WARNING: There is a known bug in the emulator that causes apps to crash when a native method is called from inside the DOM. Please test on a real device.
This projects is a simple prototype to show how to communicate between Android and
Javascript with a android.webkit.WebView.
The key parts are addJavascriptInterface which creates proxy object in the WebView's window that binds it to the given object.
So calling this method in an Android app:
webview.addJavascriptInterface( anObject, "hybrid_interface" );
Will provide access to the instance anObject via the variable hybrid_interface like so:
<script type="text/javascript">
// someMethod being a method defined in the native app
hybrid_interface.someMethod();
</script>
