Solution 1:

Define the class JavaScriptInterface as inner class of your Activity and store the reference to the WebView as member variable of your Activity.

Because inner classes can access member variables of the class they are defined in, you can change your code to this:

MyWebActivityextendsActivity{
    privateWebView myWebView;
    protectedvoidonCreate(Bundle bundle){
        myWebView = (WebView) findViewById(R.id.webview);
        myWebView.addJavascriptInterface(newJavaScriptInterface(), "Android");
        myWebView.setWebViewClient(newWebViewClient());
        WebSettings webSettings = myWebView.getSettings();
        webSettings.setJavaScriptEnabled(true);
        myWebView.loadUrl("file:///android_asset/html/status01.html");
    }

    privateclassJavaScriptInterface{
        JavaScriptInterface(){
        }
        publicvoidshowOffers() {                
            myWebView.loadUrl("file:///android_asset/html/offers.html");
        }
    }
}
