How to inject android application class with DispatchingAndroidInjector in dagger 2

Question

I am trying to create a constructor for android application class for injecting DispatchingAndroidInjector as I would like to inject in constructor instead of field injection. Whenever I try to inject inside application class constructor, 'application class has no zero argument' exception is received.

Following way I am trying to inject dependency in application class :

    DispatchingAndroidInjector<Activity> mDispatchingAndroidInjector;

    @Inject
    public MyApplication(DispatchingAndroidInjector<Activity> dispatchingAndroidInjector) {
        mDispatchingAndroidInjector = dispatchingAndroidInjector;
    }

Provide the code – Rajnish suryavanshi Sep 24 '19 at 07:10 — Rajnish suryavanshi, Sep 24 '19 at 07:10

Unless you are using AppComponentFactory, which is available from API 28 only, your application class must have a default no-arg constructor. It basically means you can't use constructor injection for the application class.
