How to load my JavaScript code in WebView?

Question

I am trying to use my JavaScript code in Android WebView. First I enable Javascript and load html with my script.

webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("file:///android_asset/javascript.html");   
webView.getSettings().setUseWideViewPort(true);
webView.getSettings().setLoadWithOverviewMode(true);
webView.getSettings().setBuiltInZoomControls(true);

After that I load some web page in WebView.

webView.loadUrl("http://www.example.com");

When I try to do this

webView.evaluateJavascript("myJavascript();", null);

I get message :

[INFO:CONSOLE(1)] "Uncaught ReferenceError: myJavascript is not defined"

Function myJavascript is defined in "javascript.html" in assets. I suppose that is because after load some page JavaScript is no more in WebView. Can I have loaded in same time HTML with my JavaScriptcode and some web page? I want to define JavaScript in HTML.

setDomStorageEnabled(true);

webView.loadUrl("http://www.example.com");
