Answer 1

Yes you have the syntax error. If you want to get your Javascript errors and printing statements in your logcat you must implement the onConsoleMessage(ConsoleMessage cm) method in your WebChromeClient. It gives the complete stack traces like Web console(Inspect element). Here is the method.

public boolean onConsoleMessage(ConsoleMessage cm) 
    {
        Log.d("Message", cm.message() + " -- From line "
                             + cm.lineNumber() + " of "
                             + cm.sourceId() );
        return true;
    }

After implementation you will get your Javascript errors and print statements (console.log) on your logcat.
