When I am running sample app on version 10.3.2 on Android 5.1 I got this error. (I am running on Vuzix Blade)

E/art: dlopen("/data/app/com.vuforia.engine.native_sample-1/lib/arm/", RTLD_LAZY) failed: dlopen failed: empty/missing DT_HASH in "" (built with --hash-style=gnu?)
D/AndroidRuntime: Shutting down VM

But if I am running on mobile phone with Android 9.0 everything works fine

Thanks. I managed to run SDK version 9 on Vuzix Blade but not 10

Hey there,


That's probably because the Vuzix Blade is not a recommended device. Only the Vuzix 400 is recommended:
