I downloaded the code from their Github and imported into Android SDK, but it shows error at the lines
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.NavUtils;
在多个文件。但是，如果我检查了Android SDK管理器中， Android的支持库还有 Android的支持库在Extras文件夹同时安装。我还可以看到支持文件夹和它的内容在 SDK_INSTALL \ SDK \演员\机器人\支持目录。它也有其中还包含了 Android的支持 - v4.jar 和的src 文件夹中的文件夹V4。那么为什么它仍然显示错误，我怎么解决它，我怎么拿到样品code运行？样品code是一个RSS阅读器应用程序，如果是相关的。
in multiple files. However if I check the Android SDK Manager, the Android Support Library as well as the Android Support Repository in the Extras folder are both installed. I can also see the support folder and it's contents in the SDK_INSTALL\sdk\extras\android\support directory. It also has the v4 folder which also contains the android-support-v4.jar and the src folder. THen why is it still showing the error, how do I resolve it and how do I get that sample code running? THe sample code is for an RSS reader app, if that's relevant.
