Google has released updated images of the Android L developer preview. The new images weigh in as build LPV81C and are still only available to the Nexus 5 and Nexus 7 (2013) WiFi. This is an upgrade from the LPV79 build that was released in late June.
Not much has been changed in the images however, Google does note that developers should download these new images and not the ones on the main Android Developers page since the new LPV81C images “include the necessary support for Google Fit,”. In addition to releasing the developer preview, Google has also made Google Fit SDK available for developers.
“The preview SDK gives you the tools to start building your app. You’ll be able to launch your app later this year when we launch the full Google Fit SDK as part of Google Play services for handsets, Android Wear and also for the web”
said Google in a company blog post.
The Google Fit Preview SDK includes the three sets of APIs that developers will need to begin building apps that take advantage of Google Fit. Those include the Sensors API for high-level access to sensors from devices and wearables, a Recording API to gather a cloud-synced background of fitness data and a History API that lets apps read, insert and delete data. These sensors can exist on health devices like fitness wearables, smartwatches (with sensors), heart rate monitors, and connected scales.
