Hi
Im new to Kotlin Logging and need some help 😄

[Tower Guidev2]

Im looking to replace com.jakewharton.timber:timber:5.0.1 in my Android applications with "something"
and currently looking at

api 'io.github.microutils:kotlin-logging:2.1.23'
api 'org.slf4j:slf4j-android:1.7.36'

i have a very basic logger working fine in my application however a number of questions arise from what i am seeing in my logcat output

1). i would like to have one "logger" defined as follows in my base activity and use this to log messages in all the activities that extend it

import android.os.Bundle
import androidx.activity.ComponentActivity
import dagger.hilt.android.AndroidEntryPoint
import mu.KotlinLogging

@AndroidEntryPoint
open class FoundationActivity : ComponentActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

    }

    companion object{
        val logger = KotlinLogging.logger {this@Companion}
    }
}

the above works fine, apart from the log messages contain the FoundationActivity name and not the extending activity

E/FoundationActivity: This is logging of - kotlin-logging error 2c5c1d75-2968-4cf0-a26f-64231a097ec6
W/FoundationActivity: This is logging of - kotlin-logging warn 474cf564-45eb-4f7b-97ab-e7a981fa675e
I/FoundationActivity: This is logging of - kotlin-logging INFO 88b8c2e0-706d-4170-bc4e-1ecab98f1606

do i have to have a logger defined in each seperate activity to achieve my desired output? or is there an approach that will
allow me to have a single logger that reports each "calling" activity

2). i understand debug logs will only show when isDebugEnabled is true, how do i enable debug?
what documentation have i missed?

1. for logger to write the desired name you'll need to define one per file/ class (and make it private). this is the best practice when defining loggers as this helps to find the message (you know in what file it was written).

about debug logs check how to enable them in android

under the hood this facade is calling the android native logging to do the logging - nothing more than that
