title: Android WebView/WebViewClient crash using emulator after browsing using loadUrl
body: <p>I'm using WebViewClient to browse urls using the emulator. after a while (cannot tell exactly the cause), the pages cannot be loaded anymore or they view takes forever, for the same sites as before that were very fast.
  Usually i see under onReceivedError the error -2 (WebViewClient.ERROR_HOST_LOOKUP)
  Any help/reference would be appreciated. </p>
  
  <p>Thanks!</p>
