Android face detection MaxNumDetectedFaces
<p>So I just upgraded my tablet (original asus transformer) to android version 4.0.3 to build a app using face detection. But every time i launch it and try to start face detection i get this error in logcat:</p>

<pre><code>E/AndroidRuntime(1755): java.lang.IllegalArgumentException: invalid face detection type=0
</code></pre>

<p>I read in the documents it means 0 faces are able to be detected or supported but does this mean my device cant detect faces at all or is it something i can change? Also its using the back camera, would changing it to the other camera change anything? I've been trying to do that but i cant figure out how, the project im trying to run can be found here:</p>
