Android custom Event to Javascript EventListener

Is it possible to create in Android event, which sends data to Havascript EventListener in WebView?

For example:
In background, I start thread what search updates on server. When updates was found I send event to update data on user page. And I don't want reload view.

Solution

  • Currently the only way I found out was using JavaScript injection:

    mWebView.loadUrl("javascript:helloWorld(\"hi\");"); //or postUrl if using HTTP POST

    This will cause the function helloWorld defined in the JavaScript of the webpage to be called with parameter value hi.
