linkslf4j-timber

The motivation of this project was to ease using existing libraries which use SLF4J as their logging framework on the Google Android platform in combination with Jake Wharton's Timber logging utility.

This project is based on the official slf4j-android implementation (+ bugfixes) but directs the logging calls mainly to Timber.log(...);.

linkQuickstart

Add the following to your dependencies (add jcenter to your repositories if you haven't)

1compile 'at.favre.lib:slf4j-timber:1.0.0'

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)

linkDownload

The artifacts are deployed to jcenter and Maven Central.

linkDescription

linkLog level mapping

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.

linkLogger name mapping

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.

linkLimitations

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.

linkBuild

Assemble the lib with the following command

1./gradlew :slf4j-timber:assemble

The .aar files can then be found in /slf4j-timber/build/outputs/aar folder
