I upgrated my Wikitude SDk to the lastest one and now everytime I start the Activity the camera don't work. I mean... I can see the Wikitude logos and even the POI using the sample code. Just the camera don't seems to be working. My device is a MotoDroid 2 GLOBAL with 2.3.3... I tested a old version of my APP and works (the Wikitude SDK version is from February 2013).
