Overview
In this article, I will create a Doctor Consult Demo App along with the integration of Huawei Id, Map and Identity Kit. Which provides an easy interface to consult with doctor. Users can choose specific doctors and get the doctor details using Huawei User Address.
By reading this article, you'll get an overview of HMS Core Identity, Map and Account Kit, including its functions, open capabilities and business value.
HMS Core Map Service Introduction
HMS Core Map SDK is a set of APIs for map development in Android. The map data covers most countries outside China and supports multiple languages. The Map SDK uses the WGS 84 GPS coordinate system, which can meet most requirements of map development outside China. You can easily add map-related functions in your Android app, including:
Map display: Displays buildings, roads, water systems, and Points of Interest (POIs).
Map interaction: Controls the interaction gestures and buttons on the map.
Map drawing: Adds location markers, map layers, overlays, and various shapes.

Prerequisite
1.Huawei Phone EMUI 3.0 or later.
2.Non-Huawei phones Android 4.4 or later (API level 19 or higher).
3.Android Studio.
4.AppGallery Account.

App Gallery Integration process
1.Sign In and Create or Choose a project on AppGallery Connect portal.
2.Navigate to Project settings and download the configuration file.
3.Navigate to General Information, and then provide Data Storage location.

App Development
1.Create A New Project.
2.Configure Project Gradle.

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        google()
        jcenter()
        maven {url 'https://developer.huawei.com/repo/'}
    }
    dependencies {
        classpath "com.android.tools.build:gradle:4.0.1"
        classpath 'com.huawei.agconnect:agcp:1.4.2.300'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

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

task clean(type: Delete) {
    delete rootProject.buildDir
}

3.Configure App Gradle.

//  implementation 'com.huawei.hms:maps:4.0.0.301'
    implementation 'com.huawei.hms:maps:5.0.1.300'
    //site
    implementation 'com.huawei.hms:site:4.0.0.300'
    //location
    implementation 'com.huawei.hms:location:4.0.3.301'

    implementation 'com.squareup.retrofit2:retrofit:2.5.0'
    implementation 'com.squareup.retrofit2:converter-gson:2.5.0'
    implementation "com.squareup.retrofit2:adapter-rxjava2:2.6.2"

    implementation 'io.reactivex:rxjava:1.3.0'
    implementation 'io.reactivex:rxandroid:1.2.1'
    implementation 'com.android.support:multidex:1.0.3'


    implementation 'com.squareup.okhttp3:logging-interceptor:4.2.2'

    // RxAndroid
    implementation 'io.reactivex.rxjava2:rxjava:2.2.8'
    implementation 'io.reactivex.rxjava2:rxandroid:2.1.1'

4.Configure AndroidManifest.xml.

            android:name="install_channel"
            android:value="AppGallery" />
        <meta-data
            android:name="com.huawei.hms.client.appid"
            android:value="XXXXXXX" />`
5.Create Activity class with XML UI.

Tips and Tricks
Map data of Map Kit does not cover the Chinese mainland. Therefore, the Map SDK for Android, Map SDK (Java) for HarmonyOS, JavaScript API, Static Map API, and Directions API of Map Kit are unavailable in the Chinese mainland. For details about locations where the services are available.
The map zoom icons flash on the map on devices running Android 8 or earlier before the map is loaded. (This issue occurs at a low probability in Android 8, but does not occur in versions later than Android 8.)

Layout file (XML file): Set uiZoomControls to false.
Code file: Set the parameter of the HuaweiMapOptions.zoomControlsEnabled(boolean isZoomControlsEnabled) method to false.

## 
Conclusion
In this article, we have learned how to integrate HMS Core Identity and Map in Android application. After completely read this article user can easily implement Huawei User Address and Map APIs by HMS Core Identity, so that User can consult with doctor using Huawei User Address and redirect to Doctor location.
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.

Tips and Tricks
Identity Kit displays the HUAWEI ID registration or sign-in page first. The user can use the functions provided by Identity Kit only after signing in using a registered HUAWEI ID.
A maximum of 10 user addresses are allowed.
If HMS Core (APK) is installed on a mobile phone, check the version. If the version is earlier than 4.0.0, upgrade it to 4.0.0 or later. If the version is 4.0.0 or later, you can call the HMS Core Identity SDK to use the capabilities.

Conclusion
In this article, we have learned how to integrate HMS Core Identity in Android application. After completely read this article user can easily implement Huawei User Address APIs by HMS Core Identity, so that User can consult with doctor using Huawei User Address.

Intermediate: Know Your Doctor using Huawei Kits (Account, Crash and Analytics) in Android App.

ManojGunkar — Fri, 25 Feb 2022 09:11:43 +0000

Overview

In this article, I will create a DoctorConsultApp android application in which I will integrate HMS Core kits such as Huawei ID, Crash and Analytics.

Huawei ID Service Introduction

Huawei ID login provides you with simple, secure, and quick sign-in and authorization functions. Instead of entering accounts and passwords and waiting for authentication, users can just tap the Sign in with HUAWEI ID button to quickly and securely sign in to your app with their HUAWEI IDs.

Prerequisite
1.Huawei Phone EMUI 3.0 or later.
2.Non-Huawei phones Android 4.4 or later (API level 19 or higher).
3.HMS Core APK 4.0.0.300 or later
4.Android Studio
5.AppGallery Account.

App Gallery Integration process

1.Sign In and Create or Choose a project on AppGallery Connect portal.
2.Navigate to Project settings and download the configuration file.
3.Navigate to General Information, and then provide Data Storage location.

App Development

1.Create A New Project.
2.Configure Project Gradle.
3.Configure App Gradle.
implementation 'com.huawei.hms:identity:5.3.0.300' implementation 'com.huawei.agconnect:agconnect-auth:1.4.1.300' implementation 'com.huawei.hms:hwid:5.3.0.302'
4.Configure AndroidManifest.xml.
<uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
5.Create Activity class with XML UI.
MainActivity:
