MapActivity заводская ошибка клиента android

Question

Я создал приложение для Android.он был в состоянии выполнить это должным образом, но теперь, когда я выполняю это, говорит Couldn't get connection factory client.я могу видеть карту также, поэтому нет точки неправильного API-ключа.

все работает, но не входит внутрь onLocationChanged(Location location)
