NfcManager

Manages the Android NFC foreground dispatch lifecycle for EidKit sessions.

Attach to your Activity's lifecycle to receive card tap events:

class MyActivity : ComponentActivity() {
    private val nfcManager = EidKit.nfcManager()

    override fun onResume()  { super.onResume();  nfcManager.enableForegroundDispatch(this) }
    override fun onPause()   { super.onPause();   nfcManager.disableForegroundDispatch(this) }
    override fun onNewIntent(intent: Intent) {
        super.onNewIntent(intent)
        nfcManager.handleIntent(intent)?.let { isoDep -> startSession(isoDep) }
    }
}

All dispatch is scoped to the foreground activity — the system will not deliver NFC tags to other apps while your activity is in the foreground.

Functions

disableForegroundDispatch

fun disableForegroundDispatch(activity: Activity)

Disable foreground NFC dispatch. Call from Activity.onPause. Safe to call even if NFC is unavailable — no-op in that case.

enableForegroundDispatch

fun enableForegroundDispatch(activity: Activity)

Enable foreground NFC dispatch for the given activity. Call from Activity.onResume.

handleIntent

fun handleIntent(intent: Intent): IsoDep?

Extract an IsoDep tag from an NFC intent delivered to Activity.onNewIntent.

isNfcAvailable

fun isNfcAvailable(activity: Activity): Boolean

Returns true if the device has NFC hardware and it is currently enabled.
