Android / Java Networking

Sep 2, 2013

Been doing some android networking lately. Having some trouble actually sending the data back and forth.

Java -> Server (runs on the desktop): its job is to constantly listen on a port and connect clients. Once a client connects, it creates a new JFrame with a graphics class.(Basically a giant canvas) There is a separate thread that is always listening to the client.

Android -> Client: An android device is the client. Its job is to connect to the server, with a given IP/Port. Once the connection has been established, it changes (setView) the view to a canvas. On the canvas there is a box that moves based on touch input.

Objective: The box moves on the android screen, but it doesn't move in the JFrame window.

I think the information is not being relayed. I have tried dataOutputStream. But for some reason there is a major Lag in sending the information. (Not waiting for serverSocket) Basically i want a real time updates. As the box moves on the android device, it should also move on the JFrame.

Android :: Best Practice For P2P Handset Networking

Dec 4, 2009

I've been scouring the web looking for information on setting up a peer-to-peer connection between Android handsets and so far have drawn a blank. The only thing I can definitively seem to work out is that it was made a whole lot more difficult when XMPP was removed from 1.0. Apart from that, I find a couple of threads on an OpenIntents board about porting an XMPP implementation to Android that were last posted nearly 2 years ago. Has anybody solved this problem effectively? What's the best way of doing it (from a games point of view)?

Android :: Need Method For Phone Game Networking?

Oct 29, 2010

I need help finding the best method for networking in a multiplayer game. I want to connect to a phone and maintain the connection until the game is over, hosting the game on one of the phones. There are other threads, but none of them really explain how to connect or use the networking, only saying to use such-and-such library. Examples or links to good tutorials would be extremely helpful.

Android :: Enable/Disable Networking In Emulator

Sep 22, 2009

According to the emulator docs, you should be able to enable/disable networking with the F8 key. I doesn't work for me and I'm trying to determine why.

I'm developing on OSX Leopard. I've also tried in a virtual Windows instance (Windows 2008 server running in Parallels). No luck in either case.

I've tried the obvious stuff like fn + F8, etc.

Should there be any sort of visual cue that networking has gone online or offline when F8 is pressed?

Android :: Networking Stack / Unable To Reproduce Using An HTC ROM On My Personal G1

Aug 29, 2009

I've been working on a game for a while now that relies heavily on UDP connections. Its been running great, but since releasing in the market, we've been flooded by complaints from Hero users that it doesn't run what-so-ever. We haven't received this complaint from anyone other than Hero users (seems 100% isolated to the device), and I haven't been able to reproduce using an HTC ROM on my personal G1 (thought it might be related to the OS), but I'm starting to suspect it's a hardware issue...

Does anyone on the list have access to a Hero, and adb that I could ship an APK with a bit of extra logging to see exactly whats going wrong?

Android :: Emulator Networking - Maps Running In A Distributed Fashion

Aug 17, 2010

looking over the online guide for the emulator and after some googling i still have some questions on this - the guide focuses on emulator instances running on the same machine. However, I was trying to see how that maps for emulator running in a distributed fashion. If a node A (with IP address 129.10.52.x) in LAN A is running Emulator A (which will have the default IP address of 10.0.2.15:portA) wants to communicate with a emulator B (which will also have the default IP address of 10.0.2.15:portB) running on node B (with IP address 129.10.53.x) in LAN B how is the port forwarding setup in this case? The same way as if both emulator were running on the same machine? And why when I print the IP address of the emulator running on any of the nodes what's displayed is the loopback address 127.0.0.1 and NOT 10.0.2.15 which is the IP address that each emulator is assigned?

General :: USB Networking To VNC Over USB From Ubuntu 12.04

Aug 13, 2013

Well the script should be working, it is 'ettin.sh' now. To get VNC to work on separate device just change 'eth0' to 'wlan0' or whatever other interface you know how to configure, like usb maybe, in the 'init.sh' script that resides in ~/ on the images you can download from [URL]....

Also on the different roms your storage might be different so just change that to what suites your environment,

After my first launch and exiting the VNC on my laptop (Ubuntu) My phones home button and a few other functions stopped working, a reboot remounts the root and system partitions and it goes back to normal essentially, I haven't noticed any adverse affects after the reboot.

I want to connect to backtrack over usb from Ubuntu on my laptop instead of from my phone. Is there a good way of doing this?

The thing is, I didn't chroot, I mounted the image, copied the contents of '/etc/*' and '/sbin/*' to the '*/etc' '*/sbin' dirs of the mounted image. and then mounted it's (the image's) contents to Androids rootfs '/' then I set up a little script to set up the environment and execute '/bin/bash -i init.sh' and again reset PATH to include /system/*.

Then in the init.sh script I want to set up a way to 'vnc' through' usb to backt4acks desktop. How would I do this?

Android :: Writing Mobile Application - Connects Multiple Social Networking Sites

Jan 28, 2010

I need to write an Android application that allows a user to connect to multiple social networking sites like MySpace, LinkedIn, FaceBook etc. and fetch friends list.

I know that most of these applications have Java libraries or functionalities exposed as REST based WebServices. But since there is a lot of variety and disparity in the ways that these libaries are written or service that can be consumed, is there any single, integrated service or middleware component that I can use to provide a unified interface in my mobile application?

First, hi, new Hero owner (1 week now) and I love it.

Feb 7, 2012

I'm trying to set up a basic network connection using droids but I'm having problems.my server program:

Code:
ServerSocket ss = new ServerSocket(8888);
while(!end){
//Server is waiting for client here, if needed[code]....

Motorola CLIQ :: Kill All Networking Settings / Extra On Screen Buttons

Feb 20, 2010

While I understand the purpose of the CLIQ is its social networking aspects, I am thinking of buying this phone for my wife who does not use Facebook, etc. The reason for this phone is the keyboard, she is not fan of touch screen and I think the G1 is just too bulky. This brings me to my question: Is there a way I can kill all the networking settings and extra on screen buttons so it will be closer to the MyTouch that I have?

Motorola Droid X :: How To Change When Social Networking Widgets Sync Data?

I cannot for the life of me find any settings for this. I swear I've read about people setting theres to only do it every couple of hours or so to help with battery life but I can't find anything for this. The only thing I've managed to find is an option to set it to only sync over WiFi. Forgive me if this has already been asked but I couldn't find any answers to this dilemma.Oh and also, what exactly is considered "Background Data"? There's an option for enabling/disabling it and I wondered what the term encompasses.

That's array is sorted as attributes are declared in the main Class in sun jdk. For example, next Class is defined as: public class Example { public boolean stop; public int atr1; public String name; ....

Android :: Android / Java - Call Function In Separate *.java File?

Aug 16, 2010

I do an import of the full package name / java file, and if I do a <classname>.<method>, SOMETIMES I can get it to access - other times I get a lot of can't use a static in a non static bunch of talk. I'll admit I'm new to Java, so what do I need to do? Call a class instance first, then call my methods? I'm rather confused by this, as I want to put all of my 'functions' into a FunctionsList.java file, and all of my main Activity (UI) into a MyActivity.java file.

For example:
<MyActivity.java>
import com.example.FunctionsList;
private class MyActivity extends Activity {
FunctionsList.function();
}


9/10 times I get that static/non-static error. If I put all of my functions into MyActivity.java, I have zero problems!
