command failed: cmd='adb emu kill'

[Alecsplus]

On my Linux PC, nexus 6 screenshot for 1 language is OK.

When I try to use another localization, when I starts the screenshots command I receive this error:
command failed: cmd='adb emu kill'
after the first language ends its work.

Here the full log:

`alessandroid@TUXEDO:~/Developer/PFP/testFlutter/flutter_app$ /home/alessandroid/.pub-cache/bin/screenshots
Warning: 'Nexus 6P' does not have a matching emulator.
: Using 'Nexus_6P_API_Q'.
Warning: Flutter integration tests do not work in multiple locals.
See comment on issue:
flutter/flutter#27785 (comment)
for details.
and provide a thumbs-up on the comment to prioritize a fix for this issue!

In the meantime, while waiting for a fix, only use the default locale
in screenshots.yaml

It looks like you are running into 2 problems, one related to adb version number, the other, and more significantly, related to a flutter driver bug when running internatationalisation.

The flutter driver bug prevents you from generating screenshots in any non-default locale. The workaround for the moment is to run screenshots in just the default locale (by removing multiple locales in screenshots.yaml).

Try running screenshots in just the default locale and let me know what happens.

For anyone reading this, please give a 👍 to the issue at:

Dear mmcc007, thank you for your reply.
Solving the adb error version problem, now I am able to run correctly the screenshots. The "only" problem (surely due to the flutter driver bug) il that all the screens are in the main language and are not localized...

:(

[mmcc007]

Glad you were able to make progress with the adb version number.

Until such time as the flutter driver bug is resolved (or a workaround is found), unfortunately, it will not be possible to make localized screenshots.

Thank you for your feedback. Let me know if you run into any other problems.

[Alecsplus]

Thanks to you for your job, for the moment I will manually change the language on the device...

Bye.
