Thanks for the reply! Turns out, that Kaspersky is scanning aapt on each access. That makes it around 60k file operations on the same aapt file. I guess I'll need to talk to the responsible guys for an exemption...
Re calling aapt for every file: Couldn't you reduce the number of calls by spawning multiple aapt processes and let each process work on a pack of files? I don't know what the command limit is, but that could be determined on runtime I guess. Or divide the files to be worked on in an arbitrary amount of temp directories and let aapt run on directories instead of single files again. At least for the inital task run. As you noted, consecutive task runs are much faster. Anyway, thanks for the support! Am Dienstag, 25.
