transceive() blocking UI thread [android] #18

Open

ghost opened this issue May 28, 2020 · 0 comments · May be fixed by #19

Calls to "transceive", "connect" and "close" methods currently blocks the UI and therefore should be called inside a background thread.

To reproduce:

Place CircularProgressIndicator(value: null) in the widget tree
Inside your "onDiscovered", call tag.transceive(data)
The progress indicator stutters for a brief amount of time

Relevant: https://developer.android.com/reference/android/nfc/tech/IsoDep#transceive(byte[])

This is an I/O operation and will block until complete. It must not be called from the main application thread.
