I'm trying to communicate to my nodejs application using android as client. Currently I'm using https://github.com/Gottox/socket.io-java-client repository as reference. Tried the examples of repo but no help.
NodeJS-SocketIO Code:
socket.on('new user',function(data, callback){
if (nicknames.indexOf(data)!=-1){
callback(false);
} else{
callback(true);
socket.nickname = data;
nicknames.push(socket.nickname);
updateNicknames();
}
});
Android-Java Code:
try {
JSONObject json = new JSONObject();
json.putOpt("data", "user1");
socket.emit("new user", json);
} catch (JSONException ex) {
ex.printStackTrace();
}
However, the above code results in TypeError: undefined. Please help. Thanks in advance!
You can do away with the JSON object
. You could just do:
socket.emit("new user", "user1");
Not so sure about sending a JSON over, but if you wanted to, did you try:
JSONArray array = new JSONArray();
array.put("data", "user1");
socket.emit("new user", array);
Pretty sure JSONs need to have the enclosing brackets.
