Google today announced it has completed the rollout of the new AdMob to over 200 countries and as such the Google Play store will stop accepting apps using the legacy SDK on August 1, 2014. The company will sunset legacy AdMob on August 31, 2014.

Google says the following will occur on September 1 as a result of the sunset:

  • Ads will stop serving to legacy ad units.
  • Legacy house ad campaigns will stop serving.
  • The legacy AdMob UI will be inaccessible.

The company previously said it had “no plans” to stop serving ads, but that has now changed. Android developers are thus being asked to move to Google Play Services as soon as possible (migration guide).
