android WebView goBackOrForward() vs goBack()
<p>I have a WebView and i using WebView.goBack() when tap back button and i using WebView.goBackOrForward(x) in another place.</p>

<p>My question is that why WebView.goBackOrForward(x) loads visited web page again from internet but WebView.goBack() does not load visited web page again and shows previous web page quickly?</p>
