Overview

The generated getter function setRejCause expects a valid Integer object. The object should be coverted in to a primitive int, which does not happen, when the converted Integer value is null (and not a valid Integer): java.lang.NullPointerException: Attempt to invoke virtual method 'int java.lang.Integer.intValue()' on a null object reference

This is not a duplicate of https://github.com/CellularPrivacy/Android-IMSI-Catcher-Detector/issues/870, since it solves a different issue.

I have already made a fix for this and will make a pull request later. I created this issue just to trace this specific issue.

I see a crash too when trying to download the database. I did following: 1) clear all app data, 2) get ID-key, 3) start the DB download. At step 3 the app always crashes :(

Here is few lines from log-file, which I think are relevant
