It is impossible to directly use the Android terminal to directly initiate a request to WeChat. WeChat card payment on the Android side is similar to an external device with a scanner.

All Android needs is to send the value after scanning the code according to the interface provided by the background. Personally, I have taken it over. It is best to start connecting from the back end and then develop mobile functions.
