ConnectivityManager getNetworkInfo(int) 已弃用

问题描述

使用 compileSdkVersion 23，但尝试支持最早的版本 9.

Using compileSdkVersion 23, however trying to support as far back as 9.

getNetworkInfo(int) 在 23 中被弃用.建议使用 getAllNetworks() 和 getNetworkInfo(Network) 代替.但是，这两者都需要至少 API 21.

getNetworkInfo(int) was deprecated in 23. The suggestion was to use getAllNetworks() and getNetworkInfo(Network) instead. However both of these require minimum of API 21.

是否有我们可以在支持包中使用的类来帮助解决这个问题?

Is there a class that we can use in the support package that can assist with this?

我知道在之前提出了一个解决方案，但是我对 API 最低要求 9 的挑战带来了问题.

I know that a solution was proposed before, however the challenge of my minimum API requirements of 9 poses a problem.

推荐答案

您可以使用:

getActiveNetworkInfo();

ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
if (activeNetwork != null) {
    // connected to the internet
    if (activeNetwork.getType() == ConnectivityManager.TYPE_WIFI) {
        // connected to wifi
    } else if (activeNetwork.getType() == ConnectivityManager.TYPE_MOBILE) {
        // connected to mobile data
    }
} else {
    // not connected to the internet
}

或者在开关盒中

ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
if (activeNetwork != null) {
    // connected to the internet
    switch (activeNetwork.getType()) {
        case ConnectivityManager.TYPE_WIFI:
            // connected to wifi
            break;
        case ConnectivityManager.TYPE_MOBILE:
            // connected to mobile data
            break;
        default:
            break;
    }
} else {
    // not connected to the internet
}
