Not calling onPositionUpdate method on Android

Indoor Location
1

Following the tutorial i’ve built this app but, walking around the location, i see the log that i put in the onLocationUpdate method only one time and the position on my mapdoesn’t change.

In the references it’s said that I have to call startPositionig before start scanning and I do it but…how can I start scanning?

Here is my code, any Idea of what’s wrong?

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.content_main);
    xCookie = -100;
    yCookie = -100;
    parametriTrilaterazione = new ParametriTrilaterazione();
    parametriTrilaterazione.setxCookie(-100);
    parametriTrilaterazione.setyCookie(-100);
    EstimoteSDK.initialize(getApplicationContext(), "indoor-location-2jh", "01ceed5427c92df4d956c973adb70e1f");
    cloudManager = new IndoorCloudManagerFactory().create(getApplicationContext(), new EstimoteCloudCredentials("indoor-location-2jh", "01ceed5427c92df4d956c973adb70e1f"));
    b1 = (Button) findViewById(R.id.button);
    crediti = (TextView) findViewById(R.id.crediti);

    b1.setVisibility(GONE);
    crediti.setVisibility(GONE);

    (findViewById(R.id.webview3)).setVisibility(View.GONE);

    web1 = (WebView) findViewById(R.id.webview1);
    web1.setWebViewClient(new WebViewClient());
    web1.loadUrl("https://www.ilmeteo.it/");
    web1.setVisibility(GONE);


    web2 = findViewById(R.id.webview2);
    web2.setWebViewClient(new WebViewClient());
    web1.loadUrl("https://www.ilmeteo.it/");
    web2.setVisibility(GONE);

    tele = true;
    info = true;
    v = (WebView) findViewById(R.id.webview4);
    v.setWebViewClient(new WebViewClient());//Per farlo come WebView e non come browser
    v.addJavascriptInterface(parametriTrilaterazione, "Android");

    CookieSyncManager.createInstance(CONTESTO);
    CookieSyncManager.getInstance().startSync();
    CookieManager.getInstance().setAcceptCookie(true);
    v.getSettings().setJavaScriptEnabled(true);
    // setContentView(v);

    WebSettings webSettings = v.getSettings();
    webSettings.setJavaScriptEnabled(true);

    webSettings.setBuiltInZoomControls(true);
    webSettings.setSupportZoom(true);
    v.getSettings().setDisplayZoomControls(false);
    v.loadUrl("file:///android_asset/index.html");

            yCookie = (int) locationPosition.getY() * 100;
            Log.d("IndoorLocation", "y "+xCookie);
            Log.d("IndoorLocation", "x "+ yCookie);
            parametriTrilaterazione.setxCookie(yCookie);
            parametriTrilaterazione.setyCookie(xCookie);
