Невозможно получить доступ к местоположению в AsynTask при использовании с широковещательным приемником, тревогой и ожидающими намерениями

Я использую Broadcast Receiver и Alarm with Pending Intent, чтобы запустить мою службу на BOOT_COMPLETE с некоторым фиксированным таймером. И я предоставляю статические значения переменной, а затем передаю их на веб-сервер (сервлет), пока этот мой код работает нормально ... но когда я добавляю Диспетчер местоположения, чтобы получить реальные координаты, приложение вылетает !! ошибка :: NULLPOinterException, !!! подскажите где я не прав!! будет самым детским.. спасибо !! [также хочу открыть камеру, когда ответ получен от сервлета, о чем я упоминал в комментарии внутри кода! ]

Это мой широковещательный приемник

    public class StartAtBootServiceReceiver extends BroadcastReceiver 
{

    // receives BOOT_COMPLETed from manifest ,,plus added here Alarm
    public void onReceive(Context context, Intent intent) 
    {

        Calendar cal = Calendar.getInstance();
        Intent srvIntent = new Intent(context, StartAtBootService.class);

        PendingIntent pIntent = PendingIntent.getService(context, 0, srvIntent,0);
        // Use context argument to access service
        AlarmManager alarm = (AlarmManager) context
                .getSystemService(Context.ALARM_SERVICE);

        // Repeat every 5 seconds
        alarm.setInexactRepeating(AlarmManager.RTC_WAKEUP,
                cal.getTimeInMillis(), 10000, pIntent);
    }

}

Это мой класс службы Java

    }

        // Get LocationManager object from System Services LOCATION_SERVICES
        lm = (LocationManager) getSystemService(LOCATION_SERVICE);

        // create a criteria object to retrieve provider
        Criteria criteria = new Criteria();

        // Get the name of the best provider
        String provider = lm.getBestProvider(criteria, true);

        // Get current Location
        Location myLocation = lm.getLastKnownLocation(provider);

        // get latitude of the current location
        latitude = myLocation.getLatitude();

        // get longitude of the current location
        longitude = myLocation.getLongitude();

        Toast.makeText(this, "onStart tryyyy", Toast.LENGTH_LONG).show();

        deviceInfo(); // my method for getting imei
