User  janot has already mentioned this above  but this took me some time to filter the best solution   There are two Broad use cases  1  2 hardware are connected  first is emulator and other is a Device  Solution   adb -e shell    whatever-command for emulator and adb -d shell    whatever-command for device   2  n number of devices are connected  all emulators or Phones Tablets  via USB ADB-WiFi  Solution   Step1  run adb devices THis will give you list of devices currently connected  via USB or ADBoverWiFI  Step2  now run adb -s  lt device-id IP-address gt  shell    whatever-command no matter how many devices you have   Example to clear app data on a device connected on wifi ADB I would execute  adb -s 172 16 34 89 5555 shell pm clear com package-id  to clear app data connected on my usb connected device I would execute  adb -s 5210d21be2a5643d shell pm clear com package-id
