Google released Android Google Mobile Ads SDK 25.0.0, a major update introducing new banner sizing logic, breaking API changes, and important deprecations.
Key updates:
• New Large Anchored Adaptive Banner sizes
A new API (getLargeAnchoredAdaptiveBannerAdSize) replaces the previous anchored adaptive banner sizing. Larger banner formats are designed to improve engagement and increase publisher revenue potential. Older anchored adaptive banner APIs are now deprecated.
• Breaking changes for developers
Several deprecated mediation and custom event APIs have been removed. Developers must migrate to updated classes and callbacks using AdError handling and updated configuration methods to maintain compatibility.
• SDK deprecations and sunset timeline
SDK versions 23.0.0–23.6.0 are now deprecated, while versions 22.x will stop working after June 30, 2026. Apps must upgrade to avoid ad serving disruptions.
What it means:
This is primarily a developer and publisher update. App publishers should upgrade quickly to maintain ad delivery, ensure mediation compatibility, and benefit from improved banner performance on modern mobile devices.
