Android works finest when it helps builders create apps that folks love. That’s why we’re devoted to offering helpful APIs like Activity Recognition which, with the consumer’s permission, can detect consumer’s actions (equivalent to whether or not a consumer is biking or strolling) to assist apps present contextually conscious experiences.
A lot of what we do depends on a very good night time’s relaxation. Our telephones have grow to be nice instruments for making extra knowledgeable selections about our sleep. And by being knowledgeable about sleep habits, individuals could make higher selections all through the day about sleep, which impacts issues like focus and psychological well being.
In an effort to assist our customers keep knowledgeable about their sleep, we’re making our Sleep API publicly accessible.
What’s the Sleep API?
The Sleep API is an Android Exercise Recognition API that surfaces details about the consumer’s sleep. It may be used to energy options just like the Bedtime mode in Clock.
This sleeping info is reported in two methods:
- A ‘sleep confidence’, which is reported at a daily interval (as much as 10 minutes)
- A every day sleep phase which is reported after a wakeup is detected
The API makes use of an on-device synthetic intelligence mannequin that makes use of the machine’s gentle and movement sensors as inputs.
As with all of our Exercise Recognition APIs, the app should be granted the Bodily Exercise Recognition runtime permission from the consumer to detect sleep.
Why is that this vital for builders?
Builders spend priceless engineering time to mix sensor indicators to find out when the consumer has began or ended actions like sleep. These detection algorithms are inconsistent between apps and when a number of apps independently and constantly verify for adjustments in consumer exercise, battery life suffers.
The Sleep API is a straightforward API that centralizes sleep detection processing in a battery-efficient method. For this launch, we’re proud to collaborate with Urbandroid, the developer of the favored alarm app, Sleep As Android

Sleep as Android is a swiss military knife for getting a greater night time’s relaxation. It tracks sleep length, regularity, phases, loud night breathing, and extra. Sleep Period is among the most vital parameters to look at for making certain a very good night time’s relaxation. The brand new Sleep API provides us a unbelievable alternative to trace it robotically in essentially the most battery environment friendly means possible.

When can I begin utilizing this API?
The Sleep API is accessible for builders to make use of now as a part of the latest version of Google Play Services.
This API is one step of our efforts to assist our customers get a greater night time’s relaxation. We look ahead to working extra on this API and on this space sooner or later.
