PreferenceManager getDefaultSharedPreferences deprecated in Android Q

Question

PreferenceManager getDefaultSharedPreferences is deprecated in Android Q, how do I replace it?

Answer 1

Package preference provides the androidx PreferenceManager:

Java: implementation "androidx.preference:preference:1.1.1"

Kotlin: implementation "androidx.preference:preference-ktx:1.1.1"

i.e. change android.preference.PreferenceManager to androidx.preference.PreferenceManager

---

Also see PreferenceFragmentCompat, which is the current PreferenceFragment class to use.
