Custom complications for SW 4

Have a good day. I’m a android developer and few year ago published application to Play Store for air quality monitoring. The important part of this application is a complication.

I bought a new SW 4 and installed this app. However complication doesn’t appeared in customizing face screen. Does development on complication is required any specific SDK or etc?

I changed a face to different one and it works fine. Probably “Analog dashboard” doesn’t support it. Cheers.
