title: How to Get Serial Number or ID of Android Emulator After it Runs?
body: <p>If I run several emulators with -no-window option in one machine. The command "adb devices" shows:</p>
  
  <pre><code>List of devices attached
  emulator-5554  device
  emulator-5556  device
  emulator-5558  device
  ...
  </code></pre>
  
  <p>However, according to this output, I can't tell the difference between each emulator device at all. I need to know which emulator runs on what AVD, then I can install APKs or send commands to the emulator.</p>
  
  <p>How can I recognize each emulator device or get the serial number of emulator after it runs?</p>
