USSD Aplication for Android and IOS:

Hello there, I want an Application that works on both Android and IOS, it should consists of only one page (Activity) that contains only one button, when this button is pressed, the application should Automatically run an USSD code to a USSD server, the USSD code should be like this: *222*2000*0xxx xxx xxxx# The application should listen to the reply that the USSD server sends back, when the USSD reply come back; The application should read it and automatically send back number "1" as a reply to that USSD message (which acts as a confirmation to the server message). The application should be able to read the content of the USSD message. The application should not allow the USSD message to be displayed on the screen as an SMS message or a notification (to prevent the user from interacting with that USSD message outside this application). Thanks a lot, for
