- Use it

1. first add Bip44ForJava dependencies

implementation 'party.52it:Bip44ForJava:1.0.0'

2. generate EOS

code:

                    List<String> words = Bip44Utils.generateMnemonicWords();
                    Log.e("TAG", "words: " + words.toString());


                    BigInteger pri = Bip44Utils.getPathPrivateKey(words,"m/44'/194'/0'/0/0");
                    Log.e("TAG", "pri1: " + pri.toString(16));

                    String eospk =  Ecc.seedPrivate(pri);
                    Log.e("TAG", "EOS privateKey: " + eospk);

                    String eospuk =  Ecc.privateToPublic(eospk);
                    Log.e("TAG", "EOS publicKey: " + eospuk);
 

result:
