Remarks

Selects the class loader which will be used by the platform to instantiate app components.

The default implementation of this method returns the cl parameter unchanged. Applications can override this method to set up a custom class loader or a custom class loader hierarchy and return it to the platform.

The method is a hook invoked before any application components are instantiated or the application Context is initialized. It is intended to allow the application's classes to be loaded from a different source than the base/split APK(s).

The default class loader cl is created by the platform and used to load the application's base or split APK(s). Its parent is typically the boot class loader, unless running under instrumentation. Its classname is configurable using the android.R.attr#classLoader manifest attribute.
