i'm missing. public class CLocationService extends Service implements GoogleApiClient.ConnectionCallbacks, LocationListener, GoogleApiClient

问题 This question already has answers here : onLocationChanged() is never trigered by requestLocationUpdate() - Android (2 answers) Closed 2 years ago . I have used manager.requestLocationUpdates("gps", 1800000, 1, new LocationDetector()); method of LocationManager manager = (LocationManager)getSystemService(Context.LOCATION_SERVICE); class for getting update when either location change (device's location) is at least 1 meter (almost 40 inches), OR at least 30 minutes has passed. But the update

问题 For a speed measuring app, I need to get the latitude and longitude updates after every four seconds. I've used the sleep function between the two calls to getLatitude and getLongitude functions. But printing it on screen shows the value remains the same i.e. lon1 and lon2, as doubles (14 places after the decimal) have exactly the same value and hence speed too is shown 0. How to get Latitude and Longitude after fixed intervals of time (4 secs here)? Much thanks in advance. locationManager =
