Requesting a Check Transaction Status for an Offline Sale Pending Submission

This section describes how to request a check transaction status for a single offline sale transaction before it is submitted for authorization. The transaction status displays on the Summary screen.
Follow these steps to request a check transaction status for an offline sale pending submission:
  1. Access the
    transactionIdentifier
     value in the
    onActivityResult
     method of the original transaction.
  2. Retrieve the transaction
    summaryIntent
     value from the
    mposUi
     object.
  3. Use the
    startActivity
     method to initiate the Summary screen.
    val summaryIntent = mposUi.offlineModule.createTransactionSummaryIntent(transactionIdentifier = "transactionIdentifier")
startActivityForResult(summaryIntent, MposUi.REQUEST_CODE_SHOW_SUMMARY)
  4. After the Summary screen is dismissed, the
    onActivityResult
     is triggered. This action returns information about the previous transaction.
    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) 
{
    super.onActivityResult(requestCode, resultCode, data)
    if (requestCode == MposUi.REQUEST_CODE_SHOW_SUMMARY) {
        when (resultCode) {
            // Result code from a successful transaction
            MposUi.RESULT_CODE_APPROVED -> {
               val transactionIdentifier = data?.getStringExtra(MposUi.RESULT_EXTRA_TRANSACTION_IDENTIFIER)
               Toast.makeText(findViewById(android.R.id.content),"Transaction approved!\nIdentifier: $transactionIdentifier", Toast.LENGTH_LONG).show()
            }
            // Result code from a declined, aborted or failed transaction
            MposUi.RESULT_CODE_FAILED -> {
               Toast.makeText(findViewById(android.R.id.content), "Transaction was declined, aborted, or failed", Toast.LENGTH_LONG).show()
            }
        }
    }
}
