Android webview whitescreen

Question

I looked it up many times and even changed the Code to something that should work (e.g. verified answer on stackoverflow), but it still doesn't work and I don't know why.

So I created a webView and want it to Display a page. I tried Google.com, but I only get a White space on the window where the webview lays (no Errors, just unclickable White space)

here's my Code:

Main Activity:

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
       /*WebView wv = (WebView) findViewById(R.id.webview);
       wv.setWebViewClient(new MyBrowser());

        wv.loadUrl("http:\\www.google.com");
        */

        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
                this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
        drawer.setDrawerListener(toggle);
        toggle.syncState();

        NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
        if (navigationView != null) {
            navigationView.setNavigationItemSelectedListener(this);
        }

        FragmentManager fragmentManager = getFragmentManager();
        fragmentManager.beginTransaction().replace(R.id.frame_main, new Home()).commit();
        WebView w = (WebView) findViewById(R.id.webview);
        w.getSettings().setJavaScriptEnabled(true);
        w.getSettings().setLoadWithOverviewMode(true);
        w.getSettings().setUseWideViewPort(true);
        w.setWebViewClient(new WebViewClient(){
            @Override
            public boolean shouldOverrideUrlLoading(WebView view,String url){
            view.loadUrl(url);
            return true;
            }
        });
        w.loadUrl("http://www.google.com");
    }

The commented thing was the other Option with same result

I am posting this whole thing here because I think it could maybe have something to do with the fact that I am running a sidebar activity with Fragments.

I also added the permission in manifest, please tell me why it's not working

PS: my phone has working Internet Connection

Here is my XML-File

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:context="myadress.MainActivity"
    tools:showIn="@layout/app_bar_main">

    <WebView
        android:layout_width="match_parent"
        android:layout_height="400sp"
        android:id="@+id/webview"
        tools:layout_editor_absoluteY="0dp"
        tools:layout_editor_absoluteX="8dp">


    </WebView>

</android.support.constraint.ConstraintLayout>

activity main XML

    <FrameLayout

have you tried my answer from here https://stackoverflow.com/a/30392260/3983054 — King of Masses, Jul 25 '17 at 12:16
the Thing is i want to integrate this webview in a normale page but i'll try to see if it at leaast works — ein siedler, Jul 25 '17 at 12:22
there is not very much inside yet because i started with this one and came no further — ein siedler, Jul 25 '17 at 12:27
How xml file with webview is included in activity_main.xml? better paste activity_main too — saty, Jul 25 '17 at 12:32
as i said i am using a Navigation drawer activity so it's split in different frames — ein siedler, Jul 25 '17 at 12:36
Why is webview initialised twice - once by wv and again by w? — Abhi, Jul 25 '17 at 12:42
the first one is commented, this was my first try to get this work it didn't work so i tried another one and just kept the Code commented — ein siedler, Jul 25 '17 at 12:52
I tried your code and the web view is working absolutely fine. Try to load it with "https:....". if that doesn't work try Relative or Linear Layout instead of Constraint layout. — Kartik Shandilya, Jul 25 '17 at 13:02
i even copypasted it into another Project with a single relative layut and nothing else, still not working — ein siedler, Jul 25 '17 at 13:20
could someone just again post a fully finished just copy paste Code for a working webview here? i am not getting why ist not working — ein siedler, Jul 25 '17 at 13:21
