导入云平台jar包

1.将jar包放入libs文件夹
路径如图：

implementation files('libs\\nlecloudII.jar')

先开网络权限

在AndroidManifest.xml里加一句

<uses-permission android:name="android.permission.INTERNET" />

数据获取界面类

public class MonitoringActivity extends AppCompatActivity {
    NetWorkBusiness netWorkBusiness;
    String baseUrl = "http://api.nlecloud.com:80/";
    Handler handler = new Handler();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_monitoring);
        initNle();
    }

    private void initNle() {
        netWorkBusiness = new NetWorkBusiness("", baseUrl);
        netWorkBusiness.signIn(new SignIn("你的账号", "你的密码"), new NCallBack<BaseResponseEntity<User>>(this) {
            @Override
            protected void onResponse(BaseResponseEntity<User> response) {
                if (response.getStatus() == 0) {
                    String token = response.getResultObj().getAccessToken();
                    Log.e("token", token);
                    netWorkBusiness = new NetWorkBusiness(token, baseUrl);
                    startDataFetching();
                } else {
                    Log.e("Login Failed", response.getMsg());
                }
            }
        });
    }

    private void startDataFetching() {
        handler.post(runnable);
    }

    Runnable runnable = new Runnable() {
        @Override
        public void run() {
            handler.postDelayed(this, 3000);
            // 获取温度传感器数据
            netWorkBusiness.getSensor("你的设备id", "tem", new NCallBack<BaseResponseEntity<SensorInfo>>(MonitoringActivity.this) {
                @Override
                protected void onResponse(BaseResponseEntity<SensorInfo> response) {
                    if (response != null && response.getStatus() == 0) {
                        String tem = response.getResultObj().getValue();
                        Log.e("tem", tem);
                    } else {
                        Log.e("API Error", response != null ? response.getMsg() : "未知错误");
                    }
                }
            });
        }
    };
}

添加可信CA

在xml里创建network_security_config.xml文件并写入以下内容

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">api.nlecloud.com</domain>
    </domain-config>
    <base-config cleartextTrafficPermitted="true" />
</network-security-config>

在AndroidManifest.xml加入android:networkSecurityConfig="@xml/network_security_config"即可

愉快的使用
