We are using image is our push notification. This is the code to get the bitmap from URL:
try {
return BitmapFactory.decodeStream(URL(url).content as InputStream)
} catch (e: Exception) {
//Used for debugging production data only
if (BuildConfig.FLAVOR.equals("production", true)
&& BuildConfig.BUILD_TYPE.equals("release", true)) {
if (logData != null)
FirebaseCrashlytics.getInstance().setCustomKey("Push Notification Test Payload", logData?.toString()
?: "")
FirebaseCrashlytics.getInstance().recordException(e)
}
}
Earlier it was being used directly but since it's a long running task so I moved it inside CoroutineScope to avoid NetworkOnMainThreadException as below:
CoroutineScope(Dispatchers.IO).launch {
val bitmap = getBitmap(imagePath!!)
val largeIcon = BitmapFactory.decodeResource(this@PushMessagingService.resources,
R.drawable.notification_big_icon)
withContext(Dispatchers.Main) {
if (bitmap != null) {
val notificationStyle = NotificationCompat.BigPictureStyle()
notificationStyle.bigPicture(bitmap)
notificationStyle.setSummaryText(msg)
buildNotification(channelId, msgTitle, msg, defaultSoundUri, contentIntent,
notificationStyle, largeIcon, notificationManager, notificationID)
} else {
val notificationStyle = NotificationCompat.BigTextStyle()
buildNotification(channelId, msgTitle, msg, defaultSoundUri, contentIntent,
notificationStyle, largeIcon, notificationManager, notificationID)
}
}
}
But now I am getting lots of UnknownHostException stack trace in Crashlytics. This is stack trace:

I got the server checked and its working fine. That raised me some concerns:
- Is anything wrong in my implementation with respect to push notifications? Since, I am not facing any issue anywhere in rest of app.
- What would be the efficient way to fetch bitmap from url in case of push notifications?
from Fetch image in FirebaseMessagingService causing UnknownHostException
