android java is not enclosing class

Question

this is my class

 public class mm {
 public class MessageHandler {
 public HashMap<String, Command> commandMap;
 public MessageHandler() {
 this.commandMap = new HashMap<>();
 commandMap.put("init", new CreateOfferCommand());
 commandMap.put("offer", new CreateAnswerCommand());
 commandMap.put("answer", new SetRemoteSDPCommand());
 commandMap.put("candidate", new AddIceCandidateCommand());
 }
 public Emitter.Listener onMessage = new Emitter.Listener() {
 @Override
 public void call(Object... args) {
 JSONObject data = (JSONObject) args[0];
 try {
 String from = data.getString("from");
 String type = data.getString("type");
 JSONObject payload = null;
 if(!type.equals("init")) {
 payload = data.getJSONObject("payload");
 }
 // if peer is unknown, try to add him
 if(!peers.containsKey(from)) {
 // if MAX_PEER is reach, ignore the call
 int endPoint = findEndPoint();
 if(endPoint != MAX_PEER) {
 Peer peer = addPeer(from, endPoint);
 peer.pc.addStream(localMS);
 commandMap.get(type).execute(from, payload);
 }
 } else {
 commandMap.get(type).execute(from, payload);
 }
 } catch (JSONException e) {
 e.printStackTrace();
 }
 }
 };
 public Emitter.Listener onId = new Emitter.Listener() {
 @Override
 public void call(Object... args) {
 String id = (String) args[0];
 mListener.onCallReady(id);
 }
 };
 public Emitter.Listener onCall = new Emitter.Listener() {
 @Override
 public void call(Object... args) {
 String id = (String) args[0];
 mListener.onCalling(id);
 }
 };
}
 ......................

}

and when i call the inner class from another class its give me an enclosing class

 mm.MessageHandler messageHandler = new mm.MessageHandler();

when i make inner class messageHandler a static the error gone but its shown anothe error inside inner class so can i call the inner class without make it static ?

Answer 1

mm n = new mm(); 
mm.MessageHandler messageHandler = n.new MessageHandler();

or use static in your inner class

hope that's help
