解决方案 3:

创建一个新项目并将所有内容从这个项目复制到新项目.

解决方案 4:

再次查看您的课程 SocialMainActivity.检查它的活动，您是否在清单文件中将其声明为反对片段.检查这个类的布局xml.Android 布局文本区分大小写，因此请仔细检查所有内容.

View your class SocialMainActivity again. Check that if its activity, did you declared it in your manifest file as oppose to fragment. Check the layout xml of this class. Android layout text is case sensitive so check everything carefully.

多个dex文件定义Lcom/facebook/AccessToken$SerializationProxyV1;

Multiple dex files define Lcom/facebook/AccessToken$SerializationProxyV1;

好吧，这取决于您是仅构建 Facebook SDK，还是将其作为库包含在您自己的 Android 项目中(我想是这种情况).如果您的项目文件夹中有一些 JAR(作为 JAR 添加到您的项目中)，请将它们删除并将它们复制到项目根目录之外的某个位置，然后再次将它们添加为外部 jar.

Well, it depends if you build the Facebook SDK only, or you've included it as Library for your own Android project (I suppose that's the case). If you have some JAR's within your project folder (added as JARs to your project), remove them and copy them somewhere outside your project root, then add them again as the external jars.
