As far as i can see, you could just use the normal Calendar instead of the in API 24 introduced ICU Calendar. Try to use this import java.util.Calendar instead of this import android.icu.util.Calendar.

From Calendar pick date:
import java.util.Calendar instead of this import android.icu.util.Calendar
And Then write those code code for Date Pick.
Calendar callForDate = Calendar.getInstance();
java.text.SimpleDateFormat currentDate = new java.text.SimpleDateFormat("dd-MMMM-yyyy");
final String saveCurrentDate = currentDate.format(callForDate.getTime());
