lib4j dependency on android

[Imran Akbar]

Hi guys,

    I'm using the squirrel state machine on Android, but it keeps crashing with this error:

java.lang.VerifyError: org/apache/log4j/config/PropertySetter

            at org.apache.log4j.PropertyConfigurator.parseAppender(PropertyConfigurator.java:772)

i can see that maven has already downloaded the following to my project:

log4j-1.2.16

slf4j-api-1.6.1

slf4j-log4j12-1.6.1

do i need to switch to using https://code.google.com/p/android-logging-log4j/ or https://code.google.com/p/log4j-android/?

thanks,

I haven't create an android example yet, but it seems android-logging-log4j was used to solved this issue in many cases.[1][2]

thanks He,

  Unfortunately I can't get the android-logging-log4j to work either.  I'm going to try using squirrel as a library project and just remove all references to logging.

Even worse, Android doesn't support any of these imports from /fsm/jmx:

import java.lang.management.ManagementFactory;

import javax.management.MBeanServer;

import javax.management.MalformedObjectNameException;

import javax.management.ObjectName;

Guess I'll just have to write my own FSM or use another library

thanks,

Thanks for your feedbacks. I didn't realize jmx was not available on android devices. However, jmx was newly implemeneted feature, still not released. I guess you may try the latest released version(0.3.2) which does not include jmx support. I will think about android device support later.
