问题描述

我有这样的Andr​​oid应用程序，需要通过互联网从远程服务器加载数据。此更新-functionaliy显然需要设备不仅可连接到某些类型的网络，但也到互联网。

i have this android application that requires to load data from a remote server via the internet. this update-functionaliy obviously requires the device to not only be connected to some kind of network, but also to the internet.
