Android app Blinky - How does databinding in the Scanner Activity work?

[mbustin-eastman]

In the scanner activity of the Blinky android app, there is the following import:

import com.switchmaterials.android.nordicble.databinding.ActivityScannerBinding;

It is then used to create an ActivityScannerBinding object called binding

private ActivityScannerBinding binding;

The binding object is then used to control the UI, but how does this import work? How would I go recreating this binding in my own application? I can't find anything called "databinding" in the no.nordicsemi.android.blinky package directory tree, and I'm not sure how to research this detail online.

Thanks,

Mark

Hi Mark,

Could this be the same as Issue 69 in the nRFBlinky github repo?

Yup, that's my exact question! My blinky app will build just fine; however, if I take this approach in a separate app then I'm getting the same error as the issue creator.

The suggested fix in the github by philips77 seems to be a common fix for this type of problem; however, I found my fix in this stack overflow question here.
