Can't resolve symbol PreferenceFragmentCompat

Question

I'm trying to set up my SettingsFragment using PreferenceFragmentCompat but android studio give an error that Can't resolve symbol PreferenceFragmentCompat ... I'm using android studio 3.6.2

Answer 1

In your app's build.gradle make sure you have the corect dependency:

implementation 'androidx.preference:preference:1.1.0'

Then in your SettingsFragment import the library

Kotlin:

class SettingsFragment : PreferenceFragmentCompat() { }

Java:

public class SettingsFragment extends PreferenceFragmentCompat { }
