I have solved my problem.
My mistake was that i called world.getCamera(); but getCamera return the Camera object so i got an empty Camera object.

Hi,

i have made an app like HelloWorldAe.
When i compile this app it is ok but at runtime there is an error by moveCamera, lookAt or setPosition method.
If i comment out the lines with moveCamera, lookAt and setPosition then it's fine.
I have tested the HelloWorldAe example too and there is the same error.

Currently i'm at work. I post the error log when i get home.

On line 83 is cam.moveCamera(Camera.CAMERA_MOVEOUT, 1.0f);
I have testet the app on the emulator and on HTC Desire.
Any idea how i can solve this problem?
