Vuforia SDK Version: 4.0 -Description with steps to reproduce:
I am seeing an occassional error:
Invalid Key used. Please make sure you are using a valid Vuforia App Key
After this error, Vuforia fails to start, and the app is left with a blank screen. This happens perhaps 1 out of 30 times activating Vuforia.
Is the app trying to reach the network to verify the key? Is there any way to prevent this in a production app?
Interestingly if I put my phone in airplane mode, Vuforia starts with no issues.
I am using Vuforia 4.0 in a native iPhone app.
-Development OS (Mac OS X, Windows, Linux): OS X 10.103 -Mobile OS and Version: iOS 8.3 -Mobile Device Manufacturer and Model name: Apple iPhone 6+ -Do the Vuforia Sample Applications show the same behavior?:
Intermittent Invalid Key Error
Seems the issue was caused by setInitParameters being called every time the view loaded (which I believe is what happens in the sample app as well).
