Android钱包集成

Version 1.0.0

内容:

​

The example below is in Java, android sdk the same with java sdk.

1. 与链交互

1.1 初始化

String ip = "http://polaris1.ont.io"; //test net
String ip = "http://dappnode1.ont.io"; //main net
String rpcUrl = ip + ":" + "20336";
OntSdk ontSdk = OntSdk.getInstance();
ontSdk.setRpc(rpcUrl);
ontSdk.setDefaultConnect(ontSdk.getRpc());

1.2 查询

查询 Unbound ong

通过地址查询余额，ONT, ONG, claimable ONG and unbound ONG.

2. 账号

2.1 助记词和keystore

Users can use the menmonic code to create an account. The BIP44 path Ontology uses is “m/44’/1024’/0’/0/0”.

Mnemonic code


//generate Mnemonic Code
String code = MnemonicCode.generateMnemonicCodesStr();

//get private keyfrom Mnemonic Code
byte[] prikey = MnemonicCode.getPrikeyFromMnemonicCodesStrBip44(code);
System.out.println(Helper.toHexString(prikey));

//create account
com.github.ontio.sdk.wallet.Account acct = ontSdk.getWalletMgr().createAccountFromPriKey("name",prikey,"password");

Keystore is a data structure to backup user’s account.And it can saved in QR code.Then users can use mobile to scan that QR code to read the data and recover the account. You can check the Wallet Specification to see more info.

//get keystore
Scrypt scrypt = new Scrypt();
com.github.ontio.sdk.wallet.Account account = OntSdk.getInstance().getWalletMgr().getWallet().getAccount("address");
//TODO change scrypt and account value

//export keystore
Map keystore = WalletQR.exportAccountQRCode(scrypt,account);
System.out.println(JSON.toJSONString(keystore));

//import keystore
String prikey2 = WalletQR.getPriKeyFromQrCode(JSON.toJSONString(keystore),"password");

//
Account acct2 = new Account(prikey2,SignatureScheme.SHA256WITHECDSA);

import keystore

 
String prikey2 = WalletQR.getPriKeyFromQrCode(JSON.toJSONString(keystore),"password");

2.2 随机创建账号

com.github.ontio.sdk.wallet.Account acct = ontSdk.getWalletMgr().createAccount("name","password");
ontSdk.getWalletMgr().writeWallet();

remove account from wallet:


ontSdk.getWalletMgr().getWallet().removeAccount("")
ontSdk.getWalletMgr().writeWallet();

2.3 通过私钥创建账号

com.github.ontio.sdk.wallet.Account acct = ontSdk.getWalletMgr().createAccountFromPriKey("name",prikey,"password");
ontSdk.getWalletMgr().writeWallet();

2.4 通过WIF创建账号


byte[] prikey = com.github.ontio.account.Account.getPrivateKeyFromWIF("");
com.github.ontio.sdk.wallet.Account acct = ontSdk.getWalletMgr().createAccountFromPriKey("name",prikey,"password");
ontSdk.getWalletMgr().writeWallet();

2.5 地址

单签地址和多签地址


String privatekey0 = "c19f16785b8f3543bbaf5e1dbb5d398dfa6c85aaad54fc9d71203ce83e505c07";
String privatekey1 = "49855b16636e70f100cc5f4f42bc20a6535d7414fb8845e7310f8dd065a97221";
String privatekey2 = "1094e90dd7c4fdfd849c14798d725ac351ae0d924b29a279a9ffa77d5737bd96";

//
com.github.ontio.account.Account acct0 = new com.github.ontio.account.Account(Helper.hexToBytes(privatekey0), ontSdk.defaultSignScheme);
Address sender = acct0.getAddressU160();

com.github.ontio.sdk.wallet.Account acct = ontSdk.getWalletMgr().createAccountFromPriKey("name",prikey,"password");
acct.address

//base58 address decode
sender = Address.decodeBase58("AVcv8YBABi9m6vH7faq3t8jWNamDXYytU2")；

multi-signature address：
Address recvAddr = Address.addressFromMultiPubKeys(2, acct1.serializePublicKey(), acct2.serializePublicKey());
方法 参数 描述
addressFromMultiPubkeys int m,byte[]… pubkeys M,pubkey

