Countdown and android.os.*

So I needed a countdown timer for an Android project I'm working on and after building a simple one myself, a came across android.os.CountDownTimer - who knew android shipped with one!

That got me interested in having a browse through andriod.os.* package to see what else the Android devs had squirreled away in there...

Turns out a whole bunch of handy stuff!  Like:

• An simple API inotify
• PowerManager
• Filesystem stats
• a persistent, system-wide, blob-oriented "logcat"
• the very handy AysncTask
