Android - can't seem to enable JavaScript on a WebView?

Is there a way to enable JavaScript in a WebView?

I am currently trying to enable JavaScript by doing this:

@Override
public void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);   
    webview = new WebView(this);
    setContentView(webview);

    webview.getSettings().setAppCacheEnabled(false);
    webview.getSettings().setJavaScriptEnabled(true);
    webview.setInitialScale(1);
    webview.getSettings().setPluginState(PluginState.ON);

    WebSettings webSettings = webview.getSettings();

    webSettings.setLoadsImagesAutomatically(true);
    webSettings.setLoadWithOverviewMode(true);
    webSettings.setBuiltInZoomControls(true);  
    webSettings.setUseWideViewPort(true);

    webview.setWebViewClient(new WebViewClient() {
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);              
            return false;
        }
    });        


    webview.setWebChromeClient(new WebChromeClient(){});

    webSettings.setJavaScriptEnabled(true);
    webSettings.setDomStorageEnabled(true);
    webSettings.setAppCacheEnabled(true);
    webSettings.setAppCachePath(getApplicationContext().getFilesDir().getAbsolutePath() + "/cache");
    webSettings.setDatabaseEnabled(true);
    webSettings.setDatabasePath(getApplicationContext().getFilesDir().getAbsolutePath() + "/databases");


    webview.loadUrl("http://www.youtube.com/user/Okudjavavich");    
}

But JS seems to not be enabled because the YouTube videos do not play YouTube ads. Would anyone know what may be the problem?

Yes, via the code that you have:

webview.getSettings().setJavaScriptEnabled(true);

In your case, the problem was that your test (playing YouTube videos and looking for ads) was complicated. A simpler test helped determine that JavaScript indeed was enabled, but that something else was influencing Google's YouTube page-serving. In this case, it appears to be based on user agent.
