manually use `aapt singleCrunch` for reproducible builds PNG crunching is not a deterministic process, especially the way aapt does it. This makes the F-Droid builds not reproducible. The easy solution to this is to pre-crunch the PNGs and commit them to git. It also makes the final APK a tiny amount smaller, for whatever reason. https://medium.com/@duhroach/smaller-pngs-and-android-s-aapt-tool-4ce38a24019d 2017-09-02 23:01:09 +02:00			`#!/usr/bin/env sh`
