android - RemoteServiceException crashing my app on MIUI 11

Question

I started receiving a weird crashes from MIUI 11 devices running Android 11 (so far only Mi 10 and Mi 10 lite 5G). I think this is a platform issue and nothing in my app as it's super specific to Xiaomi Android 11.

Fatal Exception: android.app.RemoteServiceException
Bad notification(tag=null, id=3249) posted from package de.crysxd.octoapp, crashing app(uid=10334, pid=23788): Couldn't inflate contentViewsjava.lang.NullPointerException: Attempt to invoke virtual method 'android.app.Notification$MessagingStyle android.app.Notification$MessagingStyle.setConversationType(int)' on a null object reference

I know similar crashes can happen if you e.g. use SVG icons on old devices, but I already use PNG. There are only two types of notification the device shows, one is a foreground service and one comes from Firebase. From the timing of the crash, it seems unlikely to be the Firebase notification.

Here is the code I use to create to notification (here in full):

private fun createProgressNotification(progress: Int, title: String, status: String) = createNotificationBuilder()
        .setContentTitle(title)
        .setContentText(status)
        .setProgress(maxProgress, progress, false)
        .setOngoing(true)
        .addCloseAction()
        .setNotificationSilent()
        .build()

    private fun createCompletedNotification(name: String?) = createNotificationBuilder()
        .setContentTitle(getString(R.string.notification_print_done_title))
        .apply {
            name?.let {
                setContentText(it)
            }
        }
        .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
        .build()

    private fun createDisconnectedNotification() = createNotificationBuilder()
        .setContentTitle(getString(R.string.notification_printing_lost_connection_message))
        .setContentText(lastEta)
        .setProgress(maxProgress, 0, true)
        .addCloseAction()
        .setOngoing(false)
        .setNotificationSilent()
        .build()

    private fun createInitialNotification() = createNotificationBuilder()
        .setContentTitle(getString(R.string.notification_printing_title))
        .setProgress(maxProgress, 0, true)
        .setOngoing(true)
        .addCloseAction()
        .setNotificationSilent()
        .build()

    private fun createNotificationBuilder() = NotificationCompat.Builder(this, notificationChannelId)
        .setColorized(true)
        .setColor(ContextCompat.getColor(this, R.color.primary_light))
        .setSmallIcon(R.drawable.ic_notification_default)
        .setContentIntent(createStartAppPendingIntent())

Anyone having the same issue or knows a solution?

Answer 1

My previous answer is hidden. Update the system to MIUI 12.2.7 and then got the crash. I have a notification to update per second in my app and the crash only happens sometimes after the app keeps running for a while.
