Rather than pushing, you could try pulling:
webView.addJavascriptInterface("paraz", new TheMiguelParazObject());
webView.loadUrl("file:///android_asset/page.html");
TheMiguelParazObject has some method (e.g., initScript()) that returns
your desired Javascript ("var x=1;");
Your file has a <script> element up front that calls eval() on the
result of paraz.initScript().
