Anyone have any links/resources for Android XML style guides?

No. But you can check in Android Studio,

Editor -> Code Style -> XML

. do

setFrom... -> Predefined Style -> Android

and review what that set the settings to

this repository is style guide for own Google projects, not for recommended or official for Android, so I would use it for own project only if you think it's good, not because Google use it for own projects

Yeah for Kotlin Style I use: https://developer.android.com/kotlin/style-guide for the most part, but they don’t list recommendations for XML that I can find there. So it’s at least a starting point.

I think we are not supposed to be looking at XML as much anymore with the new UI editor and constraintlayouts... however I am still always editing XML because after 8 years of doing that, it's a habit I just will never break. 🙂