3. Native 资产

3.1 ONT 转账

example：demo

String hash = ontSdk.nativevm().ont().sendTransfer(acct0,"AUe2KKPnNMnM7hLHj6dEPJ4PA2m4pyJt2d",200,payerAcct,20000,500);

| 方法 | 参数 | 描述 | | :———– | :———————————————————– | :———————————————————– | | sendTransfer | String sendTransfer(Account sendAcct, String recvAddr, long amount, Account payerAcct, long gaslimit, long gasprice) | sendAcct,recvAddr,amount,payer,gaslimit,gasprice |

3.2 ONG 转账

参考例子：例子

ONG 转账：

String hash = ontSdk.nativevm().ong().sendTransfer(acct0,"AUe2KKPnNMnM7hLHj6dEPJ4PA2m4pyJt2d",200,payerAcct,20000,500);

3.3 提取 ONG

  1. 查询 unboundOng
  2. 提取 ONG
query unboundOng:
String addr = acct0.getAddressU160().toBase58();
String ong = sdk.nativevm().ong().unboundOng(addr);

//withdrawOng
com.github.ontio.account.Account account = new com.github.ontio.account.Account(Helper.hexToBytes(privatekey0), ontSdk.signatureScheme);
String hash = sdk.nativevm().ong().withdrawOng(account,toAddr,64000L,payerAcct,30000,500);
函数 参数 描述
withdrawOng String claimer,String to,long amount,String payer,long gaslimit,long gasprice from,to,amount,payer,gaslimit,gasprice

3.4 构造转账

参考例子：例子

转账


Address sender = acct0.getAddressU160();
Address payer = acct1.getAddressU160();
Address recvAddr = acct1;

//Address recvAddr = Address.addressFromMultiPubKeys(2, acct1.serializePublicKey(), acct2.serializePublicKey());


long amount = 1000;
Transaction tx = ontSdk.nativevm().ont().makeTransfer(sender.toBase58(),recvAddr.toBase58(), amount,payer.toBase58(),30000,0);


ontSdk.signTx(tx, new com.github.ontio.account.Account[][]);//sender
ontSdk.addSign(tx,new com.github.ontio.account.Account[][]);//payer

ontSdk.getConnect().sendRawTransaction(tx.toHexString());
函数 参数 描述
makeTransfer String sender，String recvAddr,long amount,String payer,long gaslimit,long gasprice sender,to,amount,payer,gaslimit,gasprice
makeTransfer State[] states,String payer,long gaslimit,long gasprice multi state

签名

如果转出方和网络费付款人不是统一个人，两则都需要签名.

1.add Sign
ontSdk.addSign(tx,acct0);

2.add MultiSign if address is MultiSign address
ontSdk.addMultiSign(tx,2,new com.github.ontio.account.Account[]{acct0,acct1});

一转多多转多

  1. 构造多个state
  2. 签名
Address sender1 = acct0.getAddressU160();
Address sender2 = Address.addressFromMultiPubKeys(2, acct1.serializePublicKey(), acct2.serializePublicKey());
int amount = 10;
int amount2 = 20;

State state = new State(sender1, recvAddr, amount);
State state2 = new State(sender2, recvAddr, amount2);
Transaction tx = ontSdk.nativevm().ont().makeTransfer(new State[]{state1,state2},sender1.toBase58(),30000,0);

//signature：
ontSdk.signTx(tx, new com.github.ontio.account.Account[][]);
ontSdk.addMultiSign(tx,2,new com.github.ontio.account.Account[]{acct1, acct2});

4. 数字身份

4.1 注册

参考例子：例子


Identity identity = ontSdk.getWalletMgr().createIdentity(password);
ontSdk.nativevm().ontId().sendRegister(identity,password,payerAcct,ontSdk.DEFAULT_GAS_LIMIT,0);

4.2 查询身份

参考例子：例子


String ddo2 = ontSdk.nativevm().ontId().sendGetDDO(identity.ontid);

4.3 身份keystore

com.github.ontio.sdk.wallet.Identity identity = OntSdk.getInstance().getWalletMgr().getWallet().getIdentity("ontid");
Map keystore = WalletQR.exportIdentityQRCode(scrypt,identity);
System.out.println(JSON.toJSONString(keystore));

导入助记词

 
String prikey2 = WalletQR.getPriKeyFromQrCode(JSON.toJSONString(keystore),"password");
