I’ve installed logging feature, but it seems not working

install(Logging) {
    logger = Logger.ANDROID
    level = LogLevel.ALL
}

implementation "io.ktor:ktor-client-logging-jvm:$ktorVersion"

in logs I only see exception:

2020-03-05 16:16:33.829 1383-1383/? W/System.err: SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".

2020-03-05 16:16:33.829 1383-1383/? W/System.err: SLF4J: Defaulting to no-operation (NOP) logger implementation

2020-03-05 16:16:33.829 1383-1383/? W/System.err: SLF4J: See <http://www.slf4j.org/codes.html#StaticLoggerBinder> for further details.

is there a way to make it work ?

Logger.ANDROID is actually based on the default Ktor JVM logger which uses SLF4J and needs you to add that dependency. Alternatively you can use

Logger.SIMPLE

which just uses

println()

or create your own like

logger = object : Logger {
    override fun log(message: String) {
        println(message) // or Log.d() or Timber.d() or whatever
    }
}

Thx, I’ll try to add slf4j dependency. I’ve followed documentation, but this info is missing

These info should be added to the ktor logging page
