Is it possible to use `com.github.tony19:logback-android` with version 4?

And if not? How do I set logging level for packages?

IIUC it should be possible, but not with the android module (with the jvm module kotlin-logging-jvm)

And how should I do that in a multiplatform project with many common code? See also <https://kotlinlang.slack.com/archives/C3PQML5NU/p1688058646157229>

I don't know a way that's possible to do. In that case I would defer to the android log.
Do you know what is the advantage of `logback-android` over native android `Log`?

I could not find a working way, to configure android native Log. Since the upgrade I only get ERROR logs, but I need some packages with DEBUG log until they are stable enough. This can be easily configured via logback...

I can add support for that in android module itself (to pick between the two)

That would be really awesome. Currently I have the problem, that I upgraded kotlin-logging in a published library, but one of my project uses this library and Android has no logs anymore.

I can do something similar to here (that will require adding a system property): <https://github.com/oshai/kotlin-logging/blob/master/src/jvmMain/kotlin/io/github/oshai/kotlinlogging/internal/KLoggerFactory.kt>

do you think this is something that you can add to the app?

like `System.setProperty("kotlin-logging-to-logback-android", "true")`

That should be possible, but it should be `kotlin-logging-to-slf4j` . Personally I think it would be better to have slf4j as default, because it was the default in older kotlin-logging versions and is also the more usual one in the Android world.

can you open an issue in the repo please?

See also the table in the top of <https://source.android.com/docs/core/tests/debug/understanding-logging?hl=en>
`android.util.Log` is more for Android framework and system application

I am actually quite surprise because I didn't see popular frameworks with slf4j in the past in android

For example, timber is pretty popular and it uses Log: <https://github.com/JakeWharton/timber>

so what should be the default itself is something we should check more, but let's start with fixing the issue

I think I will start with the default as you suggested, but it might change in the future
