Google Mobile Ads (GMA) Next-Gen SDK is now the preferred SDK for Android development with Google AdMob and Google Ad Manager. GMA Next-Gen SDK is a significant rewrite of Google Mobile Ads SDK that improves speed, stability, and the developer experience. Google Mobile Ads SDK for Android is now legacy.


We invite you to integrate GMA Next-Gen SDK and discover the performance and stability enhancements it can bring to your Android applications. To get started today, migrate to GMA Next-Gen SDK in [AdMob](https://developers.google.com/admob/android/next-gen/migration.md.txt?utm_source=googleblog-adsdevs&utm_medium=blog&utm_campaign=adr-gmanextgensdk-ga&utm_content=nextgen-preferred) and [Ad Manager](https://developers.google.com/ad-manager/mobile-ads-sdk/android/next-gen/migration.md.txt?utm_source=googleblog-adsdevs&utm_medium=blog&utm_campaign=adr-gmanextgensdk-ga&utm_content=nextgen-preferred).
