Thanks for your reply. I’ve tried restarting, re-downloading, and clearing storage, but I still get this error:

Parse error
There was a problem parsing the package.

I’m using:

Device: Zebra MC40

Android version: 5.1.1 (API 22)

Could you confirm:

1. What is the minimum Android version required for the current QuickBooks Desktop: Inventory app?

2. Is there an older APK compatible with Android 5.1.1?

3. Which specific app version is guaranteed to install on MC40?

Your website lists MC40 as supported, so I’d like to clarify if there’s a specific APK I should use.
