【问题描述】：
我正在尝试使用 pusher-java-client1.2.1 库连接到 android 中的 pusher，我的连接代码如下所示
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 及以上版本中运行良好，但在 android 4.4 应用程序崩溃并出现以下 logcat 输出

任何人都可以建议我解决这个问题

这对我来说似乎是 MultiDex 问题。您的应用程序的
build.gradle中有multiDexEnabled true行，并且您的Application 类没有扩展MultiDexApplication？顺便说一句，pusher-java-client 的最新版本是 1.4.0 -
@zmarkan 我的应用已经启用了 multidex
