Support for other protocols in Android webview

Question

Hi guys.I've created a web view app, the page that is displayed features market:// links but upon clicking them I get the 404 screen along with the error that the protocol is not supported. I've tried looking through documentation but was unable to find anything relating to this. Any help is much appreciated.

For the links to work you have to have the market app installed on your device/emulator. Also your app need to request a permission to access network.

UPD: as a workaround you can call java code from within the webview, for example if you generate links like this:

<a href="javascript:go('market://your.path.to.market.app')">..</a>

Define a javascript function named go():

<script type="text/javascript">
   function go(link) {
     if (handler) {
           handler.go(link);
         } else {
           document.location = link;
         }
   }
</script>

You then can pass in a handler object into the WebView:

webview.addJavascriptInterface(new Handler() {
        @Override
        public void go(String marketUrl) {
                         //start market intent here
        }
    },  "handler");

Handler interface can be defined as follows:

   public interface Handler{

    public void go(String url);

}
