The picker in frameworks/base does the simpler job: when called it returns one locale only, no knowledge of locale lists. The previous com.android.internal.app.LocalePicker shows a list of locales based on the localised resources available. The replacement (LocalePickerWithRegion) shows a more complete list (a curated subset of all the ICU locales, but still pretty big). Because of the length of the list the LocalePickerWithRegion splits the selection in two: you first select the language, and then the region (where that language is used). If you need to select one of the locales completely supported by the system (that have translated UI), continue to use com.android.internal.app.LocalePicker They should be compatible: they show some UI and end up selecting a locale. Beyond the UI differences, LocalePickerWithRegion will return more "granular" locales (tens of French, or Spanish, or English locale variants).
