How to find network type is 2G/3G/4G exactly

[Bunty syed]

HI,

I want to find if the connected network falls under 2G ,3G or 4G..

I went through ConnectivityManager / TelephonyManager but it gives
network type like gprs,edge,etc...

In device,we will find a tick mark like use only 2G network.

Can anybody tell me how native android decides that whether the
connected network falls under 2G..

I think u can write some logic based on the approximate bit rates assumed for edge,gprs,umt,etc....

Regards,

Ashiq

Hi,

native RIL requests involved for identyfing network type are:

RIL_REQUEST_REGISTRATION_STATE
RIL_REQUEST_GPRS_REGISTRATION_STATE

What these requests do depends on the native RIL driver, but you can
find the prototype of the requests in
hardware/ril/include/telephony/ril.h

Hi,

 

Please try below method, but it's hard to find to  real network type. As you may know, some network type belong to both 2g and 3g.

 

public static boolean is3G(int networkType){

        if (networkType == ConnectivityManager.TYPE_MOBILE) {

            TelephonyManager telephonyManager = (TelephonyManager) AppContent.getInstance().getSystemService(Context.TELEPHONY_SERVICE);

            networkType = telephonyManager.getNetworkType();

        }

        return (networkType == TelephonyManager.NETWORK_TYPE_UMTS

                || networkType == TelephonyManager.NETWORK_TYPE_HSDPA

                || networkType == TelephonyManager.NETWORK_TYPE_CDMA

                || networkType == TelephonyManager.NETWORK_TYPE_EVDO_0

                || networkType == TelephonyManager.NETWORK_TYPE_EVDO_A

                || networkType == TelephonyManager.NETWORK_TYPE_UNKNOWN);

    }
