[区块链]Android Java 创建与导入BTC钱包、BTC普通地址与隔离地址转换

引入最新版本bitcoinj包

    api 'org.bitcoinj:bitcoinj-core:0.16.1'
    api 'org.slf4j:slf4j-api:1.7.32'

1、根据助记词创建btc钱包

   val BITCOINJ_NETWORK_PARAMETERS: NetworkParameters =
        if (BuildConfig.DEBUG) TestNet3Params.get() else MainNetParams.get()

    public static ImmutableList<ChildNumber> generatePath(String path) {
        List<ChildNumber> list = new ArrayList<>();
        for (String p : path.split("/")) {
            if ("m".equalsIgnoreCase(p) || "".equals(p.trim())) {
                continue;
            } else if (p.charAt(p.length() - 1) == '\'') {
                list.add(new ChildNumber(Integer.parseInt(p.substring(0, p.length() - 1)), true));
            } else {
                list.add(new ChildNumber(Integer.parseInt(p), false));
            }
        }
