I am creating an app where the user fills a form and sends an SMS to a phone number. The app then logs the data to a csv file. The app should record data when SMS is sent but exactly opposite is happening. The data is recorded when SMS is not sent and data is not recorded when SMS is sent, could anyone kidly help? Here is my code and XML file.
Code:
