1. Problem Using Source Code for Alarm Clock

I am a bit stuck here.  I think I am missing something obvious but
just can't figure out what it is.  I have been trying to load the
original source code for "Alarm Clock" into Eclipse, but the code
shows an error in DigitalClock.java - "mContext cannot be resolved".
I have looked in a number of releases, and paste the code in exactly,
but always the same error - "mContext cannot be resolved".

I have tried to "fix" the code various ways but to no avail.  But then
this is the working original source code, so of course should not
requiring fixing .....

Any ideas would be appreciated.

Thanks,
Matt

Here is the DigitalClock.java code.
