Send location in Broadcast Receiver

Question

I wanna send location via sms from Broadcast Receiver. The code doesn't work at all in determining my location. Anyone can help me to solve my problem?

SmsRemoteController

public class SmsRemoteController extends BroadcastReceiver {
    private static final int MODE_WORLD_READABLE = 1;
    private String smsFirstCode;
    private SharedPreferences myPrefs;
    private Context contexts;
    private String sendingNumber = "";


    @Override
    public void onReceive(Context context, Intent intent) {
        contexts = context;
        myPrefs = context.getSharedPreferences("myPrefs", MODE_WORLD_READABLE);
        String smsMode = myPrefs.getString("state", "not");
        AppLocationService appLocationService;
        appLocationService = new AppLocationService(SmsRemoteController.class);

        if (smsMode.equals("ON")) {

            Bundle bundle = intent.getExtras();
            SmsMessage[] msgs = null;
            String smsBody = "";
            if (bundle != null) {
                Object[] pdus = (Object[]) bundle.get("pdus");
                msgs = new SmsMessage[pdus.length];
                for (int i = 0; i < pdus.length; i++) {
                    msgs[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
                    sendingNumber += msgs[i].getOriginatingAddress();
                    smsBody = msgs[i].getMessageBody().toString();
                }

                // Toast.makeText(contexts, "number"+sendingNumber+"..body"+smsBody.toLowerCase(), Toast.LENGTH_SHORT).show();


                if (smsBody.equals("locate")) {


                    Location nwLocation = appLocationService.getLocation(LocationManager.NETWORK_PROVIDER);

                    if (nwLocation != null) {
                        double latitude = nwLocation.getLatitude();
                        double longitude = nwLocation.getLongitude();
                        Toast.makeText(contexts, "Mobile Location (NW): \nLatitude: " + latitude + "\nLongitude: " + longitude,
                                Toast.LENGTH_LONG).show();

                    } else {
                        Location gpsLocation = appLocationService.getLocation(LocationManager.GPS_PROVIDER);

                        if (gpsLocation != null) {
                            double latitude = gpsLocation.getLatitude();
                            double longitude = gpsLocation.getLongitude();
                            Toast.makeText(contexts, "Mobile Location (GPS): \nLatitude: " + latitude
                                            + "\nLongitude: " + longitude,
                                    Toast.LENGTH_LONG).show();
                        }

                    }


                }
                //abortBroadcast();
            }// end of onReceive()


        }

    } // end of the class
}

AppLocationService

public class AppLocationService extends Service implements LocationListener {

    protected LocationManager locationManager;
    Location location;

    private static final long MIN_DISTANCE_FOR_UPDATE = 10;
    private static final long MIN_TIME_FOR_UPDATE = 1000 * 60 * 2;

    public AppLocationService(Context context) {
        locationManager = (LocationManager) context.getSystemService(LOCATION_SERVICE);
    }

    public Location getLocation(String provider) {
        if (locationManager.isProviderEnabled(provider)) {
            locationManager.requestLocationUpdates(provider,MIN_TIME_FOR_UPDATE, MIN_DISTANCE_FOR_UPDATE, this);
            if (locationManager != null) {
                location = locationManager.getLastKnownLocation(provider);
                return location;
            }
        }
        return null;
    }

    @Override
    public void onLocationChanged(Location location) {
    }

    @Override
    public void onProviderDisabled(String provider) {
    }

    @Override
    public void onProviderEnabled(String provider) {
    }

    @Override
    public void onStatusChanged(String provider, int status, Bundle extras) {
    }

    @Override
    public IBinder onBind(Intent arg0) {
        return null;
    }

}

@sud I can't pass the location from service to BroadcastReceiver. The error in this line 'appLocationService = new AppLocationService(SmsRemoteController.class)' — nicholas how, Dec 02 '15 at 05:16
try this `appLocationService = new AppLocationService(this.SmsRemoteController)' — sud, Dec 02 '15 at 05:59
@sud still displayed error: "cannot find symbol variable SmsRemoteController" Previously error was: "incompatible types: SmsRemoteController cannot be converted to Context" — nicholas how, Dec 02 '15 at 06:09
ok now do this this will defenitly work `appLocationService = new AppLocationService(contexts)` — sud, Dec 02 '15 at 06:17
OMG THANKS sud! My code is totally working smooth now! Thank you so very much. — nicholas how, Dec 02 '15 at 06:25

The way you are calling service is not preferred way of using Service, We never creates object of service in the BoradcastReceiver So you can register for a Location receiver and based on the updated value you receive you can show the Toast of perform required operation. I have updated below one of the possible solution for your requirement.

Also I would still prefer to start a service from the Broadcast receiver for getting the location as we should not be heavy operation on the BroadcastReceiver,

public class SmsRemoteController extends BroadcastReceiver {
    private static final int MODE_WORLD_READABLE = 1;
    private String smsFirstCode;
    private SharedPreferences myPrefs;
    private Context contexts;
    private String sendingNumber = "";
    public static final int MIN_TIME_REQUEST = 5 * 1000;
    public static final String ACTION_REFRESH_SCHEDULE_ALARM =
                    "org.mabna.order.ACTION_REFRESH_SCHEDULE_ALARM";
    private static Context _context;
    private static LocationManager locationManager;


    private static LocationListener locationListener = new LocationListener() {

        @Override
        public void onStatusChanged(String provider, int status, Bundle extras){
            try {
                String strStatus = "";
                switch (status) {
                case GpsStatus.GPS_EVENT_FIRST_FIX:
                    strStatus = "GPS_EVENT_FIRST_FIX";
                    break;
                case GpsStatus.GPS_EVENT_SATELLITE_STATUS:
                    strStatus = "GPS_EVENT_SATELLITE_STATUS";
                    break;
                case GpsStatus.GPS_EVENT_STARTED:
                    strStatus = "GPS_EVENT_STARTED";
                    break;
                case GpsStatus.GPS_EVENT_STOPPED:
                    strStatus = "GPS_EVENT_STOPPED";
                    break;
                default:
                    strStatus = String.valueOf(status);
                    break;
                }
                Toast.makeText(_context, "Status: " + strStatus,
                        Toast.LENGTH_SHORT).show();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }

        @Override

        @Override

        @Override

            try {
                Toast.makeText(_context, "***new location***",
                        Toast.LENGTH_SHORT).show();

Hi Pratik Goyal, I've try your code but my apps crash when it receiving incoming sms. Why it happen? Should i do something in manifests? — nicholas how, Dec 02 '15 at 05:13
Can you please share the error that you are seeing in the Logs — Pratik Goyal, May 05 '16 at 06:19
