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);
}
}
