crash in gvr::PlatformInfo::GetApplicationName() when instantiating GVRCardboardView #168

Closed deeje closed 7 years ago

deeje commented 7 years ago

Hi,

I am able to get GVRSDK iOS sample code to run on device, but am hitting a roadblock in my project. After instantiating a GVRCardboardView, it crashes deep inside setVRModeEnabled…

self.cardboardView = [[GVRCardboardView alloc] initWithFrame:stageFrame]; self.cardboardView.context = [[EAGLContext alloc] initWithAPI:kEAGLRenderingAPIOpenGLES2]; self.cardboardView.delegate = self; self.cardboardView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; self.cardboardView.vrModeEnabled = YES;

EXC_BAD_ACCESS (code=1, address=0x0)

Does this ring a bell for anyone?

sanjayc77 commented 7 years ago

Is this in the iOS Simulator or iOS Device?

deeje commented 7 years ago

on an iPhone 6 running iOS 9.3.5

@deeje can you share your source code?

deeje commented 7 years ago

@skycenter :-|

contact me directly?

deeje commented 7 years ago

if I don't set vrModeEnabled = true, I still crash the first time thru calling Render

@deeje just emailed you

sanjayc77 commented 7 years ago

The gvr::PlatformInfo::GetApplicationName() is constructed from: [[[NSBundle mainBundle] objectForInfoDictionaryKey:(NSString *)kCFBundleNameKey] UTF8String].

Can you make sure this returns a bundle name properly?

deeje commented 7 years ago

OK, that fixed it. Any reason why you're using that key rather than kCFBundleDisplayNameKey?
