UI shows incorrect language

[ghost]

UI shows incorrect language in some cases.

Language settings:

• zh-TW: It shows the en language
• zh-HK: It shows the zh language

Technical information

• Device: ASUS Zenfone 6 (2019)
• OS: OmniROM 13
• OpenTracks version: v4.3.0, v4.3.1

IIRC that is the default behavior for missing translations in the regional specific locales.
First check zh-tw, then zh and then fallback to default (on Android this is en-us).

[ghost]

I note an untranslatable string named settings_layout_reset_key was translated in values-zh-rTW/strings.xml.
Is this the reason?

[dennisguse]

Actually, those should not be translated as they are purely technical. I will remove these translations.

[dennisguse]

Since you are on Android 13, how do you set the language?

PS/ settings_layout_reset_key is now in the correct file and cannot be translated anymore.

[ghost]

To set the language as zh-TW:

1. Going to "App info\Language" on OpenTracks.
2. Choose "中文 (台灣)", that is "Chinese (Taiwan)".

[ghost]

This issue started in v4.3.0.
In the old version 4.2.2, I got the correct language that same the system setting.

Btw, I saw settings_layout_reset_key on Weblate is still translated.

@elastic-rock this seems to be an effect of #1468.
Any ideas?

I confirm that I am alive and know about it, but I unfortunately had not the time to do it yet. I shall do it in a week max.

#1540 (comment)

[dennisguse]

@nthtimes could you check that this fixing your issue?
Nightly is already available and F-Droid might take some days as usual.

Now, it is correctly shows my language by system or manually specify.
But I found that all the regional option are getting the same translation, the Traditional Chinese (Hong Kong) seems to show zh-TW translation.

[dennisguse]

So, now it gets dirty.

I did some digging into when things started going wrong.

I compiled the APK for different versions and checked the included locales resources.asc/strings

• v4.3.4 does include 92 locales (no country-specific locales)
• v4.3.4 as deployed via PlayStore includes 91 locales: af, am, ar, as, az, be, bg, bn, bs, ca, cs, da, de, el, en_001, en_AU, en_CA, en_GB, en_IN, en_XC, es, es_419, es_US, et, eu, fa, fi, fr, fr_CA, fr_CH, ga, gl, gu, hi, hr, hu, hy, in, is, it, iw, ja, ka, kk, km, kn, ko, ky, lo, lt, lv, mk, ml, mn, mo, mr, ms, my, nb, ne, nl, or, pa, pl, pt, pt_BR, pt_PT, ro, ru, si, sk, sl, sq, sr, sr_Latn, sv, sw, ta, te, th, tl, tr, uk, ur, uz, vi, zh, zh_CN, zh_HK, zh_TW, zu
• v4.3.0 does include 44 locales (no country-specific locales)
• v4.3.0 (with manually naming all country-specific locales): these get included into resources.asc/strings
• v4.2.2 does include 92 locales (everything is included)

In the repo, we have 54 locales...

So, all the configuration for Android 13's per app language support (included in v4.3.0) some leads to omit locales (especially country-specific locales).
Autogenerating these config files as it is done in v4.3.4 (Android build tools 8.1.0) seems to work.

[dennisguse]

... but all that does not explain why the wrong regional locale is shown now.

[dennisguse]

@nthtimes could you check if this is still broken for you using the v4.3.5?

[ghost]

This is still broken in the v4.3.5.
I did try different region locale (they are zh_HK, zh_TW), and still getting same translation.

[dennisguse]

I just tested this using an Android 13 emulator and replaced zh, zh_HK, and zh_TW with a locale I can distinguish.
When doing this I get three different localizations.

The regions I get shown are these (screenshot below).
I translated the screenshot using Google Translate and all looks good.

Don't really know what else to test :/

[ghost]

After changing into the zh_hk translation, it seems good, but not.
I think I got the zh_tw translation, because the zh_hk translation has no any the translated strings in About OpenTracks.

[dennisguse]

In Weblate, we have three flavors of Chinese:

• https://hosted.weblate.org/projects/opentracks/opentracks-src-main-res-values-strings-xml-main/zh_Hant/#information mapped to zh
• https://hosted.weblate.org/projects/opentracks/opentracks-src-main-res-values-strings-xml-main/zh_Hant_HK/#information mapped to zh-rHK
• https://hosted.weblate.org/projects/opentracks/opentracks-src-main-res-values-strings-xml-main/zh_Hans/#information mapped to zh-rTW (Taiwan)

First, I don't know why Weblate is mapping zh_Hans to zh-rTW.
Second, Android will use zh aka zh_Hant as fallback if a translation is zh-rHK is missing.
Some more infos here: https://developer.android.com/guide/topics/resources/multilingual-support

I am really at a loss here on how to continue.
