Monitor method and Service question(Android studio)

Hi I used trafficstats(getUidRxBytes(uid)) to get thet network usage, and create a view holder to hold the information and display in list view. I would like to use handler in the Service to get the data in every hours. Below shows the two methods, but I dont know how to combined them together?

In Service

@Override
public void onCreate(){
super.onCreate();
    mHandler = new Handler(){
        @Override
        public void handleMessage(Message msg) {
            super.handleMessage(msg);
            if (msg.what == 1) {
                //float real_data = (float)msg.arg1;
                if(msg.arg1  > 1024 ){
                    System.out.println(msg.arg1 / 1024 + "kb/s");
                }
                else{
                    System.out.println(msg.arg1 + "b/s");
                }
            }
        }
    };

}

private Runnable mRunnable = new Runnable() {
    @Override
    public void run() {   mHandler.postDelayed(mRunnable, count * 10000);
                        Message msg = mHandler.obtainMessage();
                        msg.what = 1;
                        msg.arg1 =rxx;//getNetSpeed();
                        mHandler.sendMessage(msg);

}}

In Activity

private List apps = new ArrayList<ApplicationBean>();
private ListView mListView;

public void getAppTrafficStatList() { PackageManager pm = getPackageManager();
List<PackageInfo> pinfos = pm.getInstalledPackages(PackageManager.GET_UNINSTALLED_PACKAGES |PackageManager.GET_PERMISSIONS); for (PackageInfo info : pinfos) { String[] pers = info.requestedPermissions;

            if (pers != null && pers.length > 0) {
                for (String per : pers)

                    if ("android.permission.INTERNET".equals(per)) {
                        int uid = info.applicationInfo.uid;
                        String lable = (String) info.applicationInfo.loadLabel(pm);

                        Drawable icon = null;
                        try {
                            icon = pm.getApplicationIcon(info.packageName);
                        } catch (PackageManager.NameNotFoundException e) {
                            e.printStackTrace();
                        }

                        long rx = TrafficStats.getUidRxBytes(uid);
                        long tx = TrafficStats.getUidTxBytes(uid);
                        int rxx= (int) rx;
    ApplicationBean app = new ApplicationBean();
    app.setName(lable);
    app.setIcon(icon);
    app.setRx(rx);
    app.setTx(tx);
    apps.add(app);}}

I try to remove the gettrafficstatlist method and move them to the Service file, but then I can not use the private List apps = new ArrayList<ApplicationBean>(); in the Service. I am very confused, can someone help please.
