Above you mention you use xml configuration but I don't see one in that app.
Can you provide that? Log4j-API-android is providing an implementation that we
believe makes sense on android but without knowing what your logging
configuration does we cannot know for sure.
Log4J-core does not Have any Java 9 classes.
Log4J 2.3 was the last release to support java 6. Is there something in
log4j-core that uses Java 7 that android does not allow? Probably a lot
actually.

> Hi,
> I integrated the log4j with my Android application and did the initial
> config. It works fine. I have a menu item in "Settings" screen where I can
> change the log levels in my application. So, After I change the
> configuration, I need to update the loggers. So I am using following logic.
> {code:java}
> LoggerContext ctx = LoggerContext.getContext()
> Configuration config = ctx.getConfiguration();
> LoggerConfig loggerConfig =
> config.getLoggerConfig(LogManager.ROOT_LOGGER_NAME);
> loggerConfig.setLevel(myLogLevel);
> ctx.updateLoggers();
> {code}
> While getting the logger context, I am getting a ClassCastException.
