谷歌地圖不顯示任何東西在地圖中

我在活動中顯示地圖...但是當我在設備上運行應用程序時它不顯示任何東西，它只顯示白色屏幕並放大縮小選項... MAP關鍵是正確的..感謝..谷歌地圖不顯示任何東西在地圖中

你有沒有在你的android地圖項目中引用谷歌播放服務庫？並啓用https://code.google.com/apis/console – Raghunandan

'「MAP key is right」映射API v2然後再次卸載並安裝應用程序。 –

yap我引用了Android地圖項目中的Google Play服務庫。 Api鍵是釋放，我用這個項目創建（https://code.google.com/apis/console）..感謝您的重播.. –
