Android emulator is being started again [SOLVED: Case sensitive emulator's name]

MrZigaS · March 27, 2019, 10:08am

Let me explain the problem like this. Normally when implementing new feature/test case, I would first run Appium desktop to see what element are on the screen in the app. That means I open Appium desktop, and to start inspection, I need to start Emulator in terminal running this command:

./emulator -avd {name_of_emulator}

… then, I inspect the elements, write some scripts etc…
Now, while Emulator is already running, I try to run this script by hitting Play button in IntelliJ and here is the problem. - New Emulator is trying to be started (with the same name) and I get this server error:

2019-03-27 10:06:21:095 [ADB] Emulator avd Nexus_5X_API_25 exited with code 1

The problem is, I can not start the test until I quit the emulator and let the test start it itself. Attaching to already running one is not an option, which can take several minutes to start (and is complete waste of time).

What can I do to get the test running without quitting the Emulator?

Note:

Setting ‘skipDeviceInitialization’ capability to TRUE will not solve this issue.
- Once the Emulator is run from test, next time I run the test again, it will take the running Emulator and will not try to start new one.
I’m not changing default ‘abdPort’ capability in test.

Can you enable debug logging and attach the updated log? In general the driver just tries to detect if the emulator with the given name (avd cap) is already running (see https://github.com/appium/appium-adb/blob/527c8b417d7b62717ececfdf068309b0ee4dbd8f/lib/tools/system-calls.js#L524) and only executes a new instance if it does not or if -wipe-data arg is provided: https://github.com/appium/appium-android-driver/blob/32bace944aaf4192e5736d0e4e6a0077534a6bd5/lib/android-helpers.js#L113

It looks like the current emulator name comparison algorithm is case sensitive. I’ll fix it, but you can just use exactly the same letter case for avd and the actual emulator name in order to workaround the problem

MrZigaS · March 29, 2019, 7:31am

I renamed emulator to lower case and the name of the emulator to use for testing and it works.
But before i had the same:

Avd Manager emulator’s name: Nexus_5X_API_25
Appium properties: Nexus_5X_API_25

… so it might need to be lower cased.

Thanks for your help!
