MEET.ONE SDK Usage

1.Request EOS Authorization

Code Samples

Authorize authorize = new Authorize();
authorize.setDescription("get account info ");

AppInfo appInfo = new AppInfo();
appInfo.setName("app name");
appInfo.setIcon("app icon");
appInfo.setDappCallbackScheme("http");
appInfo.setDappRedirectURL("https://meet.one");
appInfo.setDescription("this is a demo");
appInfo.setVersion("app version");
appInfo.setUuID("")
MeetOneManager.getInstance().requestAuthorize(this,authorize,appInfo, new MeetOneCallBack() {
    @Override
    public void callBack(Map<String, String> paramMap, CallBack callBack) {
        Log.d("MeetOneManager",paramMap.toString()+"  "+callBack.getData());
    }
});

2.EOS Transfer

Code Samples

AppInfo appInfo = new AppInfo();
appInfo.setName("app name");
appInfo.setIcon("app icon");
appInfo.setDappCallbackScheme("http");
appInfo.setDappRedirectURL("https://meet.one");
appInfo.setDescription("this is a demo");
appInfo.setVersion("app version");

Transfer transfer = new Transfer();
transfer.setAmount("0.0001");
transfer.setDescription("i like");
transfer.setFrom("aaaa");//from account name
transfer.setTo("bbbb");//to account name
transfer.setTokenName("EOS");
transfer.setTokenContract("eosio.token");
transfer.setTokenPrecision(4);//set token Precision
transfer.setMemo("aaaa transfers 12.0 EOS to bbbbb");

MeetOneManager.getInstance().requestTransfer(this, transfer, appInfo, new MeetOneCallBack() {
    @Override
    public void callBack(Map<String, String> paramMap, CallBack callBack) {
        Log.d("MeetOneManager", paramMap.toString() + "  " + callBack.getData());
    }
});

3.Push EOS Transactions

Code Samples

AppInfo appInfo = new AppInfo();
appInfo.setName("app name");
appInfo.setIcon("app icon");
appInfo.setDappCallbackScheme("http");
appInfo.setDappRedirectURL("https://meet.one");
appInfo.setDescription("this is a demo");
appInfo.setVersion("app version");


Transaction transaction = new Transaction();
transaction.setDescription("test demo");
String action1 = "{\"account\":\"eosio.token\",\"name\":\"transfer\",\"authorization\":[{\"actor\":\"aaaa\", \"permission\":\"owner\"}],\"data\":{\"from\":\"aaaa\", \"to\":\"bbbb\",\"quantity\":\"0.0001 EOS\",\"memo\":\"test\"}}";
List<String> actions = new ArrayList<>();
actions.add(action1);
transaction.setFrom("aaaa");//from account name
transaction.setActions(actions);
String options = "{\"broadcast\":true}}";
transaction.setOptions(options);
MeetOneManager.getInstance().requestTransaction(this, transaction, appInfo, new MeetOneCallBack() {
    @Override
    public void callBack(Map<String, String> paramMap, CallBack callBack) {
        Log.d("MeetOneManager", paramMap.toString() + "  " + callBack.getData());
    }
});

4.Request EOS Custom Signature

Code Samples

AppInfo appInfo = new AppInfo();
appInfo.setName("moreone");
appInfo.setIcon("app icon");
appInfo.setDappCallbackScheme("moreone");
appInfo.setDappRedirectURL("https://meet.one");
appInfo.setDescription("this is a demo");
appInfo.setVersion("2.4.0");

Signature signature = new Signature();
signature.setAccountName("aaaaa");//provider account name
signature.setData("moreone");//custom signature string
signature.setDescription("this is a demo");//request reason
MeetOneManager.getInstance().requestSignature(this, signature, appInfo, new MeetOneCallBack() {
    @Override
    public void callBack(Map<String, String> paramMap, CallBack callBack) {
        Log.d("MeetOneManager", paramMap.toString());
        mViewBinding.tvContent.setText(paramMap.toString());
    }
});

SimpleWallet SDK Usage

1.Request EOS Authorization

Code Samples

SimpleWalletLogin login = new SimpleWalletLogin();
login.setDappName("more one app");
login.setDappIcon("more one icon");
login.setUuID("xxxx");//uuid
login.setLoginUrl("https://demo/api/login");
login.setLoginMemo("login Memo");
login.setCallback("moreone://login?action=login");
MeetOneManager.getInstance().requestLogin(this, login, new SimpleWalletCallBack() {
    @Override
    public void callBack(Map<String, String> paramMap, String callBack) {
        Log.d("MeetOneManager", paramMap.toString());
        mViewBinding.tvContent.setText(paramMap.toString());
    }
});

2.EOS Transfer

Code Samples

SimpleWalletPay pay = new SimpleWalletPay();
pay.setDappName("more one app");
pay.setDappIcon("more one icon");
pay.setFrom("aaaaaa");
pay.setTo("bbbbb");
pay.setAmount("0.0001");
pay.setSymbol("EOS");
pay.setPrecision(4);
pay.setContract("eosio.token");
pay.setDesc("i am test");
pay.setCallback("moreone://login?action=login");
MeetOneManager.getInstance().requestPay(this, pay, new SimpleWalletCallBack() {
    @Override
    public void callBack(Map<String, String> paramMap, String callBack) {
        Log.d("MeetOneManager", paramMap.toString());
        mViewBinding.tvContent.setText(paramMap.toString());
    }
});
