# Localization for Xamarin viewer tools

Learn how to localize Xamarin.Android and Xamarin.iOS Tools for different languages. Follow step-by-step instructions to add translations and create C# NuGet packages for your applications. The Apryse

Localization for Tools library follows each platform's convention.

## Xamarin.Android Tools localization

You can put your translation `strings.xml` into `Resources/values-xx` directory of your application, i.e. `values-fr` for French.

See available languages here: [Localization on Android](/android/viewer/localization.md).

## Xamarin.iOS Tools localization

1. [Download the the native SDK](/ios/get-started/download.md).
2. Navigate into `./Lib/Tools/src/PDFViewCtrlTools/Tools/en.lproj` to find the example `Localizable.strings` file that contains translation information for the Tools source code. Rename this file to `PTLocalizable.strings`
3. Create a directory called `<language code>.lproj` within your project resources directory and place the `PTLocalizable.strings` file from Step 2 in the directory. For a list of language codes supported by Apple, please refer to the [Apple documentation](https://developer.apple.com/library/archive/MacOSX/Conceptual/BPInternational/LanguageandLocaleIDs/LanguageandLocaleIDs.html).
4. Add the translations into the `PTLocalizable.strings` file.

### Localization when compiling Tools from source (deprecated)

{% hint style="warning" %}
**Warning**

This method only applies to versions of the SDK prior to v6.10.2.

This method is not recommended as it involves editing the `Tools.framework` strings file directly which will create a requirement to manually merge strings files when updating to new versions of `Tools.framework`.
{% endhint %}

1. Follow the [native localization guide](/ios/viewer/localization.md#localization-when-compiling-tools-from-source).
2. Follow the [Tools binding guide](/xamarin/learn-more/objc-ios.md) to create the C# NuGet packages.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.apryse.com/xamarin/viewer/localization.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
