WebView for Android (Java).

Sample code (MainActivity.java) for WebView Android application.

public class MainActivity extends AppCompatActivity {
    //Overriding navigation buttons
    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if ((keyCode == KeyEvent.KEYCODE_BACK) && webView.canGoBack()) {
            webView.goBack();
            return true;
        }
        return super.onKeyDown(keyCode, event);
    }
	
    WebView webView;
    @SuppressLint("SetJavaScriptEnabled") //disables JavaScript enable warning
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //bottom navigation bar
        Window w = getWindow();
        w.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);

        //disables the night theme
        AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_NO);

        //expands the application to full screen
        supportRequestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

        //applies the layout to the current screen
        setContentView(R.layout.activity_main);
        webView = new WebView(this);

        //new settings for WebView element
        WebSettings webSettings = webView.getSettings();
        webSettings.setJavaScriptEnabled(true);
        webSettings.setAllowFileAccess(true); //opens internal pages in the application
        webSettings.setCacheMode(WebSettings.LOAD_NO_CACHE); //caching settings
        webView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);

        //create a new WebViewClient
        webView.setWebViewClient (new WebViewClient() {
            public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request){
                if ("your-website.com".equals(request.getUrl().getHost())) {
                    //your website "your-website.com" 
                    return false;
                }
                webView.stopLoading();
                Intent intent = new Intent(Intent.ACTION_VIEW, request.getUrl());
                startActivity(intent);
                return true;
            }  

        });  

        webView.loadUrl("http://your-website.com/"); //your website "your-website.com"
        //You can also download your html page from the Assets directory. 
        //webView.loadUrl(("file:///android_asset/index.html"));
        setContentView(webView);

    }
}
						

Everything is simple, if you don’t complicate anything!

Here is a sample code (MainActivity.java) for a WebView Android application... WebView allows developers to bridge the gap between web technologies and native Android technologies!
