As of VICE 3.2 all UIs except GTK3 and SDL have been removed from the main line of VICE to make maintenance easier. The SDL port will keep working on Android, but it is a very barebones solution. However, there are third party ports to Android, which are listed here:
Appears to be the SDL port of VICE with some android stuff on top (but its different to "our" UI). This port is free.
Developer: Gerhard Stein
VICE version: 2.4 (?) (last updated August 6, 2017) (checked 2018-05-14)
The SDL port of VICE with some android stuff on top. The developer asks 2,49 euros for it.
This port (AnVICE 1.0.5) was merged into the VICE main tree in january 2013 and became the "official" android port after that.
VICE version: 2.3 (last updated April 6, 2012) (checked 2018-05-14)
This is a fully native port that does not use SDL. The developer asks 3,49 euros.
This seems to be the best working port, and is the one recommended to use. Occasionally you can find free downloads of beta versions on the website of the developer.
Developer: Robert Broglia
