Cross platform Etheroll app built with Python and Kivy.
Uses an Ethereum smart contract to place bets on the blockchain.
Note the introduction of `srclibs/buildozer.txt` to use the
non-mainstream `buildozer` wrapper.
The build relies on buildozer master (post 0.39 release) which fixes
issues with unsigned releases.
Cython is pinned since this is the official tested version with
buildozer.
Both SDK and NDK path are set to use fdroid ones.
The auto accept license is disabled since fdroid sdkmanager doesn't
support the --licenses argument.
