My app won't compile now because a referenced library is missing. I think it is "Dialogs (version 2.20)" which used to be just under Core (v 2.26) in b4a 2.30 under the Lib tab in the ide. Is there one that took its place in v2.50?
Solved the problem. I copied the files from another computer. I believe one of the b4a gurus had written the library I needed. That's why it wasn't part of the core. Also included Reflections lib.
