LogCat filtering - include and exclude at the same time

Question

I'd like to show logs that contain MainActivity but don't contain ActivityManager, so that this match is excluded:

I/ActivityManager: Start proc 2666:com.example.app/u0000 for activity {com.example.app/com.example.app.MainActivity}

I tried as suggested here:

(?=(MainActivity))(?!(ActivityManager))

But it didn't work.

You could make use of a single negative l lookaheadand, use an anchor ^ at the start of the string.

^(?!.*\bActivityManager\b).*\bMainActivity\b.*

That will match

^ Start of string
(?!.*\bActivityManager\b) Negative lookahead, assert that ActivityManager is not present
.*\bMainActivity\b.* Match the whole line with bMainActivity
