Are there any good libraries or tools available for adding wifi multiplayer functionality to an Android game?The amount of work and cost involved for getting even the simplest of turn based multiplayer features into our games is somewhat daunting.

I have to develop a multiplayer game. The game will be supported between different platforms: 1) Two android clients. 2) Android client and a web application (something like facebook and android client for Texas- Holdem game).
I want to handle the communication between the platforms through a service.
I have asp.net (C#) background so I thought to implement the communication using WCF service but I am not sure this is the best choice?! Can you please tell me if my choice is good or should I choose other approach to implement the communication?
I am getting started in android development and I really want to create some form of online game. My goal is to start out with a turn- based game and move onto advanced multiplayer games. I want to have users associated with their google account, provide some sort of matchmaking to pair people together, have their stats stored in a database, and use the stats for various leaderboards and such. I have read over an older discussion on this list at http://www.mail-archive.com/android-developers@googlegroups.com/msg75... . There was a lot of good information that I gathered but I still have some questions. What I have so far is an apache web server on a laptop that I don't need right now (2.0Ghz Core 2, 3GB Ram).
I have never really used Java (although I'm learning it for android), but I know C/C++, Perl, and Python. I am in the process of learning mysql databases, which will help with a lot of the stats features I want to implement. I have built a HTTP/1.1 persistent server in C before which did JSON parsing and used a threadpool so I am somewhat familiar with the low-level network calls needed. However, I'm thinking that a free server software must exist that would offer more security and better load-balancing than the server I created. One solution I am thinking is to just use the Apache web server, have android make a request to a perl module I create on the server, and then have the server look it up on a database and so forth. Then the server will just keep sending back the player locations or whatever. Will the Apache web server slow me down for what I am trying to do or I am looking at everything the wrong way? Are there some settings in Apache that I could tweak to give me better latency such as persistent connections?
I am developing a multiplayer game on android. I am having a Java server and android client. The android client issues multiple requests and receives responses from the server. However the performance is not smooth. At times the data received at the Java server is not what I send from android. It is junk or zeroes. However, some times, data is correctly received.
I was wondering is there any data loss in between and why? I am using java.net on both ends. Please let me know if anybody was facing a similar problem anytime during android development.
Mages is multiplayer client/server game engine for Android and other mobile devices (currently Android and J2ME devices are supported, development for Windows Mobile in the progress). It allows developers to create internet multiplayer games by implementing only core game logic and GUI by using powerful engine API.

I'm wanting to add 2 player mode to a game, but I want this mode to be able to run over the internet.
My idea is to setup a game state server that would maintain information on the moves made or current game state.
The game clients would send information to this server and request updates via xml.
I would just like to know if this is the best way / only for to clients to send game information to each other over the internet? Any advice on this would be good.
I'm developping a simple realtime action game 4 Android. It works nice. but now i want deal with animation FPS and i'm facing a big problem i can't solve since couple days now.
I started from the famous Lunar Android sample using facebook. got 55-60 frame per second on my G1. it smelt good for my game i thought ... BUT when i plugged the surface view in my game i got a poor 6-9 Frame per second making the game unplayable.
After debugging removing all content of my doDraw used by the thread controlling the surface view i found the problem.
The problem is not the quantity of sprites i displayed but the concurrency between threads used for receiving my game data over TCP and the UI thread i use to control surface view.
If when i start displaying the game i stop the my socket protocol threads (reader, writer) the game is refreshed at 25 FPS which is not 50 FPS but large enought to make the game playable.
So my question is how in realtime game for android i can send / received data (and not delayed of course) without killing the game refresh rate.
Last thing i use canvas and not open gl but i don't need open gl and i really see the problem comes from the multithreading.
I am an android developer and I made some board games. Now i want to make some of my board games multiplayer. I don't want to create and host my own web service, so i thought about P2P.
The first thing i found was the XMPP protocol, however it's not real P2P, but if i can use the existing google talk service, i'm ready to go. Is this possible while using your existing google account without interfering with the normal working of your google talk client?
Then i heard about JXTA, a real P2P solution, and it's already ported from J2ME to Android (http://code.google.com/p/peerdroid/).
Maybe i am overcomplexing things here (as i do sometimes)
I just want to know the easiest way to do simple P2P for a boardgame.

Wordfeud - multiplayer word game for Android
Galcon, previously a PC game, has now been released on Android!
It's $3 and you can play it both single-player and multiplayer. It's pretty fun. Matches are over fairly quickly so it's good to pick up and play for a couple minutes.
The game works fine on my Droid X, but there seems to be an issue with Swype and the text input boxes. You can't Swype to type--instead, you have to tap each letter. Also, you can't seem to delete using Swype. Also, there is a bug where the number 0 won't register in the text box. These are pretty minor issues since entering your username and password is about the only typing you'll do in this game, but it's something to be aware of.

