Major Description
This small Android project compiles using mvn clean install.
It includes something like
import org.apache.logging.log4j.LogManager; import org.apache.logging.log4j.Logger; // ... logger.info("=== Initialized ===");
For configuring log4j2, I use a programmatically approch (see Log4jConfigure.java) to
prevent the log4j2.xml Android issue as described in LOG4J2-728.
But I didn't see my logging output on logcat.
Seems that I need something like a LogcatAppender but couldn't find hints how to do that.
I found this project but it has no commits over the last 2 years and so it seems that it not fits to log4j2.
Seeing this output in logcat:
ERROR StatusLogger Log4j2 could not find a logging implementation. Please add log4j-core to the classpath. Using SimpleLogger to log to the console...
A bit further investigation:
- logging with logger.fatal() and logger.error() gave me output to logcat, but both with Level = Warning and Tag = System.err
- all other logger.warn() ... logger.trace() were suppressed
When checking the system property java.class.path, it returns ".", but this seems a normal circumstance (as described on developer.android.com).
So falling back to the key questions: How to configure log4j2 properly to produce correct Android logcat output?
- want to have the loglevel placed correctly
- using the classname for the logcat tag seems a nice idea
Could anybory help?
