After showcasing the Google Fit platform at the I/O developer conference, the search giant has now released the preview SDK for developers. This SDK can be used to start building fitness related applications and includes a single set of APIs for apps and device manufacturers to store and access activity data from fitness apps and sensors on Android and other devices like wearables.
Google Fit Product Manager Angana Ghosh writes in a blog post that with the new set of APIs and user permission, the developers will be able to access to the user’s fitness history — enabling them to provide features like personalized coaching, better insights, fitness recommendations and more.
Ghosh added that there are three basic set of APIs – Sensors, Recording, and History – to meet the developer needs regarding the fitness data.
The developers can now grab the preview SDK from Google website. In addition, Google has released an updated version of Google Play Services containing Google Fit APIs as a part of a new Android L preview builds for Nexus 5 and Nexus 7 (2013) devices.
The new build – LPV81C- only includes the new Play Services version and there are no other changes or bug-fixes. So, it is only useful for developers working on Google Fit related apps. Rest of you can remain happy with the older build – LPV79. The same has been confirmed by Google’s Jamal Eason on his Google+ page.
Developers can find more information about Google Fit Preview SDK and the process of build related apps in this blog post from Ghosh.
