I don't exactly like this. The audit event records are very normalized. When
you have a specific kind of record, you can count on always having the certain
fields even if its value is (NULL). So, having fields swinging in and out by
configuration is not something I'd like to see start.

Can you show me an event that has the problem and what it looks like when its
fixed by this patch?

I'm 100% ok with the dynamic option changing it from NULL to a real value IMO a like

that better then what I currently have.

Issue:

comm field in task is only 16  chars, to small for most package names, and already contains the VM command. I really have no information of what Android App has created the issue.

Solution:

Get the proc cmdline info (not trust worthy, but can help debugging Android)

Now I know it was the NFC app
