Due to the recent changes in Notification permissions in the Android 13 SDK, I need to update my app with FCM integration to obey the notifications rule. I have upgraded the compileSdk to 33 and also the targetSdk to 33. I have written code to ask POST_NOTIFICATIONS and the prompt appears. On pressing "Allow" the Notification Permission is enabled. But on sending a push notification the app receives no notification.
I only made changes in asking for the notification permission. Did not change anything in FirebaseMessagingService Class. The app was previously targetSdk 30.
class MyFirebaseMessagingService : FirebaseMessagingService() {
var intent: Intent? = null
var badgecount: Int = 0
override fun onMessageReceived(remoteMessage: RemoteMessage) {
if (remoteMessage.data.isNotEmpty()) {
try {
val json = JSONObject(remoteMessage.data.toString())
handleDataMessage(json)
} catch (e: Exception) {
Log.e("FIREBASEEXCEPTION:", e.message.toString())
}
}
if (remoteMessage.notification != null) {
sendNotification(remoteMessage.notification!!.body)
println("Message Notification Body:" + remoteMessage.notification!!.body)
}
super.onMessageReceived(remoteMessage)
}
private fun handleDataMessage(json: JSONObject) {
try {
val data = json.getJSONObject("body")
val badge = data.getString("badge")
val message = data.getString("message")
Log.e("FIREBASE_MSG:", message)
badgecount = badge.toInt()
sendNotification(message)
} catch (e: JSONException) {
Log.e("JSONEXCEPTION:", e.message.toString())
} catch (e: java.lang.Exception) {
}
}

ShortcutBadger.applyCount(this, badgecount)
