Introduction

In this article, we can find the Huawei Account Kit of Log in via SMS and Forgot password? features in Attendance Tracker app. The Log in via SMS is an alternative way of login with Huawei ID, instead of providing password user can enter SMS code from registered Phone Number. Forgot password? can be used when you forgot your password, you can reset the password using the Huawei ID and SMS code will be sent for verification. So, I will provide the series of articles on this Attendance Tracker App, in upcoming articles I will integrate other Huawei Kits.

Account Kit

Huawei Account Kit provides for developers with simple, secure, and quick sign-in and authorization functions. User is not required to enter accounts, passwords and waiting for authorization. User can click on Sign In with HUAWEI ID button to quickly and securely sign in to the app.

1. Any operating system (MacOS, Linux and Windows).

2. Must have a Huawei phone with HMS 4.0.0.300 or later.

3. Must have a laptop or desktop with Android Studio, Jdk 1.8, SDK platform 26 and Gradle 4.6 and above installed.

4. Minimum API Level 24 is required.

5. Required EMUI 9.0.0 and later version devices.

How to integrate HMS Dependencies

1. First register as Huawei developer and complete identity verification in Huawei developers website, refer to register a Huawei ID.

2. Create a project in android studio, refer Creating an Android Studio Project.

3. Generate a SHA-256 certificate fingerprint.

4. To generate SHA-256 certificate fingerprint. On right-upper corner of android project click Gradle, choose Project Name > Tasks > android, and then click signingReport, as follows.

Note: Project Name depends on the user created name.

5. Create an App in AppGallery Connect.

6. Download the agconnect-services.json file from App information, copy and paste in android Project under app directory, as follows.

7. Enter SHA-256 certificate fingerprint and click Save button, as follows.

Note: Above steps from Step 1 to 7 is common for all Huawei Kits.

8. Click Manage APIs tab and enable Account Kit.

9. Add the below maven URL in build.gradle(Project) file under the repositories of buildscript, dependencies and allprojects, refer Add Configuration.

maven { url 'http://developer.huawei.com/repo/' }
classpath 'com.huawei.agconnect:agcp:1.6.0.300'

10. Add the below plugin and dependencies in build.gradle(Module) file.

apply plugin: id 'com.huawei.agconnect'
// Huawei AGC
implementation 'com.huawei.agconnect:agconnect-core:1.6.0.300'
// Huawei Account Kit
implementation 'com.huawei.hms:hwid:6.3.0.301'
// Huawei Ads Kit
implementation 'com.huawei.hms:ads:3.4.51.300'

11. Now Sync the gradle.

12. Add the required permission to the AndroidManifest.xml file.

// Account Kit
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
// Ads Kit
<uses-permission android:name="android.permission.INTERNET" />

Let us move to development

I have created a project on Android studio with empty activity let us start coding.

In the MainActivity.kt we can find the business logic for ads.

class MainActivity : AppCompatActivity() {

override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)

// Initialize the Huawei Ads SDK
HwAds.init(this)
loadDefaultBannerAd()
}

// To get Banner view from the activity_main.xml. It will display at bottom of the page.
private fun loadDefaultBannerAd() {
val bottomBannerView = findViewById<BannerView>(R.id.hw_banner_view)
val adParam = AdParam.Builder().build()
bottomBannerView.adId = getString(R.string.banner_ad_id) // banner_ad_id is testw6vs28auh3
bottomBannerView.bannerAdSize = BannerAdSize.BANNER_SIZE_SMART
bottomBannerView.loadAd(adParam)
}

}

In the activity_main.xml we can create the UI screen.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity">

<com.huawei.hms.ads.banner.BannerView
android:id="@+id/hw_banner_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_marginTop="10dp"
android:layout_marginBottom="10dp"/>

</LinearLayout>

In the Home.kt we can find the business logic for logout.

class Home : AppCompatActivity() {

private var mAuthManager: AccountAuthService? = null
private var mAuthParam: AccountAuthParams? = null

override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_home)

img_logout.setOnClickListener(mOnClickListener)

}

private fun signOut() {
mAuthParam = AccountAuthParamsHelper(AccountAuthParams.DEFAULT_AUTH_REQUEST_PARAM)
.createParams()
mAuthManager = AccountAuthManager.getService(this@Home, mAuthParam)
val signOutTask = mAuthManager?.signOut()
signOutTask?.addOnSuccessListener {
Toast.makeText(this, "signOut Success", Toast.LENGTH_SHORT).show()
val intent = Intent(this@Home, MainActivity::class.java)
startActivity(intent)
}?.addOnFailureListener {
Toast.makeText(this, "signOut fail", Toast.LENGTH_SHORT).show()
}
}

private val mOnClickListener: View.OnClickListener = object : View.OnClickListener {
override fun onClick(v: View?) {
when (v?.id) {
R.id.img_logout -> signOut()
}
}
}

}

In the activity_home.xml we can create the UI screen.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".Home">

<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="center"
android:padding="10dp"
android:layout_marginTop="20dp">
<ImageView
android:id="@+id/img_logout"
android:layout_width="150dp"
android:layout_height="60dp"
android:layout_marginRight="20dp"
android:layout_marginTop="20dp"
android:src="@drawable/logout"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="@color/black"
android:layout_marginRight="20dp"
android:layout_marginTop="10dp"
android:textSize="18sp"
android:text="Logout"/>
</LinearLayout>

</LinearLayout>

Tips and Tricks

1. Make sure you are already registered as Huawei developer.

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

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

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

5. Make sure all the dependencies are added properly.
