推送器在 android 4.4.4 中不工作

Question

我正在尝试使用 pusher-java-client1.2.1 库连接到 android 中的 pusher，下面给出了我的连接代码

 if(Utils.isOnline(mcontext)) {
        PusherOptions pOptions = new PusherOptions();
        pOptions.setAuthorizer(new HttpAuthorizer(Constants.PUSHER_AUTH_SRC_URL + "/auth.php"));
        pusher = new Pusher(Constants.PUSHER_KEY, pOptions);
        pusher.connect();

        channel = pusher.subscribe(Utils.getPref(mcontext, "channel_name", ""));
        Utils.setPref(mcontext, "OtherUserId", "");
    }else{
        Utils.setCustomToast(mcontext,Constants.NO_INTERNET,false);
    }

我的这段代码在 android 5.0 及更高版本中运行良好，但在 android 4.4 应用程序中崩溃并出现以下 logcat 输出

任何人都可以建议我解决这个问题

问题出在我使用的依赖项中 google-play-service google play service 和 pusher-java-client 是冲突的，所以我通过使用特定的依赖项解决了问题 google-播放服务-gcm
