@armanatz/expo-hms-location

This Expo config plugin auto-configures @hmscore/react-native-hms-location so that is can be used inside an Expo application that uses Continuous Native Generation.

Compatibility

This plugin is currently only for Android and there are no plans to add iOS support at the moment. I am open to PRs however so feel free to create one if you need iOS support.

This plugin was written and tested against Expo SDK 51.

It goes without saying but this plugin cannot be used in an "Expo Go" app as it requires custom native code.

Prerequisites

Ensure that you have a Huawei AppGallery Connect account and have created an Android project in there before using this plugin.

This is needed because you will require the agconnect-services.json file associated to your project.

Installation

First install the base React Native HMS Location package:

npm install --save @hmscore/react-native-hms-location

Then install this plugin:

npx expo install @armanatz/expo-hms-location

Configuration

Add @armanatz/expo-hms-location to your app's Expo config file (app.json, or app.config.js).

The plugin exposes the following options:

Option	Type	Description
agConnectServicesFile	string	Path to your agconnect-services.json file.
isBackgroundLocationEnabled	boolean	(Optional) Enable location service in the background
enableBouncyCastleFix	boolean	(Optional) If you get errors related to org.bouncycastle (like when using expo-updates), then set this to true

!! IMPORTANT !!: The option agConnectServicesFile has to be provided, otherwise the prebuild will fail.

---

Example configuration:

"expo": {
  ...
  "plugins": [
      [
        "@armanatz/expo-hms-location",
        {
          "agConnectServicesFile": "./path/to/agconnect-services.json",
          "isBackgroundLocationEnabled": true,
          "enableBouncyCastleFix": true
        }
      ]
  ]
}

Post Configuration

After adding the plugin to your Expo config file, ensure you rebuild your app by running prebuild so that the plugin can apply its changes accordingly.

If all goes well, your app should now be able to use the @hmscore/react-native-hms-location package inside your Expo application.

Changes Made By This Plugin

1. Copies your agconnect-services.json file to the android/app directory
2. Extracts the App ID of your application from the agconnect-services.json
3. Sets extracted App ID in AndroidManifest.xml
4. Adds relevant location permissions in AndroidManifest.xml as per Huawei's docs
5. Adds the Huawei Developer Maven repo to the project's build.gradle file
6. Pins the Android Gradle Build Tools version to 8.6.0 (This is needed because the Huawei SDKs cause build errors without it)
7. Adds the Huawei AGCP SDK to the project's build.gradle file
8. Applies the Huawei AGConnect plugin inside the app's build.gradle file
9. Adds the Huawei Location Kit SDK to the app's build.gradle file
10. If enableBouncyCastleFix is set to true, will resolve org.bouncycastle dependency
