I try ‘fuse build --target=Android’ but found not ‘Sockets’ from ‘[Uno.Net](http://Uno.Net)’ Local preview(on PC) is no problem. ‘fuse preview’ This problem is only build android or ios. How can I build? Thanks. ---

Try adding `"Uno.Net.Sockets"` under `"Packages"` in your `.unoproj`. The reason it works in preview is likely that preview pulls in that package for other reasons.
