Void Request

1. Perform a 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()
					
						
						
               .STAN(27)
					
						
						
               .authCode("VISSIM")
					
						
						
               .dateTime("180129123753")
					
						
						
   	//.voidLastTransactionFlag(true) // this may void last transaction initialized by this terminal
					
						
						
               .build();
					
						
						
   			
					
						
						
   	// 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:

						
						
@Override
					
						
						
	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();
					
						
						
					return;
					
						
						
				}
					
						
						
				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();
					
						
						
			}
					
						
						
		}
					
						
						
    }
