Crash on Galaxy S6

January 2, 2018 - 6:28am #1

Hello,

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.

Eyewear type is set to 'None'. I attached the screenshot as requested of my configuration.

This is still unity 2017.2.0f3.

Hello again,

These messages are all related to ODG support, did you accidentally enable digital eyewear settings in the Vuforia Configuration? Can you share a screenshot of this (please block out your license key if you do)?

Thanks,

Vuforia Support

When I make a new project with Unity 2017.2.0f3 everything works, until I add a particle system as a child to the tracker. Then it crashes occasionally (but not always).

Some further digging in the project that always crashes reveals the following lines when Debugging with Proguard:

 :transformClassesWithNewClassShrinkerForRelease

com/vuforia/ar/pl/ODGR7Controller references unknown class: com/osterhoutgroup/api/ext/ExtendDisplay

net/gree/unitywebview/CUnityPlayer.<init>:(Landroid/content/ContextWrapper;)V references unknown class member: com/unity3d/player/UnityPlayer.<init>:(Landroid/content/ContextWrapper;)V

:transformClassesWithNewClassShrinkerForRelease FAILED

BUILD FAILED

 

This also shows when trying to build the apk file via Android Studio instead of unity:

Warning:com.vuforia.ar.pl.ODGR7Controller: can't find referenced class com.osterhoutgroup.api.ext.ExtendDisplay

Warning:net.gree.unitywebview.CUnityPlayer: can't find referenced method 'UnityPlayer(android.content.ContextWrapper)' in program class com.unity3d.player.UnityPlayer

Warning:there were 4 unresolved references to classes or interfaces.

Warning:there were 1 unresolved references to program class members.

Warning:Exception while processing task java.io.IOException: Please correct the above warnings first.

Error:Execution failed for task ':transformClassesAndResourcesWithProguardForRelease'.

> java.io.IOException: Please correct the above warnings first.

 

What is the "osterhoutgroup api"?

Hello LexVR,

Are you able to reproduce this crash in the sample projects? I have not encountered a crash on the Galaxy S6 when using Vuforia with either Unity 2017.2 or 2017.3.

Thanks,

Vuforia Support

*Update*

Further testing points towards 'ImageTargetBehaviour', as soon as I test a build with this script active the crash occurs as described in my previous post.

 

*Update 2*

Disabling extended tracking also "fixes" the crash. Sadly, I need extended tracking for the final release.
