Android - Weird Runtime Exception Found on Crashlytics

so today i was checking my Crashlytics and found Application is Been crashed 88 times but couldn't find the source
Here is the Exception Detail
java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String com.example.f.f.a()' on a null object reference

When you release an Apk file, you can define a path for mapping file which generate by pro-guard. Then you can use it to de-obfuscate com.example.f.f.a() and find location of error.

How to fix Developer Console testing failure, without reference to the own code?

The Google Play Developer Console shows me the following Pre-Launch-Report, for the Galaxy S6, after uploading the APK. The other nine devices, which Google uses to test the APK, have no error.
The provided stacktrace shows none of my code lines. How can I figure out, whether this is a real problem, and how can I fix it, if it is not based on my code?
Developer Console output:
Problem: java.lang.NullPointerException: Attempt to read from field 'java.lang.String android.accounts.Account.type' on a null object reference

Is this normal? Why do I get this error only for the Galaxy S6?

Meteor Cordova app: Android crash

My app started crashing on my Android device. It used to work well and I did not change anything... I think it is related to Cordova but I have no clue why it suddenly started to crash.
Here is the log:

Any idea?

I tried to look for this error online, but couldn't find anything. I assume it's related to some system app that has one of her permissions unapproved (I don't know which could be the one), or maybe related to my Xposed Framework installation.
What could it be?
Thank you for your help.

its not any other problem did you see Attempt to invoke virtual method 'void android.app.AppOpsManager.checkPackage(int, java.lang.String)' on a null object reference. you have calling some null object reference.

Getting crashes inside Instabug on Android app. This is from the store version of the app so I do not have steps to reproduce. Thank you!

This bug should be solved in later versions.
Can you try out v2.3.1 and tell me how it goes?

This issue has been solved since version 3.0.5.
You just need to upgrade to latest version >= v3.0.5
