Let us move to development
I have created a project on Android studio with empty activity let's start coding.
In the MainActivity.kt we can create the business logic.
Code:
class MainActivity : AppCompatActivity() {
private val GET_ADDRESS = 1000
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
query_user_address.setOnClickListener {
if(isNetworkAvailable([email protected])){
getUserAddress()
}
else {
Toast.makeText(this, "Please check your internet connection...", Toast.LENGTH_SHORT).show()
}
}
}
// To parse user address selection, returning the selected user address and displaying the selected user address in text view.
@SuppressLint("SetTextI18n")
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
Toast.makeText(this, "onActivityResult requestCode $requestCode resultCode $resultCode", Toast.LENGTH_SHORT).show()
when (requestCode) {
GET_ADDRESS -> when(resultCode) {
RESULT_OK -> {
val userAddress = UserAddress.parseIntent(data)
if(userAddress != null){
val sb = StringBuilder()
sb.apply {
append("name: ${userAddress.name} ,")
append("city: ${userAddress.administrativeArea} ,")
append("area: ${userAddress.locality} ,")
append("address: ${userAddress.addressLine1} ${userAddress.addressLine2} ,")
append("phone: ${userAddress.phoneNumber} ,")
}
Toast.makeText(this, "user address is $sb", Toast.LENGTH_SHORT).show()
user_address.text = sb.toString()
}else {
user_address.text = "Failed to get user address."
}
}
RESULT_CANCELED -> {
}
else -> Toast.makeText(this, "Result is wrong, result code is $resultCode", Toast.LENGTH_SHORT).show()
}
else -> {
}
}
}
// To query the user addresses and open the user address selection page.
private fun getUserAddress() {
val req = UserAddressRequest()
val task = com.huawei.hms.identity.Address.getAddressClient(this).getUserAddress(req)
task.addOnSuccessListener { result ->
Toast.makeText(this, "onSuccess result code: ${result.returnCode}", Toast.LENGTH_SHORT).show()
try{
startActivityForResult(result)
}
catch (e: IntentSender.SendIntentException){
e.printStackTrace()
}
}.addOnFailureListener { e ->
Toast.makeText(this, "on Failed result code: ${e.message}", Toast.LENGTH_SHORT).show()
}
}
private fun startActivityForResult(result: GetUserAddressResult){
val status = result.status
if(result.returnCode == 0 && status.hasResolution()){
Toast.makeText(this, "The result had resolution", Toast.LENGTH_SHORT).show()
status.startResolutionForResult(this, GET_ADDRESS)
}
else {
Toast.makeText(this, "the response is wrong, the return code is ${result.returnCode}", Toast.LENGTH_SHORT).show()
}
}
fun isNetworkAvailable(context: Context?): Boolean {
if(context != null){
val connectivityManager = context.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
val aNetworkInfo = connectivityManager.activeNetworkInfo
aNetworkInfo?.let{
return aNetworkInfo.isAvailable
}
}
return false
}
}
In the activity_main.xml we can create the UI screen.

Beginner: Integration of Landmark recognition by Huawei ML Kit in apps (Kotlin)

Introduction
In this article, we can learn the integration of landmark recognition feature in apps using Huawei Machine Learning (ML) Kit. The landmark recognition can be used in tourism scenarios. For example, if you have visited any place in the world and not knowing about that monument or natural landmarks? In this case, ML Kit helps you to take image from camera or upload from gallery, then the landmark recognizer analyses the capture and shows the exact landmark of that picture with results such as landmark name, longitude and latitude, and confidence of the input image. A higher confidence indicates that the landmark in input image is more likely to be recognized. Currently, more than 17,000 global landmarks can be recognized. In landmark recognition, the device calls the on-cloud API for detection and the detection algorithm model runs on the cloud. During commissioning and usage, make sure the device has Internet access.

