How are these two calls to get Locale different?

Question

In Android, What are these calls to get Locale different:

Locale.getDefault()

and

getResources().getConfiguration().locale

Answer 1

The locale selected on the device when the app was launched is the default locale returned by:

Locale.getDefault()

The locale currently selected on the device is the current locale (can be different from the default locale if the user changed the setting after the app launch) returned by:

getResources().getConfiguration().locale
