Demo

Before

class HookEntry : IXposedHookLoadPackage {
    
    companion object {
        const val TAG = "CustomTAG"
    }
    
    override fun handleLoadPackage(lpparam: XC_LoadPackage.LoadPackageParam) {
        if (lpparam.packageName == BuildConfig.APPLICATION_ID) {
            XposedHelpers.findAndHookMethod(
                Activity::class.java,
                "onCreate",
                Bundle::class.java,
                object : XC_MethodHook() {
                    override fun afterHookedMethod(param: MethodHookParam?) {
                        Log.i(TAG, "Activity created!")
                    }
                }
            )
        }
    }
}

After

@XposedEntry
class HookEntry : HookHelper("CustomTAG") {
    override fun onHook() = handle {
        onLoadPackage(BuildConfig.APPLICATION_ID) {
            Activity::class.java.hook {
                method({ name == "onCreate" }) {
                    Logger.i("Activity created!")
                }
            }
        }
    }
}
