无法从粘性服务android维护持久的XMPP连接
环境:为了不间断地从一对一/一对多设备传递消息,我让XMPPService作为粘性服务在后台运行。 为了接收消息,我有一个PacketListener,每当数据包到达设备时就会触发它。我使用asmack库进行客户端实现,并使用OpenFire作为我的XMPP服务器无法从粘性服务android维护持久的XMPP连接,android,xmpp,android-service,smack,asmack,Android,Xmpp,Android Service,Smack,Asmack,环境:为了不间断地从一对一/一对多设备传递消息,我让XMPPService作为粘性服务在后台运行。 为了接收消息,我有一个PacketListener,每当数据包到达设备时就会触发它。我使用asmack库进行客户端实现,并使用OpenFire作为我的XMPP服务器 public class XMPPService extends Service implements INetworkReceiver { private XMPPConnection mXmppConnection; privat

问题:当设备保持空闲一段时间时,设备与XMPP服务器断开连接,连接变为空,这违反了XMPP协议的规范,该协议规定XMPP服务器在我们强制注销之前保持与设备的持续连接。连接变为空的原因未知。当连接变为null时,PacketListener停止工作
我所做的一切:
