Beginner: Huawei App Messaging Unity Game Development - Huawei Developers

Introduction
You can use App Messaging of AppGallery Connect to subscribe and send relevant messages to target active users of your app to encourage them to use key app functions. For example, you can send in-app messages to encourage users to subscribe certain products, provide tips on passing a game level or recommend activities of a restaurant.
App Messaging allows you to customize our messages look and the way they will be sent, and define events for triggering message sending to your users at the right moment.
AG Connect supports three types of messages as follows:
1. Pop-up message
2. Image message
3. Banner message

Click CREATE, as follows:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

2. Click Asset Store, search Huawei HMS Core App Services and click Import, as follows.
3. Once import is successful, verify directory in Assets> Huawei HMS Core App Services path, as follows.
4. Choose Edit > Project Settings > Player and edit the required options in Publishing Settings, as follows.
5. Generate a SHA-256 certificate fingerprint.
To generating SHA-256 certificate fingerprint use below command.
Code:
keytool -list -v -keystore D:\Unity\projects_unity\file_name.keystore -alias alias_name
6. Download agconnect-services.json and copy and paste to Assets > Plugins > Android, as follows.
7. Choose Project Settings > Player and update package name.
8. Open LauncherTemplate.gradle and add below line.
Code:
apply plugin: 'com.huawei.agconnect'
implementation 'com.huawei.hms:hianalytics:5.1.0.301'
implementation 'com.huawei.agconnect:agconnect-core:1.4.2.301'
9. Open AndroidManifest file and add below permissions.
Code:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
10. Open "baseProjectTemplate.gradle" and add lines, as follows.
Code:
classpath'com.huawei.agconnect:agcp:1.4.1.300'
maven {url 'https://developer.huawei.com/repo/'}
11. Open "mainTemplate.gradle" and add lines, as follows.
Code:
implementation 'com.huawei.agconnect:agconnect-core:1.4.2.301'
implementation 'com.huawei.hms:hianalytics:5.1.0.301'
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.huawei.agconnect:agconnect-appmessaging:1.4.1.300'
12. Enable debug mode use in cmd prompt [optional].
Code:
adb shell setprop debug.huawei.hms.analytics.app package_name
13. Configuring project in AGC
14. Create Scripts folder and create a class.
APPMessaging.cs
C#:
using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using HuaweiService;
using HuaweiService.appmessage;
using HuaweiService.analytic;
using HuaweiService.push;
using Exception = HuaweiService.Exception;
public class APPMessaging : MonoBehaviour
{
private HiAnalyticsInstance instance;
private AGConnectAppMessaging appMessaging;
private void Start()
{
instance = HiAnalytics.getInstance(new Context());
appMessaging = AGConnectAppMessaging.getInstance();
appMessaging.setFetchMessageEnable(true);
appMessaging.setDisplayEnable(true);
instance.setAnalyticsEnabled(true);
getAAID();
}
private void getAAID(){
// Task result = instance.getAAID();
Task id = HmsInstanceId.getInstance(new Context()).getAAID();
id.addOnSuccessListener(new HmsSuccessListener<AAIDResult>((aaidResult) =>
{
string aaId = aaidResult.getId();
Debug.Log("AAID==>> "+aaId);
})).addOnFailureListener(new HmsFailureListener((e) =>
{
Debug.Log("AAID==>> Failed");
}));
}
public delegate void SuccessCallBack<T>(T o);
public class HmsSuccessListener<T>:OnSuccessListener{
public SuccessCallBack<T> CallBack;
public HmsSuccessListener(SuccessCallBack<T> c){
CallBack = c;
}
public void onSuccess(T arg0)
{
if(CallBack != null)
{
CallBack.Invoke(arg0);
}
}
public override void onSuccess(AndroidJavaObject arg0){
if(CallBack !=null)
{
Type type = typeof(T);
IHmsBase ret = (IHmsBase)Activator.CreateInstance(type);
ret.obj = arg0;
CallBack.Invoke((T)ret);
}
}
}
public delegate void SuccessCallBack(AndroidJavaObject object);
public delegate void FailureCallBack(Exception e);
public class HmsFailureListener:OnFailureListener{
public FailureCallBack CallBack;
public HmsFailureListener(FailureCallBack c){
CallBack = c;
}
public override void onFailure(Exception arg0){
if(CallBack !=null){
CallBack.Invoke(arg0);
}
}
}
}
AndroidManifest.xml
Code:
<?xml version="1.0" encoding="utf-8"?>
<!-- GENERATED BY UNITY. REMOVE THIS COMMENT TO PREVENT OVERWRITING WHEN EXPORTING AGAIN-->
<manifest
