 [DroneKit-Android](http://android.dronekit.io/) is the implementation of [DroneKit](http://dronekit.io/) on Android.
 
-The API provides interfaces that apps can use to control copters, planes, and ground vehicles. It is compatible with vehicles that communicate using the MAVLink protocol (including most vehicles made by 3DR and other members of the DroneCode foundation), and is validated against the open-source [ArduPilot flight control platform](ardupilot.com).
