take two consecutive ports from 5555 to 5585. The odd port is responsible for connecting to ADB, and the even port is responsible for connecting to the console. The server scans the odd ports between 5555 and 5585 to find the simulator or device instance and establishes a connection with the found port. Once the server is connected to all simulators or devices, you can use the ADB command to control and
