[android-developers] Re: Not able to receive UDP Data
UDP works well on emulators and devices. DatagramSocket socket = new DatagramSocket(port); byte[] data = new byte[1000]; DatagramPacket datagram = new DatagramPacket(data, 0, data.length, null, 0); socket.receive(datagram); On 18 мар, 03:20, Miguel Morales therevolti...@gmail.com wrote: I've read people on the internet recommending to use UDP for game networking on Android.

Re: [android-developers] Re: Not able to receive UDP Data
Can you verify this works on a device through a regular carrier signal and not through wifi? On Fri, Mar 18, 2011 at 1:34 AM, emymrin emym...@gmail.com wrote: UDP works well on emulators and devices.

[android-developers] Re: Not able to receive UDP Data
It worked when I did it with my G2 on T-Mobile. It worked with either one of WiFi or 4G (the carrier's data). But I said to debug on WiFi first, since there you have greater control and transparency: you can run Wireshark and see configuration on more points in the network. If you root your phone, you can even run tcpdump on the phone.

Re: [android-developers] Re: Not able to receive UDP Data
Great, it's been a while since I played with it because I implemented a reliable and good enough tcp solution. I'll revisit this if necessary to improve performance, hopefully this helps the OP resolve his problem. I was worried that some carriers would not allow UDP to phones, I'll still have to think of the balance between reliability and performance. Thanks.
