Getting DeadSystemException on Samsung SMG950U (Android 8.0.0) and SM 955 (Android 8.0.0)

Question

I am working on a native android app & getting the following report in my Crashlytics but I am unable to figure the the exact reason for this.

I have two activities SplashActivity and MapActivity in my app. There are lot of things going on in the MapActivity which are a bit memory consuming.

• Getting location using LocationManager for getting nearby places from server.
• Fetching list of locations from server, parsing into a list (Retrofit)
• Generating bitmap containing dynamic text strings from list to be used for the markers (Using AsyncTask)
• Displaying the markers on the Google map.

Crash Report :

    java.lang.RuntimeException: android.os.DeadSystemException

    Caused by: android.os.DeadSystemException

Devices affected:

• Samsung SMG950U (Android 8.0.0)
• SM 955 (Android 8.0.0)

What I have read already:

• Android DeadSystemException

• DeadSystemException start service Android 7

Unfortunately, these links were not really helpful. I am sure the device wasn't restarting while it crashed. And, other apps work fine on the device. I do not own that device, I am just getting these in my Crashlytics.

If atleast I get to reproduce it on some device in the cloud for ex. using GenyMotion & get hands on the LogCat logs, it would be of great help.

Thanks!
