问题
i am trying to develop a chat app, everything is working fine when internet is stable. like i can send and receive messages. but when the internet goes off for a while xmpp closes the connection. when internet comes back i am trying to reconnect to server. after successful reconnection i got the Stream error of Client already logged in and connection is automatically closed.
Here is my Broadcast receiver code to check Internet connection.
networkReceiver = new BroadcastReceiver (){
@Override
public void onReceive(Context context, Intent intent) {
//super.onReceive(context, intent);
if(intent.getExtras()!=null) {
NetworkInfo ni=(NetworkInfo) intent.getExtras().get(ConnectivityManager.EXTRA_NETWORK_INFO);
if(ni!=null && ni.getState()==NetworkInfo.State.CONNECTED) {
enableChat();
}
}
else if(intent.getExtras().getBoolean(ConnectivityManager.EXTRA_NO_CONNECTIVITY,Boolean.FALSE)) {
disableChat();
}
else{
disableChat();
}
}
};
here is the code for enabling chat and disabling chat.
public static void disableChat() {
msg_edittext.setClickable(false);
sendButton.setClickable(false);
form.setClickable(false);
msg_edittext.setEnabled(false);
sendButton.setEnabled(false);
form.setEnabled(false);
showNoInternetView();
if (xmpp.getConnection()!=null)
xmpp.getConnection().disconnect();
}
public static void showNoInternetView() {
linrNoInternet.setVisibility(View.VISIBLE);
msgListView.setVisibility(View.GONE);
}
public static void showInternetView() {
linrNoInternet.setVisibility(View.GONE);
msgListView.setVisibility(View.VISIBLE);
}
public static void enableChat() {
msg_edittext.setClickable(true);
sendButton.setClickable(true);
form.setClickable(true);
showInternetView();
msg_edittext.setEnabled(true);
sendButton.setEnabled(true);
form.setEnabled(true);
xmpp.connect("reconnect..");
}
while trying to reconnect the error log it shows is..

So, if anyone knows the process of proper reconnection please help me. i have searched for this question but i haven't got the solution yet.
thanks :)
回答1:
That is a known bug in Smack: SMACK-725.
Note that I don't recommend using ReconnectionManager on Android. Instead I suggest to implement your own reconnection logic tailed for a mobile environment and exploiting the information Android provides (e.g. listening for the CONNECTIVITY_CHANGED intent).
