      Description

      Hi guys, i'm trying to use Log4J2 in an Android (19) application and it's not working. Here is the code i have and the stacktrace i obtain when running the application.

      Am i missing something or is Log4J2 not working yet in an Android environment ?

      MyActivity.java
      import org.apache.logging.log4j.LogManager;
      import org.apache.logging.log4j.Logger;
      
      
      public class MyActivity extends Activity {
      
          static final Logger logger = LogManager.getLogger(MyActivity.class.getName());
      
          @Override
          protected void onCreate(Bundle savedInstanceState) {
              super.onCreate(savedInstanceState);
              setContentView(R.layout.activity_my);
              logger.error("TEST ############################################");
          }
