Instances and handles commands from multiple adb clients, you can control any emulator/device Because the server manages connections to emulator/device Once the server has set up connections to all emulator instances, you can use adb commands toĪccess those instances. For example:Īs shown, the emulator instance connected to adb on port 5555 is the same as the instance Note that each emulator/device instance acquires a pair of sequential ports - an even-numbered port for console connections and an odd-numbered port for adb connections. Where the server finds an adb daemon, it sets up a connection to that port. It locates emulator/device instances by scanning odd-numbered ports in the range 5555 to 5585, the range used by emulators/devices. The server then sets up connections to all running emulator/device instances. It binds to local TCP port 5037 and listens for commands sent from adb clients-all adbĬlients use port 5037 to communicate with the adb server. If there isn't, it starts the server process.
