I have a Java Project with a lot of files, which is using LOG4J. Now I am trying to Port it to the Android platform. Is it possible to reuse the code as it is, with LOG4J function calls?
Current understanding:
- Property configuration won’t work (beans dependency)
- I tried with LOG4J for Android and SL4J Lib. No success.
Working. But no use
org.apache.log4j.Logger root = org.apache.log4j.Logger.getRootLogger(); final SocketAppender appender = new SocketAppender("192.168.123.123", 3333); root.addAppender(appender); // SLF4J - Not working org.slf4j.Logger logger; logger = LoggerFactory.getLogger(MyClass.class); // LOG4J for Android - Not working ConfigureLog4J.configure(); logger = Logger.getLogger( MyClass.class );
Am I missing something? Pointer to any working examples?

Answer
Solved by using the android-logging-log4j.jar.
Here is sample code:
public class ALogger { public static org.apache.log4j.Logger getLogger(Class clazz) { final LogConfigurator logConfigurator = new LogConfigurator(); logConfigurator.setFileName(Environment.getExternalStorageDirectory().toString() + File.separator + "log/file.log"); logConfigurator.setRootLevel(Level.ALL); logConfigurator.setLevel("org.apache", Level.ALL); logConfigurator.setUseFileAppender(true); logConfigurator.setFilePattern("%d %-5p [%c{2}]-[%L] %m%n"); logConfigurator.setMaxFileSize(1024 * 1024 * 5); logConfigurator.setImmediateFlush(true); logConfigurator.configure(); Logger log = Logger.getLogger(clazz); return log; } }
In your code, replace the below lines:
PropertyConfigurator.configure(MY_PROP_FILE); logger = Logger.getLogger( MyClaZZ.class );
With:
logger = ALogger.getLogger(MyClazz.class);
