Disable address bar in Android webview

There is no address bar in a WebView.

If you think you have a WebView, and you see an address bar, that is not your WebView. Rather, you are looking at the Browser application. Most likely, the URL you told the WebView to load did a redirect, and you did not intercept that redirect using a WebViewClient and shouldOverrideURLLoading().

Adding myView.setWebViewClient(new WebViewClient()); disabled the address bar for me.

import android.webkit.WebView;
import android.webkit.WebViewClient;

...

WebView myView = findViewById(R.id.myExampleView);
myView.setWebViewClient(new WebViewClient());
myView.getSettings().setJavaScriptEnabled(true);
myView.loadUrl("https://www.stackoverflow.com");

XML Snippet

<WebView android:id="@+id/myExampleView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:keepScreenOn="true"
    android:gravity="center" />
