Google on July 6, 2026 designated its rewritten Google Mobile Ads Next-Gen SDK as the preferred software development kit for Android, a decision that simultaneously classifies the SDK that had powered in-app advertising integrations for years as legacy technology. The announcement, posted to the Google Ads Developer Blog by Natalia Vargas-Caba of Mobile Ads Developer Relations, applies to developers building for both Google AdMob and Google Ad Manager.
The change is more than a naming update. It starts a formal deprecation clock for the older SDK, one that Google says mirrors the retirement schedules it has applied to previous major SDK versions. According to the announcement, GMA Next-Gen SDK represents a significant rewrite of the Google Mobile Ads SDK, built to improve speed, stability, and the day-to-day experience of building against it. Google frames the older codebase, by contrast, as something developers should now plan to leave behind.
What the deprecation schedule actually requires
The blog post lays out a three-stage timeline that governs how long apps built on Google Mobile Ads SDK (legacy) version 25.x.x can keep functioning. Each stage carries a distinct technical consequence, and the gap between them gives development teams a fixed, published runway rather than an open-ended warning.
The first stage, labeled supported, runs through July 1, 2026. During this period, ads continue to serve normally, and Google still provides technical support for developers who run into integration problems, reachable through a dedicated contact form.
The second stage, labeled deprecated, begins June 30, 2027. Ads still serve during this phase. What disappears is technical support: developers troubleshooting issues with the legacy SDK after that date will not have a Google support channel to turn to, even though their apps keep running.
The third and final stage, labeled sunset, arrives June 30, 2028. According to the announcement, ads are at risk of not serving…
