Android Web-view Error I/chromium: [INFO:CONSOLE(1)] "Uncaught ReferenceError:

Add this script in Web-service at your Parent Menu which has your iframe or iframes

<script>
function actfromAnd(msg){
window.frames['yourExactframe'].document.getElementById("brcd").value = msg;
}
</script>

If you are using same in more than one frame then declare your frame name globally

I tried your Code Working Fine... In my example Frame Hope It works fine for you

Nice question....

• You should execute the javascript when the page is loaded

  mWebView.setWebViewClient(new WebViewClient() { @Override public void onPageFinished(WebView view, String url) { webview.loadUrl("javascript:myFunction()"); } });

• The code will be executed and will find your javascript function. The way you are doing now does not wait.
