Interface CefriumBrowser.DeviceChooserHandler

Enclosing class:

CefriumBrowser

public static interface CefriumBrowser.DeviceChooserHandler

Presents device chooser UI for the frontier web device APIs. Without a handler set, such requests are cancelled (the page promise rejects) — the engine has no built-in picker in this embedding. All methods are called on the UI thread.

Method Summary

Modifier and Type	Method	Description
void	onDeviceAdded(CefriumBrowser.DeviceChooserSession session, CefriumBrowser.ChooserDevice device)	A candidate device became available (called repeatedly while a Bluetooth scan runs; once per present device for USB/Serial).
void	onDeviceChooserClosed(CefriumBrowser.DeviceChooserSession session)	The engine closed the chooser (e.g.
default void	onDeviceRemoved(CefriumBrowser.DeviceChooserSession session, String deviceId)	A device previously reported to onDeviceAdded(com.cefrium.CefriumBrowser.DeviceChooserSession, com.cefrium.CefriumBrowser.ChooserDevice) is no longer available (e.g.
void	onShowDeviceChooser(CefriumBrowser.DeviceChooserSession session)	A chooser opened; present UI and keep session to resolve it.

Method Details

onShowDeviceChooser

void onShowDeviceChooser(CefriumBrowser.DeviceChooserSession session)

A chooser opened; present UI and keep session to resolve it.

onDeviceAdded

void onDeviceAdded(CefriumBrowser.DeviceChooserSession session,
 CefriumBrowser.ChooserDevice device)

A candidate device became available (called repeatedly while a Bluetooth scan runs; once per present device for USB/Serial). May repeat for the same id to update its label.

 String deviceId)

A device previously reported to onDeviceAdded(com.cefrium.CefriumBrowser.DeviceChooserSession, com.cefrium.CefriumBrowser.ChooserDevice) is no longer available (e.g. a USB/serial device was unplugged mid-chooser). Remove it from the picker. Not called for Bluetooth scans (which only add). Optional; the default does nothing.

onDeviceChooserClosed

void onDeviceChooserClosed(CefriumBrowser.DeviceChooserSession session)

The engine closed the chooser (e.g. navigation); dismiss the picker.
