我一直想要在我一直在開發的應用中使用Android Google Map API,並且在實施時遇到問題。我遵循Google Developers提供的教程(https://developers.google.com/maps/documentation/android-api/map-with-marker),當我運行該應用程序時,導致出現此構建錯誤:Build Error。我已經找到了解決這個問題的方法,但一直沒能找到解決方案。Android Google Map V2 API導致構建錯誤

我使用Nexus 5X API 23(在Android 6.0,API 23)模擬器來運行這個。 非常感謝提前
嗨,已經得到了應用,成功地構築,所以向你表示感謝。我遇到了一個新的錯誤,導致身份驗證在服務器上失敗。我是否需要爲此使用另一個API密鑰? – mjonjones
'我遇到了一個導致身份驗證在服務器上失敗的新錯誤。這似乎是另一個與Google地圖無關的問題。即使您沒有獲得api鍵,也沒有在構建gradle中獲得此「GOOGLE_MAPS_API_KEY」值,那麼您將看到一個空白區域而不是地圖。 – Blackkara
