接近警报仅触发警报一次

Question

我想获取当前位置并向该位置添加邻近警报。当我退出或输入当前位置周围的半径时。当我获取当前位置的纬度和经度并添加邻近警报时，我在注册后立即收到警报。但是即使我在前台，当我退出时，我也不会得到。我已经在清单中注册了我的收款人。

这是我的活动。

    public class GeoFencer extends FragmentActivity implements LocationListener {
    private LocationManager locMan, locManForProximitySensor;
    private Intent i;
    private PendingIntent pService;
    Context context;

    @Override
    protected void onCreate(Bundle arg0) {
        setContentView(R.layout.geo_fencer_layout);
        super.onCreate(arg0);
        context = this;
        locMan = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
        locManForProximitySensor = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
        i = new Intent("com.packagename.proximity");
        pService = PendingIntent.getBroadcast(this, 0   , i, 0);
    }
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // TODO Auto-generated method stub
        MenuInflater inflater= getMenuInflater();
        inflater.inflate(R.menu.geofencemenu, menu);
        return true;
    }
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if(item.getItemId() == R.id.action_geo){
            if(locMan.isProviderEnabled(LocationManager.NETWORK_PROVIDER)){
                locMan.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, this);
            }
            else if(locMan.isProviderEnabled(LocationManager.GPS_PROVIDER)){
                locMan.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);
            }
            else
                Toast.makeText(this, "GPS is disabled. Please Enable.", Toast.LENGTH_LONG).show();
        }
        return super.onOptionsItemSelected(item);
    }
    @Override
    public void onLocationChanged(Location location) {

        locManForProximitySensor.addProximityAlert(location.getLatitude(), location.getLongitude(), 10, -1 , pService) ;
        Log.d(getClass().getSimpleName(),"Proximity alert added (" + location.getLatitude() + ", "+ location.getLongitude() + ")");
        locMan.removeUpdates(this);
    }
    @Override
    public void onStatusChanged(String provider, int status, Bundle extras) {
        // TODO Auto-generated method stub
    }
    @Override
    public void onProviderEnabled(String provider) {
        // TODO Auto-generated method stub
    }
    @Override
    public void onProviderDisabled(String provider) {
        // TODO Auto-generated method stub
    }
}

   public class ProximityAlertReceiver extends BroadcastReceiver{
    private static final int NOTIFICATION_ID = 1000;
    @Override
    public void onReceive(Context context, Intent intent) {
        String key = LocationManager.KEY_PROXIMITY_ENTERING;
        String message  = " ";
        Boolean entering = intent.getBooleanExtra(key, false);
        if (entering) {
            Log.d(getClass().getSimpleName(), "entering");
            message = "You are entering your point";
        }
        else {
            Log.d(getClass().getSimpleName(), "exiting");
            message = "You are exiting your point";
        }

        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(context)
                .setSmallIcon(R.drawable.app_icon)
                .setContentTitle("CompanyName")
                .setContentText(message);

        NotificationManager mNotificationManager =
            (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        // mId allows you to update the notification later on.
        mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
    }
}

请告诉我我在这里做错了什么。谢谢阿达文斯。
