Notification click onNewIntent not called

This is how activity declared in Manifest

<activity
    android:name=".view.activity.HomeActivity"
    android:exported="true"
    android:launchMode="singleTop"
    android:label="@string/app_name"
    android:theme="@style/AppTheme.Toolbar">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />

        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

And this is how I generate the notification

val notificationManager = applicationContext.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
    val channel = NotificationChannel("1", "MyApp", NotificationManager.IMPORTANCE_DEFAULT)
    notificationManager.createNotificationChannel(channel)
}

val notificationLayout = RemoteViews(applicationContext.packageName, R.layout.notification_view)
val notificationLayoutExpanded = RemoteViews(applicationContext.packageName, R.layout.notification_big_view)
updateLayout(notificationLayout, notificationLayoutExpanded, data)

val intent = Intent(applicationContext, HomeActivity::class.java).apply {
    flags = Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_SINGLE_TOP
    putExtra("Id", Id)
}
val pendingIntent: PendingIntent = PendingIntent.getActivity(applicationContext, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT)

val notification = NotificationCompat.Builder(applicationContext, "1")
        .setContentTitle("MyApp")
        .setSmallIcon(R.drawable.circle)
        .setCustomContentView(notificationLayout)
        .setCustomBigContentView(notificationLayoutExpanded)
        .setStyle(NotificationCompat.DecoratedCustomViewStyle())
        .setContentIntent(pendingIntent)
        .setAutoCancel(true)

notificationManager.notify(1, notification.build())

But when I tap on the notification onNewIntent called sometimes only (Maybe if app in open state, I can't guess correctly).

onNewIntent is only called if the activity is already open, It won't be called if the Activity is not open.

This means that if your activity was closed, it will start normally and onCreate will be called. You can pass a flag in your intent that tells your Activity that it was started from notification, then you find that flag in your onCreate and if it exists, you call the same functions as you did in onNewIntent():

val intent = Intent(applicationContext, HomeActivity::class.java).apply {
    flags = Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_SINGLE_TOP
    putExtra("Id", Id)
    putExtra("notificationIntent", true);
}

And in your OnCreate():

boolean isNotificationIntent = getIntent().getExtras().getBoolean("notificationIntent", false);

if(isNotificationIntent){
   DoSameWorkAsOnNewIntent();
}
