XMPPError connecting to 10.0.2.2:5222
请问老师，我这边连接不上：
服务端配置：
jdbcUrl=jdbc:mysql://192.168.1.100:3306/androidpushserver
客户端的配置：
apiKey=1234567890
xmppHost=10.0.2.2
xmppPort=5222
但还是提示：XMPP connection failed
java.net.ConnectException: failed to connect to /10.0.2.2 (port 5222): connect failed: ETIMEDOUT (Connection timed out)
