Workflow ID not found Android SDK exception

[mcasanket]

Hi All,

When I try to start workflow it gives the exception.

When I debugged the exception is thrown from the below line
       

            WorkflowService workflowService = this.session.getServiceRegistry().getWorkflowService();

            // Tried both the belwo lines one by one
            String processDefinitionIdentifier = WorkflowModel.KEY_REVIEW_ACTIVITI;
            processDefinitionIdentifier = "activiti$activitiReview";

            // Exception thrown from below line 
            ProcessDefinition processDefinition = workflowService.getProcessDefinition(processDefinitionIdentifier);
        ‍‍‍‍‍‍‍‍‍‍

<strong>Exception</strong>:

Aloah,

Depending on your CMIS endpoint during session creation the process definition identifier is a little bit different. Indeed if the public API is used the prefix 'actviti$' is useless.

To summarize,

If your endpoint url is like <AlfrescoServerHostname>:<port>/alfresco/cmisatom
Process Definition Identifiers have 'actviti$' prefix like "activiti$activitiReview"

If your endpoint url is like <AlfrescoServerHostname>:<port>/alfresco/api/-default-/public/cmis/versions/1.0/atom/
Process Definition Identifiers don't have 'actviti$' prefix like "activitiReview"

If your endpoint url is like <AlfrescoServerHostname>:<port>/alfresco
and your Alfresco Server has Public API (4.2Enterprise or 4.2.e+ community If my memory is good)
Process Definition Identifiers don't use the 'actviti$' prefix like "activitiReview"

If your endpoint url is like <AlfrescoServerHostname>:<port>/alfresco
and your Alfresco Server doesn't have Public API
Process Definition Identifiers use the prefix "activiti$" like "activiti$activitiReview"

Thanks for your reply.

When I go to workflow console and fire a command "show definitions all" it shows  me the below result. In that the process id is as below.
id: activiti$activitiReview:1:8 , name: activiti$activitiReview , title: Review And Approve , version: 1

I have attached the screenshot.

I am developing using Alfresco-Android sdk 1.3.1 version.
Alfresco version is 4.2.2.

However the same code was working before with alfresco 4.1 versions…

Please help.

As said previously 4.2 has introduced the public API. It's the official recommended REST API.
The public API has a different URL than other Alfresco REST API.

With Alfresco 4.2 when you create a RepositorySession with an url like http://myhostnameort/alfresco, we will automatically bind to http://myhostnameort/alfresco/api/-default-/public/cmis/versions/1.0/atom/
With Alfresco 4.0.x & 4.1.x when you create a RepositorySession with an url like http://myhostnameort/alfresco, we will automatically bind to http://myhostnameort/alfresco/cmisatom

If you create your RepositorySession with an url like http://myhostnameort/alfresco/cmisatom your code should works as previously.
But if you want to use the public API on 4.2, you need to rework your processDefinition and remove the activiti$ prefix which is useless.
Another approach is to use the session.getServiceRegistry().getWorkflowService().getProcessDefinitions() to list all process definition, find your requested definition by its name and then use it.

Hope it helps.
