Since the Android getFragmentManager() API is deprecated, is there any alternative?

Question

FragmentManager is deprecated. Is there an alternative or what can I do now?

 PlaceAutocompleteFragment autocompleteFragment = (PlaceAutocomplet         


        

Answer 1

I used parentFragmentManager instead of fragmentManager. (If you are using androidx Fragment.)

https://developer.android.com/jetpack/androidx/releases/fragment#1.2.0

getFragmentManager() deprecation: The getFragmentManager() and requireFragmentManager() methods on Fragment have been deprecated and replaced with a single getParentFragmentManager() method, which returns the non-null FragmentManager the Fragment is added to (you can use isAdded() to determine if it is safe to call).

Answer 2

Xml

<fragment
    android:id="@+id/place_autocomplete_fragment"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:name="com.google.android.gms.location.places.ui.SupportPlaceAutocompleteFragment"
/>

Activity

SupportPlaceAutocompleteFragment autocompleteFragment = (SupportPlaceAutocompleteFragment)
            getSupportFragmentManager().findFragmentById(R.id.place_autocomplete_fragment);

Answer 3

This method was deprecated in API level 28.

Use FragmentActivity.getSupportFragmentManager()

Answer 4

If you using AndroidX Fragment androidx.fragment.app.Fragment you can use

getActivity().getSupportFragmentManager()

Answer 5

Use This

import android.support.v4.app.FragmentManager;

Instead of

import android.app.FragmentManager;

And Use This

FragmentManager manager = ((YourActivity) mContext).getSupportFragmentManager();

Instead of

 FragmentManager manager = ((YourActivity) mContext).getFragmentManager();

Answer 6

You should use the Fragment class from Android Support library instead.

android.app.Fragment was deprecated in API level 28. Use the Support Library Fragment for consistent behavior across all devices and access to Lifecycle.

Use android.support.v4.app.Fragment instead.
