安卓 2.3.3
我已经阅读了很多关于同一问题的问题，但是我阅读的越多，我就越困惑。所以，我把我的问题放在这里，如果它是重复的，请多多包涵，但我真的想不通。
I have minSdkVersion=8 and targetSdkVersion=17 and
I am targeting devices from Android version 2.2 and above
这是我所做的事情的清单：
- 注册 Google API 控制台 - 获得 API 密钥 - 开启 Google Maps Android API V2。
- 将 google-play-services_lib 导入项目，将其添加为库。
- 由于我的目标是 3.0 以下的版本，我已经阅读了一些我应该使用 ActionbarSherlock 的地方，所以我也将其导入并添加为库。
请查看下面的屏幕截图和代码，让我知道我哪里出错了。我已经读过，我需要在 XML 中使用“SupportMapFragment”并在类文件中使用“extend FragmentActivity”，但我没有让它正常工作。

Marker hacc = map.addMarker(new MarkerOptions().position(hacc_position)

// Move the camera instantly to hacc with a zoom of 15.
map.moveCamera(CameraUpdateFactory.newLatLngZoom(hacc_position, 15));
// Zoom in, animating the camera.
map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);
}
我不确定如何解决这个问题。我必须支持 2.2 及更高版本的设备，这是强制性的。
有人可以帮忙吗。
我无法执行该项目，因为我有错误
map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
.getMap();
如果您需要任何信息，请告诉我。

谢谢您的帮助！！！
根据 CommonsWare 的建议，我已经导入了包并且错误消失了。当我运行应用程序时，我得到一个 ClassNotFoundException。请查看 logcat 跟踪。
