作为应用的重要关注指标-激活, 需要在每次启动时, 都上传手机的物理标识到服务器. 我来简述一下需要上传的信息.

1. 获取

激活信息主要包含:
1. AppId: 公司拥有多款应用, 标示本应用的类型.
2. Platform: 平台Android或者iOS.
3. SystemVersion: 在Android中, 代表Android版本号.
4. Version: 本应用的版本.
5. AppVersion: 本应用的服务器接口版本.
6. IMEI(International Mobile Equipment Identity): 国际移动设备标识, 手机身份.
7. DeviceId: 设备标示, 一般是IMEI, 也可以是Mac地址.
8. Mac: WIFI的Mac地址.
9. SecureId: 设备随机生成的第一个引导, 间接获取设备寿命.
10. InstallId: 应用安装时间.
11. MODEL: 设备型号
12. MANUFACTURER: 设备生产工厂.

其中获取DeviceId需要权限: READ_PHONE_STATE; 获取Mac地址需要权限 ACCESS_WIFI_STATE.

            }
            connection.disconnect();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

为了减少获取代价, 可以存储一些关键值到首选项.

2. 上传

网络请求必须使用异步线程, 我们只是上传激活, 并不关心返回值, 比较简单.

  new PostActiveTask().execute(); // 发送激活信息

      // 发送激活任务的线程
    private class PostActiveTask extends AsyncTask<Void, Void, Void> {
        @Override
        protected Void doInBackground(Void... params) {
            ActiveInfo.getInstance().postActiveInfo();
            return null;
        }

        @Override
        protected void onPostExecute(Void result) {
        }
    }

返回均为空值, 在 doInBackground中, 需要注明 return null.

OK, Enjoy It.
