Android hardware acceleration webview crash
<p>Through the android market, for my app users are reporting a significant number of UnsupportedOperation Exceptions. The stack trace points to a drawPicture() call made from inside webview codes. I am indeed using webviews in my app.</p>

<p>I know that drawPicture() is not supported when HWA is turned on, but in this case the call is coming from inside a webview. Are there special steps I need to take to ensure the webview will not use this method?</p>

<p>Unfortunately I have not been able to reproduce the issue, but it is definitely being seen by users.</p>

<p>The stack trace:</p>
