i already inputted all the necessary parameters for it to work according to the docs and the forums but it just can't seem to work on me

private  void joinMeeting(Context context, String meetingNumber,String zak, String userName, String usID){
        int ret = -1;
        MeetingService meetingService = ZoomSDK.getInstance().getMeetingService();
        JoinMeetingOptions options = new JoinMeetingOptions();
        //JoinMeetingParams params = new JoinMeetingParams();
        //params.displayName=userName;
        //params.meetingNo =meetingNumber;
        //params.password=meetingPassword;
        //meetingService.joinMeetingWithParams(context,params,options);

        StartMeetingParamsWithoutLogin params = new StartMeetingParamsWithoutLogin();
        params.userId = usID; // Based on this id we are able to start the meeting as host
        params.userType = MeetingService.USER_TYPE_API_USER;
        params.displayName = userName;
        params.zoomAccessToken = zak; //getting the zoom access token from start_url
        params.meetingNo = meetingNumber; // meetingNo, getting this from create meeting api response
        ret = meetingService.startMeetingWithParams(context,params,options);
        Log.e("Start Meeting As Host", "===startMeetingWithNumber====ret=" + ret);
    }

i tried all generating more meeting using my web sdk but it wont work either
