Getting troubles making status bar hovering the activity

Question

I have a web site, and I decided to make an Android application for it, but I actually write under win32 on c++, and have never programming under Android. So I decided to make just a Blink render instance, fit it the screen size in my app and load automatically my site. Also I want the status bar hovering on the "activity", searched the internet but can't do this, so please point me, where am I wrong. Stuff should work from Android 4.4 and above. Working in Android Studio

What do I have now:

What do I want to:

My code:

    getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE|View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);

    WebView myWebView = findViewById(R.id.webview);

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

Try this on onCreate this will make both transparent

getWindow().setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);

or try

getWindow().setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION,WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS,WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
