Android gets an emulator with a device name, or vice versa

Question

Currently, when I run adb devices , it gives me a list of devices that look something like this:

 emulator-5554 device emulator-5556 device 

My goal is to find a command that I can run in a shell that takes a device name as a parameter, for example. Nexus7 and returns the corresponding serial number of the device, for example. emulator-5554 . If this is not possible, I want to have a function that takes emulator-5554 as a parameter and returns Nexus7 (the opposite direction of the previous function), after which I will Nexus7 over all devices in adb devices and find out which one corresponds to Nexus7 .

UPDATE

I found a workaround that should have indicated the port number when running avd, and then I know which emulator maps to which avd name, but ideally I would still like to know the answer here.

Answer 1

This is possible using telnet for the emulator. Unfortunately, this is not one command, but in general it can be automated using the shell. Here is the basic idea:

• Find the emulator port number (5554):

   $ adb devices List of devices attached emulator-5554 device 

• Telnet for emulator:

   $ telnet localhost 5554 Trying 127.0.0.1... Connected to localhost. ... OK avd name Nexus7 

Nexus7 is the name avd.

Answer 2

• get the PID list for all running emulator processes
• analyze their cmdlines, collect avd names
• check TCP ports opened by these processes
• map open ports to adb devices output
