When Google added a pedometer to Android 4.4 on the Nexus 5, we should have guessed that it was only the beginning. Code for a fitness API that was recently discovered (shown after the break) would allow fitness apps to view and edit your fitness tracking and health and activities data. This includes reading and writing raw and transformed data.

The code hints at the ability to gather the information from your device's sensors, and may even let developers combine data from multiple sources to give you an even more detailed view of your workout. There's not a lot that we know about this code currently, including when (or if) it will be included in a future Android release or a Google Play Services update, but fitness enthusiasts shouldn't be too surprised if their favorite app becomes even more useful.
