Java client API

[isahn]

Hi,

do you plan to release java client API (Android compatible) for X2, and if yes when?

Thanks

I am also anxiously waiting for the Java Client API. We need it for unit testing extensions without having to go through the game flash client. And we don't have the resources to build flash test clients to do that.

Can you at least give us an indication of when this will be released?

I don't care about an Android API. Just plain Java like there was for SFS1.6.

We should be ready in a couple of weeks.

@mka - you can meanwhile use the Unity / C# API for unit testing if thats your goal. Works perfectly fine standalone for exactly that purpose without a requirement for Unity itself.

[Lapo]

Yep, and if you work with a non-Windows OS I'd recommend Mono and MonoDevelop: http://monodevelop.com/

[adenault]

Any updates?

[Lapo]

Here's a preview version:

DOWNLOAD BETA 1

NOTES:
Currently doesn't support UDP
No Javadoc available yet, however uses same interface as the other languages so you can rely on AS3 docs or C# docs and the IDE autocomplete

Provided is a simple example exported as Eclipse project (zipped)
If you don't use Eclipse just unzip the src folders and the dependencies.

EDIT: we just released beta 2 version. Please check this post.

Thanks for your effort.

Anyone test this beta release?

It is a java version file but my project is written in android. So I convert it to a simple android test project and found 2 error.

1. Compile error happened when I first compile the code in eclipse as an new android project. The log4j jar cause heap size error. Well, I remember that android does not support log4j.

2. I remove the log4j jar and see what happen then. This time the project can be compiled but I get an runtime error. I get the verify error for the class log4j and then SmartFox. Maybe the first exception on log4j cause the second error, I guess.

So anyone have a try? I really wanta have a try on SFS2

[Lapo]

We use the slf4j API for logging so you should be able to switch logging API without too many problems.
You can go here:

download the libs and replace the log4j interface with the JDK logging ones.
I think...
We'll also check it out.

Not tested on Android - just standard java.

Any feedback otherwise is welcome and shoot away with questions!

thanks lapo and ThomasLund

After several try, I still can not run my android project.

I remove slf4j-api-1.5.10.jar and slf4j-log4j12.jar. Then download and add slf4j-android-1.6.1-RC1.jar into project. Here is my log. Actually the error is exactly the same as using the original slf4j*.jar files...

[ThomasLund]

Right - I got a hardcoded reference to log4j in there.

02-22 19:44:46.390: ERROR/dalvikvm(18416): Could not find method org.apache.log4j.Logger.getRootLogger, referenced from method sfs2x.client.SmartFox.<init>

Exactly that one.

I'll try to see if I can fix that one up without referencing log4j directly.

I'm using it in a pure Java project with no problem.

Cheers,

Alex

[ThomasLund]

Super Alex - thanks

The Android fix will require some changes to the API code. Will try to get to it today or tomorrow. No biggie - just am 3 days from releasing a 1 year in development game. So slightly stressed

Hi all!

Firstly thanks to Lapo for giving us the beta API. It's been a tremendous help so far.

I am using it in pure Java to test our custom extensions and event handlers. There are two things I have noticed so far:

1) The custom login does not work with the password check using the SFSApi like this:

Code: Select all

getApi().checkSecurePassword(session, clearTextPwd, sfsClientPwd)

The reason seems to be a different encryption mechanismn on both the java client and smartfox.
I worked around it by extending the provided client LoginRequest and overwriting the execute method like this:

Code: Select all

   @Override
   public void execute(SmartFox sfs)
   {
      super.execute(sfs);
      // overwrite the password with a case-insensitive version
      String pwd = sfso.getUtfString("pw");
      sfso.putUtfString("pw", pwd.toLowerCase());
   }

2) When adding SFSObject's to a UserVariable I have to explicitly set the variable type. Otherwise I get "Unsupport SFS Variable type".
So I have to do:

Code: Select all

ISFSObject obj= new SFSObject();
UserVariable var = new SFSUserVariable("varName", obj, 5);

instead of just:

Code: Select all

ISFSObject obj= new SFSObject();
UserVariable var = new SFSUserVariable("varName", obj);
