用Eclipse可能不会出现这个问题，我在电脑A上面用Android Studio也没这问题(后来发现是之前可能某些原因已经设置过)，写好模块启动再重新启动手机在XPosed Installer日志中看到java.lang.ClassNotFoundException: Didn't find class 'com.XXX'，看了APK文件确实包类和类名没问题。

再下面有这样一段话，如下：

Please make sure to disable Instant Run (File -> Settings -> Build, Execution, Deployment -> Instant Run), otherwise your classes aren’t included directly in the APK, but loaded via a stub application which Xposed can’t handle.

翻译后大概意思如下：

请确保禁用Instant Run（File -> Settings -> Build, Execution, Deployment -> Instant Run），否则您的类不会直接包含在APK中，而是通过Xposed无法处理的存根应用程序加载。
