Published Internal Testing Expo App Name is Not Localized

[Dulatech]

I currently have a standalone android app built using 'expo build:android'. However the app name is not localized when published through the Google Play Console as an internal testing app. I have followed all of the instructions in the README.

I ran 'expo prebuild' without any issues and was able to generate the /values and /values-fr folders with the correct strings in the strings.xml files inside each respective folder.

My app.config.js file has the following structure:

import withAndroidLocalizedName from '@mmomtchev/expo-android-localized-app-name';

export default {
  name: "my app",
  slug: "slug",
  version: "1.0.0",
  platforms: ["ios", "android"],
  locales: {
    fr: "./permissions/french.json"
  },
  assetBundlePatterns: ["**/*"],
  ios: {
    infoPlist: {
      CFBundleAllowMixedLocalizations: true
    },
  },
  web: {
    favicon: "./assets/favicon.png"
  },
  plugins: [["test-plugin"], [withAndroidLocalizedName]],
  ...
}

My french.json file has the following structure:

{
  "CFBundleDisplayName": "mon app",
  "app_name": "mon app",
}

Please advise, any help would be appreciated.

Your configuration looks ok, do you get any errors when building? Also, can you run expo prebuild and post the contents of android/app/src/main/res/values-fr/strings.xml?

[Dulatech]

I had no errors when building. When I ran expo prebuild the android/app/src/main/res/values-fr/strings.xml had the following content:

<resources>
    <string name="app_name">mon app</string>
</resources>

[mmomtchev]

Do you also have android/app/src/main/res/values/strings.xml?

[Dulatech]

Yes this is my android/app/src/main/res/values/strings.xml file

<resources>
  <string name="app_name">my app</string>
  <string name="expo_splash_screen_resize_mode" translatable="false">contain</string>
  <string name="expo_splash_screen_status_bar_translucent" translatable="false">false</string>
</resources>

[mmomtchev]

Everything looks ok.
Do you have any other plugins? Can you also post your AndroidManifest.xml?

[Dulatech]

I had one other plugin, which I removed. I built the app again without issue.

Here is my AndroidManifest.xml:

I see that you are in Canada, can you try this:
https://stackoverflow.com/questions/6676393/localization-codes-does-not-work

[Dulatech]

I added the following locales to my app.config.js.

locales: {
      fr: "./permissions/french.json",
      fr-rFR: "./permissions/french.json",
      fr-rCA: "./permissions/french.json"
},

I was able to generate values folders when running expo prebuild, i.e android/app/src/main/res/values-fr-rCA/strings.xml, each containing the following:

<resources>
    <string name="app_name">mon app</string>
</resources>

The published app name is still not translated however when switching my language to French (Canada) on my Android device.

[mmomtchev]

Can you also add an explicit English language translation different from the default one and tell me if you get the default one or the English one when you switch to English?
