[Huawei Developers] HMS Community:
Overview

In this article, I will create a Courier android application using Kotlin in which I will integrate HMS Core kits such as HMS Account, Push, CloudDB, AuthService, Push Kit Uplink Message, Location and Map Kit.

We have integrated HMS Account and AuthService Kit in part-, Push Notification Using HMS Push Kit in Part-2, Cloud DB Kit in Part-3 and Huawei Client Push integration in Part4 of this series. Kindly go through the link below-

Part-1 https://forums.developer.huawei.com/forumPortal/en/topic/0202841957497640128

Part-2 https://forums.developer.huawei.com/forumPortal/en/topic/0201847982965230092

part-3 https://forums.developer.huawei.com/forumPortal/en/topic/0201854022878900124?fid=0101187876626530001

App will make use of android MVVM clean architecture using Jetpack components such as DataBinding, AndroidViewModel, Observer, LiveData and much more.

In this article, we are going to implement DataBinding using Observable pattern.

Map Kit Introduction

Map Kit covers map data of more than 200 countries and regions, and supports over 70 languages. User can easily integrate map-based functions into your apps using SDK. It optimizes and enriches the map detail display capability. Map Kit supports gestures including zoom, rotation, moving and tilt gestures to ensure smooth interaction experience.

Location Kit introduction

Location Kit combines the GPS, Wi-Fi and base station location functionalities in your app to build up global positioning capabilities, allows to provide flexible location-based services targeted at users around globally. Currently, it provides three main capabilities: fused location, activity identification and geo-fence. You can call one or more of these capabilities as required.

Prerequisite

Huawei Phone EMUI 3.0 or later.

Non-Huawei phones Android 4.4 or later (API level 19 or higher).

HMS Core APK 4.0.0.300 or later

Android Studio

AppGallery Account

App Gallery Integration process

Sign In and Create or Choose a project on AppGallery Connect portal.

Navigate to Project settings and download the configuration file.

Navigate to General Information, and then provide Data Storage location.

App Development

Add Required Dependencies:

Launch Android studio and create a new project. Once the project is ready.

Navigate to the Gradle scripts folder and open build.gradle (project: app).

ext.kotlin_version = "1.4.21"
repositories {
google()
jcenter()
maven {url 'https://developer.huawei.com/repo/'}

classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath 'com.huawei.agconnect:agcp:1.4.2.300'
Add following dependency for HMS Loaction and Map Kits

// Huawei Map
implementation 'com.huawei.hms:maps:6.2.0.301'
// Huawei Location Kit
implementation 'com.huawei.hms:location:6.2.0.300'

App Build Result

Tips and Tricks

Set minSDK version to 24 or later, otherwise you will get AndriodManifest merge issue.

Make sure you have added the agconnect-services.json file to app folder.

Make sure you have added SHA-256 fingerprint without fail.

Make sure all the dependencies are added properly.

Conclusion

In this article, we have learned how to integrate HMS Account, Push, CloudDB, AuthService, Push Kit Uplink Message, Location and Map Kit in Android application. After completely read this article user can easily implement Location and Map Kit in the Courier android application using Kotlin.

Thanks for reading this article. Be sure to like and comment to this article, if you found it helpful. It means a lot to me.