I'm working on a simple game to experience the multiplayer game development on mobile plaforms especially on Android and iOS. I'm now planning network/multiplayer side of the game and need some advice.
Firstly i think about Google App Engine as the server side of the game. But i learned that app engine cannot connect directly to clients. So updates of the users cannot be send to others directly with this method. Then i started to think about serving the game on one of the gamers of the current session. But of course some of the features will be on the server. You think it is a good idea?
Second, I'm looking for a protocol to communicate iOS and Android. YAML and JSON are the ones i looked so far.
Any other suggestions about multiplayer game development would be appreciated. Thanks...

My question is how can i do device to device connection in android using sets of api which can be :
1.Bluetooth - whose APIs are not currently available.
2.gtalkservice - removed from sdk1.0 3.wifi - I dont knw how to connect 2 devices using wifi apis . I have asked about wifi because we have developed a game on iphone which used wifi connection for multiplayer stuff.
Or is there any other apis which can be used for implementation of multiplayer in game ?
I have a square grid, for a turn based game ( grid is similar to the chess board ), but the moves in the games are different based on whether you have lapped your opponent pawn at least once or not.i.e if you have not lapped (beaten any of the opponents pawns) in the outer most grid as below.if you have lapped your opponent pawn once at least, then you get to reach home,this way.Any player having all his pawns reaching "home" first wins.The ones in yellow are safe-houses, i.e both the opponent pawn and the player's pawn get to stay in the same grid, this is not considered to be lapping ( the opponent ).The lapped pawn will return to its start point.Now the question is, what is the effective way to store the paths for the all the pawns.we will have 4 pawns for the player and 4 opponent pawns.Is there any pattern to store such static information, in a elegant way?

For example when someone exits I want them to be able to save and exit, then come back and click continue to pick up where they left off with all of the graphics in the right place, timer and score. I looked at onSaveInstanceState android examples, but not sure if this is what I need or how to implement it in my case.

I plann to create application is a real time multiplayer multiple choice game. It will have a pool of approximately 600 questions that will be randomly selected for every game. Games will start on a rolling basis, consisting of 10 players at a time who must answer 20 questions per game, for quetion and logic for game it's ready , now my main part multplayer , what i need exactly:
1. Player has to choose a room from the lobbay to enter a game.
2. The player waits until thier selected room reaches 10 people. at that point, the game will start.
3. within the game, each player's score update it in real game.
4. you can click name of player to take you to that player's stats page.
i need this in android but i don't now how i can stat and what the tool i need for it , as i menstion up the logic for application ready but i need multplayer part.
so do you know of any interesting multiplayer android games that work through bluetooth?

Fixes problems with handling of library project names that contain characters that are incompatible with the Eclipse path variable. Now properly sets up the link between the main project and the library project.
I create the library (foolib - no spaces, no caps, no punctuation). So far so good. I go to the main project, go to preferences --> Android. In the library box I add the new library. It appears. I press Apply. I press OK.
Nothing happens.
I return to the preferences, the library is no longer there JUST LIKE BEFORE.
I looked around for info on this in the group but couldn't find any... so far in my OpenGL programming I've just done everything directly, but I was curious if anyone had written any "wrapper" libraries for it besides min3d. Min3d is great (or is getting there) but it's GPL'd, making it unsuitable for a commercial product (if my understanding of the license is correct).
View 5 Replies View RelatedWe have been using gdbserver to debug our JNI code as follows. We have been less than successful -- breakpoints do not always get activated, sometimes we get SIGILL, and we seldom ever get a useful stack when the debugging stops on SIGSEGV, sometimes the program dies with SIGTRAP!!!
We have occasionally been able to have debug sessions with s/n, but since pretty much every SEGV has resulted in either a damaged stack, or at least, gdbserver can not find the stack, it's a pain.
Is there something we are missing? Is there some reason to use the 4.2.1 vs 4.3.1 toolchain? (Why are there two toolchains? I assume because of bugs in each that are fixed in the other... which bugs?)
We guessed that the "dalvik" process that we wanted to debug was app_process --- we found this out by looking at /proc/XXX/cmdline on our running activity.
This is what we do typically do(repo sync directory is in /build/m1 for me)
invoke:/build/m1/prebuilt/linux-x86/toolchain/arm-eabi-4.2.1/bin/arm-eabi- gdb
(some of us use -tui, some of us run it under Xemacs, etc.)
We then do:
CODE:..........
We then start our activity, adb shell, discover the PID of the activity, discover the IP of the phone with "netcfg", and:

This is with a physical device. With an emulator, one has to, of course, run the adb forward stuff. (Too bad that doesn't work with a real device too, as then I would not need to run gdb over the wireless)
