Resolving Localization Issues on Xbox for UWP Apps

When developing Universal Windows Platform (UWP) applications, localization is an important aspect that ensures your app caters to users from different regions and languages. However, issues may arise, especially when some users face difficulties that seemingly others don’t. One common problem developers encounter is related to localization on Xbox for German users, which we will explore in this guide.

Understanding the Problem

In this case, a developer reported that a small number of users, specifically those with German Xbox consoles, were facing an error when trying to load a JSON file during the application startup. This issue does not affect English users, and the developer was even unable to replicate the problem themselves.

Here’s a summary of the issue:

Error Encountered: The specific error message is "Element nicht gefunden," translating to "Element not found," which points to an issue with locating the file.

UWP Localization Structure: The developer organized their JSON files within language-specific folders:

\Assets\Content\language-de\MyData.json

\Assets\Content\language-en\MyData.json

Failed Attempt to Resolve: Even after reinstalling the app, the error persisted, suggesting that the problem was not related to installation or timing.

Analyzing the Likely Cause of the Issue

Given that it only affects German users, the problem likely lies in UWP’s localization mechanisms. While string localization worked without any issues, accessing resources from specific folders for localized content may not perform as expected on the Xbox platform, particularly for subsets of users.

Implementing a Workaround

Upon investigation, the developer found that they needed to implement their own logic to handle file selection, bypassing Microsoft’s default resource manager. Here’s how:

Specify Default Language File:
The developer initially set the URI for the English JSON file to be loaded.

Detect User Language:
They then retrieved the primary language preference of the user using the GlobalizationPreferences.Languages method.

Adapt File Selection Logic:
The file selection logic was adjusted to choose the German JSON file when the primary user language starts with “de” (for German).

Here’s a simplified version of the implemented code:

Conclusion

Localization issues can be tricky, especially when they occur for only a subset of users. By understanding the underlying cause and implementing a custom solution, the developer was able to ensure that users receive the appropriate localized content regardless of the localization difficulties presented by the Xbox platform.

If you encounter a similar issue, consider utilizing a custom logic approach to file selection based on user language preferences. This allows for flexibility and better handling of localization, ultimately enhancing the user experience across diverse regions.
