After I updated Visualizer to 8.2.1, synchronous services started to give "Unhandled exception: param is not defined" error. Same services work with 8.1.15. Also Visualizer app fails to launch the app for the second time after I receive the "param is not defined" error. When I launch the app from Visualizer for the second time it fires invalidServicename error. I can only continue working if I delete the Visualizer app data and cache from the Android device.

I wonder if the update had problems or it is a generic problem for 8.2.1?

Hi,

You can achieve the requirement of calling the service synchronously by invoking the service in an asynchronous manner (here I assume you are using the Viz actions for invocation) and then writing code to block the UI till you get a response on the service.

Hope this resolves your query.

Thanks,
