Get GPS Location in a Broadcast Receiver/or Service to Broadcast Receiver data transfer

yes both of them are possible.

your service with a timer to send request to location receiver in periods of time:

public class SrvPositioning extends Service {

    // An alarm for rising in special times to fire the
    // pendingIntentPositioning
    private AlarmManager alarmManagerPositioning;
    // A PendingIntent for calling a receiver in special times
    public PendingIntent pendingIntentPositioning;

    @Override
    public void onCreate() {
        super.onCreate();
        alarmManagerPositioning = (AlarmManager) 
                getSystemService(Context.ALARM_SERVICE);
        Intent intentToFire = new Intent(
                ReceiverPositioningAlarm.ACTION_REFRESH_SCHEDULE_ALARM);
        intentToFire.putExtra(ReceiverPositioningAlarm.COMMAND,
                ReceiverPositioningAlarm.SENDER_SRV_POSITIONING);
        pendingIntentPositioning = PendingIntent.getBroadcast(this, 0,
                intentToFire, 0);
    };

    @Override
    public void onStart(Intent intent, int startId) {
        try {
            long interval = 60 * 1000;
            int alarmType = AlarmManager.ELAPSED_REALTIME_WAKEUP;
            long timetoRefresh = SystemClock.elapsedRealtime();
            alarmManagerPositioning.setInexactRepeating(alarmType,
                    timetoRefresh, interval, pendingIntentPositioning);
        } catch (NumberFormatException e) {
            Toast.makeText(this,
                    "error running service: " + e.getMessage(),
                    Toast.LENGTH_SHORT).show();
        } catch (Exception e) {
            Toast.makeText(this,
                    "error running service: " + e.getMessage(),
                    Toast.LENGTH_SHORT).show();
        }
    }

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

    @Override
    public void onDestroy() {
        this.alarmManagerPositioning.cancel(pendingIntentPositioning);
        ReceiverPositioningAlarm.stopLocationListener();
    }
}

your receiver with a listener. listener can be used in your activity to be notified that a new location is ready for you:

public class ReceiverPositioningAlarm extends BroadcastReceiver {

    public static final String COMMAND = "SENDER";
    public static final int SENDER_ACT_DOCUMENT = 0;
    public static final int SENDER_SRV_POSITIONING = 1;

                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
        public void onProviderEnabled(String provider) {}

        @Override
        public void onProviderDisabled(String provider) {}

        @Override

    // received request from the calling service
    @Override
    public void onReceive(final Context context, Intent intent) {
        Toast.makeText(context, "new request received by receiver",
                Toast.LENGTH_SHORT).show();
        _context = context;
        _intent = intent;
        locationManager = (LocationManager) context
                .getSystemService(Context.LOCATION_SERVICE);
        if (locationManager.isProviderEnabled(provider)) {

            Location gotLoc = locationManager

            gotLocation(gotLoc);
        } else {
            Toast t = Toast.makeText(context, "please turn on GPS",

            _context.startActivity(settinsIntent);
        }
    }

    private static void gotLocation(Location location) {
        prevLocation = currentLocation == null ? null : new Location(

    // listener ----------------------------------------------------
    static ArrayList<OnNewLocationListener> arrOnNewLocationListener = 
            new ArrayList<OnNewLocationListener>();

    // Allows the user to set a OnNewLocationListener outside of this class
    // and react to the event.
    // A sample is provided in ActDocument.java in method: startStopTryGetPoint
    public static void setOnNewLocationListener(
            OnNewLocationListener listener) {

    }

    public static void clearOnNewLocationListener(

    }

    // This function is called after the new point received
    private static void OnNewLocationReceived(Location location) {
        // Check if the Listener was set, otherwise we'll get an Exception
        // when we try to call it
        if (arrOnNewLocationListener != null) {
            // Only trigger the event, when we have any listener
            for (int i = arrOnNewLocationListener.size() - 1; i >= 0; i--) {
                arrOnNewLocationListener.get(i).onNewLocationReceived(
                        location);
            }
        }
    }
}

an interface for listener:

import android.location.Location;

public interface OnNewLocationListener {
    public abstract void onNewLocationReceived(Location location);
}

in your activity for getting just one point:

protected void btnGetPoint_onClick() {
    Intent intentToFire = new Intent(
            ReceiverPositioningAlarm.ACTION_REFRESH_SCHEDULE_ALARM);
    intentToFire.putExtra(ReceiverPositioningAlarm.COMMAND,
            ReceiverPositioningAlarm.SENDER_ACT_DOCUMENT);
    sendBroadcast(intentToFire);
    OnNewLocationListener onNewLocationListener = new OnNewLocationListener() {

        @Override
        public void onNewLocationReceived(Location location) {
            // use your new location here then stop listening
            ReceiverPositioningAlarm.clearOnNewLocationListener(this);
        }
    };
    // start listening for new location
    ReceiverPositioningAlarm
            .setOnNewLocationListener(onNewLocationListener);
}

edit:

if you want to start service in your activity:

this.startService(new Intent(this, SrvPositioning.class));

similarly you can define a listener in your service to receive locations found by receiver

Edit

Add the following lines in Manifest

<service
            android:name="org.mabna.order.services.SrvPositioning"
            android:enabled="true" />

<receiver android:name="org.mabna.order.receivers.ReceiverPositioningAlarm" >

            <!-- this Broadcast Receiver only listens to the following intent -->
            <intent-filter>
                <action android:name="org.mabna.order.ACTION_REFRESH_SCHEDULE_ALARM" />
            </intent-filter>
        </receiver>
