I've built a cryptocurrency of my own using this video guide. I did the first 4 steps out of 6, as the 5th level is about building a wallet for Windows platform.
I have started creating this cryptocurrency so it would be able to trade using it only on mobile devices running Android and iOS. Right now I would like to start to develop it for Android platform.
My question is how can I create a wallet for Android using Java that will support my self-made cryptocurrency? By wallet I mean to store the coins, send and receive them, and ability to open new wallets.
