Android Question what sub is logcolor1?

[MbedAndroid]

from firebase i got some user crashes with always same errors:

vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv4=logcolor1
Fatal Exception: java.lang.NullPointerException

I dont have a logcolor1 in the program, the only logcolor which is used by UDG's app updater is called Logcolor. without the 1.
This crash happens 1 time during testing, only when the program is loaded. The app doesnt start, you will get a black screen.
Different devices, android 6-10.
For what/where is the logcolor1 used?

looking in the txt dump, it must be in the beginning after activitycreate.resume

ResumableSub_Activity_Create.resume(main.java:1197)

Built-in keywords are not obfuscated. It comes from your code or code added from one of the b4xlibs.

it is used in UDG's appupdater,but it isnt the cause i think.
