More feedback after much more testing. I try to rank the issues according to how annoying they are (High: very annoying, Low: I almost don't care). I tested on a Samsung Galaxy S2.
File browser:
F1) There should be an option to set a default file folder to start browsing to. The file system root is confusing because there are so many folders for all the apps installed on the phone. Furthermore people with extensive sgf collections (like me) put them into some folder (maybe shared among different apps) and it's a waste of time having to look for it every time. [Medium]
F2) The back key should go up one directory level and not all the way long to the file system root. [High]
F3) Rotating the phone sends back to the root directory, as the back key does. [High]
F4) The file browser should start from the last accessed folder: Go Tools, Game Records, browse to /a/folder/with/sgf/files, open a file, view it, go back to menu, Game Records, it starts again from root but it should start from /a/folder/with/sgf/files
Recording games:
R1) The setup screen doesn't ask for Rules (chinese/japanese, etc), event, round [Low]
R2) The back key completes the setup and moves on to the goban. This is really unintuitive. Going to the goban is moving forward into the process of recording a game. There should be a Next (or Start or Record) button. The back key should take the user back to the main menu [Low, because I eventually learned it, but it could be a reason to uninstall the app for people that don't learn it]
R3) Tap to insert black 1, white 2, black 3, white 4, tap the < button to undo the last move, tap to insert another white 4 stone. This is ok. Tap < again, tap > (you get the new white 4 stone), tap > again. You should get nothing but you get the old white 4 stone with a 6 label on it. This is wrong. [High]
R4) The editor doesn't understand kos (even the simplest one) and let's take kos immediately [Low]
R5) The back key quits the games and sends back to the menu without asking for confirmation. [High]
Viewing games
V1) Tapping the goban inserts a move. It should do nothing or create a variation. Unfortunately it seems that variations are not supported and furthermore it messes the game record because of R3 [High]
V2) R5 happens also while viewing games.
Playing games (I played from level 5 of 9x9 until I unlocked 13x13 and 19x19):
P1) I played a few games on a slow 3G connection (only one tack) and after a while the AI froze. Maybe it lost the connection. If that's the case it should handle it gracefully, trying to contact the server again and eventually (but let's say within a minute) notifying the player of the problem. I never had problems on WiFi. [Low]
P2) The AI doesn't understand sekis. It counted a seki as if I captured its group (lucky me!). Check the groups on the left in this image. [High]
P3) The AI sometimes keeps playing inside its territory at the end of the game. It would be only a loss of time if we were playing by Chinese rules but we're probably not and, more important, it will confuse inexperienced players who themselves have problems assessing the need to reinforce their own territories. [High]
P4) There should be a way to check rules and komi while playing. [Less than Low]
By the way, do you have a publicly available issue management tool? I rather enter these issues in a trackable format there than in free form here?
This other image shows the problem I had with long file names. I wrote about it in the previous post.
Also check the Location at the top. It is /mnt/sdcard/gobandroid/sgf/ That's what I'd like to use as the default root of the file browser.
I'm sure that this looks like a long list of issues but actually most of the program works well so this already looks like a beta version and not a development one. There are only some UI details to iron out. Maybe the only big issue related to the game is the way the editor gets confused by moving back and forth in the moves sequence and adding new stones.
