webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setDomStorageEnabled(true);
webView.loadUrl("http://example.com/");
webView.setWebViewClient(new WebViewClient(){
@Override
public void onPageFinished(WebView view, String url) {
    super.onPageFinished(view, url);

    final String password = "password";
    final String username = "username";
    final String answer = 5;

    final String js = "javascript:" +
            "document.getElementById('password').value = '" + password + "';"  +
            "document.getElementById('username').value = '" + username + "';"  +
            "var ans = document.getElementsByName('answer');"                  +
            "ans[0].value = '" + answer + "';"                                 +
            "document.getElementById('fl').click()";

    if (Build.VERSION.SDK_INT >= 19) {
        view.evaluateJavascript(js, new ValueCallback() {
            @Override
            public void onReceiveValue(String s) {

            }
        });
    } else {
        view.loadUrl(js);
    }
}

});
