Great everyone, thank you. So now the repository is https://github.com/riecointeam/riecoin , and the https://github.com/clo-prime/riecoin-0.16 one is dropped?

lzknr, one possibility for you could be to look at some thin wallets (like Electrum) and fork one for Riecoin. Indeed, having a Riecoin Core update is nice, but for mainstream adoption, we need something very simple that can be used instantly out of the box (i. e. without having to download the blockchain,...). And sure, an Android wallet is a must have. If you are willing to do so, it will be a very nice contribution for Riecoin.
