I am working on chat application and using ejabberd
saas edition as xmpp server for it. I am using smack library ver-4.2.3. To keep connection alive I am using ping manager. Here is the code I am using:
ReconnectionManager.getInstanceFor(AppController.mXmpptcpConnection).enableAutomaticReconnection();
ServerPingWithAlarmManager.onCreate(context);
ServerPingWithAlarmManager.getInstanceFor(AppController.mXmpptcpConnection).setEnabled(true);
ReconnectionManager.setEnabledPerDefault(true);
//int i = 1;
// PingManager.setDefaultPingInterval(i);
PingManager.getInstanceFor(AppController.mXmpptcpConnection).setPingInterval(300);
I am using sticky-service also for connection, but when I keep my application open (ideal-state) for 15-20 mins then the connection is lost, so I am using ping manger to resolve this issue.
Is there any other better way of doing it or ping manager is the only option?
Insted of pinging chat server constantly, you better to use ConnectionListener()
in smack library. You need to use something like this:
XMPPTCPConnection connection;
// initialize your connection
// handle the connection
connection.addConnectionListener(new ConnectionListener() {
@Override
public void connected(XMPPConnection connection) {
}
@Override
public void authenticated(XMPPConnection connection, boolean resumed) {
}
@Override
public void connectionClosed() {
// when the connection is closed, try to reconnect to the server.
}
@Override
public void connectionClosedOnError(Exception e) {
// when the connection is closed, try to reconnect to the server.
}
@Override
public void reconnectionSuccessful() {
}
@Override
public void reconnectingIn(int seconds) {
}
@Override
public void reconnectionFailed(Exception e) {
// do something here, did you want to reconnect or send the error message?
}
});
Yes, There is. Few points before the solution
Build.VERSION_CODES.O
BOOT_COMPLETED
intent action and starting this foreground service from receiver.google-volley
for making connections and even you can communicate using it.For communication :
StringRequest stringRequest = new StringRequest(Request.Method.POST, "https://oniony-leg.000webhostapp.com/user_validation.php",
new Response.Listener<String>()
{
@Override
public void onResponse(String response)
{
serverKeyResponse = response;
// get full table entries from below toast and writedb LICENSETABLE
//Toast.makeText(getActivity(),response,Toast.LENGTH_LONG).show();
showKeyResponse();
// Log.d("XXXXXX XXXXX", "\n SUCCESS : "+serverKeyResponse);
}
},
new Response.ErrorListener()
{
@Override
public void onErrorResponse(VolleyError error)
{
serverKeyResponse = error.toString();
// show below toast in alert dialog and it happens on slow internet try again after few minutes
// on ok exit app
// Toast.makeText(getActivity(),error.toString(),Toast.LENGTH_LONG).show();
showKeyResponse();
//Log.d("YYYYYY YYYYYY", "\n FAILURE : "+serverKeyResponse);
}
})
{
@Override
protected Map<String,String> getParams()
{
Map<String,String> params = new HashMap<String, String>();
params.put("INPUT",LicenseKey.getText().toString());
params.put("USER", MainActivity.deviceid);
return params;
}
};
RequestQueue requestQueue = Volley.newRequestQueue(getActivity());
requestQueue.add(stringRequest);
You just have to reply ECHO "SUCCESS"
from server using a php ( or whatever server side language you like ). In response check for SUCCESS
presence, any any other cases.., Use other KEYWORDS YOU LIKE. You can handle Server response errors too
. Even you can communicate from android in request - response handshake. But you have to implement few handshake on your own.
I Hope, It helps...
Best way to keep the alive connection with XMPP server you should reconnect after every network change.
Like this:
public class NetworkStateChangeReceiver extends BroadcastReceiver {
private Context context;
private static NetworkStateChangeListener mListener;
@Override
public void onReceive(Context context, Intent intent) {
this.context = context;
try {
if (!ApplicationHelper.isInternetOn(context)) {
if (mListener != null) {
mListener.OnInternetStateOff();
}
return;
} else {
XMPPTCPConnection xmpptcpConnection = XmppConnectionHelper.getConnection();
if(!StringHelper.isNullOrEmpty(new SessionManager(context).getAuthenticationToken())) {
Intent XmppConnectionServicesIntent = new Intent(context, XmppConnectionServices.class);
context.stopService(XmppConnectionServicesIntent);
context.startService(XmppConnectionServicesIntent);
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
//to initialize NetworkStateChangeListener because null pointer exception occurred
public static void setNetworkStateChangeListener(NetworkStateChangeListener listener) {
mListener = listener;
}
}
Use the ReconnectionManager class as described here .
ReconnectionManager manager = ReconnectionManager.getInstanceFor(connection);
manager.enableAutomaticReconnection();
It will automatically re-connect when necessary.
