Hello,
Since I've upgraded to SDK 4.2.3 (previously on v4 beta), my app shows a popup "app failed to initizlize", followed by a crash of the app. When relaunching the app, and relaunching the AR, it works this time, this is weird. Please help, this is really blocking for us.
Tested on iPhone 6 iOS 8.0.1
[4.2.3] "app failed to initialize" first time + crash
In case that can help here are the exact traces I'm seeing.
Note that I made a test with a fake key (not valid), and I get the same error, but systematically (when I relaunch the app, it shows the same popup + crash), which makes sense.

Hi,
I've tested on the Sample apps with my keys, and it works perfectly.

Hi
Thank you for your offer, however we have identified the issue and a resolution will be included in an upcoming version of the SDK.
Thanks

Can you provide any guidance on expected release date of the next version, or alternatively if there will be a beta release that includes the fix? We have app ready to be released, this bug is the only thing holding us back -

I've updated to Vuforia 5 and I'm still seeing this problem. Was the fix embedded in the sdk 5?

What iOS device and OS version are you using?
[4.2.3] "app failed to initialize" first time + crash
I'm on iOS 8.3 and iPhone 6.

Did you attempt the workround I mention in this thread? Even a small delay of a few ms between init and loading the datasets should be sufficent.
[4.2.3] "app failed to initialize" first time + crash
Nope I hadn't seen it, thx, I'll try that.
[4.2.3] "app failed to initialize" first time + crash
So I've tried to delay the data loading by 1 second but I still have the "failed to initialize" problem. The SDK tells me it's an invalid key, but the key IS valid. It makes the error only the first time using the app after installing it.

Please try this:
1) Uninstall your app from the device
2) Install your app from scratch
3) Set your device in Airplane mode
If you still get the error at this point, then your key is probably invalid.

Yes I still ge the error. I've used the new key format 4.2. Maybe I should try to generate a new key (if possible)? I'll let you know.

You should be able to go to your project and retreive the key from there and validate it against your local copy. It's possible that your missed some of it when copy/pasting it over.

It seems identical, but I've sent a PM with the line of code I'm using.
[4.2.3] "app failed to initialize" first time + crash
I've ceated another project and another key, and it seems to work now. So I think it was some weird problem with the previous key (the one I've sent you in PM)...

Glad to hear it's working for you, I don't see anything immediatly wrong with the key you sent, but I will investigate today and see if I can find a problem.
