In the previous lab, we looked at WeatherClock.db.
We know that the actual database tracks the most recent city
that the user had traveled to and that the wall
or write ahead log associated to that database
will track other recent searches.
Turbo.db-- Kevin wrote an awesome blog
that's based on turbo.db.
If you look in the notes of the book, you will find that.
What turbo.db does, it is supposed to track your battery.
So think about this--
just your battery.
What it's doing is looking at different battery levels.
But ready for the craziness?
It knows which time zone you're in every single time
it checks for battery status.
So a good example--
I flew from Eastern to Pacific.
When I landed on that plane, as soon
as I took my Android out of airplane mode,
it would check for battery level.
It would show Pacific time.
So it would have shown Eastern and then Pacific.
That is great proof of location and travel.
At least it gets you into the correct time zone.
