My app is crashing on the Galaxy S6 with Android 7 (I can't test on another device). I attached a few log files with the crashes.
The app was made with Unity 2017.2.0f3. I already tried upgrading to Unity 2017.3.0f3, the crash remains the same.
From what I can decipher from the Debug/Error log the crash has something to do with the following methods:
(from Unity Debug log) Vuforia.VuforiaARController:UpdateState(Boolean, Boolean)
(from libVuforia.so) Vuforia::setInitParameters(_jobject*, int, char const*)
The crash happens often a few seconds after start, but it can also take more then a minute. On a few occasions the crash doesn't happen at all.
Everything works fine when I run it in the unity editor.