Introduction
In this article, we can learn how to integrate the Huawei Analytics Kit and Ads 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.
Analytics Kit
HUAWEI Analytics Kit provides analysis models to understand user behaviour and gain in-depth insights into users, products and content. It helps you to gain insight about user behaviour on different platforms based on the user behaviour events and user attributes reported by through apps.
AppGallery Connect
Find the Analytics using AppGallery connect dashboard.
Choose My Projects > Huawei Analytics > Overview > Project overview.
Project overview displays the core indicators of current project, such as the number of new users, User activity, User acquisition, User revisit, New user retention, Active user retention, User characteristics and Popular pages etc. providing a quick overview of the users and how they are using your app.
Ads Kit
Huawei Ads provides to developers a wide-ranging capabilities to deliver good quality ads content to users. This is the best way to reach target audience easily and can measure user productivity. It is very useful when we publish a free app and want to earn some money from it.
HMS Ads Kit has 7 types of Ads kits. Now we can implement Interstitial Ads in this application.
Interstitial ads are full-screen ads that cover the interface of an app. Such an ad is displayed when a user starts, pauses or exits an app, without disrupting the user's experience.
Requirements
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.

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 Analytics.
Java:
class MainActivity : AppCompatActivity() {
// Initialize the Analytics
var mInstance: HiAnalyticsInstance? = null
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
sign_btn.setOnClickListener(mOnClickListener)
// Initialize the Analytics function
initAna()
}
private fun initAna() {
// Enable Analytics Kit Log
HiAnalyticsTools.enableLog()
// Generate the Analytics Instance
mInstance = HiAnalytics.getInstance(this)
// Enable collection capability
mInstance?.setAnalyticsEnabled(true)
}
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) {
// Analytics data to send custom events
val bundle = Bundle()
bundle.putString("email", data!!.extras!!.getString("email" ))
bundle.putString("name", data.extras!!.getString("name"))
bundle.putString("phone", data!!.extras!!.getInt("phone").toString())
bundle.putString("marks", data!!.extras!!.getFloat("86.5").toString())
mInstance!!.onEvent(HAEventType.SIGNIN, bundle)
Toast.makeText(this, "SigIn success", Toast.LENGTH_LONG).show()
} else {
Toast.makeText(this, "SignIn failed: " + (authAccountTask.exception as ApiException).statusCode, Toast.LENGTH_LONG).show()
}
}
}
}
In the ListActivity.kt we can find the business logic for Ads.
Java:
class ListActivity : AppCompatActivity() {
// Initialize the Interstitial Ads Kit
private var interstitialAd: InterstitialAd? = null
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_list)
title = getString(R.string.interstitial_ad)
btn_alltypes.setOnClickListener {
loadInterstitialAd()
}
showInterstitialAd()
val actionBar = supportActionBar
actionBar!!.setDisplayHomeAsUpEnabled(true)
}
private val adListener: AdListener = object : AdListener() {
override fun onAdLoaded() {
super.onAdLoaded()
showToast("Ad loaded")
// Display an interstitial ad.
showInterstitialAd()
val intent = Intent([email protected], Home::class.java)
startActivity(intent)
}
override fun onAdFailed(errorCode: Int) {
showToast("Ad load failed with error code: $errorCode")
Log.d(TAG, "Ad load failed with error code: $errorCode")
val intent = Intent([email protected], Home::class.java)
startActivity(intent)
}
override fun onAdClosed() {
super.onAdClosed()
showToast("Ad closed")
Log.d(TAG, "onAdClosed")
val intent = Intent([email protected], Home::class.java)
startActivity(intent)
}
override fun onAdClicked() {
Log.d(TAG, "onAdClicked")
super.onAdClicked()
}
override fun onAdOpened() {
Log.d(TAG, "onAdOpened")
super.onAdOpened()
}
override fun onAdLeave() {
Log.d(TAG, "onAdLeaves")
super.onAdLeave()
}
}
private fun loadInterstitialAd() {
// Load an interstitial ad.
interstitialAd = InterstitialAd(this)
val adParam = AdParam.Builder().build()
interstitialAd!!.adId = getString(R.string.video_ad_id)
interstitialAd!!.loadAd(adParam)
interstitialAd!!.adListener = adListener
}
private val adId: String
get() = if (btn_alltypes.isClickable) {
getString(R.string.image_ad_id)
} else {
getString(R.string.video_ad_id)
}
private fun showInterstitialAd() {
// Display the ad
if (interstitialAd != null && interstitialAd!!.isLoaded) {
interstitialAd!!.show(this)
} else {
Toast.makeText(this, "Ad did not load", Toast.LENGTH_LONG).show()
}
}
private fun showToast(text: String) {
runOnUiThread {
Toast.makeText([email protected], text, Toast.LENGTH_LONG).show()
}
}
companion object {
private val TAG = ListActivity::class.java.simpleName
}
override fun onSupportNavigateUp(): Boolean {
