onInputUpdated

Added in API level 24

open fun onInputUpdated(inputId: String!): Unit

onTvInputInfoUpdated

Added in API level 24

open fun onTvInputInfoUpdated(inputInfo: TvInputInfo!): Unit

This is called when the information about an existing TV input has been updated.

Parameters
`inputInfo`	TvInputInfo!: The `TvInputInfo` object that contains new information.
