android xmpp开发 asmack实现断线自动重连

http://blog.csdn.net/ming_light/article/category/1531703

asmack本身封装了断线重连机制，但是有一点需要注意

在设置链接属性钱，要加载ReconnectionManager这个类，否则没有效果。

直接上代码：

第一步

 try {
                     Class.forName("org.jivesoftware.smack.ReconnectionManager");
                 } catch (Exception e1) {
                 }

第二步   设置链接参数，启动重连功能

 ConnectionConfiguration configuration = new ConnectionConfiguration(
                 Contents.HOST, Contents.PORT);
         configuration.setReconnectionAllowed(true);

第三步   链接后注册监听

 connection.connect();
 if (connection.isConnected()) {

 connection.addConnectionListener(connectionListener);

                     }


 public static ConnectionListener connectionListener = new ConnectionListener() {

         @Override
         public void reconnectionSuccessful() {
             Log.i("connection", "reconnectionSuccessful");
         }

         @Override
         public void reconnectionFailed(Exception arg0) {
             Log.i("connection", "reconnectionFailed");
         }

         @Override
         public void reconnectingIn(int arg0) {
             Log.i("connection", "reconnectingIn");
         }

         @Override
         public void connectionClosedOnError(Exception arg0) {
             Log.i("connection", "connectionClosedOnError");

         }
