A modern programming language that makes developers happier.

kotlinlang

Have any of you ever changed the language in runtime while running espresso tests? We are trying to automate the screenshot generation for our app in all the available languages, yet local changes are not reflected in the UI. Ideas?

Have you had a look at this article ?<https://proandroiddev.com/change-language-programmatically-at-runtime-on-android-5e6bc15c758>

It is currently (android &gt;= 26) not possible. Try this

Hi guys, thanks, tried both but no luck. It's impressive how this turned to be difficult to achieve :disappointed:

Actually the only reliable and working way I found: <https://play.google.com/store/apps/details?id=net.sanapeli.adbchangelanguage&amp;hl=en_US>

with it I can mix my Espresso tests with adb scripts and get all possible languages :slightly_smiling_face:

You asked for a solution from your espresso tests not for adb commands :smile:

yes, yet, from espresso it never worked, thanks anyway
