roDeviceInfoEvent

The roDeviceInfo component sends the roDeviceInfoEvent with the following predicates that indicate its valid event types:

Supported methods

isStatusMessage() as Boolean

Checks if the device status has changed. This method returns true if the device status has changed; otherwise, it returns false.

GetInfo() as Object

Checks the current status of the device. This method returns an roAssociativeArray containing one of the following members:

Member	Type	Description
audioGuideEnabled	Boolean	True if the screen reader is enabled. The audioGuideEnabled event will only ever get fired if ifDeviceInfo.EnableAudioGuideChangedEvent(true) called before entering the message loop
exitedScreensaver	Boolean	True if the screensaver was exited. The exitedScreensaver event will only ever get fired if ifDeviceInfo.EnableScreensaverExitedEvent(true) is called before entering the message loop
appFocused	Boolean	It is set to False when the System Overlay takes focus and True when the app regains focus
linkStatus	Boolean	True if the device currently seems to have an active network connection. The linkStatus event will only ever get fired if ifDeviceInfo.EnableLinkStatusEvent(true) is called before entering the message loop
generalMemoryLevel	String	Fires notifications to the app about memory levels. This event will be sent first when the OS transitions from "normal" to "low" state and will continue to be sent while in "low" or "critical" states. The events will be throttled so as to not overwhelm the application listening for these events. The application may voluntarily free up memory by invalidating references to objects (e.g. release ContentNodes held in a cache, release offscreen renderable nodes, etc.). The "low" and "critical" events will be sent to the OS forces the application to exit. "normal" means that the general memory is within acceptable levels "low" means that the general memory is below acceptable levels but not critical "critical" means that general memory are at dangerously low level and that the OS may force terminate the application
audioCodecCapabilityChanged	Boolean	The audio codec capability has changed if true. If your application receives this event, you can check the current audio playback capability using the `roDeviceInfo.CanDecodeAudio`asObject) and `roDeviceInfo.GetAudioDecodeInfo`asObject) methods. This event is only fired if the `ifDeviceInfo.EnableCodecCapChangedEvent(true)`) is called before entering the message loop.
videoCodecCapabilityChanged	Boolean	The video codec capability has changed if true. If your application receives this event, you can check the current video playback capability using the `roDeviceInfo.CanDecodeVideo`asObject) method. This event is only fired if `ifDeviceInfo.EnableCodecCapChangedEvent(true)`) is called before entering the message loop.

isCaptionModeChanged() as Boolean

Indicates whether the user has changed the closed caption mode or track. This method returns true if the caption mode changed; otherwise, it returns false.

Call the GetInfo() method to get the caption mode.

GetInfo() as Object

Indicates the current global setting for the Mode property, which may be one of the following values:

"On"
"Off"
"Instant replay"
"When mute" (Only returned for a TV; this option is not available on STBs).

EnableValidClockEvent(enable as Boolean)

Indicates whether the RokuOS has successfully connected to the network and contacted the timeserver in order to set the device's clock. Call the GetInfo() method to confirm that the system clock is valid.

GetInfo() as Object

This method returns an roAssociativeArray containing a validClock field that indicates whether the system clock is valid.

Member	Type	Description
validClock	Boolean	True if the system clock is valid.
