This port is based on work done by Kashif Dar et al., who kindly shared the source code of their port of Activiti 5.13. This project is heavily based on the work done by them. This is a very experimental project, several modules have been removed or modified, so do not expect all of Activitis features to work.
- Activiti Engine
- Activiti Model
- Activiti Converter
The following modules have been adapted:
- XML Parsing: instead of XMLStreamReader and XMLStreamWriter from javax.xml.stream, using XmlPullParser and XmlSerializer from org.xmlpull.v1.
- Java Beans: using com.googlecode.openbeans instead of java.beans
- SQLDroid SQLDroid used for persistence
- and more
The following classes that belong to the Activiti software have been entirely commented out:
- BusinessRuleTaskActivityBehavior.java
- BusinessRuleParseHandler.java
- RulesAgendaFilter.java
- RulesDeployer.java
- RulesHelper.java
- ProcessDiagramCanvas.java
- ProcessDiagramGenerator.java
- ProcessDiagramLayoutFactory.java
- ScriptExecutionListener.java
- ScriptTaskListener.java
- JtaTransactionContext.java
- JtaTransactionContextFactory.java
- JtaProcessEngineConfiguration.java
- JtaRetryInterceptor.java
- JtaTransactionInterceptor.java
- SpringBeanFactoryProxyMap.java
- BeansConfigurationHelper.java
- DbSchemaCreate.java
- MailActivityBehavior.java
- Bpmn20NamespaceContext.java
Known issues (by no means is this a definitive list):
When querying the DB for process instances, e.g. with:
#!Java
List<ProcessInstance> instanceList = event.getEngineServices().getRuntimeService()
.createProcessInstanceQuery().active().list();
The above code should filter process instances with the state "Active" and return a list of them. The filtering method "active()" causes this code to fail with the message:
#!java
java.lang.ClassNotFoundException: Didn't find class "java.beans.Introspector" on path: DexPathList.......
