Examples

Chain configuration

    // default config. Mainnet network
    Config config = Config.custom().build();

    // Testnet with using several nodes to connect
    try {
        config = Config.custom()
                .setWebWalletUrl("https://wallet.testnet.mile.global")
                .setUseBalancing(true)
                .fetchApiUrlsFromWebWallet()
                .build();
    } catch (WebWalletCallException e) {
        e.printStackTrace();
    }

    // Testnet with using concrete node
    config = Config.custom()
            .setApiUrls(Arrays.asList("https://lotus000.testnet.mile.global"))
            .build();

    Chain chain = new Chain(config);

Create wallet, check balance

    Wallet wallet = new Wallet(); // new random wallet
    wallet = new Wallet("secret-phrase"); // wallet from secret phrase

    System.out.println(wallet.getPublicKey() + " " + wallet.getPrivateKey());

    try {
        for (Balance balance : wallet.getState(chain).getBalances()) {
            System.out.println(balance);
        }
    } catch (ApiCallException e) {
        System.out.println(e.getMessage());
    }

Transfer tokens

    Wallet destinationWallet = new Wallet("destination-secret-phrase");
    int assetCode = Asset.XDR;  // or Asset.MILE
    wallet.transfer(chain, destinationWallet, assetCode, new BigDecimal("0.01"));

    String destinationAddress = "2PThr9EhKLYJ7renYVogHqFXsLSp1UCAkcotU3HLNCrstJnhvo"; // aka public key
    String description = "test transfer";
    BigDecimal fee = new BigDecimal("0");
    wallet.transfer(chain, destinationAddress, assetCode, new BigDecimal("0.01"), description, fee);

Explore blocks

    BigInteger lastBlock = chain.getCurrentBlockId();

    for (BigInteger i = lastBlock.subtract(new BigInteger("15")); i.compareTo(lastBlock) < 0; i = i.add(new BigInteger("1"))) {
        Block block = chain.getBlock(i);

        System.out.println(block.getId() + " :: " + block.getTimestamp());
        for (Transaction t : block.getTransactions()) {
            System.out.println(t);
        }

    }
