How to keep a XMPP connection stable on Android with (a)smack?

Actually There is not any problem with Reconnection manager. First you need to add connection listener to your connection manager.

connection.addConnectionListener(new ConnectionListener() {                    @Override                    public void reconnectionSuccessful() {                        Log.i("","Successfully reconnected to the XMPP server.");                    }                    @Override                    public void reconnectionFailed(Exception arg0) {                        Log.i("","Failed to reconnect to the XMPP server.");                    }                    @Override                    public void reconnectingIn(int seconds) {                        Log.i("","Reconnecting in " + seconds + " seconds.");                    }                    @Override                    public void connectionClosedOnError(Exception arg0) {                        Log.i("","Connection to XMPP server was lost.");                    }                    @Override                    public void connectionClosed() {                        Log.i("","XMPP connection was closed.");                    }                }); 

if any error occurred the connectionClosedOnError(Exception arg0) will automatically called when connection is closed

 public void connectionClosed() {                        Log.i("","XMPP connection was closed.");                        //You can manually call reconnection code if you                  want to reconnect on any connection close                    }

then check it this will call reconnectingin() method and try to reconnect.

Hope so this will help you.

use below code for check connection PingManager pingManager = PingManager.getInstanceFor(connection); pingManager.setPingInterval(5000);

add listner for ping fail handling to handle connection is connected or not because isConnected method is not reliable for check state of connection.

pingManager.registerPingFailedListener(PingFailedListener);

For mobile network connectivity is very big problem so you need to check network connectivity for mobile using broadcast receiver and on data reconnection you can use pingMyServer method to check connection is alive or not, if you are getting ping reply from server, means connection is alive otherwise on ping fail you can reconnect connection manually.
