Technical details

• Device name: Google Pixel 3a emulator
• Android version: 11
• First reported on App version: 2.7.1
• Confirmed still present on App version: 2.29.x

Describe the bug

If the device language is changed, the Rapid Test Profile input view does not refresh the field prompts.

Steps to reproduce the issue

(Updated for 2.29.x on Pixel 3a API 33 (Android 13))

1. Settings > System > Languages and input > Languages, set English (United Kingdom)
2. In CWA Status screen, tap "Manage Your Tests"
3. Tap "Rapid Test Profile" (tap Continue if necessary), tap "+ Rapid Test Profiles"
4. Note that all text is in English
5. Without closing CWA, repeat step 1 and change preferred language to Deutsch (Deutschland)
6. View CWA again and note the mixture of languages
7. Tap back arrow
8. Tap "+ Schnelltest-Profil"
9. Now all text, including the field prompts are in German

App at step 6:

Expected behavior

Android apps are expected to immediately respond to language changes. At step 6 in the steps to reproduce, the app should show only German text as in the following screen shot.

Additional information

Thanks to feedback from @PhilippNowak96 who identified that this is an issue of TextInputLayout in the Material Components, see: issue material-components/material-components-android#2075.

The Material Components issue is now closed through material-components/material-components-android@051410b. Material Components for Android 1.7.0 is supposed to fix this issue.

@MikeMcC399 Thanks. Internal Tracking ID: EXPOSUREAPP-9151

@Ein-Tim Actually I can observe something similar on iOS. The country list when checking a DCC is in English, although the phone locale is set to DE. No way to get it to German back. iPhone 6s.

That is an entirely different problem. Perhaps you should submit an issue in the iOS repository? It doesn't belong here at all. I checked by the way on Android, and Android correctly provides the list of countries in German, but this is not related to the Rapid Test Profile in any way.

@dsarkar

I will open an issue regarding this!

This seems to be an issue of TextInputLayout in the Material Components, see: material-components/material-components-android#2075

@PhilippNowak96

Thanks for uncovering that issue (material-components/material-components-android#2075)!

The standard Android elements TextView and Button refresh correctly. Everything else (which doesn't refresh correctly) is from com.google.android.material.textfield 😞.

Edit: Android issue material-components/material-components-android#2075 is open with label "Needs investigation".
It says there that the issue was introduced with 1.3.0-alpha03.

CWA is using com.google.android.material:material:1.3.0 so that fits.

cwa-app-android/Corona-Warn-App/build.gradle

Line 332 in 9d6525b

implementation 'com.google.android.material:material:1.3.0'

• The underlying issue [com.google.android.material.textfield.TextInputLayout] text language is not updated after locale update and activity recreate material-components/material-components-android#2075 still has the label "Needs Investigation"
• This issue is a corner case because most users will not be changing the phone locale with CWA active

Closing as low impact and unsolved, due to the external component Material Components for Android (MDC-Android).

@MikeMcC399 thanks for your comment, forwarded to internal ticket.

[MikeMcC399]

material-components/material-components-android#2075 is now closed with a fix, however there is not yet a new release of Material Components for Android (MDC-Android) containing this fix.

The upcoming CWA release 2.24.x is configured with
implementation 'com.google.android.material:material:1.6.0'

Judging by the progress in the https://github.com/material-components/material-components-android/ repository, the fix looks like it might be released with a material 1.7.x version.

[MikeMcC399]

Material Components for Android 1.7.0-alpha03 addresses this issue.

1.7.0-alpha03 requires a minimum compileSdkVersion and targetSdkVersion version 32 which makes it currently incompatible with release/2.25.x. The CWA Android 2.25.x branch is currently on version 31 of compileSdkVersion and targetSdkVersion. The app builds successfully after updating to version 32.

Updating
implementation 'com.google.android.material:material:1.6.0' to
implementation 'com.google.android.material:material:1.7.0-alpha03'
however produces fatal build errors, which would need investigation.

Edit: Superseded by 1.7.0-rc01

@MikeMcC399 Thanks, forwarded to internal ticket.

[MikeMcC399]

Re-opening this issue, since it still occurs and an official fix is now available.

Material Components for Android (MDC-Android) has now made Release 1.7.0 available which enables this CWA issue to be resolved without using an alpha or rc release. Fixed through commit material-components/material-components-android@051410b.

Perhaps there is scope in a future CWA version to incorporate this fix?

The official prerequisites however still include:
compileSdkVersion and targetSdkVersion minimum 32

This is not currently met by the 2.29 branch:

cwa-app-android/Corona-Warn-App/build.gradle

Lines 30 to 35 in f13b188

	compileSdkVersion 31
	buildToolsVersion "32.0.0"
	defaultConfig {
	applicationId 'de.rki.coronawarnapp'
	minSdkVersion 23
	targetSdkVersion 31

Good morning @MikeMcC399! I will re-open the internal ticket and forward your findings! Thanks!

@MikeMcC399 FYI PR #5668

[MikeMcC399]

• I tested PR Rapid Test Profile shows mixed languages after change in locale (EXPOSUREAPP-9151) #5668 and it solves the issue 👍🏻

[MikeMcC399]

Fix is included in pre-release version v2.29.0-rc.0.

The label Fix 3.0 Fix is planned for 3.0 has been edited, however the text hasn't been changed, so it is out of sync.

Please check and correct in the https://github.com/corona-warn-app/cwa-app-android/labels list.

[MikeMcC399]

The issue has been fixed and is awaiting release.

According to BMG on Twitter CWA 3.0 has a planned release date of Wednesday, Jan 18, 2023. Since this is an edge case it won't be noticed by most users, so I am closing it in advance of the release.

@larswmh Thanks for fixing the label text.
