How can I configure Rodent IV in Android chess GUIs?

[tapio]

Seems to work under DroidFish.

Works, including personality books. But the other distribution has the nn-62ef826d1a6d.nnue - where to put it... there is no hint if it's being used, it's not configurable in the uci options.

There is nothing to consider. The network is already embedded. Are you sure it works? I was a little in doubt.

Well, at least according to the UCI options. And it uses the player books afaics (eg, chose a nimzo opening. And instant book move). Book use on DroidFish side is off.

I just don't know why there's 2 personalities to pick.

I have not seen this with the personality files supplied for Rodent NNUE. But it does with the personality files from Rodent IV. So it also works for Rodent NNUE. I would be happy to create an APK file here too, if desired.

apk is interesting, if it would work fully in e. g. Acid Ape Chess. But I think there Rodent will not see the Rodent4 folder. And not make use of personality books. Your non-nnue Rodent 4 distrib imo does not fully work in Acid Ape.

This is probably due to the new Google Play guidelines (no access to files outside the app). Grant storage access permission to a chess app no longer works (exceptions: Chess for Android 6.2.1 and DroidFish).

The additional files (books and personality files) would have to be embedded in the executable file, similar to what is done with the networks. Then it would work. Alternatively, you would have to copy the additional files into the private directory of the chess app. Each chess app has its own private directory to which it can read and write. For Chess for Android, for example, the private directory is /storage/emulated/0/Android/data/com.google.android.chess. If you copy the additional files (books and personality files) into this directory (/storage/emulated/0/Android/data/com.google.android.chess/Rodent4), it will also work with the latest version of Chess for Android. However, you have to adapt the source code of Rodent accordingly so that Rodent knows where to find its additional files.

The following version should work for Acid Ape Chess. Simply copy the additional files into the following directory:
/storage/emulated/0/Android/data/com.acideapestudios.acidapechess/Rodent4/
If you cannot create the directory, then use a connected computer.

Oh great, thx for your effort. No, it's not working, I assume it because it does not make of personality books. I copied Rodents files to where you wrote, so eg there is /storage/emulated/0/Android/data/com.acideapestudios.acidapechess/Rodent4/personalities/

Acid Ape on my Android 10 has its files in some hidden place, for non-root. It did not use
Android/data/com.acideapestudios.acidapechess/Rodent4

E. g., I cannot access its pgn of played games via Totalcmd. I don't know where it's user files reside. Maybe /data/data/... thx Google.

Where does the apk installer put your engine files?

I use the chess engine support library for Android from https://github.com/gkalab/chessenginesupport-androidlib and adapted the project to the latest version of Android Studio. I haven't explicitly looked into this yet, but presumably the apps are installed to /data/app.

I'll test the whole thing myself. However, I had to realize that Acid Ape Chess does not work for me. When I start it, I get a strange message that a license could not be found, but Acid Ape Chess is free, right? I'll test it on another device.

We're already talking about this version here?
