I have an ASUS Eee Tab (Transformer Prime TF201 Android v4.1.1). I was reading the API on Geofencing and downloaded the sample app here below on to my device => http://developer.android.com/training/location/geofencing.html. But it terminates when i open it.

I have set the target sdk = 16 in the AndroidManifest.xml file

  1. 创建“libs”文件夹
  2. 放入 android-support-v4.jar 和 google-play-services.jar jar 文件

并运行示例项目它就像一个魅力。你可以从“ adt-bundle-windows-x86\sdk\extras\google\google_play_services\libproject\google-play-services_lib\libs ”找到 google-play-services_lib 我认为你已经使用了 Goolge 包来删除这个包。删除您为此项目创建的所有参考。清理您的示例项目并享受。 我的示例项目的结构和 输出

根据官方 Android 团队创建和监控地理围栏的说法，您应该设置在 Android 模拟器上运行的 Google Play 服务 SDK，其 AVD 运行基于 Android 4.2.2 或更高版本的 Google API 平台。

在 geofences trianing 链接中说：

Note: To make your app compatible with platform version 1.6 and later, the activity that displays the DialogFragment must subclass FragmentActivity instead of Activity. Using FragmentActivity also allows you to call getSupportFragmentManager() to display the DialogFragment.

我在启动Activitywhich extends时遇到了同样的问题MapActivity。花了一些时间和研究来找到答案。在标签下添加uses-librarymanifest.xml为我解决了这个问题：application

<uses-library android:name="com.google.android.maps" />
