+# Localization
+
+The Open Video UI for Android can be localized to different languages,
+enabling you to reach audiences from different regions of the world.
+
+Localization works
+by [providing alternative resources](https://developer.android.com/guide/topics/resources/providing-resources#AlternativeResources)
+in one or more languages. You can choose to [change the text of the default language](#change-default-language)
+to target a single audience, or [add alternative languages](#add-alternative-languages) to target many audiences.
+
+## Changing the default language {#change-default-language}
+
+By default, the Open Video UI ships with English texts only. If your app targets a non-English speaking audience,
+you can override these texts with translations for another language.
+
+1. Copy the English string resources
+   from [`res/values/strings.xml`](https://github.com/THEOplayer/android-ui/blob/main/ui/src/main/res/values/strings.xml)
+   to your app's resources for the default locale (i.e. `res/values/strings.xml`).
+2. Change the resource values to the translated texts.
+   For example, to change the title of the "Language" menu, you would change the contents
+   of the `theoplayer_ui_menu_language` resource:
+
+   ```xml title="res/values/strings.xml"
+   <resources>
+     <string name="theoplayer_ui_menu_language">Langue</string> <!-- translated to French -->
+   </resources>
+   ```
+
+   :::tip
+   You can also use
+   the [Translations Editor in Android Studio](https://developer.android.com/studio/write/translations-editor)
+   to edit these values.
+   :::
+
+3. Build and run your app. The translated texts should now appear in your player UI.
+
+## Add alternative languages {#add-alternative-languages}
+
+If your app targets many audiences speaking different languages, you can add multiple translations using
+locale-specific resources.
+
+1. Copy the English string resources
+   from [`res/values/strings.xml`](https://github.com/THEOplayer/android-ui/blob/main/ui/src/main/res/values/strings.xml)
+   to your app's resources for the default locale (i.e. `res/values/strings.xml`).
+2. Add a new string resources file for a new locale.
+   For example, for French, create the file: `res/values-fr/strings.xml`.
+3. Add translated versions for each English string resource to the new resources file.
+   For example, to translate the title of the "Language" menu, you would add an entry for `theoplayer_ui_menu_language`:
+   ```xml title="res/values-fr/strings.xml"
+   <resources>
+     <string name="theoplayer_ui_menu_language">Langue</string>
+   </resources>
+   ```
+
+## Remarks
+
+### Update translations when upgrading Open Video UI
+
+Newer versions of the Open Video UI for Android may add new string resources that need to be translated.
+
+When using custom translations in your app, we recommend pinning the `com.theoplayer.android-ui:android-ui` dependency
+in your app's `build.gradle` to a specific version. Avoid using `+` in the dependency's version range.
+
+```groovy title="build.gradle"
+dependencies {
+    implementation "com.theoplayer.android-ui:android-ui:1.9.0"
+}
+```
+
+When you decide to upgrade Open Video UI to the latest version, make sure to also update your translations.
+Check the history for [`res/values/strings.xml`](https://github.com/THEOplayer/android-ui/commits/main/ui/src/main/res/values/strings.xml)
+to see whether any string resources were added or changed since the previous version.
