input

The sos.input API groups together all input-related functionality, such as remote control key events. With this API, you can listen to key events from the remote control and handle them in your application.

Methods

onKeyUp()

The onKeyUp method sets up a listeners, which is called on every keystroke of the remote controller. For the specific logic of an application (games for example), binding the remote control inputs can be helpful. Only a subset of all remote control keys is supported on the specific device. Only numerical digits are guaranteed to be supported.

This feature must be tested by users on real devices.
