Note: osu!droid is NOT the same as osu! (it's made by two different entities), so you can't expect that your osu! account works with this one as well (nor does score, support or anything like that).
So try to refrain from bothering the osu! team about osu!droid related questions and Problems as they most likely won't have any answer for it. (This includes writing about it in the wrong forums section, see below)
