AndroidEnv does not work in WSL

I’ve setup android studio on windows and am trying to load the environment from WSL. I have got an unexpected keyword argument 'use_poll' error while trying to load the environment. Any ideas on how I can fix this?

Full error:

>>> import android_env
>>> env = android_env.load(avd_name='Pixel_2_API_30', android_avd_home='/mnt/c/Users/Surya Penmetsa/.android/avd/Pixel_2_API_30.avd', android_sdk_root='/mnt/c/Users/Surya Penmetsa/AppData/Local/Android/Sdk', emulator_path='/mnt/c/Users/Surya Penmetsa/AppData/Local/Android/Sdk/emulator/emulator.exe', adb_path='/mnt/c/Users/Surya Penmetsa/AppData/Local/Android/Sdk/platform-tools/adb.exe', task_path='downloads/classic_2048.textproto')

Hello @psurya1994, it’s ok to leave it open. We are also planning to use a different communication mechanism (gRPC) which could help here and remove the need for this particular pexpect call. Eventually we do want to support running on Windows via WSL. Tagging @a-gergely who’s been experimenting with gRPC.

Thanks,

Daniel

Hello @psurya1994, we have never tried running AndroidEnv on Windows, so thanks for the report.

From the error message, it looks like it’s a limitation in one of the libraries we use, pexpect, which does not offer popen.spawn on Windows. According to their docs, we can try to see if we can use PopenSpawn but it would be better if you can try it in your local machine and report back to us since we don’t have Windows machines to try.

Let me know what you think,

Thanks!
