在修改的方法中引用已知类，出现ClassNotFoundException

[670832188]

在修改的方法中引用已知类，出现ClassNotFoundException，示例代码如下： 修复前： private void robustAddMethod() { Log.e("mytag", "robustAddMethod"); } 修复后： @Modify private void robustAddMethod() { Log.e("mytag", "robustAddMethod"); Glide.with(this); showToast("新增showToast方法: " + Process.myPid() + " " + Glide.with(this).toString()); }

问题的关键在于，引用的类并不是新增类，但是这个类如果是我们自己写的，则可以通过把类标记为新增类来解决，但是引用的是第三方的类就没有办法了。

可以手动将这个类放到新补丁dex中 （1）将含有这个类的APK变成smali，找到这个glide类的smali （2）将补丁dex/apk变成smali （3）将（1）&（2）的smali文件合并，一起smali to dex，就得到了预期补丁
