looks wrong to me. You should add this artifact with the SDK Managaer.
Most probably you are using AndroidX so you should add the AndroidX Artifact instead of the deprecated support Artifact.
Looks like you are using an old library that referenced this resource in a non-standard way. Find the library and remove it. There are probably better options now.
Seems like the error causing agent is in Firebase Realtime database by @DonManfred
Unfortunately, there's no recent version of this lib, and all the rest API classes have no realtime listening feature.
What version does this lib depend on of constraint-layout.aar ?
I tried placing all these versions in additional lib and jetifying them:
I don´t think the library depends on it.
Maybe in the example i was using it because of the Firebase layout loading from json. I can only remember darkly...
For the FBRTDB itself you don´t need any constraint-layout.
