API 29中已弃用getActiveNetworkInfo() [英] getActiveNetworkInfo() is deprecated in API 29

问题描述

我正在使用一个代码检查用户是否已激活互联网，但是在定位了sdk29之后，以下功能就被弃用了

I am using a code that check if user has internet active or not but after targeting sdk29 the functions bellow became deprecated

NetworkInfo

NetworkInfo

NetworkInfo.isConnected()

NetworkInfo.isConnected()

getActiveNetworkInfo()

getActiveNetworkInfo()

这是代码:

public static boolean isNetworkAvailable(Context context) {
    if(context == null) { return false; }
    ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    // if no network is available networkInfo will be null, otherwise check if we are connected
    try {
        NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
        if (activeNetworkInfo != null && activeNetworkInfo.isConnected()) {
            Log.i("update_statut","Network is available : true");
            return true;
        }
    } catch (Exception e) {
        Log.i("update_statut",""+ e.getMessage());
    }
    Log.i("update_statut","Network is available : FALSE ");
    return false;
}

推荐答案

我终于找到了可以在所有API上使用的代码，以防万一有人需要

I have finally found a code that works on all APIs in case anybody want it

NetworkCapabilities在API 29中并未被弃用，但它需要API 21，因此我仅在API 29上对其进行了调用.

NetworkCapabilities is not deprecated in API 29 but it requires API 21 so I have called it on API 29 only.

然而，仅在API 29中弃用了getActiveNetworkInfo()，并且只能在所有API上使用，因此我们可以在所有29以下的api中使用它

However getActiveNetworkInfo() is deprecated only in API 29 and works on all APIs , so we can use it in all apis bellow 29

这是代码

    public static boolean isNetworkAvailable(Context context) {
    if(context == null)  return false;


    ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);

    if (connectivityManager != null) {


    if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
            NetworkCapabilities capabilities = connectivityManager.getNetworkCapabilities(connectivityManager.getActiveNetwork());
            if (capabilities != null) {
                if (capabilities.hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR)) {
                    return true;
                } else if (capabilities.hasTransport(NetworkCapabilities.TRANSPORT_WIFI)) {
                    return true;
                }  else if (capabilities.hasTransport(NetworkCapabilities.TRANSPORT_ETHERNET)){
                    return true;
                }
            }
        }

    else {

        try {
            NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
            if (activeNetworkInfo != null && activeNetworkInfo.isConnected()) {
                Log.i("update_statut", "Network is available : true");
                return true;
            }
        } catch (Exception e) {
            Log.i("update_statut", "" + e.getMessage());
        }
    }
}
    Log.i("update_statut","Network is available : FALSE ");
    return false;
}
