The **Equativ Display SDK** provides a convenient way to add languages or change the strings used by the ad player on supported languages.

---

## Supported Languages

By default, the **Equativ Display SDK** is shipped with the following languages:
- English
- French

## Adding & changing localization

The **Equativ Display SDK** relies on the localization mecanism provided by Android platform, using xml files located in the `res` folder of the AAR library file.

To change the existing strings or to add new languages, you need to:

1. **Create a `strings_equativ.xml` file** containing all keys listed in the [next section](https://help-display-sdk.equativ.com/android/localization.html#strings) with their value in the language you want to add/modify.
2. **Add this new file to the resource folder** corresponding to the desired language of your application project.

   For instance, if you want to change french strings, you will add the `strings_equativ.xml` to the `res/value_fr`.

   Please refer to Android plaftorm documentation for further information about normalized folder names for all languages

All strings defined in XML files of your application will override **Equativ Display SDK** strings defined in a file of the same name

## Localized strings

Here is the XML content containing all keys/values used to localized the **Equativ Display SDK** in english.

Those values are the labels of the native video player interface used to display video ads.

```xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="sas_post_video_layout_replay_button_text">replay</string>
    <string name="sas_post_video_layout_clickthrough_button_text">more info</string>
</resources>
```
