Desperate Help Needed on media recorder
<p>I'm trying to create a simple camcorder application using mediarecorder and have spent 12+ hours trying to get it to work... its been frustrating as all hell. I've searched all over for the solution and attempted to use multiple pieces of sample code but still can't get it to work. The program keeps crashing and I get errors when I call prepare on the mediarecorder. </p>

<p>Layout Below
