Google Mobile Ads in Libgdx (replaces deprecated AdMob) - garsue/libgdx GitHub Wiki
If you use AdMob in your LibGdx apps, and have not updated recently, you should consider doing so soon!
Google says:
Android (6.4.1 and earlier SDKs) Deprecated. On August 1, 2014, Google Play will stop accepting new or updated apps that use the old standalone Google Mobile Ads SDK v6.4.1 or lower. You must upgrade to the Google Play version of the Mobile Ads SDK by then.
