How to communicate between WebView & JavaScript?

Issue

I am developing native application. My application have a WebView. I want to log this WebView's component's every action. Which button clicked, which image dragged. After that, I will log those things, I want to store in SQLite.

So, I googled and find WebAppInterface which communicates Java & JavaScript. But this communication isn't enough. I can't send database from WebAppInterface class.

I want to ask this question actually (minute 46:00).

Is it possible? Or, another solution?

You should add javascript interface to your webView like that:

webView.addJavascriptInterface(new JavascriptInterface(this), "AndroidFunction");

You should create interface class:

public class JavascriptInterface{
Context mContext;

    JavascriptInterface(Context c) {
        mContext = c;
    }

    public void save(String action){
        // save to database
    }
}

On the website you should call:

AndroidFunction.save("actionName");
