Question

我尝试使用谷歌搜索，但我发现的只是Adobe和Freshplanets NetworkInfo ANE的NetworkInfo。由于某种原因，NetworkInfo无法正常工作，而且newplanets network-info API无法做到这一点。还有其他方法可以完成这项任务吗？

我从使用networkInfo的链接下载了此示例：[http://www.adobe.com/devnet/air/native-extensions-for-air/extensions/networkinfo.html][1]

以下是主要类在上例中的代码：

当我发布apk并在我的设备上运行它。什么都没有，只有白色。

所有移动设备均不支持

NetworkInfo 。轮询 isSupported 标记以查看您是否有权访问。如果您这样做，只需致电 findInterfaces() 即可检索NetworkInterface个对象。
