how to call javascript from java

[sarad mohanan]

I am new to cordova. I have created a webview from where i able to call java from by javascript. I am extending the app now. I want to dynamically update the webview and render the new feed whenever there is one available in database. In fact I want to use database listener so when ever there is a change in database it will fire a javascript call and the new feed will be rendered. how do i achieve this. I went through cordova plugin and understood that it is used for java call from javascript(correct me if I am wrong).

You can do it with the webview.loadUrl("javascriptString");
I think there is another way, but I don't remember right now

I have used like this in my plugin - 

  webView.loadUrl("javascript:cordova.fireDocumentEvent('myeventname');
