[AOSP] APK Signature Scheme v2 verification

[Jacky Lam]

Hi All,

I am new to Android OS building. I am now trying to realize hows APK Signature Scheme v2 verification operates in system level.

I would like to know which part of android system is responsible for verifying incoming, new APK with APK Signature Scehem v2?

Is it "ApplicationPackageManger.java" inside frameworks/base/core/java/android/app?

Or I need to refer to other path location?

Thanks.

Jacky
