I just got started on native Android development on Android Studio with Vuforia Android SDK. However, both Android sample apps (VuforiaSamples-6-5-19 and Books-6-5-19) encounter "Failed to initialize Vuforia" error. I've tried changing the targetSdkVersion to targetSdkVersion = 24 in build.gradle and Manifest.xml, but to no avail.
Besides, I've also manually granted the permission to camera access on the device.
So far I have tested with Android 7.0, 6.0, and 5.1 with the exact same error.
Any help would be very much appreciated.
Thanks in advance!
