android webview show credentials popup

Here is the link where I want to login:
http://audidome-dev.webspaces.vektorrausch.net/app/login.php
and in normal browser it looks so
but I can't get this popup in my WebView.
Here is my code:
mWebView = (WebView) findViewById(R.id.webView);
WebSettings webSettings = mWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setJavaScriptCanOpenWindowsAutomatically(true);
webSettings.setDomStorageEnabled(true);
mWebView.setWebViewClient(new WebViewClient());
mWebView.setWebChromeClient(new WebChromeClient());
mWebView.setVisibility(View.VISIBLE);
mWebView.loadUrl("http://audidome-dev.webspaces.vektorrausch.net/app/login.php");

WebView won't display this pop-up. It will ask you for the credentials and it's up to you to fill the credentials (display the pop-up).

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?

Is there a way to enable JavaScript in a WebView?
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.

Android WebView - code that can display and play a podcast can't play a YouTube video

I have this code which works to display a WebView and use it:
WebView webview = null;
#Override
public void onCreate(Bundle savedInstanceState)
{
//setTheme(R.style.Theme_Sherlock_Light);
super.onCreate(savedInstanceState);
//setContentView(R.layout.podcasts);
webview = new WebView(this);
webview.getSettings().setAppCacheEnabled(false);
webview.getSettings().setJavaScriptEnabled(true);
webview.setInitialScale(1);
webview.getSettings().setPluginState(PluginState.ON);
webview.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
});
//webSettings.setBuiltInZoomControls(true);
WebSettings webSettings = webview.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setBuiltInZoomControls(true);
//webSettings.getMediaPlaybackRequiresUserGesture();
webSettings.setAllowContentAccess(true);
webSettings.setEnableSmoothTransition(true);
webSettings.setLoadsImagesAutomatically(true);
webSettings.setLoadWithOverviewMode(true);
webSettings.setSupportZoom(true);
webSettings.setUseWideViewPort(true);
setContentView(webview);
webview.loadUrl("url_to_go_to");
But when I try to use this code to point to a YouTube channel, it just shows a blank screen.
Any idea why that would happen?
Thanks!

In order to get HTML5 videos to show up you need to enable the following things in the WebView:
WebView view;
... //initialize WebView
WebSettings webViewSettings = view.getSettings();
view.setWebChromeClient(new WebChromeClient(){}); //just added this
webViewSettings.setDomStorageEnabled(true);
webViewSettings.setAppCacheEnabled(true);
webViewSettings.setAppCachePath(getApplicationContext().getFilesDir().getAbsolutePath() + "/cache");
webViewSettings.setDatabaseEnabled(true);
webViewSettings.setDatabasePath(getApplicationContext().getFilesDir().getAbsolutePath() + "/databases");
You also need to put android:hardwareAccelerated="true" in your AndroidManifest. Otherwise, HTML5 stuff like YouTube videos won't work.

Android WebView - when trying to play a YouTube video, screen is black but audio plays

I am trying to play a YouTube channel from a WebView. It feels like I almost got it but I have two problems. Because there is some redirect when trying to load the YouTube channel url, the shouldOverrideUrlLoading method seems to be breaking things and I just get a gray screen.
And the other problem is that if I comment out that line and the Channel loads, when I play the videos, the video seems to load, and the audio plays, but the screen of the youtube stays black.
Here is my code
public class YoutubeActivity extends BaseActivity
{
WebView webview = null;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
webview = new WebView(this);
webview.getSettings().setAppCacheEnabled(false);
webview.getSettings().setJavaScriptEnabled(true);
webview.setInitialScale(1);
webview.getSettings().setPluginState(PluginState.ON);
webview.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
});
WebSettings webSettings = webview.getSettings();
webSettings.setEnableSmoothTransition(true);
webSettings.setLoadsImagesAutomatically(true);
webSettings.setLoadWithOverviewMode(true);
webSettings.setBuiltInZoomControls(true);
webSettings.setAllowContentAccess(true);
webSettings.setSupportZoom(true);
webSettings.setUseWideViewPort(true);
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/g33ktalktv");
Would anyone know how to fix this?
Thank you!
