android - 在android中检测网络类型(TelephonyManager)的变化

Question

我希望我的应用在 networkType 更改时自动通知用户(例如从 EDGE 到 3G 或 3G 到 1XRTT 等)。使用 getNetworkType() 方法，我必须不断检查 networkType 的变化。当检测到变化时，是否有某种 Intent 在整个系统中广播。

Answer 1

查看 ConnectivityManger.CONNECTIVITY_ACTION Ref

来自文档

A change in network connectivity has occurred. A default connection has either been established or lost. The NetworkInfo for the affected network is sent as an extra; it should be consulted to see what kind of connectivity event occurred.
