Meh, the only difference between the working app and the failed one was the gradle dependency line. I assume I must be missing something such as a meta value, but without a working sample to start from, I’d just be grasping at straws.
My client’s app needs to be able to work offline, so the web service work work for me. I’d continue to use the spell checker from the framework, but it no longer works on some vendors’ devices.
In any case, thank you for your response.
