MongooseIM Android Client Network Transition Stability Guide

MongooseIM Android clients experiencing disconnections during 5G/WiFi network transitions require a comprehensive approach combining optimized server configuration, robust client implementation, and proper XMPP protocol usage. [Esl](https://esl.github.io/MongooseDocs/latest/getting-started/Quick-setup/?& !network.equals(previousNetwork)) { // Network changed - force XMPP reconnection xmppManager.forceReconnect("Network transition detected"); } previousNetwork = network; }

    @Override
    public void onLost(@NonNull Network network) {
        if (network.equals(previousNetwork)) {
            xmppManager.handleNetworkLoss();
            previousNetwork = null;
        }
    }
    
    @Override
    public void onCapabilitiesChanged(@NonNull Network network, 
            @NonNull NetworkCapabilities capabilities) {
        boolean hasInternet = capabilities.hasCapability(
            NetworkCapabilities.NET_CAPABILITY_INTERNET);
        if (hasInternet && !xmppManager.isConnected()) {
            xmppManager.scheduleReconnect();
        }
    }
}

### Handling Android Doze mode and background restrictions

Android's aggressive power management affects XMPP connections. [Android Developers](https://developer.android.com/training/monitoring-device-state/doze-standby?& connection.isAuthenticated()) {
            try {
                Message message = new Message(JidCreate.from(to), Message.Type.chat);
                message.setBody(body);
                connection.sendStanza(message);
            } catch (Exception e) {
                messageQueue.queueMessage(to, body);
            }
        } else {
            messageQueue.queueMessage(to, body);
        }
    }
    
    private void handleNetworkChange() {
        if (connection != null && connection.isConnected()) {
            connection.instantShutdown();
            scheduleReconnection();
        }
    }
    
    private void scheduleReconnection() {
        long delay = backoffReconnector.getNextDelay();
        if (delay == -1) {
            Log.w("XMPP", "Max reconnection attempts reached");
            return;
        }
        
        Handler handler = new Handler(Looper.getMainLooper());
        handler.postDelayed(() -> {
            try {
                if (!connection.isConnected()) {
                    connection.connect();
                    connection.login();
                }
            } catch (Exception e) {
                Log.e("XMPP", "Reconnection failed", e);
                scheduleReconnection();
            }
        }, delay);
    }
}
