Dogecoin Wallet for Android lets you keep Dogecoins right with you on your phone. It is a port of the Bitcoin Wallet for Android by @schildbach.
The app is based on DogecoinJ, which in turn is a port of BitCoinJ (@bitcoinj). You can find DogecoinJ here: https://github.com/langerhans/dogecoinj-new I ported all the needed changes for Dogecoin compatibility over.
You can get the app directly from the Google Play store: https://play.google.com/store/apps/details?id=de.langerhans.wallet
Alternatively you can download the current version for sideloading right here on this page.
Please contact me before you want to contribute.
Basicially you clone both this repo and DogecoinJ and compile it with Maven. More info is included in the README file.
