7. Status & Utility Methods

These synchronous helper methods let you inspect the current state of the SDK and the underlying hardware at any time after initialize() succeeds.

Method Reference

Method	Returns	Description
isServiceAlive()	Boolean	Returns true if hardware service is connected.
getDetectedOEM()	OEM	Returns the detected OEM enum value.
isPrinterReady()	Boolean	Returns true if printer is ready.
cancelTransaction()	Unit	Requests cancellation of current transaction.

isServiceAlive()

if (pos.isServiceAlive()) {
    // Hardware service is connected
    // Safe to call startPayment()
}

if (pos.isServiceAlive()) {
    // Hardware service is connected
    // Safe to call startPayment()
}

getDetectedOEM()

val oem = pos.getDetectedOEM()
Log.d(TAG, "Running on: $oem")

OEM oem = pos.getDetectedOEM();
Log.d(TAG, "Running on: " + oem);

isPrinterReady()

if (pos.isPrinterReady()) {
    pos.print(receiptBitmap) { ok, msg ->
        Log.d(TAG, "Print result: $ok")
    }
} else {
    Log.w(TAG, "Printer not ready")
}

if (pos.isPrinterReady()) {
    pos.print(receiptBitmap, (ok, msg) ->
        Log.d(TAG, "Print result: " + ok));
} else {
    Log.w(TAG, "Printer not ready");
}

cancelTransaction()

// Call this if you need to abort an in-progress transaction
pos.cancelTransaction()

// Call this if you need to abort an in-progress transaction
pos.cancelTransaction();

ℹ️

NOTE Cancellation is a request — the SDK will call onCancelled() on the PaymentResultListener once the hardware acknowledges the cancel.
