getActiveNetworkInfo() is deprecated in API 29 [duplicate]

Question

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.isConnected()

getActiveNetworkInfo()

Here is the code :

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; } 

Answer 1

It's deprecated base on Google Document

• getActiveNetworkInfo is deprecated on API 29.
• getAllNetworkInfo is deprecated on API 23.

So, If you want to find the Network Connection status, you can use this code.

kotlin :

private fun isNetworkAvailable(context: Context): Boolean {     val connectivityManager = context.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager     if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {         val nw      = connectivityManager.activeNetwork ?: return false         val actNw = connectivityManager.getNetworkCapabilities(nw) ?: return false         return when {             actNw.hasTransport(NetworkCapabilities.TRANSPORT_WIFI) -> true             actNw.hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR) -> true             //for other device how are able to connect with Ethernet             actNw.hasTransport(NetworkCapabilities.TRANSPORT_ETHERNET) -> true             //for check internet over Bluetooth             actNw.hasTransport(NetworkCapabilities.TRANSPORT_BLUETOOTH) -> true             else -> false         }     } else {         val nwInfo = connectivityManager.activeNetworkInfo ?: return false         return nwInfo.isConnected     } } 

Java :

private Boolean isNetworkAvailable(Application application) {     ConnectivityManager connectivityManager = (ConnectivityManager) application.getSystemService(Context.CONNECTIVITY_SERVICE);     if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {         Network nw = connectivityManager.getActiveNetwork();         if (nw == null) return false;         NetworkCapabilities actNw = connectivityManager.getNetworkCapabilities(nw);         return actNw != null && (actNw.hasTransport(NetworkCapabilities.TRANSPORT_WIFI) || actNw.hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR) || actNw.hasTransport(NetworkCapabilities.TRANSPORT_ETHERNET) || actNw.hasTransport(NetworkCapabilities.TRANSPORT_BLUETOOTH));     } else {         NetworkInfo nwInfo = connectivityManager.getActiveNetworkInfo();         return nwInfo != null && nwInfo.isConnected();     } } 

you can see all NetworkCapability here.

Answer 2

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

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

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

here's the code

    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; }
