Socket.io android java client receiving messages and sending file example -

does have sample code demonstrates receiving messages on java client side socket.io?

also, there illustration on sending file/binary/picture on same socket.io java client? (basically sample code java instead of javascript client)

the version of android java client can acquired here (this version claim can used socket.io 1.0 , later) (seems updated version) https://github.com/nkzawa/socket.io-client.java

currently sample code allows me initialize connection, server able incoming connection event , java socket.io client able send out basic emit message. however, there no plain simple examples on how acquire message update server broadcast or emits website user.

sample code reference:

thanks reading

hy not sure if u looking for, , there might chance have solved it, regardless reply when browsing solution problem, came across question here couldnot find answer, left me disappointed. have solved problem, share how did it.

my problem was receiving message node.js server see message in logcat , having problem print message on android application in main ui thread.

lets say, show message received server in list view.

try { socket = io.socket("http://192.168.1.10:3000"); } grab (urisyntaxexception e) { e.printstacktrace(); } socket.on(socket.event_connect, new emitter.listener() { @override public void call(object... args) { log.d("activityname: ", "socket connected"); // emit want here server socket.emit("login", some); //socket.disconnect(); } // emit server }).on("somefunction", new emitter.listener() { @override public void call(object... args) { // argas[0] can have type send server jsonarray obj = (jsonarray) args[0]; string message = obj.tostring(); // runonuithread needed if want alter in ui thread runonuithread(new runnable() { public void run() { // //mlistdata array adapter mlistdata.add("serversays" + " : " + " " + message); mlistdata.notifydatasetchanged(); lvlist.setselection(mlistdata.getcount() -1); } }); } }).on(socket.event_disconnect, new emitter.listener() { @override public void call(object... args) { log.d("activityname: ", "socket disconnected"); } }); socket.connect();

we can update views main thread. have move portion of background task updates ui onto main thread.so have add together next , our required task in there.

runonuithread(new runnable(){ @override public void run() { //do } }

hope save time someone.
