如何以编程方式检查Android的互联网连接的availibilty？ [英] How to programmatically check availibilty of internet connection in Android?

问题描述

我要检查编程是否有android手机/仿真器连接到互联网。所以，一旦我相信，互联网连接是present然后我会打个电话到互联网。

I want to check programmatically whether there is an internet connection in android phone/emulator. So that once I am sure that an internet connection is present then I'll make a call to the internet.

因此​​，它像嘿仿真器如果你有一个互联网连接，那么请打开这个网页，否则doSomeThingElse（）;！

So its like "Hey emulator! If you have an internet connection, then please open this page, else doSomeThingElse();"

希望得到您的想法。我会强烈AP preciate快速反应我很早就需要它。

hope you get the idea. I would highly appreciate a quick response I need it quite early.

推荐答案

我实现了自己的方式：

/*
 * isOnline - Check if there is a NetworkConnection
 * @return boolean
 */
protected boolean isOnline() {
    ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo netInfo = cm.getActiveNetworkInfo();
    if (netInfo != null && netInfo.isConnected()) {
        return true;
    } else {
        return false;
    }
}

请注意，这是一个NetworkConnection-检查。如果有一个NetworkConnection它不必是一个InternetConnection

Be aware of that this is a NetworkConnection-Check. If there is a NetworkConnection it doesn't have to be a InternetConnection.
