Started playing with the camera and I came across this tutorial http://www.tutorialspoint.com/android/android_camera.htm
I just copy and pasted the code from the first tutorial and tried to run it on my Nexus 7 (KitKat) and HTC desire S.
On both systems it crashes immediately....
Since I am new to android and I don't understand what the problem is.
I am posting the LogCat.
Sorry that it's so big.
