Hello Alexander and welcome to the Anbox discourse!
Getting right to it:
I’m just stealing mastermind’s response in another thread:
As Solus now supports snaps we can use the anbox snap there as well as anywhere else. Only missing peace is the binder/ashmem kernel driver. Somebody needs to go and package these and then we can provide a package you can install on Solus.
I’m unaware of K+. Does it require root or a version of Android other than Nougat? If not it should be fine, applications are installed via ADB, not the play store, so sideloading isn’t just the best way but the only way
