# Unity Ads SDK integration guide for Android developers

> Integrate Unity Ads into your Android app. Follow step-by-step guides to install the SDK, initialize it with your Game ID, and implement interstitial, rewarded, and banner ads with Java.

The following topics detail how to implement Unity Ads in your Android project.

> **Important:**
>
> If you serve Unity Ads through a mediation partner, such as Unity LevelPlay, Google AdMob, or AppLovin MAX, follow your mediation partner's Unity Ads adapter guide instead of this direct-integration guide. In most cases, the mediation SDK initializes the Unity Ads adapter for you, so calling Unity Ads initialization from your own code risks a duplicate initialization. Install and initialize the Unity Ads SDK yourself only when your mediation partner's adapter documentation tells you to, such as on an open-source adapter path. For more information, refer to [Implement Unity Ads in a mediation stack](/grow/ads/mediation/unity-ads-in-mediation.md.md).

> **Important:**
>
> You must configure user consent before or during SDK initialization. Serving ads without consent configuration may violate privacy regulations in some regions.
