ReaderEvents¶

public interface ReaderEvents¶

Interface used to received smart card reader events.

The methods are not called within the context of the main UI thread. If UI actions must be made within these methods, you can delegate the operation to android.app.Activity.runOnUiThread(Runnable), or post a Runnable to the UI thread through a android.os.Handler.

Also note that due to system restrictions, it is only possible to correctly report events when the Smart Card Middleware application is in foreground (not the target application). See SCMEnvironment.openWaitForTokenDialog(Activity).

Methods¶

onReaderAdded¶

void onReaderAdded(Reader reader)¶

Called when a new reader is plugged on the device, or a bluetooth reader discovered.

Parameters:	reader – the new `Reader` object.

onReaderRemoved¶

void onReaderRemoved(Reader reader)¶

Called when a reader is unplugged from the computer.

Parameters:	reader – the removed `Reader` object.

onReaderStateChanged¶

void onReaderStateChanged(Reader reader)¶

Called when the state of a reader changes (e.g. insertion or withdrawal of a card, …).

Parameters:	reader – the affected `Reader` object. Its properties can be consulted (e.g. using `Reader.getStatus()`, `Reader.isCardPresent()`, …) to obtain more information about the event.

onTokenArrival¶

void onTokenArrival(Reader reader)¶

Called when a token becomes available on a reader.

Note: this method is called from the default implementation of the onReaderXXX methods, and can’t be used if their implementation is overridden. You have to either use the onReaderXXX or the onTokenXXX events, but you cannot use both.

Parameters:	reader – the `Reader` in which the token is located.

onTokenRemoval¶

void onTokenRemoval(Reader reader)¶

Called when a token is made unavailable (by removing it from the reader, or when the reader is removed).
