Apps Get json data on android client listener

[ware4u]

I have code socket io js like this

socket.on('clienstconnected',function(data

var roomlist={id:'1',roomname:'room1',id:'2',roomname:'room2',id:'3',roomname:'room3'};

socket.emit("clienstconnected",roomlist

});

and Android code like this

private Emitter.Listener onClienstConnected1 = new Emitter.Listener() {
@override
public void call(Object... args) {
JSONObject data = (JSONObject) args[0];

try{

System.out.println(args[0].toString());
}

catch (Exception e) { Log.e("My App", "Could not parse malformed JSON: \"" + data + "\"");}

}
};

and System.out.println print only one item is : id:'3',roomname:'room3' not all of Json item as I want

Thk for reading my topic

I added code tags to make your syntax more readable for folks that can help.

You need a loop. Try this (uncompiled, and untested)

private Emitter.Listener onClienstConnected1 = new Emitter.Listener() {
@override
public void call(Object... args) {
    JSONObject data = (JSONObject) args[0];
    try {
        for (int i=0; i < args.length; i++) {
            System.out.println(args[i].toString());
        }
    }
    catch (Exception e) { Log.e("My App", "Could not parse malformed JSON: \"" + data + "\"");}
  }
};

Can you show the stack trace output from your Logcat?
