gps

In blackberry, we use a timeout to get the location, so that if it doesnt retun location in that much time period, we get to know. But in Android, there is no concept of timeout, can anyone please tell the alternative, that we can find out that after this much time there is no location update from GPS. You can use two threads for this timeout. One thread tries to get the GPS fix and the other (timeout) thread, once it reaches the timeout specified, removes the registration of your application to receive location updates from the location listener. 来源： https://stackoverflow.com/questions

I am developing a web application using JQuery Framework and am using Geolocation to determine the locations of our hardware stations to display on Google Maps. In our database the locations of the sites are stored in Southing/Easting format. I need a way to convert Southing/Easting coordinates to Latitude/Longitude that Google Maps can understand. Can anyone please tell me the formula or the best way to approach this problem? I have done searches on Southing/Easting however nothing came up, more like northing/westing etc and even then, not much info.. The programming part I don't really need

I'm writing a simple GPS based app for location awareness. Whenever GPS is enabled, the app requests location updates and prints latitude and longitude in a TextView . If GPS is disabled, the location provider fall-backs to LocationManager.NETWORK_PROVIDER for triangulating device position relative to neighboring cell-towers. The aim is whenever device movement is detected, it should start populating the TextView with lat/long. When there is no movement, the process should stop. In order to do so, I've implemented the location update rate as: locationManager.requestLocationUpdates

My question is how does google map or mobile GPS able to find mine current location ? My high level understanding after reading this article is , GPS receiver gets the location coordinates through these satellites and this location is further passed to Google Map(or any other client) API which then locates the exact location on map. Is it correct ? Somewhere i also read that Mobile towers also plays the role. But my unserstanding is that this can be used to track the mobile location if required but mobile apps or Google maps uses the satellite approach. Right ? Matej P. It's a bit inaccurate

I'm currently using GPS only to get current location of the user to return certain results. As in Belgium, if you're inside, most of the time you can't get GPS-connection. So I want to get the current location with the wifi-connection. I've found this example: get the current location (gps/wifi) But I'm not sure which lines tell the device which connection to choose. I'm guessing it's this one: String provider = myLocationManager.getBestProvider(criteria,true); That I've to add to my code. When I check what's inside of this, I always get a null-value, I don't quite understand why. My code
