ANDROID_ADB_SERVER_PORT to select the port. $adb -P 5038 start-server

http://stackoverflow.com/questions/3836571/changing-default-port-i-e-5037-on-which-adb-server-runs

Use the environment variable ANDROID_ADB_SERVER_PORT to select the port. The following works under bash: $ export ANDROID_ADB_SERVER_PORT=12345 $ adb start-server * daemon not running. starting it now on port 12345 * * daemon started successfully * $ adb devices List of devices attached TA2070M5O6 device $ ANDROID_ADB_SERVER_PORT=6789 adb devices * daemon not running. starting it now on port 6789 * * daemon started successfully * List of devices attached In another terminal I ran: $ ANDROID_ADB_SERVER_PORT=6789 emulator ... Back to original terminal: $ ANDROID_ADB_SERVER_PORT=6789 adb devices List of devices attached emulator-5554 device $ adb devices # ANDROID_ADB_SERVER_PORT was exported as 12345 List of devices attached TA2070M5O6 device I found this via the Jenkins Android Emulator Plugin as I noticed it was running adb on a different port. shareimprove this answer answered Jun 2 '12 at 18:52 ashley willis 35338

With the latest adb version, Use option -P (Note: Caps P)to start adb server in a specific port. For Example, Try $adb -P 5038 start-server It will list the devices attached to this specific adb server. If the adb server is not running then it will start a new adb server with the given port number. Hope it helps someone reading this post. Thanks.
