Detect network connection type on Android

Question

How do you detect the network connection type on Android   Is it through ConnectivityManager getActiveNetworkInfo   getType    and is the answer limited to Wifi and mobile

Shown below different ways to do that  Please  note that there are a lot of network types in ConnectivityManager class  Also  if API    21  you can check the network types in NetworkCapabilities class       ConnectivityMonitor connectivityMonitor   ConnectivityMonitor getInstance this       boolean isWiFiConnected   connectivityMonitor isWifiConnection        boolean isMobileConnected   connectivityMonitor isConnected ConnectivityManager TYPE MOBILE       Log e TAG   onCreate  isWiFiConnected     isWiFiConnected       Log e TAG   onCreate  isMobileConnected     isMobileConnected       ConnectivityMonitor Listener connectivityListener   new ConnectivityMonitor Listener              Override         public void onConnectivityChanged boolean connected   Nullable NetworkInfo networkInfo                Log e TAG   onConnectivityChanged  connected     connected               Log e TAG   onConnectivityChanged  networkInfo     networkInfo               if  networkInfo    null                    boolean isWiFiConnected   networkInfo getType      NetworkCapabilities TRANSPORT WIFI                  boolean isMobileConnected   networkInfo getType      NetworkCapabilities TRANSPORT CELLULAR                  Log e TAG   onConnectivityChanged  isWiFiConnected     isWiFiConnected                   Log e TAG   onConnectivityChanged  isMobileConnected     isMobileConnected                                      connectivityMonitor addListener connectivityListener

Currently  only MOBILE and WIFI is supported  Take a look and human readable type function

Emil s answer above is brilliant   Small addition  We should ideally use TelephonyManager to detect network types  So the above should instead read          Check if there is fast connectivity     param context     return     public static boolean isConnectedFast Context context       ConnectivityManager cm    ConnectivityManager  context getSystemService Context CONNECTIVITY SERVICE       NetworkInfo info   cm getActiveNetworkInfo        TelephonyManager tm    TelephonyManager  context getSystemService Context TELEPHONY SERVICE       return  info    null  amp  amp  info isConnected    amp  amp  Connectivity isConnectionFast info getType    tm getNetworkType

On top of Emil s awsome answer I d like to add one more method  for checking if you actually have Internet access as you could have data set to off on your phone    public static boolean hasInternetAccess Context c       TelephonyManager tm    TelephonyManager  c getSystemService Context TELEPHONY SERVICE       if isConnected c   amp  amp  tm getDataState      TelephonyManager DATA CONNECTED         return true      else         return false      Note that this is only for checking if theres a cellular data connection and will return false if you have WiFi connected  as the cellular data is off when WiFi is connected

To get a more precise  and user friendly  information about connection type  You can use this code  derived from a  hide method in TelephonyManager java    This method returns a String describing the current connection type   i e  one of    WIFI     2G     3G     4G     5G     -   not connected  or      unknown   Remark  This code requires API 25   but you can easily support older versions by using int instead of const   See comments in code    public static String getNetworkClass Context context        ConnectivityManager cm    ConnectivityManager  context getSystemService Context CONNECTIVITY SERVICE             NetworkInfo info   cm getActiveNetworkInfo        if  info    null     info isConnected            return  -      not connected     if  info getType      ConnectivityManager TYPE WIFI          return  WIFI       if  info getType      ConnectivityManager TYPE MOBILE            int networkType   info getSubtype            switch  networkType                case TelephonyManager NETWORK TYPE GPRS              case TelephonyManager NETWORK TYPE EDGE              case TelephonyManager NETWORK TYPE CDMA              case TelephonyManager NETWORK TYPE 1xRTT              case TelephonyManager NETWORK TYPE IDEN         api lt  8  replace by 11             case TelephonyManager NETWORK TYPE GSM          api lt 25  replace by 16                 return  2G               case TelephonyManager NETWORK TYPE UMTS              case TelephonyManager NETWORK TYPE EVDO 0              case TelephonyManager NETWORK TYPE EVDO A              case TelephonyManager NETWORK TYPE HSDPA              case TelephonyManager NETWORK TYPE HSUPA              case TelephonyManager NETWORK TYPE HSPA              case TelephonyManager NETWORK TYPE EVDO B       api lt  9  replace by 12             case TelephonyManager NETWORK TYPE EHRPD        api lt 11  replace by 14             case TelephonyManager NETWORK TYPE HSPAP        api lt 13  replace by 15             case TelephonyManager NETWORK TYPE TD SCDMA     api lt 25  replace by 17                 return  3G               case TelephonyManager NETWORK TYPE LTE          api lt 11  replace by 13             case TelephonyManager NETWORK TYPE IWLAN        api lt 25  replace by 18             case 19     LTE CA                 return  4G               case TelephonyManager NETWORK TYPE NR           api lt 29  replace by 20                 return  5G               default                  return                           return
