Description

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.

LoggerContext ctx = LoggerContext.getContext()
        Configuration config = ctx.getConfiguration();
        LoggerConfig loggerConfig = config.getLoggerConfig(LogManager.ROOT_LOGGER_NAME);
        loggerConfig.setLevel(myLogLevel);
        ctx.updateLoggers();

While getting the logger context, I am getting a ClassCastException.

05-26 22:33:21.011 E/AndroidRuntime( 9642): Caused by: java.lang.ClassCastException: org.apache.logging.log4j.simple.SimpleLoggerContext cannot be cast to org.apache.logging.log4j.core.LoggerContext
05-26 22:33:21.011 E/AndroidRuntime( 9642): at org.apache.logging.log4j.core.LoggerContext.getContext(LoggerContext.java:190)
05-26 22:33:21.011 E/AndroidRuntime( 9642): at org.apache.logging.log4j.core.config.Configurator.setRootLevel(Configurator.java:323)

Please help here.
