This trigger will fire when the device detects you are performing a certain activity such as moving in a vehicle, riding a bicycle or running. You can set a certainty value to control how easily the trigger will fire. A low certainty value is more likely to trigger but could potentially result in false triggers. A higher value should avoid false triggers but could fail to trigger in some cases where it should.

The underlying functionality of the Activity Recognition trigger is provided by Google Play services. The reliability of the trigger may be improved by enabling bluetooth, wifi and location services as these are fed into the recognition algorithm. <br>
Supported configurations:

Confidence value:
Set a confidence value required to invoke the trigger.
A low value may result in more false triggers and a high value may prevent the trigger from firing in some situations.

Example Usage:
When the activity is recognized (in the vehicle) it connects to the car's bluetooth and will start the music on spotify (if your music application is not active in the background, it may need additional configuration.
