Void Request

1. Perform void transaction

// Build the void transaction
private static final int VOID_REQUEST_CODE = 4;
   private void startVoid() {
       // Build the void request
       MyPOSVoid voidEx = MyPOSVoid.builder()
   			//.voidLastTransactionFlag(true) // this may void last transaction initialized by this terminal
   	// Start the void transaction
   	MyPOSAPI.openVoidActivity(MainActivity.this, voidEx, VOID_REQUEST_CODE, true);


2. Handle the result

The same as with the payment, in your calling Activity, override the onActivityResult method to handle the result of the void request:

	void onActivityResult(int requestCode, int resultCode, Intent data) {
	    if (requestCode == VOID_REQUEST_CODE) {
			// The transaction was processed, handle the response
			if (resultCode == RESULT_OK) {
				// Something went wrong in the Payment core app and the result couldn't be returned properly
				if (data == null) {
					Toast.makeText(this, "Transaction cancelled", Toast.LENGTH_SHORT).show();
				int transactionResult = data.getIntExtra("status", TransactionProcessingResult.TRANSACTION_FAILED);

				Toast.makeText(this, "Void transaction has completed. Result: " + transactionResult, Toast.LENGTH_SHORT).show();

				// TODO: handle each transaction response accordingly
				if (transactionResult == TransactionProcessingResult.TRANSACTION_SUCCESS) {
					// Transaction is successful
			} else {
				// The user cancelled the transaction
				Toast.makeText(this, "Transaction cancelled", Toast.LENGTH_SHORT).show();
