// String chain = JingtumWallet.BIZAIN_CHAIN;

mJingtumWallet.createWallet(chain, new JCallback() {
    @Override
    public void completion(JCCJson jccJson) {
        String secret = jccJson.getString("secret");

        // the secret and address is not null if create wallet successfully
    }
});

importSecret

String secret = "";

String chain = JingtumWallet.SWTC_CHAIN;
// String chain = JingtumWallet.BIZAIN_CHAIN;

mJingtumWallet.importSecret(secret, chain, new JCallback() {
    @Override
    public void completion(JCCJson jccJson) {
        String secret = jccJson.getString("secret");
        String address = jccJson.getString("address");
        // the secret and address is not null if import secret successfully
    }
});

isValidAddress

String address = "";

String chain = JingtumWallet.SWTC_CHAIN;
// String chain = JingtumWallet.BIZAIN_CHAIN;

mJingtumWallet.isValidAddress(address, chain, new JCallback() {
    @Override
    public void completion(JCCJson jccJson) {
        Boolean isValid = jccJson.getBoolean("isValid");
        // the isValid is true if the address is valid
    }
});

isValidSecret

String secret = "";

String chain = JingtumWallet.SWTC_CHAIN;
// String chain = JingtumWallet.BIZAIN_CHAIN;

mJingtumWallet.isValidSecret(secret, chain, new JCallback() {
    @Override
    public void completion(JCCJson jccJson) {
        Boolean isValid = jccJson.getBoolean("isValid");
        // the isValid is true if the secret is valid
    }
});

sign

JSONObject transaction = null;

String secret = "";

String chain = JingtumWallet.SWTC_CHAIN;
// String chain = JingtumWallet.BIZAIN_CHAIN;

mJingtumWallet.sign(transaction, secret, chain, new JCallback() {
    @Override
    public void completion(JCCJson jccJson) {
        String signature = jccJson.getString("signature");
        // the signature is not null if sign successfully
