一個EOS的Android端實現庫
阿新 • • 發佈：2018-12-13
簡介：
這是一個EOS的Android端實現，本庫可以建立EOS的公私鑰，查詢餘額，交易，投票，EOS的account繫結，離線簽名等，幾乎所有EOS的操作。

歡迎star
support Android sdk >= 14
- 如何使用
- 先新增bip44forandroidlibrary的依賴
implementation ‘party.loveit:bip44forandroidlibrary:1.0.7’
- 生成 EOS相關的公鑰私鑰
code:
List<String> words = Bip44Utils.generateMnemonicWords(MainActivity.this);
Log.e("TAG", "words: " + words.toString());
BigInteger pri = Bip44Utils.getPathPrivateKey(words,"m/44'/194'/0'/0/0");
Log. result:
2018-12-06 14:41:26.636 976-1101/? E/TAG: words: [cluster, page, museum, protect, bronze, leg, few, guide, sport, resource, luxury, magnet]
