问题 I want to receive the coordinates of the points that are in the kml file. I created a object that receives the coordinates but I can not find how to take them from the file. An example of what has been done so far: (The amount of points is 132, but I shortened it to be able to present here.) Kml file: <LinearRing> <coordinates> 34.79991805485883,32.070779943443,0 34.799829164854,32.07080649750882,0 34.79971023480251,32.07083335300256,0 34.79959122858838,32.07086022634235,0 34.79947508289758

问题 I have an application that is required to log the user's location every couple of seconds, the entire time it is on. On does not mean in the foreground,or that even the Android's screen is on. What is the suggested way to accomplish it? I've heard of background and foreground services, and also saw something about Jobs. I also saw this was possible with a WakeLock. I am not sure what is the best method of choice. The need to conserve Battery life is of course an issue. 回答1: You should use

问题 In my application, I am calling gps setting menu if gps is not enabled. I called this in Oncreate() method. However, I also wants to check whether user actually enables it or not? My Question is which activity life cycle method gets called when user get back from setting menu. I tried to write code for OnResume method. But alertdilogue keeps poping even GPS is enabled. if (gps.canGetLocation()) { latitude = gps.getLatitude(); longitude = gps.getLongitude(); altitude = gps.getAltitude();

问题 I know that this question is asked many times in SO,and I've tried to follow 20 web page content.. page 1 page 2 page 3 page 4 etc etc pages...

问题 I am creating a geolocation app with Intel XDK (iPhone and Android) and have 2 questions: How can I display the geolocation settings of the device if the GPS is not active on the phone? How do I know if the latitude and longitude values returned are from the GPS or from the wifi/data coords? I figured that wifi/data returns a short value (eg: 43.475748) and GPS returns a longer value (eg: 43.47573849384) Am I correct in thinking this? 回答1: 1.) Most devices will cache the last known geo

问题 I'm using a Reach RS+ device to capture GPS position data as well as IMU data (roll, pitch and yaw); see the "Point Collection" image on the manufacturer's website. I'm trying to determine the GPS coordinates of the bottom point (the empty end of the rod that the receiver is fixed on). To be able to make calculations in meters I'm converting longitude ( X ) and latitude ( Y ) to UTM while keeping altitude ( Z ) unaltered. When the rod is upright, X and Y stay the same while Z1 = Z - ROD
