求助我的IM切换到4G网络时耗时几分钟才登录成功

代码改来改去，突然发现客户端切到4G网络时（无线网情况快速正常），需要很长时间才能登录成功。回溯版本已经不可能了，请教一下我应该从哪里下手？大概哪些地方？

Android log

首先，你给的日志完成看不出来你所描述的现象的过程，你抓Log也好歹也上点心，随便抓抓神也猜不出来啊。

另外，你的log里有一个异常，你没有注意到？

底层MobileIMSDK没有修改

你回忆一下：最近修改了哪些代码，然后可以把你认为有嫌疑的代码贴出来。

另外，客户端的log很关键：你可以把客户端log在Android Studio下清空一下后，当把网切到4G后直至登陆成功这段时间的所有log全抓出来，贴到本贴，一起分析分析。

注意：log里只要显示本APP的log，系统的其它Log就把它过滤掉，别弄个上午行log，有用的几有几行。。。

底层MobileIMSDK没有修改

你的意思是，你对MobileIMSDK代码做过修改后，当客户端从WiFi切换到4G后，程序需要几分钟才能登陆成功？
