How Do I Localize My Android App?

Android, Android Apps

Are you planning to expand your app’s reach beyond your native language? If yes, then you need to localize your Android app.

Localization is the process of adapting an application for specific locales or languages. With localization, you can provide a more personalized and engaging user experience to your users.

In this tutorial, we will discuss the steps involved in localizing an Android app. Let’s get started!

Step 1: Plan Your Localization Strategy

Before beginning the localization process, it is essential to plan a localization strategy. You need to decide which language(s) you want to support and prioritize them based on the Target audience and market demand.

Step 2: Extract Text for Localization

The next step involves extracting the text that needs to be translated from your app’s source code. You can use Android Studio’s built-in tools or third-party libraries like gettext and i18n for this purpose.

Step 3: Translate the Text

Once you have extracted the text, it’s time to translate it into different languages. You can hire a professional translation service or use online translation tools like Google Translate. However, it’s important to note that automated translations are not always accurate and may result in errors or misinterpretations.

Step 4: Implement Localization in Your App

After translating the text, you need to implement localization in your app by creating resource files for each supported language. In Android, resource files are located under the res/ directory of your project.

You need to create separate directories for each language with a two-letter ISO 639-1 language code suffix (e.g., values-es for Spanish). Within these directories, create XML files with translated strings using the tag.

Here’s an example:

  • English: Hello, World!
  • Spanish: ¡Hola, mundo!

You can access these translated strings in your app’s code by using the getString() method, passing the string resource ID as an argument.

Step 5: Test and Verify Localization

Finally, you need to test and verify your app’s localization. You can use Android emulator or physical devices to test your app in different languages. Make sure that all the translated text is displaying correctly and there are no layout issues or encoding errors.


In this tutorial, we have discussed the steps involved in localizing an Android app. By following these steps, you can provide a more personalized and engaging user experience to your users in different languages. Remember to plan your localization strategy carefully and always test and verify your app before releasing it to the market.
