I don't usually use it (because I mostly use the desktop version which has more features such assets, voting, etc) but yes, I have walletnxt by zhang (v1.1.1) installed in my Android device and I was able to create a new account an import an existing one. There is a modifiied "compatible" version of walletnxt also available at Google's Play Store. As far as I know, it was
opensource up to v1.10.5
Anyway, I wouldn't spend a lot of time trying to run walletnxt. Zhang has already announced that this wallet will be discontinued by the end of the year...
Zhang is now focused on Hebewallet, which is compatible with Nxt, is available at the Play Store and works pretty much the same way as walletnxt. Unfortunately, I don't think it's open source (or I haven't found it)
And yes, I agree that it would be good for adoption to have the official Android apps listed on the Play Store. None of them are at the moment. The Ardor Lite wallet that you can find there is a 3rd party wallet developed by mrv777, not the official one.
It's working from here...
