Ortungsdienst GPS Force geschlossen
Hallo, ich entwickle eine App, um den besten Standort zu finden und eine SMS an eine Nummer zu senden. Es funktioniert gut mit dem Netzwerkstandort, aber wenn ich mit GPS oder der Kriterienklasse suchen möchte, wird es automatisch geschlossen. Es ist so nett von dir, mir zu helfen.
package ir.M410.toolkit;
import android.app.Service;
import android.content.Intent;
import android.location.Criteria;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.os.IBinder;
import android.telephony.SmsManager;
import android.util.Log;
public class LocationFinder extends Service implements LocationListener{
double lat ,lon ;
@Override
public IBinder onBind(Intent arg0) {
return null;
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
// We want this service to continue running until it is explicitly
// stopped, so return sticky.
LocationManager mlocationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
Criteria criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_FINE);
criteria.setPowerRequirement(Criteria.POWER_MEDIUM);
String locationprovider = mlocationManager.getBestProvider(criteria, true);
Location mlocation = mlocationManager.getLastKnownLocation(locationprovider);
lat = mlocation.getLatitude ();
lon = mlocation.getLongitude ();
Log.i("Geo_Location", "Latitude: " + lat + ", Longitude: " + lon);
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage("+11231233213", null,"https://maps.google.com/maps?q="+lat+","+lon, null, null);
// SmsManager sms = SmsManager.getDefault();
//sms.sendTextMessage(MainActivity.senderNum, null," "+"lat:"+lat+" "+"lon:"+lon, null, null);
//stopSelf();
return START_NOT_STICKY;
}
@Override
public void onLocationChanged(Location location) {
// TODO Auto-generated method stub
lat= location.getLatitude();
lon =location.getLongitude();
Log.i("Geo_Location", "Latitude: " + lat + ", Longitude: " + lon);
// stopSelf();
}
@Override
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub
}
@Override
public void onDestroy() {
super.onDestroy();
}
}
und das ist mein manifest:

Der zu überprüfende [bearbeitete] Code ist nicht null:
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
// We want this service to continue running until it is explicitly
// stopped, so return sticky.
LocationManager mlocationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
Criteria criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_FINE);
criteria.setPowerRequirement(Criteria.POWER_MEDIUM);
String locationprovider = mlocationManager.getBestProvider(criteria, true);
if(mlocationManager.getLastKnownLocation(locationprovider)!=null){
Location mlocation = mlocationManager.getLastKnownLocation(locationprovider);
lat = mlocation.getLatitude ();
lon = mlocation.getLongitude ();
Log.i("Geo_Location", "Latitude: " + lat + ", Longitude: " + lon);
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage("+11231233213", null,"https://maps.google.com/maps?q="+lat+","+lon, null, null);
}
und es ist in Ordnung und wird nicht erzwungen, aber es werden keine Daten empfangen. Es ist immer null !!
