android - start service on boot

Question

I am using toggleButton in my code for start/stop service. I start service using togglebutton. but when I reboot my phone I want the toggleButton to be on i.e service is started as soon as phone is on. This is my code.

    public void onCreate(Bundle savedInstanceState) {
    Toast.makeText(getApplicationContext(),"in OnCreate", Toast.LENGTH_LONG).show();
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    // setAppInfo();
    dba = new DBAdapter(this);
    //toggleLogging(AppSettings.getServiceRunning(MainActivity.this),
    //AppSettings.getLoggingInterval(MainActivity.this));
    addButtonListeners();
    enableControls();
    try {
        SharedPreferences preferences = getSharedPreferences(PREFS_NAME, 0);
        String installDate = preferences.getString("FirstRun", null);
        if (installDate == null) {
            TelephonyManager tm = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
            imeino = tm.getDeviceId();
            String model = getDeviceName();
            SmsManager smsManager = SmsManager.getDefault();
            SharedPreferences.Editor editor = preferences.edit();
            sdf = new SimpleDateFormat("yyyy-MM-dd");
            String dateString = sdf.format(new Date(System
                    .currentTimeMillis()));
            editor.putString("FirstRun", dateString);
            editor.commit();
        } else {
        }
    }// end of try
    catch (Exception e2) {
        e2.printStackTrace();
    }
