Activity's incapability with androidx

Question

I encountered to a problem related to Activity's getFragmentManager() incossitency with androidx.FragmentManager.

So I have the following method:

public void myMethod(Activity activity) {
    /**
     * do some staff here
     */
    
    //now we should open a DialogFragment
    new MyCustomDialogFragment().show((activity).getFragmentManager(), MyCustomDialogFragment.TAG);
    
}

and here I'm getting error "Can not resolve method show(android.app.FragmentManager, java.lang.String).

All these because my DialogFragment is from androidx.fragment.app package when Activity's getFragmentManager() returns FragmentManager from android.app package.

I see 2 options to solve this.

1. Change dependency of DialogFragment, and use the one from android.app
2. Change myMethod() signature to receive AppCompatActivity (from androidx) instead of Activity and call getSupportedFragmentManager().

First solution is not good as I want to keep using androidx classes everywhere possible. Second is also has drawbacks despite of AppCompatAcivitity is a best practice.

Question is : Is there a way to keep using androidx dependency and having Activity type parameter inside myMethod() ?

Answer 1

You should use FragmentActivity (from androidx) instead of Activity as the argument type in myMethod() and call getSupportFragmentManager() to get the FragmentManager on it. This should solve your problem.
