java.lang.ClassCastException: android.app.Application cannot be cast to androidx.appcompat.app.AppCompatActivity

Question

I have a problem regarding adapter in fragment. It throws a typo shown below.

java.lang.ClassCastException: android.app.Application cannot be cast to androidx.appcompat.app.AppCompatActivity

Here is the code snippet.

SongDetailFragment fragment =
                        SongDetailFragment.newInstance(selectedSong);
                AppCompatActivity activity = (AppCompatActivity) view.getContext().getApplicationContext();
                activity.getSupportFragmentManager().beginTransaction()
                        .replace(R.id.song_detail_container, fragment)
                        .addToBackStack(null)
                        .commit();

How can I fix it?

in which class is this code written?

In your Fragment use:

AppCompatActivity activity = (AppCompatActivity) getActivity();

instead of:

AppCompatActivity activity = (AppCompatActivity) view.getContext().getApplicationContext();
