I initialize the location listener on creation but I can't figure out how to change these parameters or even find out if it's possible to do that. The main purpose for this would be to conserve battery life when the program doesn't need regular position updates. Thanks so much for your help! -Dom 回答1: I'm not sure if this is correct, but faced with the

This is the code: LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE); Location location = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER); double longitude = location.getLongitude(); double latitude = location.getLatitude(); Log.d("LOCATION1", "Longitude: " + longitude); Log.d("LOCATION2", "Latitude: " + latitude); Sometimes I do get both coordinates, but not always, which

I know the iPhone can and does use WiFi proximity to get approximate location. This obviously only can occur when some database in the sky knows the approximate location of that WiFi hotspot. My question is how do hotspots get into that db? Is it automatically added whenever the iPhone has a reasonably accurate GPS position and detects the WiFi or is there some manual or programatic way of adding hotspots? Apple uses their own database since iOS 3.2 (prior to that they used Skyhook Wireless). This works by sending WiFi MAC addresses to Apple by GPS-enabled iOS devices. So if the device has a

Part of a future project of mine is to make my app be able to record the current location using GPS possibly on both Android and iOS. Can the GPS coordinates be taken in "Universal Transverse Mercator" format like in Google Earth for both platforms? If not, is there some way to calculate the coordinates to this format? EDIT: Any chance anyone would know what format the functions in their respective APIs return? 回答1: The API will provide a location object (class

This all works fine because i want a location quickly and with GPS Provider it takes ages. But I've come to a point in my app where location has to be accurate (max 5-10meters). I was wondering if it's possible to use the GPS provider with the Network Provider at the same time and then get the best result of both? And is it also possible to let me know when the GPS provider provided me with an GPS Location? So basically: LocationManager lm = (LocationManager)

He sent me few screen shots and they made me think; LocationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER) is not working properly. His phone is running Android 4.1.2 and first I thought this is the cause of this issue. But it was not the case. He sent me a screen shot of that setting too. Then I googled and found this . The question seems to help me but unfortunately answer was not helpful for this case and questioner did not pursue

However it's not clear to me if a wakelock prevent doze mode or not. 回答1: Based on some testing, using a Nexus 5 with the the final(?) preview of Android 6.0 installed: Holding a PARTIAL_WAKE_LOCK is insufficient to block Doze mode ― the device will still doze, even though you have the WakeLock and are trying to do regular work (e.g., setExactAndAllowWhileIdle() to get control every minute) Keeping the screen on using android:keepScreenOn
