When I cloned Android's default alarm in Anroid Open Source Project @ https://android.googlesource.com/platform/packages/apps/DeskClock/ and tried to run it on Android Studio I got the following error:
package com.android.datetimepicker.time does not exist
cannot find symbol class TimePickerDialog
cannot find symbol class RadialPickerLayout <anonymous
com.android.deskclock.alarms.TimePickerCompat$TimerPickerPreL$1> is
not abstract and does not override abstract method
processTimeSet(int,int) in OnTimeSetListener
Please help in any way. Thank you.
