Two panels comparing what the Android Publisher API accepts before and after an app has been published once. Before: uploads, listings, images and draft releases all succeed, but a completed release returns 400 and country availability reads as zero countries. After: completed releases, staged rollouts and halts all succeed.

The Play Publisher API cannot make an app’s first release live — only draft releases exist until you publish once by hand

Uploading, listings and images all work on a never-published app. Setting a release to completed returns 400 until someone presses Publish in the Console.

One primitive list, rendered by Pillow and emitted as VectorDrawable paths, keeps the Play icon and the adaptive launcher icon identical

Store icon and launcher icon drifted apart because two scripts drew them. One geometry, two renderers, and a 0.48 viewport ratio fixed it.

Two processes open edits A then B on one app; the server drops A when B is created, so process 1's later read of A gets HTTP 400 'This Edit has been deleted' while process 2's read of B returns 200.

Google Play’s edits.insert silently deletes the app’s previous open edit — two parallel API scripts fail with ‘This Edit has been deleted’

Two Play API clients on one app: the second edits.insert discards the first edit and every call on it returns HTTP 400. Serialize per package.
