【问题描述】：

当我关闭应用程序并停止执行 ping 时如何正确注销？

当我在下面运行注销时，每一行代码都可以正常工作，

但如果我运行代码行：

 Presence presence = new Presence(org.jivesoftware.smack.packet.Presence.Type.unavailable);
            presence.setStatus(connection.getUser() + status);
            connection.sendPacket(presence);

我让用户离线/不可用。//But the connection alive

然后我想断开连接，所以我运行线路代码。

connection.disconnect();//I get user online/available and connection die.

当连接中断时，我遇到了更多问题，例如 ping。

public void logOut(boolean unavailable, String status) 

    if (isConnectionAlive() || reConnectAndAuth()) 
        Presence presence = new Presence(org.jivesoftware.smack.packet.Presence.Type.unavailable);
        presence.setStatus(connection.getUser() + status);
        connection.sendPacket(presence);
        pm = null;
        connection.disconnect();
       //iscNNcet();
        Log.w("LogOut","LogOut");
    

【参考方案1】：

我通过下一个代码解决了这个问题。

public void logOut(boolean unavailable, String status,Context orgContext) 

if (isConnectionAlive() || reConnectAndAuth(orgContext)) 
    Presence presence = new Presence(org.jivesoftware.smack.packet.Presence.Type.unavailable);
    presence.setStatus(connection.getUser() + status);
    pm = null;

    try 
        connection.disconnect(presence);
     catch (Exception exception) 
        exception.printStackTrace();
        connection.disconnect();
    

    Log.w("LogOut", "LogOut");
