I'm trying to integrate Log4j2 in Android but getting the following error message:
java.lang.ClassCastException: org.apache.logging.log4j.simple.SimpleLoggerContext cannot be cast to org.apache.logging.log4j.core.LoggerContext
import org.apache.logging.log4j.Level;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.core.Logger;
import org.apache.logging.log4j.core.LoggerContext;
import org.apache.logging.log4j.core.appender.SyslogAppender;
LoggerContext context = (LoggerContext) LogManager.getContext();
Logger root = context.getLogger("MainActivity");
SyslogAppender appender = obtainAppender();
if (!appender.isStarted())
appender.start();
root.addAppender(appender);
root.setAdditive(false);
root.setLevel(Level.DEBUG);
root.debug("This is a test message");
You need to have both the core and api jar in the classpath. (See the log4j2 FAQ page.)
