public class Log4jUtil {

private static Logger gLogger;

public static void configLog(String msg) {
final LogConfigurator logConfigurator = new LogConfigurator();

logConfigurator.setFileName(Environment.getExternalStorageDirectory()
+ File.separator + "crifanli_log4j.log");
// Set the root log level
logConfigurator.setRootLevel(Level.INFO);
// Set log level of a specific logger
logConfigurator.setLevel("org.apache", Level.INFO);
logConfigurator.configure();

// gLogger = Logger.getLogger(this.getClass());
gLogger = Logger.getLogger("CrifanLiLog4jTest");
