window.close（）无法在android webview中运行？

Question

Android 4.1 Eclipse Testing on device

I am trying to open a html/javascript webpage, hosted on my localhost for now, in my android application through a webview. The page is suppose to just close after 2 sec through the below code

<script type="text/javascript">
    alert('hello');
    setInterval(function(){window.close();},2000);
</script>

I am able to get the hello alert by using WebChromeClient. But the window.close is still not working. Any help would be appreciated.

PS: Here is how i am loading the URL:

WebSettings ws = webView.getSettings();
ws.setJavaScriptEnabled(true);      
ws.setJavaScriptCanOpenWindowsAutomatically(true);
webView.loadUrl("http://192.168.1.137/abc.html");
webView.setWebChromeClient(new WebChromeClient());

Answer 1

Try this :

WebChromeClient webClient = new WebChromeClient(){

    public void onCloseWindow(Window w){
        super.onCloseWindow(w);
        Log.d(TAG, "Window close");
    }
};

Description :

public void onCloseWindow (WebView window)

Notify the host application to close the given WebView and remove it from the view system if necessary. At this point, WebCore has stopped any loading in this window and has removed any cross-scripting ability in javascript.

It's not possible on android version > KITKAT. But I have find solution. If android build version > KITKAT, I have detected message from js on server side in method onConsoleMessage of WebChromeClient class http://developer.android.com/reference/android/webkit/WebChromeClient.html . It works for me.
