Android专业获取设备信息如：AndroidID、唯一设备ID、制造商、型号、版本号、版本码等

• 在开发app中很多时候需要获取设备的基本信息等运用到项目中，就需要一些方法获取，网上资源中方法五花八门，有的还获取不到，令人头大，话不多说，鄙人整理了一套方法，话不多说真机测试如下》上图：
• 接下来就是代码片段了
• 第一步接口方法类：DeviceUtils调用方法：DeviceUtils deviceUtils=new DeviceUtils(this);//实例化
• 方法调用介绍
• // LogTools.e(“获取设备手机制造商:”+ deviceUtils.getManufacturer());
  // LogTools.e(“获取设备AndroidID:”+deviceUtils.getAndroidID());
  // LogTools.e(“获取设备型号:”+deviceUtils.getModel());
  // LogTools.e(“获取唯一设备 ID:”+deviceUtils.getUniqueDeviceId());
  // LogTools.e(“获取设备 AppVersionCode:”+deviceUtils.getVersionCode());
  // LogTools.e(“获取唯一设备 AppVersionName:”+deviceUtils.getVerName());
  // LogTools.e(“获取设备系统版本号:”+ deviceUtils.getSDKVersionName());
  // LogTools.e(“获取设备系统版本码:”+deviceUtils.getSDKVersionCode());
  接下来就只需要傻瓜式复制粘贴就好
