What is the most performant 2D graphics engine for use with Android?

I have managed to make a hello world JBox2D application, and it works (I have some bouncing balls). However, I just read a comment on a forum post, which claims that JBox2D produces a lot of garbage, and so causes animation to be poor. Is this true?

If yes, then what other 2D engines are available to me? I would very much like to us开发者_JS百科e a physics engine for my 2D game, even if it's just a very simple one.

Update:

Just tried running the JBox2D bouncing balls demo on my phone, and the performance was terrible. Looks like libgdx is the way to go for physics, since I think it comes with a native version of Box2D that works well on Android. As for AndEngine, this is a game engine and not a physics engine, but I may use it in conjunction with libgdx to give myself a head start.

Update 2:

I've had a quick play with libgdx and AndEngine. I've found that they're both Android game engines, but AndEngine has a less steep learing curve at the cost of being more limiting. So if you want to build a serious game, you probably want to use libgdx as it will allow you to do more (but is harder to use).

JBox2D is a port from the native version called Box2D. The native version obviously didn't need to worry about garbage collection as it was written for a language which used manual memory management (C++ I think).

The problem comes as the port for Java JBox2d hasn't been optimised, and as of such, lots of temporary variables are created which triggers garbage collections a lot and consequently really slows the framerate.

As Cristian suggested, you could try AndEngine. I can't remember if this uses JBox2d though or the native Box2D.

I would personally suggest the engine by BadLogicGames called LibGDX here:

http://code.google.com/p/libgdx/

It definitely uses Box2D natively and has the option of developing your whole application on your desktop and only porting to android occasionally for testing. Porting only needs a few lines of code and there are a couple of example apps so its not too tricky! :)

It is also very well maintained, updates are being made to it all the time!

Anyway, Hope this helps!

Andy.

Have you seen AndEngine? You can take a look at this app: Farm Tower. They used AndEngine to write it, and it uses physics.

Cocos2Dx because of portability, effects and game performance

I'd definitely recommend LibGdx. It includes Box2d indeed, and an easy way to build for desktop which comes in handy for quick testing. Well documented and a great community behind.
