I found a bug in the implementation while writing unit tests for a Timber binding, found in https://mvnrepository.com/artifact/org.slf4j/slf4j-android/1.7.25 (which also seems to be propagated into many forks of this impl). The bug is: AndroidLoggerAdapter:253 /** * Log an exception (throwable) at level DEBUG with an accompanying message. * * @param msg * the message accompanying the exception * @param t * the exception (throwable) to log */ public void debug(String msg, Throwable t) { log(Log.VERBOSE, msg, t); } -> debug log, logs with VERBOSE priority. I am more than happy to provide a PR, but I can't seem to find the location of the "official" Android implementation. could somebody please tell me where to find it? lg pf
