Google Play Target API Level: 2026 Deadline
Google Play target API level rules for 2026: what the August 31 deadline blocks, what breaks when you move to API 36, and how extensions work.

The store deadline that just moved, the release that keeps failing review, the codebase a previous developer left behind without documentation: that is the territory these articles cover. RapidLabs publishes what it learns doing that work, with the version numbers, console screens and dates named so you can check any of it yourself.
Most writing about mobile apps is aimed at somebody still deciding whether to build one. These articles assume you already did, that the app is in front of real users, and that your problem now is keeping it there. That changes what is worth saying. You don't need another argument for why maintenance matters, you need to know which Play Console screen reports what your uploaded build actually targets, and how much time a policy extension genuinely buys you.
Every deadline, version number and store rule here was checked against Apple's or Google's own documentation on the day the piece was written, and each article carries that date at the top. Store policy moves fast enough that anything more than a few months old should be treated as a starting point rather than the current rule, so check the primary source before you plan a release around a number you read on someone's blog, including this one.
They're written by Andrey Gordeev, who runs RapidLabs and works inside other people's iOS and Android codebases for a living. That is the bias worth knowing about before you read anything below: the examples come from apps that were already late, already broken, or already inherited, because that is what lands on this desk.
The three groups below are the problems clients actually arrive with, in the order they tend to become urgent. If you already know which one you are in, skip straight to it.
Store rules are the one part of running an app where somebody else sets the deadline and you get no vote on it. These pieces cover what Apple and Google currently require, what they block when you miss a date, and what the console is really telling you when a submission comes back rejected.

Plenty of what these articles describe is work you can do yourself with a free afternoon and the right console screen open. The pages below are for the situations where that stops being true, and each one says plainly what it covers and where its pricing starts.
Monthly senior capacity for an app that is already live: fixes, SDK and OS updates, store compliance, and a release rhythm you can plan around.
See the service →Picking up a codebase somebody else wrote, getting a signed build out of it, and moving the app and its store accounts off the previous developer.
See the service →Crash triage and release-blocker work for an app that ships late, breaks on release, or keeps coming back from store review.
