> OS : Ubunutu 22.04 Processing Android works fine, but I’m annoyed by a small problem : each time I re-open it, Processing asks me to download the SDK again, or to locate it. Both works, but why is that happening ? Can’t processing store the link to the SDK, or can’t the OS know it by itself ? I read a few posts dealing with this issue and some say that the workaroud is to install the whole android studio. It seems a little extreme ! [image]
