prevent loading of class specified by "zygotePreloadName"

[Karanveer7921]

I have an app with a class which implements ZygotePreload and mention it in AndroidManifest.xml's application tag with android:zygotePreloadName="<reference to the class>". This app here do some root detection, intergrity check, etc by loading a native shared lib. This part of code i.e loading of native lib is done before the handleLoadPackage method , so I can't place hooks here since app does its task before handleLoadPackage is invoked and hooks are placed. Then I decided to use initZygote(StartupParam startupParam). I dig into the system framework and found that class com.android.internal.os.AppZygoteInit$AppZygoteConnection has a method handlePreloadApp(ApplicationInfo appInfo) which invokes the doPreload method of that class which implements class ZygotePreload. I tried to place hooks here, initially I just tried to log com.android.internal.os.AppZygoteInit$AppZygoteConnection #handlePreloadApp(ApplicationInfo appInfo) this method call and it didn't worked. The hook was placed but the code I wrote in hook never got executed. This means, the class defined in android:zygotePreloadName is loaded even before initZygote method. How can I hook handlePreloadApp(ApplicationInfo appInfo) method of class com.android.internal.os.AppZygoteInit$AppZygoteConnection ?
