Hi, didn't think that would work because it is not on PyPi but rather on github.
Just tried and it didn't work:
Collecting plyer==1.3.1dev (from -r requirements.txt (line 1))
Could not find a version that satisfies the requirement plyer==1.3.1dev (from
-r requirements.txt (line 1)) (from versions: 1.1, 1.1.1, 1.1.2, 1.2.0, 1.2.1,
1.2.2, 1.2.3, 1.2.4, 1.3.0)
No matching distribution found for plyer==1.3.1dev (from -r requirements.txt
(line 1))
I believe PyPi has the ability to hold development versions now---perhaps a
future buildozer could take the metadata into account.
Thanks,
