Gvr-unity-sdk: Crash after splash [2017.1, GVR 1.7, iOS XCode 8.3.3]

[hamaluik]

Can't get anything to run past the splash screen; it just crashes immediately here:

extern "C"  void GvrAudio_Initialize_m2441973946 (RuntimeObject * __this /* static, unused */, int32_t ___quality0, int32_t ___sampleRate1, int32_t ___numChannels2, int32_t ___framesPerBuffer3, const RuntimeMethod* method)
{
    typedef void (DEFAULT_CALL *PInvokeFunc) (int32_t, int32_t, int32_t, int32_t);

    // Native function invocation
    reinterpret_cast<PInvokeFunc>(Initialize)(___quality0, ___sampleRate1, ___numChannels2, ___framesPerBuffer3); // crashes here with: Thread 1: EXC_BAD_ACCESS (code=1, address=0x9000000000000000)

}

I was able to "fix" this by deleting all Google VR audio stuff (scripts, monobehaviours, and libraries) from the project since I don't need spatial audio anyway.

[VasilOrlinov]

I have similar issues with 2017.2, GVR 1.7. When i try to use GVR spatial audio my Unity project crashes every time.

[CenekStrichel]

Same trouble. It looks that Google VR is absolutely unusable on iOS in current version and with current Unity.

[GoGoBlitz]

Any news? Also have crash immediately after game starts with 2017 unity + gvr 1.7

[diegodias]

Same here. Cant even get the demos to work.

[bunnyhero]

@FuzzyWuzzie thanks for the workaround!

fwiw, this is what i deleted from my project to get it to run without crashing (unsure if i needed to delete all of these or not, but):

• everything in __GoogleVR/Editor/Audio__
• everything in __GoogleVR/Plugins/iOS__
• __GoogleVR/Resources/GvrAudioMixer.mixer__
• everything in __GoogleVR/Scripts/Audio__

[rusmaxham]

A GVR Audio engineer is looking into this now.

[miraclestar]

Same error

[tribuanimal]

Thanks a lot for the solutions. Worked perfectly.

[soundreactor]

same here

[GoGoBlitz]

Well, I recomend to all downgrade to unity 5.5.3 + gvr 1.4 it is only combo which works perfectly without bugs and with good fps.

[zhuyifan2013]

same here!! This issue is very serious !

[biezhihua]

same here!! This issue is very serious !

5.6.3f + gvr1.7.0

Hi,

We have tracked down the issue and will provide a fix in the next SDK update. In the meantime, here is a workaround patch to resolve the issue. To apply the patch on Mac:

1. Open your Unity project, and build a new iOS app as usual - which should generate the corresponding Xcode project.
2. Close the Xcode project (if open already), and make sure you backup its contents, as the scripts will directly modify the library & project files in the Pods folder.
3. Download and copy the attached script into the root folder of the generated Xcode project, i.e., the folder that contains the .xcodeproj file and the Pods folder (will be referred as $XCODE_PROJ_FOLDER below).
4. Open Terminal, then run the following:

cd $XCODE_PROJ_FOLDER
chmod +x iosunityfix.sh
./iosunityfix.sh

1. Once finished, open the Xcode project to build and run the iOS app. The new app should run as expected without any crashes now.

Please note that running this patch is required once, every time you generate a new Xcode project through Unity.

[rusmaxham]

This should be fixed with the most recent versions of Unity 5.6 and 2017.1+ (5.6.4f1 and 2017.1.2f1).

[rusmaxham]

Alternatively, opening a terminal window and running pod update inside the generate Xcode workspace directory, to update to the latest lib GVR, will also fix this issue if you absolutely cannot upgrade your version of Unity.
