Fix findbugs issues

Constants should be private static final.
Since I'm there, renamed TAG to LOGTAG so it is obvious it is only used for logging.

I was looking at the find bugs list. A lot of them have simple fixes, so why not
just fix them. This is the first.

We use TAG everywhere (I think it's fairly typical) but this is fine. Thanks for
the clean-up!

Thanks! Renamed it back to TAG, that was not the important part.
