I'm sure there is a similar question somewhere on here but I just can't seem to find it.
Here's what I'm trying to do.
let's say I am connected to a server and I want to disconnect from it if no calls are made by the user in last 5 minutes. BUT, if even a single call is made, the 5 minute timer would reset and countdown to 5 would start again..
It seems simple but I am kind of new to Android and trying to figure things out..
thanks in advance!
======= EDIT
So here's an example of code of what I want to do.
try {
client.publish(topic, message);
success = true;
if(topic.equals("response")) {
// need to reset my 5 min timer here
// but if 5 mins go by and this try/catch isn't called again,
// need to call the client.disconnect() method here
} else {
client.disconnect();
}
} catch (Exception e) {
success = false;
e.printStackTrace();
}
so basically that gets called every time there is a call to the server.
What do i need to implement in the if statement?
================= EDIT AFTER ANSWER @Saeed Mashhadi's answer
Please see the following log output. So at first, it worked fine. and When the disconnectCounter was increasing by one every second, I made another call.
after that call, disconnectCounter started at 1 again but it started increasing by 2 every second. There are timestamps on the left. can you please tell me why this is happening?

Thanks you!!
You can do something like this:
Timer timer;
...
try {
client.publish(topic, message);
success = true;
if(topic.equals("response")) {
// If try/catch is called, counter resets
disconnectCounter=0;
timer=new Timer();
timer.scheduleAtFixedRate(new TimerTask() {
@Override
public void run() {
// Increase counter every second
disconnectCounter++;
Log.i("counter", disconnectCounter + "");
// If 5 mins go by and this try/catch isn't called
// again, disconnect
if(disconnectCounter==300){ // 300=5*60
client.disconnect();
timer.cancel();
disconnectCounter=0;
}
}
}, 1000, 1000);
} else {
client.disconnect();
disconnectCounter=0;
}
} catch (Exception e) {
success = false;
timer.cancel();
disconnectCounter=0;
e.printStackTrace();
}
