DeviceWearableButtonsProvider

public DeviceWearableButtonsProvider ()

Public methods

getAvailableButtonKeyCodes

public int[] getAvailableButtonKeyCodes (Context context)

Get the keycodes of available hardware buttons on device. This function based on key's locations from system property. This count includes the primary stem key as well as any secondary stem keys available.

Parameters
`context`	`Context`: The context of the current activity

Returns
`int[]`	An int array of available button keycodes, or null if no keycodes could be read.

getButtonInfo

public Bundle getButtonInfo (Context context, 
                int keycode)

Returns a bundle containing the metadata of a specific button. Currently, only location is supported. Use with WearableInputDevice.X_KEY and WearableInputDevice.Y_KEY. The key will not be present if the information is not available for the requested keycode.

The location returned is a Cartesian coordinate where the bottom left corner of the screen is the origin. The unit of measurement is in pixels. The coordinates do not take rotation into account and assume that the device is in the standard upright position.

Parameters
`context`	`Context`: The context of the current activity
`keycode`	`int`: The keycode associated with the hardware button of interest

Returns
`Bundle`	A `Bundle` containing the metadata for the given keycode
