我没有显示任何图钉；我只是想显示一张地图，但是当我尝试开始一项活动时，它会被强制关闭并给出异常：

显示某种类型的片段类错误或二进制错误

清单文件是：

您的 mainfest 显示 minSDK=8，这意味着您必须使用 SupportMapFragment 而不是 Fragment：

SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);

请参阅下面的我的博客文章。我试图总结所有关于使用 Google Maps API V2 for Android 构建应用程序所需的内容。

  1. Maps API V2 问题的解决方案（使用 google_play_services_lib）。
  2. 使用 Maps API V2 for minSDK=8 (Android 2.2 Froyo) 创建一个 Android 应用程序。
  3. 使用 Maps API V2 for minSDK=11 (Android 3.0 HoneyComb) 创建一个 Android 应用程序。

要添加SupportMapFragment到您的项目中，您需要添加google-support-v4库和 Google 地图库。

检查 Stack Overflow 问题Google Maps Fragment doesn't load。
