How to identify an android emulator (AVD) using ADB

Question

I use the emulator AVD and i have 3 android :

• First name Android : test
• Second name Android : test1
• Third name Android : test2

I launch the first and second android with command line :

emulator -avd test
emulator -avd test1

And after, when i use this command line :

avd devices

I have

List of devices attached
emulator-5556 device
emulator-5554 device

How i can identify my android emulator with adb (only command line)?
If it's impossible, how I can know if my device is started with "emulator" (only command line) ?

Answer 1

Try doing a TELNET to the AVD

emulator -avd test
emulator -avd test1

avd devices

List of devices attached 
emulator-5556 device 
emulator-5554 device

telnet localhost 5554
Trying 127.0.0.1...
Connected to localhost.
...
OK
avd name
test1
