I have problems with receiving the notifications (made by the wear application) on my samsung watch 4 wear os 3.5. My code was working until the recent update; which basically started a Foreground Service with a notification. The service is running, but the notification is not visible. I have no errors. Other than this, normal notifications are not showing neither, made BroadcastReceiver (alarms in every 15 min).
I made a dummy app, which has only one button and generates a notification (nothing special), but it does (or actually does not) the same thing: I can not see the notification.
Steps:
- create a notification channel
- toast a text
- create a notification
Code:
class MainActivity : Activity() {
private lateinit var binding: ActivityMainBinding
val CHANNEL_ID = "test1234"
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding = ActivityMainBinding.inflate(layoutInflater)
setContentView(binding.root)
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
// Create the NotificationChannel
val name = getString(R.string.channel_name)
val descriptionText = getString(R.string.channel_description)
val importance = NotificationManager.IMPORTANCE_HIGH
val mChannel = NotificationChannel(CHANNEL_ID, name, importance)
mChannel.description = descriptionText
// Register the channel with the system; you can't change the importance
// or other notification behaviors after this
val notificationManager = getSystemService(NOTIFICATION_SERVICE) as NotificationManager
notificationManager.createNotificationChannel(mChannel)
}
// get reference to button
val btn_click_me = findViewById<Button>(R.id.btn_click_me)
// set on-click listener
btn_click_me.setOnClickListener {
Toast.makeText(this@MainActivity, "You clicked me.", Toast.LENGTH_SHORT).show()
var builder = Notification.Builder(this, CHANNEL_ID)
.setSmallIcon(R.drawable.logo)
.setContentTitle("Test title")
.setContentText("Test content")
.setPriority(Notification.PRIORITY_DEFAULT)
val notificationManager = getSystemService(NOTIFICATION_SERVICE) as NotificationManager
notificationManager.notify(1, builder.build())
}
}
}
Can you see anything stupid in my code? The CHANNEL_ID is the same both when creating the channel and creating the builder. The Notification has an ID > 0 (as I saw, 0 as the ID is not working); I also tried with other IDs as well.
I saw there are a "huge" improvement in the notifications with the latest SW upgrade (which can not been undone ........), but it is not working for me at all.
Is there anyone who had the same problem or sees the problem in my dummy code?
Kind regards,
