android WebView: Handle arrow keys in javacript

I have a simple WebView application which I want to control with the keyboard.
Is it possible to catch arrow keys in javascript?

I have tried the following code without any luck:

function handleArrowKeys(evt) {
     console.info('key');                                                                                         
 }
 
 document.onkeyup = handleArrowKeys;
 document.onkedown = handleArrowKeys;
 document.onkepress = handleArrowKeys;
 

javascript is enabled in the webview

WebSettings webSettings = webview.getSettings();
 webSettings.setJavaScriptEnabled(true);
 webSettings.setDomStorageEnabled(true);
