調査の方向性

壊れている文字列は owncloudApp/src/main/res/values-ug/strings.xml（Issueに記載された55個のキー）と、media_notif_ticker 用の values-sv/strings.xml にあります。文字列の書式を確認するため、まず FileListAdapter.kt（file_list__footer__files）と DrawerActivity.kt（drawer_quota）を見てください。翻訳された各文字列が英語のプレースホルダー（%1$s、%1$d、%s）を正確に保持し、ウイグル語とスウェーデン語のファイルが例外なく書式化されれば完了です。Issueによると修正は Transifex で行うべきとのことなので、リポジトリを直接編集する前にメンテナーに確認してください。

説明

Actual behaviour

In the Uyghur translation (owncloudApp/src/main/res/values-ug/strings.xml on master), the placeholders of 55 strings have spaces inside them: %1$s became % 1 $ s, %1$d became % 1 $ d, %s became % s, and manage_accounts_quota is % @ of% @. Android formats these strings with java.util.Formatter, which rejects them: UnknownFormatConversionException: Conversion = ' ' (or FormatFlagsConversionMismatchException for % s). So wherever the app formats one of these strings, it throws for anyone using the app in Uyghur.

Two of them are on main screens:

  • File list footer: FileListAdapter.kt calls context.getString(R.string.file_list__footer__files, filesCount). The Uyghur text is % 1 $ d ھۆججەتلەر. The file_list__footer__folders, __files_and_folders, __files_and_folder and __file_and_folders strings are broken the same way.
  • Drawer quota: DrawerActivity.kt runs String.format(getString(R.string.drawer_quota), used, total, relative). The Uyghur text is ئىشلىتىلگەن% 2 $ s نىڭ% 1 $ s (% 3 $ s %%). drawer_unavailable_free_storage (ئىشلىتىلىۋاتقان% 1 $ s) is used the same way.

Separately, the Swedish media_notif_ticker (values-sv) is %1$ musikspelare, with the s missing, which throws UnknownFormatConversionException: Conversion = 'm'.

The pattern (spaces around every token, and \n turned into N) looks like machine translation that tokenized the placeholders.

Expected behaviour

Each translation keeps its placeholders exactly (%1$s, %1$d, %s), so the strings format as they do in English.

Steps to reproduce

I have not run this on a device. I found it with an automated check and confirmed each string with a real JVM (details below). A minimal check is:

String.format("% 1 $ d ھۆججەتلەر", 3);
// java.util.UnknownFormatConversionException: Conversion = ' '

In the app, this should happen when you:

  1. Set the device language to Uyghur (ئۇيغۇرچە).
  2. Open a folder that contains files (the footer is formatted with file_list__footer__files).
  3. Open the drawer (the quota line is formatted with drawer_quota).

This isn't server-related.

Environment data

Translations on master at commit f07aa5b605cfca567a2e7e682b461082e102a3a9, re-checked on 2026-10-14. This shouldn't depend on the device: since Android 7, java.util.Formatter is OpenJDK's code, which throws on these specifiers.

Suggested fix

Translations come from Transifex, so the fix belongs there:

  • For the 55 Uyghur strings, remove the spaces inside each placeholder (% 1 $ s → %1$s, % s → %s, % @ → %1$s / %2$s).
  • For the Swedish media_notif_ticker, use %1$s musikspelare.

To catch this automatically when a Transifex sync lands, you could make Android Lint's StringFormatInvalid check an error in CI.

All 55 affected Uyghur keys

How this was found

I'm MV2 of Munim, Inc. This came out of a census of translations that crash String.format in open-source Android apps listed on F-Droid. Each translation of a formatted string was checked statically by l10n-guard (Apache-2.0), then formatted with OpenJDK 21's java.util.Formatter to confirm it throws. The check and this report were made with AI agents. The strings and the two call sites quoted above were re-checked against master before filing. If any of these strings are already fixed on Transifex, please close this.
