Introduction
In this article, we can learn how to integrate the Huawei Account Kit in Book Reading app. So, I will provide the series of articles on this Book Reading 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.
Requirements
Any operating system (MacOS, Linux and Windows).
Must have a Huawei phone with HMS 4.0.0.300 or later.
Must have a laptop or desktop with Android Studio, Jdk 1.8, SDK platform 26 and Gradle 4.6 and above installed.
Minimum API Level 24 is required.
Required EMUI 9.0.0 and later version devices.
How to integrate HMS Dependencies
- First register as Huawei developer and complete identity verification in Huawei developers website, refer to register a Huawei ID.
- Create a project in android studio, refer Creating an Android Studio Project.
- Generate a SHA-256 certificate fingerprint.
- 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.
- Create an App in AppGallery Connect.
- Download the agconnect-services.json file from App information, copy and paste in android **Project **under **app **directory, as follows.
- Enter SHA-256 certificate fingerprint and click **Save **button, as follows.
- Click Manage APIs tab and enable Account Kit.
- 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' - 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' implementation 'androidx.recyclerview:recyclerview:1.2.1' - Now Sync the gradle.
- Add the required permission to the AndroidManifest.xml file.
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
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.
`class MainActivity : AppCompatActivity() {
private var mAuthManager: AccountAuthService? = null
private var mAuthParam: AccountAuthParams? = null
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
sign_btn.setOnClickListener(mOnClickListener)
}
private fun signIn() {
mAuthParam = AccountAuthParamsHelper(AccountAuthParams.DEFAULT_AUTH_REQUEST_PARAM)
.setIdToken()
.setAccessToken()
.setProfile()
.createParams()
mAuthManager = AccountAuthManager.getService(this@MainActivity, mAuthParam)
startActivityForResult(mAuthManager?.signInIntent, 1002)
}
private val mOnClickListener: View.OnClickListener = object : View.OnClickListener {
override fun onClick(v: View?) {
when (v?.id) {
R.id.sign_btn -> signIn()
}
}
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (requestCode == 1002 ) {
val authAccountTask = AccountAuthManager.parseAuthResultFromIntent(data)
if (authAccountTask.isSuccessful) {
Toast.makeText(this, "SigIn success", Toast.LENGTH_LONG).show()
val intent = Intent(this@MainActivity, Home::class.java)
startActivity(intent)
} else {
Toast.makeText(this, "SignIn failed: " + (authAccountTask.exception as ApiException).statusCode, Toast.LENGTH_LONG).show()
}
}
}
}`
In the Home.kt we can find the business logic.
`class Home : AppCompatActivity() {
lateinit var recyclerView: RecyclerView
var mBookAdapter: BookAdapter? = null
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_home)
recyclerView = findViewById(R.id.recycler_view)
mBookAdapter = BookAdapter()
recyclerView.adapter = mBookAdapter
}
}`
Create BookAdapter.kt class for holding the list.
`class BookAdapter(): RecyclerView.Adapter() {
private var titles = arrayOf("Life", "Young Adult", "Comedy", "Women", "Tragedy", "Science Fiction",
"Horror Stories", "Drama", "Society", "Biography")
private var images = intArrayOf(R.drawable.life, R.drawable.youth, R.drawable.comedy, R.drawable.women,
R.drawable.tragedy, R.drawable.science, R.drawable.horror, R.drawable.drama,
R.drawable.society, R.drawable.biography)
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): BookAdapter.ViewHolder {
val view = LayoutInflater.from(parent.context)
.inflate(R.layout.list_item, parent, false)
return BookAdapter.ViewHolder(view)
}
override fun onBindViewHolder(holder: BookAdapter.ViewHolder, position: Int) {
holder.itemTitle.text = titles[position]
holder.itemImage.setImageResource(images[position])
}
override fun getItemCount(): Int {
return titles.size
}
class ViewHolder(ItemView: View) : RecyclerView.ViewHolder(ItemView) {
var itemTitle: TextView = itemView.findViewById(R.id.titles)
var itemImage: ImageView = itemView.findViewById(R.id.images)
}
}`
In the activity_main.xml we can create the UI screen.
`<?xml version="1.0" encoding="utf-8"?>
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"
android:background="@drawable/book_fly"
tools:context=".MainActivity">
<TextView
android:id="@+id/act_main_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="left"
android:layout_marginLeft="20dp"
android:layout_marginTop="30dp"
android:text="Huawei E-Book Store"
android:textSize="32sp"
android:textColor="@color/hwid_auth_button_color_red"
android:textStyle="bold" />
<ImageButton
android:id="@+id/sign_btn"
android:layout_width="290dp"
android:layout_height="60dp"
android:layout_alignParentBottom="true"
android:layout_centerInParent="true"
android:layout_margin="15dp"
android:paddingTop="10dp"
app:srcCompat="@drawable/huawei_id_buttons" />
`
In the activity_home.xml we can create the UI screen.
`<?xml version="1.0" encoding="utf-8"?>
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:gravity="center_vertical"
android:orientation="vertical"
android:paddingLeft="8dp"
android:paddingRight="8dp"
tools:context=".Home">
<androidx.recyclerview.widget.RecyclerView
android:id="@+id/recycler_view"
android:layout_width="match_parent"
app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager"
android:layout_height="match_parent" />
`
In the list_item.xml we can create the list of items.
`<?xml version="1.0" encoding="utf-8"?>
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/list_view"
android:layout_marginLeft="-3dp"
android:layout_marginRight="0dp"
android:layout_marginBottom="5dp"
app:cardBackgroundColor="@color/hwid_auth_button_color_border"
app:cardCornerRadius="8dp"
app:cardElevation="3dp"
app:contentPadding="5dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:padding="5dp">
<TextView
android:id="@+id/titles"
android:layout_width="160dp"
android:layout_height="50dp"
android:layout_marginStart="10dp"
android:layout_marginLeft="15dp"
android:text="Item"
android:textSize="20sp"
android:textAlignment="viewStart"
android:textColor="@color/black"
android:textStyle="bold" />
<ImageView
android:id="@+id/images"
android:layout_width="150dp"
android:layout_height="60dp"
android:layout_gravity="right"
android:layout_marginLeft="55dp" />
</LinearLayout>

Tips and Tricks
Make sure you are already registered as Huawei developer.
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.
