When I try to start the tutorial app "UserDefinedTargets.unity" from "qualcomms vuforia" on my Galaxy Nexus (Android 4.3), the phone crashes and reboots. The logcat shows me the following:
E/IMGSRV ( 3463): :0: Index offset 1698172960 is larger than index buffer size
I am using Unity and the app works fine on my PC with the webcam. I did also some other tutorials with qualcomms vuforia and they all work.
I believe you're probably using the wrong Build Settings. Try changing your
Other Settings>Graphics LeveltoOpenGL ES2.0It shouldn't beAutomatic, orOpenGL ES3.0orOpenGL ES1.xIf this doesn't work, please post your Build Settings window in the question.
