   Material Design file manager for Android

   

   Supporting Android 5.0+ is impressive, though there was another file manager supporting Android 1.0+ discussed recently https://news.ycombinator.com/item?id=38789958 (I'm impressed by both, not an Android developer, curious how one ensures compatibility with ancient versions; actual testing, a compatibility linter, other?)

   I also enjoy Material Files' README, particularly https://github.com/zhanghai/MaterialFiles#why-material-files (a clear articulation of "Why" is always informative) and https://github.com/zhanghai/MaterialFiles#inclusion-in-custo... (clear guidance to upstreams seems relatively uncommon, helps shed light on ecosystem dynamics otherwise invisible to me anyway).

   A microsite overview of all Android 🤖 versions and their corresponding API/SDK levels, version codes, codenames, and market shares.

   

   I'm not saying _nobody_ uses those devices, I'm just saying they're sufficiently old that saying _my app supports Android 3.x_ is moot, because the usage on that API will be near 0 anyway, so you never really know if you _support_ that version outside of any testing that you might be doing. Android 4 and lower have estimated share of 0.3%-0.7% depending on a source ([1], [2]). Of course HN users will be more likely to have those devices too. And then of 0.5% users that maybe will install the app some will have no issues, some will have issues but not notice, some will notice but not bother reporting.
