Translate Android strings.xml with AI

Translate your Android app’s strings.xml file in minutes with AI that outperforms human translators. Try it free for 30 days — no credit card required. Choose your target language, add a short description of your app, and upload your strings.xml file to get a fully translated XML file ready to download.

Translating Your Application for the First Time with PTC

Private Translation Cloud (PTC) is an AI translator optimized for software. It translates your resource files into 33 languages in minutes, with human-level quality at machine speed and cost. You can try PTC free for the first 30 days.

Step 1

Sign Up for a 30-Day Free Trial with PTC

Sign up for a 30-day free trial — no credit card required and no limitations.

During the trial period, you can translate any resource file into any language. You can then download and use the translations. After the trial ends, you are welcome to continue using PTC by upgrading your account, but there is no obligation.

Step 2

Choose Languages to Translate To

Select any of the supported languages. PTC offers context-aware translation into more than 33 languages.

Step 3

Tell PTC About Your App

Tell PTC your app’s name, what it does, and who it is for. This context helps PTC choose the right tone, terminology, and phrasing so the translations feel natural in each language.

Step 4

Upload Your Resource File

The resource file you need to translate is typically located in /app/src/main/res/values/strings.xml inside your project in Android Studio. Upload this file to PTC.

If you already have some translations, you can upload them as well. However, for best results, we recommend translating from scratch, as PTC generally provides better quality than most human translators.

Step 5

View the Translations in PTC and Download The Translated strings.xml

PTC may take a few minutes to translate your resource file. Once the translation is complete, you can view the results in the Translations tab.

When you’re ready, you can go to the Resource Files tab and download the fully translated resource files for use in Android Studio.

To use the translations in your project, create localized values folders. For example:

  • /app/src/main/res/values-es/strings.xml (for Spanish)
  • /app/src/main/res/values-de/strings.xml (for German)

Step 6

Rebuild Your App To Display the Available Languages

Once your translated strings.xml files are in your Git repository, rebuild your app. Android will automatically display the correct language based on the user’s device settings. No additional changes are needed in your code.

Translating Your App’s “Description” With PTC

The description is the text that appears in the Google Play Store for your app. To get the full benefits of localization, you should translate this content as well.

In PTC, go to TranslationsPaste to translate and add your app’s short and long description texts.

Since these texts are not part of the strings.xml resource file, you’ll need to manually copy and paste the translated versions into the Google Play Console:

  1. Go to Google Play Console → Store Presence → Main Store Listing → Translations
  2. Add your translated short and long descriptions for each language
  3. Save and publish

This makes your app discoverable and appealing to users in their own language.

Automating the Translation Process

You don’t need to upload strings.xml manually every time something changes. PTC can automatically monitor updates to your resource file and keep your translations up to date.

Option 1

Integrate PTC Into Your Git Repository

Connect your GitHub, GitLab, or Bitbucket repository to PTC. Specify which branches to monitor. When a change is detected in the strings.xml file in any of those branches, PTC will automatically translate the updated content and send the translations back via a merge request.

To use Git integration, PTC requires read and write access to your repository. This allows it to retrieve the resource file and push translated files. You can grant access using OAuth or a personal access token.

Option 2

Integrate PTC Into Your CI Process

If you prefer not to give PTC access to your repository, you can still automate translation by connecting your CI workflow to the PTC API. Your CI process can notify PTC when a new version of the strings.xml file is available. PTC will then process the translation and notify your CI when the translated files are ready to download.

Optimizing Your strings.xml File for Translation

Not all resource files are fully optimized for translation. Use the following checklist to ensure your strings.xml file is fully optimized so translations appear fluent and natural across languages.

Include All User-Facing Text in strings.xml

Store all user-facing string in your strings.xml file. This lets PTC extract all texts and translate them accurately.

Hardcoded strings won’t be extracted by PTC, so they’ll stay in English and won’t appear translated in your app.

Use Placeholders for Dynamic Texts

When displaying dynamic content like names or numbers, use placeholders such as %s or %d. Avoid breaking the sentence into multiple strings or using string concatenation.

Splitting a sentence may result in unnatural or incorrect translations, as grammar and word order vary between languages.

Use UTF-8 Encoding

Make sure your strings.xml file is saved in UTF-8 to support special characters, accents, and non-Latin alphabets. Android Studio does this by default, but it’s good to verify this if you edit the file outside the IDE.

Use PTC to translate other projects

PTC isn’t just for Android — it supports other resource file formats like iOS .strings, JSON, and more.
