I need the necessary code to write to my MainActivity.java, to avoid the error ERR_UNKNOWN_URL_SCHEME ,
I am creating an android application with Chrome webview client that loads an .html file that contains buttons href="tel:" mailto: etc ... but I do not want to use phonegap nor cordova nor any plugin, if someone knows how to solve it please indicate your answer, I have a bit of code that does not solve anything, but maybe it helps, I'll attach it below.
that's how I have the html and javascript
this.myBrowser.loadUrl("file:///android_asset/index.html");

// TODO Auto-generated method stub
if(url != null && url.startsWith("whatsapp://"))

return true;
}else
{
return false;
}
}

Intent emailIntent = new Intent(Intent.ACTION_SENDTO);

emailIntent.setData(Uri.parse(url));
// 'FLAG_ACTIVITY_NEW_TASK' opens the email program in a new task instead as part of this application.
emailIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
