Gamepad API support for chrome on android
This change adds code to get gamepad data from java objects and
provide these updates to the GamepadProvider which then writes to
GamepadHardwareBuffer which in turn is read by SharedMemoryReader and
later returned by JS to the web page.
This also adds new framework classes/methods required for Gamepad API
support. Frameworks changes are responsible for :
- Identifying gamepad devices and their capabilities.
- Managing connected gamepad devices
- Map the connected gamepad devices to standard Gamepad format.
- Keeping gamepads axes/buttons data up-to-date and returning it to
native whenever requested. In android we cannot get gamepad data
directly from sources, so framework is modified to capture
gamepad key and motion events and extract gamepad data from these
events.
* Class GamepadPlatformDataFetcherAndroid : Android specific
implementation of gamepad data fetcher.
- Responsible for communication with java class and accessing gamepad data.
- It adds methods for communication with singleton java GamepadList class
to get gamepads data.
* Class ContentViewCore : Manages gamepad list and notifies of new
key/motion event for gamepads.
* Class GamepadList : A new class to manage connected gamepad devices
* Class GamepadDevice : A new class to manage information related to
each gamepad device.
* Class GamepadMappings : This class is responsible for mapping of
known gamepads to the standard gamepad.
This change enables gamepad API by default.
Adds support for parsing float array return type in JNI generator.
NVIDIA Shield and XBox360 gamepads are mapped to the standard gamepad
