neb.android's Introduction

官方安卓星云钱包（nasnano）接入文档

(测试中，如有问题或建议请及时反馈)

nasnano下载地址：https://nano.nebulas.io/index_cn.html

安卓版本接入简述

在你的项目工程中引入该项目，下面的方式仅为示例（其他包依赖管理方式均可）：

Build libnebulas目录下，libnebulas-release.aar

（1）将aar包复制到你项目的libs中

（2）在build.gradle中引入相关依赖描述

repositories {
    flatDir {
        dir 'libs'
    }
}

dependencies {
...
+    compile(name: 'libnebulas-release', ext: 'aar')
+    implementation 'com.squareup.okhttp3:okhttp:3.10.0'
+    implementation 'com.google.code.gson:gson:2.8.4'
...
}

调用接口

调用接口 pay

public static void pay(Context context,int mainNet, GoodsModel goods, String to, String value, String serialNumber)

        clickButton.setOnClickListener( new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub

                GoodsModel gm = new GoodsModel();
                gm.name = "mytestGood";       // 商品名称
                gm.desc = "mytestGoodDesp";   //商品描述
                String toAddr = "n1lxxx…………………………";  // 目标地址
                String valueInWei = "your value";    // your value
                
                String serialNumber = Util.getRandomCode(32);
                
                SmartContracts.pay(MainActivity.this ,Constants.MAIN_NET, gm, toAddr, valueInWei, serialNumber);

            }
        });

调用接口 call() 传入参数参考上面:

public static void call(Context context, int mainNet, GoodsModel goods, String to, String value, String[] args, String serialNumber)

调用接口 queryTransferStatus() :

queryTransferStatus(int mainNet, String serialNumber, final SmartContracts.TransferStatusCallback callback)

neb.android's Issues

关于调用合约流程的问题

在我开发的App中通过唤起nasnano 钱包并完成智能合约的调用后，页面停留在了钱包页面。比较正常的流程应该是finish 掉钱包页面回到第三方App，同时通过onActivityResult 将用户是否完成了调用的行为通知给第三方App。

execute_result 没有数据

queryTransferStatus 查询的 execute_result 返回的数据为""？请问下怎么回事

What's behaviour of the sdk if user didn't install the NAS Nano wallet?

Are users redirected to the app store / google play if they don't have the Nano wallet, or how does it work in this case?

I was discussing this on slack and no one knew current behaviour yet, but if this is not the current behaviour it would be great to implement this redirection.

Do you plan to add neb.api.call() for reading status in the smart contract in android sdk?

i need to read message saving in the smart contract's localstorage.
if you don't have plan on your road map, i need to do it myself

用最新版的android studio以及用自带的gradle，添加nebulasio android sdk依赖后报以下错误

Configuration 'compile' is obsolete and has been replaced with 'implementation' and 'api'.

Constants.TEST_NET问题

调用pay接口的时候，我写的是Constants.TEST_NET测试网络，但是唤起的钱包里的环境还是主网呀？？？？

SSL errors on android 4.4.2

javax.net.ssl.sslprotocolexception handshake aborted...

See picture for full error message.

Could be something similar to this?: https://stackoverflow.com/questions/29916962/javax-net-ssl-sslhandshakeexception-javax-net-ssl-sslprotocolexception-ssl-han

执行如下方法在部分手机上会跳转到指定的市场，但是你们没有在市场里上架这个app，导致用户根本无法下载，不知道去哪里下载，是否可以直接跳到浏览器里下载呢？我改了下，但是去官方找到的下载地址是跟版本号关联了，希望改正下谢谢
private static void handleException(Context context) {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse(String.format("market://details?id=%s", Constants.NAS_NANO_PACKAGE_NAME)));
if (intent.resolveActivity(context.getPackageManager()) != null) {
Toast.makeText(context, "没安装Nebulas智能数字钱包，请下载安装", Toast.LENGTH_SHORT).show();
context.startActivity(intent);
} else {
intent.setData(Uri.parse(String.format("https://play.google.com/store/apps/details?id=%s", Constants.NAS_NANO_PACKAGE_NAME)));
if (intent.resolveActivity(context.getPackageManager()) != null) {
context.startActivity(intent);
} else {
Toast.makeText(context, "没安装应用市场或浏览器", Toast.LENGTH_SHORT).show();
}
}
}

 SmartContracts.queryTransferStatus(1, "a679e58dc37b6e43cd56ac755dd10d8e1a7382fbcea285805d4a4b708fb38a77",
                        new SmartContracts.TransferStatusCallback() {
                            @Override
                            public void onSuccess(String response) {
                                Log.d(TAG, response);
                            }

                            @Override
                            public void onFail(String error) {
                                Log.e(TAG, error);
                            }
                        });

it returns :

com.tk.nebulas D/MainActivity: {"code":1,"data":{},"msg":"payId a679e58dc37b6e43cd56ac755dd10d8e1a7382fbcea285805d4a4b708fb38a77 does not exist"}

but :
