Note: This is not a standalone app. In Gobandroid ( https://f-droid.org/packages/org.ligi.gobandroid_hd/ ) press Setup -> GNU Go to activate it. This is a plugin that enables the GNU Go 3.8 engine to play as an AI player inside Gobandroid. After install please restart Gobandroid so it is detected. The app does not have a launcher icon so it can be uninstalled either from F-Droid Client or from Android Settings Apps.
