With ghci, the consol haskell shell is meant, correct?
Yes. (Actually, I think they got ghci working at some point, so this may not be relevant.) Also stuff like the hint and mueval libraries rely on the bytecode interpreter/"ghci".
I do not think I would need ghci on android, for what?
I think I can live without template haskell.
You can for a while, but you might be surprised what libraries use TH behind the covers.
