我有一个服务来更新我的应用程序中的位置。当我用GPS禁用启动我的应用程序时,返回到android菜单并启用GPS,最后返回到我的应用程序(服务尚未销毁),onProviderEnabled从不被调用。任何人都可以帮忙?位置服务onProviderEnabled从来没有叫
更新:如果我重新启动应用程序提供程序启用。只有onProviderEnabled不叫......
在每一次活动中,我需要的位置我做
super.onCreate(savedInstanceState);
//....
// Bind location service
bindService(new Intent(this, LocationService.class), mConnection, Context.BIND_AUTO_CREATE);
//....
和
@Override
protected void onDestroy() {
super.onDestroy();
// Unbind LocationService
ItemDetail.this.unbindService(mConnection);
}
和服务
public class LocationService extends Service implements LocationListener {
LocationManager locationManager;
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public void onCreate() {
locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)){
// Update after minimum 5 minutes and if user has moved at least 100 meters.
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 5 * 60 * 1000, 100, this);
Location loc = getBestLocation(locationManager);
if(loc!=null){
GlobalVars.lat = (Double) (loc.getLatitude());
GlobalVars.lng = (Double) (loc.getLongitude());
}
}
}
public void onLocationChanged(Location loc) {
GlobalVars.lat = (Double) (loc.getLatitude());
GlobalVars.lng = (Double) (loc.getLongitude());
}
public static Location getBestLocation(LocationManager locationManager) {
Location location_gps = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
Location location_network = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
// If both are available, get the most recent
if(location_gps!=null && location_network !=null) {
return (location_gps.getTime() > location_network.getTime())?location_gps:location_network;
}
else if(location_gps==null && location_network ==null){
return null;
}
else
return (location_gps==null)?location_network:location_gps;
}
public void onProviderEnabled(String s){
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 5 * 60 * 1000, 100, this);
}
public void onProviderDisabled(String s){
locationManager.removeUpdates(this);
GlobalVars.lat = null;
GlobalVars.lng = null;
}
public void onStatusChanged(String s, int i, Bundle b){}
@Override
public void onDestroy() {
locationManager.removeUpdates(this);
}
}
喜!你是否解决了这个问题?我正在寻找像你一样的东西 - 所以我很乐意将你的代码作为参考材料。 我仍然困惑如何使用位置管理器的服务来绕过运行到ANR ... – Chris
