为Android的Facebook示例应用程序无法正常工作 [英] Facebook sample apps for Android not working

问题描述

只是试用一下Facebook的SDK为Android跟着入门指南。完成所有步骤，但是当我导入示例项目偏食，编译失败，出现以下错误：

was just trying out the Facebook SDK for android followed the getting started guide. Completed all the steps, but when I imported the sample projects to eclipse, the compilation failed with the following error:

片段不能被解析为一个类型ProfilePictureSampleFragment.java

Fragment cannot be resolved to a type ProfilePictureSampleFragment.java

然后我加入supportLibrary（从AndroidSDK /演员/安卓/支持/ Android的支持 - v4.jar）作为外部罐子。编译错误不再出现，但是当我尝试运行应用程序，它扔我此异常：

I then added the supportLibrary (from AndroidSDK/extras/android/support/android-support-v4.jar)as an external jar. The compilation error was no longer there, but when I try to run the app, its throwing me this exception:

所有其他PARAMS为默认。我使用的是Mac OS和已登记的关键哈希到我的开发设置。我试图运行ProfilePictureSample应用程序。

All other params are default. I am using a MAC OS and have registered the key hash to my developer settings. I am trying to run the ProfilePictureSample app.

推荐答案

哦..只是得到它的工作。刚走到Java构建路径，并在那里检查Android支持-v4.jar。工作:)

oh.. just got it working. Just went to Java build path and checked android-support-v4.jar in there. Worked :)
