FileNotFoundException

[Woren]

Hello, I got exception after few seconds of running python script on Windows 10 using Cygwin (bsdiff and python installed). Maybe there is some hardcoded path which is not working on Windows / Cygwin? Cygwin is run under "Adminstrator" privileges.

python apk_patch_size_estimator.py --old-file old.apk --new-file new.apk

Exception in thread "main" java.io.FileNotFoundException: \tmp\patch.tmp.filebyfile (System can't find path)

Thank you @Woren for reporting this issue, I will check it out soon.

I recommend using WSL on Windows rather than cygwin/msys. I had issues in the latter environments as well but everything is running great in a WSL Ubuntu installation
