Android地圖擴展程序出錯了

Question

好吧，我已經搜索並搜索了，我正在獲取此示例項目的最後一道關卡，但現在它仍然無法在我的手機上啓動（Galaxy S4），當我試圖執行android-maps-extensions 2.0（我有加載到標記添加到地圖，但需要它們動態）

我有庫的所有設置和工作，因爲他們應該，但每當我將MapFragment代碼更改爲SupportMapFragment應用程序崩潰並且不會打開。如果我離開的一切，是我的電話罰款的應用程序加載

logcat的

我在做什麼錯？我正在絞盡腦汁想要解決這個問題。我有這麼多的標記添加到地圖我需要的地圖擴展

的集羣能力謝謝

我已經想通了。我沒有在佈局文件中導入com.androidmapsextensions.SupportMapFragment，我導入了com.google.android.gms.maps.SupportMapFragment，因此地圖未加載。
