Running LWUIT-Demo on MicroEmulator on (jailbroken) iPhone

Hi!

I'm currently porting MicroEmulator (http://microemu.org) to jailbroken iPhones. I did a quick test with running LWUIT on it, and while it was very slow and had some graphic errors, it actually worked.

See some screenshots here:

I expect to get the performance better, but will try to correct the graphical glitches first.

Make it run, make it right, make it fast :)

There is not a public version of MicroEmulator in the Cydia repositories yet. I hope to have that soon.

I'd like to be one of the first to thank you *and* request fast jsr-184

Seriously... great job! I hear walls crumbling as we speak.

Good work :).

Although I have a question. If I remember well, there is no JVM available for iPhone. How can you port the MicroEmulator on iPhone then ?
Is there a JVM available for jailbroken iPhones ?

JamVM is available for jailbroken iPhones. It can be installed with cydia.

Additionally there is a ObjectiveC/Java binding available called JocStrap, that allows to interact with the iPhone high level UI elements like UIView...

For low level access I have created the straptease binding (http://code.google.com/p/straptease/), that gives access to the C-Frameworks like CoreGraphics, OpenAL...

With those components its possible to write iPhone Java code.

Why would anyone do this except for demostration/academic purposes? No
offense just wondering ... It's not legal and you risk law suits or
other inconveniences. Also when looking at the high adaption rate the
current iPone SDK has I do not see Apple opening to Java anytime soon -
why would they, there are mirads of developers happy to program their
stuff in Objective-C, must use their macs to do so, and in this way
specialize for one specific device which apple wants to sell.

Do not see any reason why Apple would allow Java soon on their phones.

I'm interested for other opinions.

About this, I read news months ago that Sun was developing a JVM for iPhone. The news is 1 year old now (cf http://www.infoworld.com/article/08/03/07/sun-iphone-java_1.html).

Any news about it, anyone ? LWUIT team (you are be directly concerned by this !) ?

Yer I read about that as well before but I really think this will not happen. Ben is right. I do think apple will not allow java on their phones.
