Bug? [CLOSED] Unused Subs false positive

[lemonisdead]

Hello,

For information

I had new "Sub not used" log entries on a known project. So, I took a smaller (lighter) one to test and saw the same behavior
This sample code is Stevel05's AudioRecord's demo project

• out of the box after having fixed things which changed over the years (like targetSdk) to have a clear log but without changing any part of its initial source when there is no underscore in the sub's name, I get the "unused sub" warning
• changing it clears the warning
• changing it back produces the warning

I am on release mode (without obfuscation). I have seen this even without using the threading initially.

This is not a bug.

The compiler cannot know that this sub is called from the Threading library. Once you add an underscore the compiler assumes that this is an event sub so the warning is removed.

You should add an underscore to also avoid obfuscation issues.
