刚刚接触Xposed，感觉牛掰得不要不要得，简单写个demo后发现无效果，查看Xposed提示日志如下：

从日志中可以看出，原因如下：
Failed to load class com.xposeddemo.xposed.XposedInit
首先再LZ检查确认前期配置无误时，只能耐心用三流得英文水准结合二流得翻译工具去理解一流得Fuck English。。。
官方API地址：
https://github.com/rovo89/XposedBridge/wiki/Using-the-Xposed-Framework-API
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。
