Ошибка авторизации Google Maps Android v2

Я тестирую пример кода Google на реальном устройстве с 2.3.6. Я подумал, что это может быть проблема с ключом, поэтому я создал другой ключ в другой учетной записи через Google API Console. Все та же проблема «Google Maps Android API - Ошибка авторизации". Вот журнал:

Вот мой манифест:
