ネットワークから場所を取得するウィジェットを作成しています。しかしonLocationChanged()、呼び出されずlocMgr.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, this);に実行されます
また、毎回作成されるウィジェットの新しいインスタンスがあるため、静的が使用されています。
public class MyWidget extends AppWidgetProvider implements LocationListener {
private static LocationManager locMgr;
private static List<String> providers;
private static String bestProvider;
private static Double lat , longt;
public void onEnabled(Context context) {
super.onEnabled(context);
if(locMgr == null) { //Get LocationManager
locMgr = (LocationManager)context.getSystemService(Context.LOCATION_SERVICE);
getLocations();
}
}
public void getLocations() {
//List All providers
providers = locMgr.getAllProviders();
//Get criteria
Criteria criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_FINE);
//Get best provider
bestProvider = locMgr.getBestProvider(criteria, false);
//Get Last known location
//String locationProvider = LocationManager.GPS_PROVIDER;
try {
Location l = locMgr.getLastKnownLocation(bestProvider);
getNewLocation();
}catch(Exception e) {
e.printStackTrace();
System.out.println("error1");
}
}
private boolean getNewLocation() {
System.out.println("aaa");
if(locMgr.isProviderEnabled(LocationManager.NETWORK_PROVIDER)) { //This is executed since it can get locations faster than gps (is executed only if use wireless networks for locations is selected)
System.out.println("bbb");
locMgr.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, this);
return true;
}else {
return false;
}
}
public void onLocationChanged(Location lc) {
System.out.println("ccc");
if(lc!=null) {
lat = lc.getLatitude();
longt = lc.getLongitude();
System.out.println(lat + "xxx " + longt);
//unregister the locationlistener once we get the locations
locMgr.removeUpdates(this);
}else {
}
}
