Are breakpoints inside inline lambdas supposed to work normally? I want to know if I'm doing something wrong, or if that's just the way things are.

I think it will be affected by whether lambda expressions are inlined or not

I'm getting really weird behavior (debugger stopping and showing the line being an

import

line, but mostly just not stopping at all) when it comes to inline functions.

If the function defined with the inline keyword receives a lambda expression, the content of the lambda expression is also inlined. the breakpoint issue with inline lambda has been mentioned in the book "kotlin in action".

Ok, so it's a known problem

Breakpoints in lambda functions seems to be troublesome across many languages. It's an issue I've had in Swift and Java.

It works perfectly fine in non-inline lambdas though

Most annoying was when I had a breakpoint in Java, trying to fix a NPE - but the breakpoint would only fire after the lambda completed no matter where it was placed. Never figured out why...

Sure, but there should be some source-map-like information, at least in the debug build, that maps it back to the original code

Makes me curious to see the machine code but man, Android debug Kotlin machine code is super hard to read.
