[已回复] MobileIMSDK android版用服务端向客户端发消息失败
使用MobileIMSDK android,用服务端向客户端发消息失败,调用的是ServerLauncherImpl.sendData(0, from_user_id, "json数据",true);
有遇到过的吗?

看样子你改过源码,而且出错的原因很明显,应该是有什么地方改动的不对。

你可以描述一下你大致改动了什么代码,如果能把改动的代码跟原先的代码作一个比对截个图发出来,一看就能明白了。MobileIMSDK官方原版是一定可以用服务端API发送消息给指定客户端的,不然要这个sdk有何用。所以,优先检查你改过的代码

这套代码本来是PC上的,现在是把它移到了android上面来,也就是在手机上搭建了这个服务器,肯定是删掉了很多东西的,在看看吧。。。现在也不知道为什么是null。。

这个是这样的,我把这个服务端,移植到了Android 上,我们有项目需要用到这个类似的推送。android 上由于没有java.awt.event.ActionEvent  和java.awt.event.ActionListener 的支持,我把这里的东西都注释掉了。

无论如何,这个QoS类也只跟消息送达保证有关,而你的代码是在服务端数据接收时就出错了,所以目前的问题可先不管这个QoS类。像这个空指针错误一定是一个非常明显的低级问题,你把源码里的异常栈打印出来,在Android上是:Log.d(TAG, e) 这样的日志输出就可以

这个不是收数据的时候报错的,是发数据的时候报错的。。。。我看了一下和你源码里面的改动基本上不会影响到这里。日志就是最上面的日志了。
或者我要怎么弄一下日志打印给到你?

这日志根本看不出什么,你要找到出问题的那段代码,针对出问题的代码再作分析。
