new Process Access Denied
Hi,
I have been trying to run the chess engine binary stockfish from Android (stockfish-10-armv7). For PC in editor and .exe it works fine but I have an access denied error when I try to run it through new Process() on Android.
The binary is in the steamingAssets and at run time i can find it using unitywebrequest and write it into the Application.persistentDataPath. I have checked to see if i have the write /read privilege for external storage.
Anyone have any ideas?
