I am experiencing app crashes on Android and would appreciate any help to solve it. I have updated my system to use Unity 5.1.3f1, Vuforia 5.0.5, java 1.8, and the latest android sdk. I created a new Unity project and imported Vuforia and the Vuforia core samples. On Android 5, everything is great. On Android 4.4.2 devices, it ends abruptly and shows a segmentation fault error on adb. I'm trying to figure out what's wrong. The adb log shows certain things that might be relevant:
Vuforia initialization successful
Found Trackable named stones with id 1 (similar lines for chips and tarmac)
Trackable chips lost (similar lines for stones and tarmac)
Requested Focus mode FOCUS_MODE_CONTINUOUSAUTO successfully.
then this: signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 00000000
using armv7, openGLES2, rendering path forward
I've tried various minimum api levels, no difference
I have no idea what's going on.
