Hi.

Today I reinstalled my JBuilder8. After that I installed JMobileSet 3 and finally the new Nokia Developer Suite 2.0.

Now I get this weird error message when I compile my project:...

There is no float type in J2ME. But there are libraries that implement common floating point operations using only integers. One of them is MathFP which can be downloaded from...

I think you should preverify your JAR file after you have obfuscated it. Personnally I use Proguard and if I remember correctly I had similar problems with it.

So you should give a command like...

Thanks for your advice but I'm still having the same problem. Your advice seemed very sensible though and I think it might be the solution to my problem.

Could you give me an idiot proof...

I have some problems when I try to download my midlet over the air to my Nokia 3510i phone. For some time it tries to connect to the site and then I get a message "Response unknown" (in Finnish:...

Every time I try to close a java application (including the games that were included with the phone) I get a blue screen (just like in...

Hi.

As my project progresses it becomes more and more obvious that keeping the JAR size small enough is very difficult. I haven't done any special optimizing as this is the first time I really...

Hi.

I'm writing a game that needs to do a heavy initializing routine before every level. Now it would be nice to show some "please wait..." message to the user so that he knows that the program...

Thank you for your answers.

I had already optimized my images so that thing was taken care of. But I didn't know anything about obfuscators. That was a pleasant surprise :-) I downloaded...

Thanks again for your great advises but now I'm having a trouble using my obfuscator. If I try to run a obfuscated JAR file in my phone or in an emulator I get an application error: Error verifying...
