Android GPS module is gps.default.so in the system/lib/hw/directory, general GPS-enabled mobile phones should implement this module and real GPS hardware interactionthe GPS in QEMU is to construct a gps.default.so, but this so does not deal with real hardware, just an analog

Recently, I am working on an Android project and need to use GPS to obtain location information. I checked the information from the API and found that obtaining location information only requires an extremely simple sentence: Copy codeThe Code is as follows: getLastKnownLocation (LocationManager. GPS_PROVIDER ), So I was so happy. But once written into the code,

(event==gpsstatus.gps_event_satellite_status) { //Satellite status change Gpsstatus gpsstauts= locationmanager.getgpsstatus (null); //Take current status int maxsatellites = Gpsstauts.getmaxsatellites (); //Get the default maximum number of satellites Iterator//Create an iterator to save all satellites int count = 0; While (It.hasnext () count count++; Gpsstatellite s = it.next (); } System.out.println ("Search to:" +count+"satellite"); }Else if (event==gpsstatus.gp

The gps function provided by android allows you to conveniently obtain location information. Because this is the gps used in the simulator again, the gps location information should be sent through ddms.The main. xml file has only one textview node and is not provided. The following permissions are required to operate

Cons: Fee Electricity//0 means passive Mode 1 means network Mode 2 means GPS mode 3 means mixed mode Pub
