This is a library that allows pure Java / Kotlin modules or libraries using SLF4J as their logging framework to bridge on the Google Android platform in combination with Jake Wharton's Timber logging utility.
It's based on the patrickfav/slf4j-timber project with a modern take using Kotlin and the latest version of SLF4J (currently v2.0.6).
Attention: since v0.0.3 the artifact is migrated from JitPack to Maven Central.
Add the slf4j-timber artifact from this repository as a dependency in your app module:
dependencies {
implementation("com.jakewharton.timber:timber:5.0.1")
implementation("io.github.unveloper:slf4j-timber:0.0.8")
}In the pure Java / Kotlin modules should be present the SLF4J artifact:
dependencies {
implementation("org.slf4j:slf4j-api:2.0.6")
}And that's basically it. SLF4J will automatically look for implementations of ILoggerFactory in the classpath (so don't add this
parallel to org.slf4j:slf4j-android)
Check out the source code to see an example app.
From v0.0.1 to v0.0.3
Follow the guidelines from jitpack.io to add the JitPack repository to your build file if you have not.
Typically, this means an edit to your settings.gradle.kts file to add a new repository definition in the repositories block, like this:
dependencyResolutionManagement {
repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
repositories {
google()
mavenCentral()
maven("https://jitpack.io")
}
}
Then add the old slf4j-timber artifact (com.github.unveloper:slf4j-timber) from this repository as a dependency in your app module:
dependencies {
implementation("com.jakewharton.timber:timber:5.0.1")
implementation("com.github.unveloper:slf4j-timber:0.0.3")
}| slf4j-timber | Timber | SLF4J |
|---|---|---|
| 0.0.8 | 5.0.1 | 2.0.6 |
| 0.0.7 | 5.0.1 | 2.0.5 |
| 0.0.6 | 5.0.1 | 2.0.4 |
| 0.0.5 | 5.0.1 | 2.0.3 |
| 0.0.4 | 5.0.1 | 2.0.2 |
| 0.0.3 | 5.0.1 | 2.0.1 |
| 0.0.2 | 5.0.1 | 2.0.0 |
| 0.0.1 | 5.0.1 | 2.0.0 |
The priorities will be converted to LogCat's priority level and passed to
Timber.log(...);. The Log.isLoggable() are not respected here, since Timber
should be responsible to decide when to log what. The following table shows
the mapping from SLF4J log levels to LogCat log levels.
| SLF4J | Android/Timber |
|---|---|
| TRACE | VERBOSE |
| DEBUG | DEBUG |
| INFO | INFO |
| WARN | WARN |
| ERROR | ERROR |
Logger instances created using the LoggerFactory are named either according to the name given as parameter, or the fully qualified class name of the class given as parameter. No truncating will take place since Timber handles this itself.
The Android-Timber binding implementation currently does not support Markers. All logging methods which have a Marker parameter simply delegate to the corresponding method without a Marker parameter, i.e., the Marker parameter is silently ignored.
