修改android 自带的class中的方法， 比如我是在Activity的onCreate中随便加一个依据打印.验证就出了这个问题

ava.lang.NoSuchMethodError: No virtual method getPackageName()Ljava/lang/String; in class Landroid/app/Activity_CF; or its super classes (declaration of 'android.app.Activity_CF' appears in /data/user/0/com.vivo.hotfixdemo/files/apatch/framework.apatch)

Begin with the failing call at android.app.Activity_CF.decideSpecialActivity(Activity.java:6915) and the generated framework.apatch named in the trace; compare that class's available methods with the runtime call path from onCreate. Reproduce the Activity.onCreate verification case, with completion marked by the reported NoSuchMethodError no longer occurring.
