我有一个是从服务器下载的文件服务。我警告用户只下载文件通过无线网络下载开始前。

I have a Service that is downloading a file from a server. I warn the user to only download the file over Wireless LAN before the download starts.

我的问题是，我的下载卡，如果我失去了网络连接。有没有办法来监听变化的网络连接，或者如果它完全失去了什么？

My problem is that my download gets stuck if I loose the network connection. Is there a way to listen for changes in network connection or if it is lost entirely?

推荐答案

倾听CONNECTIVITY_ACTION

这看起来不错sample code 。这里是一个片段：

This looks like good sample code. Here is a snippet:

BroadcastReceiver networkStateReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { Log.w("Network Listener", "Network Type Changed"); } }; IntentFilter filter = new IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION); registerReceiver(networkStateReceiver, filter);
