google-mobile-ads-rewarded

This skill guides an AI agent through implementing Google Mobile Ads (GMA) SDK rewarded ads — full-screen ads that grant in-app rewards after a user explicitly opts in — in Android, iOS, or Unity applications. It solves the problem of correctly loading rewarded ads, wiring event callbacks, gating display behind explicit user opt-in, and handling the reward callback and threading rules on each platform.

The SKILL.md defines an ordered workflow: load the ad, register for ad event callbacks, add a UI element (such as a button) that lets the user opt in to view the ad, show the ad, and verify the implementation. Platform detail lives in android-rewarded.md, ios-rewarded.md, and unity-rewarded.md, which supply the required imports, method signatures (AdRequest.Builder, RewardedAd.load with AdLoadCallback, show() requiring an OnUserEarnedRewardListener), and per-platform test ad unit IDs. A recurring mandatory rule is that rewarded ads must never be shown automatically — an interactive UI element is required — and that GMA callbacks run on a background thread so UI operations must be scheduled on the main thread (via runOnUiThread, Dispatchers.Main, or MobileAdsEventExecutor.ExecuteInUpdate on Unity). The Unity guide also shows checking CanShowAd() with a null check before displaying.

Target users are mobile developers and AI agents adding opt-in reward mechanics — such as granting coins or lives for watching an ad — to Android, iOS, or Unity apps. The skill is scoped to standard rewarded ads and excludes 'rewarded interstitial' ads.
