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
Add the following to your dependencies ( add jcenter to your repositories if you haven’t)
And that’s basically it. SLF4J will automatically look for implementations of
ILoggerFactory in the classpath (so don’t add this parallel to
Log level mapping
The priorities will be converted to LogCat’s priority level and passed to
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.
Logger 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.
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.
