1、 过滤日志
a.在你的 Android Studio 的 logcat 中输入 RongLog
b.选择 No Filters
2、排查链接日志
D/RongLog: [ RongIMClient ] [connect] ConnectRunnable for connect //准备链接
D/RongLog: [ RongIMClient ] initMessageReceiver
D/RongLog: [ RongIMClient ] onServiceConnected mConnectionStatus = DISCONNECTED // connect 前的链接状态
D/RongLog: [ RongIMClient ] onStatusChange : cur = DISCONNECTED, to = CONNECTING, retry = 0, cfg = 10 //开始链接，链接状态变化，有 disconnected-> connecting
D/RongLog: [ RongIMClient ] [connect] connect // 执行 connect 方法进行链接
D/RongLog: [ RongIMClient ] [connect] ConnectRunnable do connect!
I/RongLog: [ RongIMClient ] in Foreground //应用在前台
D/RongLog: [ RongIMClient ] [connect] callback onComplete //connect 成功后的回调
D/RongLog: [ RongIMClient ] onStatusChange : cur = CONNECTING, to = CONNECTED, retry = 0, cfg = 10 //链接成功后的状态变化，有 connecting → connected
3. 排查收发消息日志
收消息：
I/RongLog: [ RongIMClient ] onReceived : CSc3wbccmZKJowcYkhQ8DB RC:SRSMsg, 7 7, sender = LrkbEaEU5WCuo47MKiU82G, uid = B58M-RPQ3-AMG1-QC4E // 接收到消息：消息的 targetID，消息类型，发送人
发消息：
08-17 10:45:58.835 10464-10464/? D/RongLog: [ ConversationListFragment ] Message: RC:TxtMsg 8096 PRIVATE SENDING //会话列表显示正在发送的消息：消息类型，消息 id，会话类型，消息状态
08-17 10:45:58.835 10464-10464/? D/RongLog: [ ConversationFragment ] Event message : 8096, RC:TxtMsg, SENDING //会话界面显示正在发送的消息：消息类型，消息 id，会话类型，消息状态
08-17 10:45:58.853 10523-11216/? D/RongLog: [ NativeClient ] sendMessage code = 0, id = 8096, uid = B58N-3723-JHS1-QC4E RC:TxtMsg //消息发送成功后的回调：0代表成功；id 代表该消息在数据库中的索引，必须大于0；uid 代表消息唯一 id；
4. 排查推送配置日志
