How to detect ussd code on android app

Sofari Agali

I am trying to find out if there is a code that can detect USSD in newly received SMS and execute them automatically?

Firstly you will need SMS read access.

Secondly, you should be able to identify USSD codes. Those are tipically starting with the "*" character and ending with a "#" character. You can use the following regex to identify the USSD:
/^\*[0-9\*#]*[0-9]+[0-9\*#]*#$/
Lastly, you need to actually make a call to that number because you need to reach the GSM network in order to execute the USSD.

Reading USSD and reading sms both are seperate parts, detecting sms will require read/write sms permission.
