这是我用来在后台获取GPS坐标的GPS服务。我已经登录了代码的各个区域，以查看哪些位被调用，哪些未被调用。通过单击按钮调用此服务。似乎没有记录该位置的信息，主要问题是有关位置更新的信息，该信息未返回任何信息。
public class SetGPS extends Service {
private LocationListener listener;
private LocationManager locationManager;
@Nullable
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public void onCreate() {
//this is logged successfully
Log.i("LocationListener","is called");
listener = new LocationListener() {
@Override
public void onLocationChanged(Location location) {
Intent i = new Intent("location_update");
i.putExtra("coordinates", location.getLongitude() + " " + location.getLatitude());
sendBroadcast(i);
String latitude = String.valueOf(location.getLatitude());
//this is NOT logged successfully
Log.i("coordinates SetGPS",latitude);
}
@Override
public void onStatusChanged(String s, int i, Bundle bundle) {
}
@Override
public void onProviderEnabled(String s) {
}
@Override
public void onProviderDisabled(String s) {
Intent i = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i);
//this is NOT logged successfully
Log.i("onProviderDisabled","is logged");
}
};
locationManager = (LocationManager) getApplicationContext().getSystemService(Context.LOCATION_SERVICE);
try {
//does NOT successfully log
Log.i("testing","testing");
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 500, 0, listener);
}
catch (SecurityException e){
e.printStackTrace();
}
}
@Override
public void onDestroy() {
super.onDestroy();
if(locationManager != null){
locationManager.removeUpdates(listener);
}
}
}
这是我的清单文件。
