ReconnectionManager in asmack

I have a project on Android, which needs to use asmack library to enable real time chat.

The key feature is reconnecting mechanism, that means my application can reconnect automatically whenever the internet connection loses.

Here is my code snippet:

ConnectionConfiguration connConfig = new ConnectionConfiguration(HOST, PORT);
connConfig.setSASLAuthenticationEnabled(true);
connConfig.setReconnectionAllowed(true);
XMPPConnection connection = new XMPPConnection(connConfig);

But I got this error whenever I turned off then turned on Wifi:

Anyone, who can solve this error, please help me!

When setting up everything at the start, call

ReconnectionManager.setEnabledPerDefault(true);

Then connections created from then on will automatically reconnect.

Use the latest smack api - I am using 4.1.0

Then set up re-connection like below:

ReconnectionManager manager = ReconnectionManager.getInstanceFor(connection);
manager.enableAutomaticReconnection();

It will automatically re-connect as described Here

Asmack is supporting Re-connection properly, only problem is that You are using SASL Connection so this is giving problem for because you are trying same connection again on turn Wi-Fi off.Try with set SASL false 

connConfig.setSASLAuthenticationEnabled(false);

required other wise disconnect manually

connection.disconnect();

Don't use reconnection mechanism which is implemented in ASMACK.

Use:

    connConfig.setReconnectionAllowed(false);

Instead, you should create BroadcastReceiver which listens to ConnectivityManager.CONNECTIVITY_ACTION. When connection to WIFI or other network is occurred, then you will receive the callback onReceive in your BroadcastReceiver.
