OneSignal Huawei Flutter Setup Guide

1. Flutter OneSignal SDK setup

• Follow the Android setup instructions here: OneSignal Setup

2. Huawei Setup

• 2.1 Device and Android SDK Setup
• 2.2 App Configuration
• 2.3 Add dependencies to Flutter android project
  • In the case Flutter plugin is going to be used (see step 3), then this step can be skipped.
  • Under project build.gradle add the following

buildscript {
    repositories {
        google()
        jcenter()
        maven { url 'http://developer.huawei.com/repo/' }
    }

    dependencies {
        ...
        classpath 'com.huawei.agconnect:agcp:1.2.1.301'
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        maven { url 'http://developer.huawei.com/repo/' }
    }
}

• Under app build.gradle add the following

dependencies {
    ...
    implementation 'com.huawei.hms:push:4.0.3.300'
}

apply plugin: 'com.huawei.agconnect'

3. Flutter Huawei Plugin setup (Optional)

OneSignal does not require the Flutter Huawei plugin and in most cases you can omit this. However, if you need specific Huawei features in Flutter see Integrating Flutter HMS Push Kit Module

• 3.1 When following the plugin setup, after downloading the plugin remove the FlutterHMSMessageService from the downloaded plugin's AndroidManifest.xml file under the android package.

4. Huawei Location Service (Optional)

• 4.1 Add implementation 'com.huawei.hms:location:<HUAWEI HMS VERSION #> to your app build.gradle's dependencies section.
• 4.2 Make sure to also add the location permission to your AndroidManifest.xml if you don't have this already

dependencies {
    ...
    implementation 'com.huawei.hms:location:4.0.0.300'
}

Huawei Flutter Sample

This is an example Flutter project integrating the Huawei Flutter Plugin.

Huawei Error Codes

• HMS error code reference to help debug logs and successfully integrate HMS Core SDK with the OneSignal SDK.

Keystore Signature

• Huawei Signing Certificate Usage
  • You may need to create a debug or release keystore signature (choose the correct app build path, debug or release) so that a 6003 error is avoided when registering for Huawei pushToken with the OneSignal SDK.
