Question

So if a logout button is clicked on the webview (which is a spring app), the page should get back to the android login page. is this possible? the code is on a .js file. i want it like

        if(btnlogout.clicked) then 
            go to Intent intent = new Intent(menuScreenActivity.this,
                        LoginActivity.class);

Hmmm maybe yo need to integrate your webview and your java code as you can see here:

http://developer.android.com/guide/webapps/webview.html

Binding JavaScript code to Android code

WebView myWebView = (WebView) findViewById(R.id.webview); 
WebSettings webSettings = myWebView.getSettings(); 
webSettings.setJavaScriptEnabled(true);
webView.addJavascriptInterface(new JavaScriptInterface(this), "Android");

So, you are Telling here that your webview can use run javascript and will be able to access to your java code available at JavaScriptInterface class and its public methods on using js like this way:

<input type="button" value="Say hello" onClick="showAndroidToast('Hello Android!')" />

<script type="text/javascript">
    function showAndroidToast(toast) {
        Android.showToast(toast);
    }
</script>

The line on javascript is Android.showToast(toast); and Android is the name you choosed here webView.addJavascriptInterface(new JavaScriptInterface(this), “Android”);

showToast is a public method on JavaScriptInterface CLASS containing what ever you need, in this case:

**public void showToast(String toast) {
    Toast.makeText(mContext, toast, Toast.LENGTH_SHORT).show();
}**

just copied all this from that link… i think this answer your question, you can create your method called Logout that do the necesary stuff like:

Intent intent = new Intent(menuScreenActivity.this,LoginActivity.class);
