Cocos2d-x 4.0 AdMob Extension + Android/iOS Sample App + Publisher Package

Description: We need a Cocos2d-x 4.0 (CMake) developer — not Cocos Creator — to build an AdMob mediation adapter package with a demo app and publisher-ready zip. Publishers run a Node.js CLI to inject our custom AdMob adapter into proj.android / proj.ios_mac. The extension only adds the native adapter dependency. It does not show ads, add Load/Show APIs, App ID, or GMA SDK. Deliverables: 1. ads_admob_cocos2dx (build first) Node CLI: node inject.js --project /path/to/game [--platform android|ios|all] Android: Gradle adapter dependency + mavenCentral() if missing iOS: merge adapter pod into existing Podfile (don’t replace it) Idempotent, clear errors if platform folder missing 2. cocos2dx-4.0-admob-sample (build second) Home + 5 screens: Banner, Native, Interstitial, Rewarded, App Open Each screen: Back, Load, Show (Banner/Native have ad area) GMA in sample only — Android JNI + iOS ObjC++ Log all callbacks to console with prefix COCOS_SAMPLE_APP (no on-screen log) 3. Publisher package Release zip ads_admob_cocos2dx-v semver .zip + README (unzip, inject, pod install, build, verify) Tested on clean Cocos2d-x 4.0 project — Android + iOS Must have: 3+ yrs Cocos2d-x / native mobile dev AdMob on both Android (Gradle, JNI) and iOS (CocoaPods, ObjC++) Node.js CLI / build injection experience Not a fit: Cocos Creator only, single-platform, or scope changes Process: Fixed BRD provided. UI and Load/Show rules are strict no extra screens or buttons. Complete after Dev + QA pass on Android and iOS. Apply with: Cocos2d-x + AdMob portfolio (both platforms), timeline, and fixed-price quote.
