Public methods

onInputAdded

Added in API level 21

public void onInputAdded (String inputId)

This is called when a TV input is added to the system.

Normally it happens when the user installs a new TV input package that implements TvInputService interface.

Parameters
`inputId`	`String`: The ID of the TV input.

onInputRemoved

Added in API level 21

public void onInputRemoved (String inputId)

This is called when a TV input is removed from the system.

Normally it happens when the user uninstalls the previously installed TV input package.

Parameters
`inputId`	`String`: The ID of the TV input.

onInputStateChanged

Added in API level 21

public void onInputStateChanged (String inputId, 
                int state)

This is called when the state of a given TV input is changed.

Parameters

inputId

String: The ID of the TV input.

state

int: State of the TV input. The value is one of the following:

Value is TvInputManager.INPUT_STATE_CONNECTED, TvInputManager.INPUT_STATE_CONNECTED_STANDBY, or TvInputManager.INPUT_STATE_DISCONNECTED

onInputUpdated

Added in API level 24

public void onInputUpdated (String inputId)

This is called when a TV input is updated on the system.

Normally it happens when a previously installed TV input package is re-installed or the media on which a newer version of the package exists becomes available/unavailable.

Parameters
`inputId`	`String`: The ID of the TV input.

onTvInputInfoUpdated

Added in API level 24

public void onTvInputInfoUpdated (TvInputInfo inputInfo)

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

Because the system automatically creates a TvInputInfo object for each TV input based on the information collected from the AndroidManifest.xml, this method is only called back when such information has changed dynamically.

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