更新到Eclipse开普勒后，我一直无法添加支持库appcompat。我跟着这个说明，我仍然得到错误的进口android.support.v7.app不能在以下行解决

after updating to Eclipse Kepler, I haven't been able to add the support library appcompat. I've followed this instructions and I still get the error The import android.support.v7.app cannot be resolved on the following lines:

import android.support.v7.app.ActionBar;
import android.support.v7.app.ActionBarActivity;

我已经加入了appcompat项目，增加两个罐子到构建路径，选择它们的顺序和导出选项卡上，并在主项目添加库项目。

I have added the appcompat project, added both jars to the Build Path, selected them on the Order and Export tab, and added the library project in the main project.

我复制了V4磁带库可在主项目的libs文件夹，但我不知道自己还能做些什么或检查。有没有人有什么建议？

I copied the v4 library to the libs folder in the main project, but I don't know what else to do or check. Does anyone have any suggestions??

感谢您！

推荐答案

在appcompat_v7添加到您的依存关系，可以肯定的是，库从项目文件夹为空。默认情况下，当你定义你的项目Android的支持 - v4.jar被创建，因此这将导致冲突，当你声明appcompat_v7库的依赖关系。

After you add appcompat_v7 to your dependencies, be sure that the libs folder from your project are empty. By default, an android-support-v4.jar is created when you define your project, so this will cause conflict when you declare appcompat_v7 library as your dependency.

所以，你需要做的第一件事是检查该文件夹 ... / MY_PROJECT /库和无畏地删除文件 Android的支持-v4.jar 。

So, the first thing you need to do is check the folder .../My_Project/libs and fearlessly delete the file android-support-v4.jar.

然后，添加appcompat_v7库项目的依赖关系： 要做到这一点，如果你使用的是Eclipse：

Then, add the appcompat_v7 library as a dependency of your project: To do this, if you are using Eclipse:

如果您使用的是Android的工作室，你可以按照@Joey加西亚的评论中提到的步骤。

If you are using Android Studio, you can follow the steps mentioned in the @Joey Garcia's comment.
