Answer 1

Actully the question is "How get the running activity instances". And I already got the answer from somewhere.

Here is the aswer.

Just use the java api like below

ActivityInstance activityInstance = runtimeService.getActivityInstance(instance.getProcessInstanceId());
ActivityInstance[] activityInstances = activityInstance.getChildActivityInstances();

The activityInstances array is the running activity instances. you can use the ids of the activity instances to cancel running activity instance.

Had the same trouble. This line returns a list of ids (whatever they are - user task, service task, and etc). If you don't have parallel active tasks - the list will contain a single activity id.

    processEngine.getRuntimeService().getActiveActivityIds(
        processInstance.getProcessInstanceId()
    );
