錯誤可能是因爲com.google.android.gms.maps.MapFragment包在main.xml中的。我有com.google.android.gms封裝在我的DUT中，但無法找到com.google.android.gms.maps.MapFragment。我怎麼知道這個軟件包是否在我的DUT中，以及錯誤的解決方案是什麼。

MapFragment是google-play-services庫的一部分。要使用它，你需要將google-play-services導入到workspace，然後從你的項目中引用它，你可以蘆葦它是如何在這篇博客我寫的first 3 steps完成：

我成功了一點，但現在eclipse正在拋出一個新的錯誤 - 「無法連接到谷歌服務器」。此外，我能夠在應用中看到放大/縮小選項，但地圖圖塊不會顯示在屏幕上。任何關於這個的想法！ – 2013-04-12 04:54:15

現在，我可以在我的應用程序中看到地圖。我在生成API密鑰時使用了錯誤的軟件包。 – 2013-04-15 09:02:49

@YugalKothari，很好，你有一個很好的代碼：） – 2013-04-15 10:40:23
