JBox2D 2.1.2 Expection (new world creation)

Question

I try to create an application for mobile phone LG GT-540 (Android 2.1). The application does not work if I initialize the new world
... world = new World(gravity, doSleep);

Will be grateful for any ideas how to overcome this problem...

Answer 1

I met the same problem as this exception

Caused by: java.lang.NoClassDefFoundError: org.slf4j.impl.StaticLoggerBinder
    at org.slf4j.LoggerFactory.bind(LoggerFactory.java:121)
    at org.slf4j.LoggerFactory.performInitialization(LoggerFactory.java:111)

it told I don't include the slf4j dependency，but jbox2d-library-2.1.2.jar has already include slfj4, so you could change the "slf4j" package inside the jbox2d.jar to the most recent version,it would fix this error.

and this jbox2d issue refers here, you could find the most recent version of slf4j in that page.
