[ecdsa]

did you run 'make theming'?
that is in the android Readme, but it is actually needed for desktop too
maybe we should print it at runtime

[brianddk]

did you run 'make theming'?

@ecdsa , Thx, I had thought I scrubbed the android FAQ, but I obviously missed that. Thanks for pointing it outl.

maybe we should print it at runtime

Well it wil it will show up on an issue search if anyone misses it in the future
