A certain model of device cannot parse the payload of the data message.

• Android Studio version: 4.1.3
• Firebase Component: Cloud Messaging
• Component version: 21.1.0

Most models can work normally, but a user’s device crashed because it could not parse the payload of the data message.

This is the code.

class MyFirebaseMessagingService : FirebaseMessagingService() {
    override fun onMessageReceived(remoteMessage: RemoteMessage) {
        if (remoteMessage.data.isNotEmpty()) {
            val notificationType = remoteMessage.data.getValue("notification_type").toInt()
        }
    }
}

This is the payload when I pass the parameters to https://fcm.googleapis.com/fcm/send.

{
   "data":{
      "notification_type":1
   },
   "to":"xxxxxxxxxxx"
}

I get the report from Crashlytics.

@chliangGoogle I found that I did not receive the same crash from the same device in the past two days. Thank you.

Here is the payload when I pass the parameters to https://fcm.googleapis.com/fcm/send.

{"data":{"notification_type":1,"subscription_id":"627","subscription_title":"侯友宜","ref":"ae56de687328d21cc42b168a637c66ff","is_collected":false,"title":"[討論] 真的覺得陳其邁對防疫觀念很有s...","summary":"乃至於現在嚴格稽查『傳統市場』\n\n都很認真\n\n然後在施打疫苗方面\n\n陳其邁在『三...","content":"現在這樣看下來\n\n各地方首長之間互相比較一下\n\n陳其邁真的算...","src":"PTT","ch":"政黑板","author":"chungrew","url":"https://www.ptt.cc/bbs/HatePolitics/M.1622515747.A.044.html","senti":"負面","pt":"主文","stype":"BBS","cc":0,"lc":0,"dc":0,"sc":0,"time":"2021-06-01 10:49","is_sound_opened":true},"to":"xxxxxxxxxx"}

Here is the code in onMessageReceived.

class MyFirebaseMessagingService : FirebaseMessagingService() {
    override fun onMessageReceived(remoteMessage: RemoteMessage) {
        if (remoteMessage.data.isNotEmpty()) {
            val notificationType = remoteMessage.data.getValue("notification_type").toInt()

            when (notificationType) {
                0 -> {
                    val isSoundOpened = remoteMessage.data.getValue("is_sound_opened").toBoolean()
                }
                1 -> {
                    val isSoundOpened = remoteMessage.data.getValue("is_sound_opened").toBoolean()
                }
                2 -> {
                    val isSoundOpened = remoteMessage.data.getValue("is_sound_opened").toBoolean()
                }
                3 -> {
                    val isSoundOpened = remoteMessage.data.getValue("is_sound_opened").toBoolean()
                }
            }
        }
    }
}

Here is the report from Firebase Crashlytics.

This report is currently only received on Samsung Galaxy J6 (Android 8.0), and no problem with the emulator used in Android Studio.

Unfortunately, I do not own this type of device, and it comes from a customer.

I tried to find an image file and install it to the emulator to reproduce this problem, but Samsung’s official website does not provide an image file of this model.

For business purposes, I receive an average of 130 crash reports a day.
