Hold a Socket.IO Connection throughout Application while it in running foreground or background

Question

I have made my one to one and group chat application using socket.io , everything is working fine , but If I am interacting with UI it establish the connection but after some time when I stop interacting with the application then the connect break and user goes offline as I am not using any event for putting my user offline. Can anyone help me in this.

 public  SocketConnection() {
    {
        try {
            nSocket = IO.socket(Constants.NAME_SPACE);
        } catch (URISyntaxException e) {
            throw new RuntimeException(e);
        }
    }
}


public Socket getSocket(){
    return  nSocket;
}

this is where I am putting my user online.

 public class SplashActivity extends ActivityManagePermission {
    String permissionAsk[] = {PermissionUtils.Manifest_CAMERA
           , PermissionUtils.Manifest_WRITE_EXTERNAL_STORAGE
          , PermissionUtils.Manifest_READ_EXTERNAL_STORAGE
           };
     Context context = SplashActivity.this;
    private JSONObject mJson;
    SessionManagement session;
private Socket mSocket;
int SPLASH_TIME_OUT = 2000;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_splash);

    session = new SessionManagement(context);

    /**
     * Creating the socket connection.
     */
    SocketConnection obj = new SocketConnection();
    try {
        mSocket = obj.getSocket();
    } catch (URISyntaxException e) {
        e.printStackTrace();
    }




    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            askCompactPermissions(permissionAsk, new PermissionResult() {
                @Override
                public void permissionGranted() {
                    if(session.isSignedIn()) {
                        mJson = new JSONObject(); //creating json object
                        Object type = "M";
                        Object ID_USER = session.getUserDetails().get(SessionManagement.USER_ID);
                        try {
                            mJson.put("userId", ID_USER);
                            mJson.put("connection_type",type);
                        }catch (JSONException e) {
                            e.printStackTrace();
                        }

                        mSocket.emit(Constants.event_new_user_online,mJson.toString());
                        mSocket.connect();
                        Intent i = new Intent(context,HomeActivity.class);
                        startActivity(i);
                        finish();
                    }else {
                        Intent i = new Intent(context, LoginActivity.class);
                        startActivity(i);
                        finish();
                    }
                }

                @Override
                public void permissionDenied() {
                    Intent i = new Intent(context, SplashActivity.class);
                    startActivity(i);
                    finish();
                }

                @Override
                public void permissionForeverDenied() {
                    Toast.makeText(context,
                            "Please allow the permissions"
                            ,Toast.LENGTH_SHORT).show();
                    startActivity(new Intent(context,SplashActivity.class));
                }
            });

        }

    }, SPLASH_TIME_OUT);
}

}

You need to use Socket IO options.

IO.Options options = IO.Options()

options.setTimeout(60000L) // 60 seconds
options.setReconnection(true)

and then use it like this while making a connection.

nSocket = IO.socket(Constants.NAME_SPACE, options);
