The main problem is to access to the public attributes methods of the instance object from javascript, because I try to implement the W3C standard. This standard explicit force the access to the data through public attributes ( no from public methods). The above class hierarchy that i shows you is not casual, the W3C constrained it, and if i want to be according with that standard i need to implement in this way. My question is if i can do it using webview interface (addJavascriptInterface), or i need to do something more to adapt it to provide support to this standard in android. Can anybody give me some ideas to implement this feature in android, any ideas are welcome. best regards.
