在Android模擬器上運行Geofence應用

Question

有沒有一種方法可以運行Android模擬器上提供的示例Geofence應用程序： http : //developer.android.com/training/location/geofencing.html

該應用程序在啟動時關閉，我在LogCat上收到以下錯誤消息：

似乎找不到您的MainActivity。 也許您的Manifest.xml文件中沒有提到它？

除此之外，讓地理圍欄應用程序在模擬器中運行實際上沒有任何意義。 Android的Geofencing API很大程度上基於網絡定位，並且模擬器僅支持GPS。 因此，即使您可以使應用程序在模擬器上運行，創建地理圍欄也會因其他異常而失敗。
