Taming the Monorepo Beast How We Made AndroidX Library Releases
At Scale More Bearable Aurimas Liutikas / AndroidX @ Google @

What is androidx? Collection of widely used open-source libraries Main
Android API surface Broad range of functionality Developed by dozens of separate teams
Early Days Releases (com.android.support)
Early Days Releases Monolith releases a few times a year
21.0.3 21.0.2 21.0.0
Early Days Releases Uniform version with major based on Android
API level 21.0.3 21.0.2 21.0.0 22.2.1 22.2.0 22.1.1 22.1.0 22.0.0 23.4.0 23.3.0 23.2.1 23.2.0 23.1.1 23.1.0 23.0.1 23.0.0
Early Days Releases Eventually added alpha/beta 21.0.3 21.0.2 21.0.0 22.2.1
22.2.0 22.1.1 22.1.0 22.0.0 23.4.0 23.3.0 23.2.1 23.2.0 23.1.1 23.1.0 23.0.1 23.0.0 24.2.1 24.2.0 24.1.1 24.1.0 24.0.0 24.0.0-beta1 24.0.0-alpha2 24.0.0-alpha1 25.4.0 25.3.1 25.3.0 25.2.0 25.1.1 25.1.0 25.0.1 25.0.0 26.1.0 26.0.2 26.0.1 26.0.0 26.0.0-beta2 26.0.0-beta1 26.0.0-alpha1
No Longer Scaling (circa 2018) 60 libraries from ~13 teams
9 pages of release instructions Some libraries were monoliths of their own Bug fix in one library → 59 released with no changes Forced releases to align with Android OS releases

The New Plan Split and restructure libraries • À la

Let’s execute the new plan!
Welp, this is a lot of manual work
Interconnectedness
Interconnectedness
Pinned vs Unpinned api(project(“:foo:foo-bar”)) vs api(“androidx.foo:foo-bar:1.1.0”)
Can we move to self-service?
Optional Release Trains (controlled chaos)
None

androidx-main vs release branches alpha & beta from androidx-main •
regular development rc & stable from androidx-foo-release • cherry-pick only
