get internet speed (WIFI & Data)

问题:

I am making an App and I need to get the internet speed!I can find the wifi speed with WifiInfo clasd but I couldn't find any code or library to get the mobile data speed!
Should I use libraries or there is classes in Android available?

It is hard to determine the mobile speed precisely, but you can estimate the speed based on the connectivity type (EDGE, HSPA):

public static boolean isConnectedFast(final Context context) {
    final NetworkInfo info = getNetworkInfo(context);
    return (info != null) && info.isConnected() && isConnectionFast(info.getType(), info.getSubtype());
}

public static boolean isConnectionFast(final int type, final int subType) {
    if (type == ConnectivityManager.TYPE_WIFI) {
        return true;
    } else if (type == ConnectivityManager.TYPE_MOBILE) {
        switch (subType) {
            case TelephonyManager.NETWORK_TYPE_1xRTT:
                return false; // ~ 50-100 kbps
            case TelephonyManager.NETWORK_TYPE_CDMA:
                return false; // ~ 14-64 kbps
            case TelephonyManager.NETWORK_TYPE_EDGE:
                return false; // ~ 50-100 kbps
            case TelephonyManager.NETWORK_TYPE_EVDO_0:
                return true; // ~ 400-1000 kbps
            case TelephonyManager.NETWORK_TYPE_EVDO_A:
                return true; // ~ 600-1400 kbps
            case TelephonyManager.NETWORK_TYPE_GPRS:
                return false; // ~ 100 kbps
            case TelephonyManager.NETWORK_TYPE_HSDPA:
                return true; // ~ 2-14 Mbps
            case TelephonyManager.NETWORK_TYPE_HSPA:
                return true; // ~ 700-1700 kbps
            case TelephonyManager.NETWORK_TYPE_HSUPA:
                return true; // ~ 1-23 Mbps
            case TelephonyManager.NETWORK_TYPE_UMTS:
                return true; // ~ 400-7000 kbps
        /*
         * Above API level 7, make sure to set android:targetSdkVersion
         * to appropriate level to use these
         */
            case TelephonyManager.NETWORK_TYPE_EHRPD: // API level 11
                return true; // ~ 1-2 Mbps
            case TelephonyManager.NETWORK_TYPE_EVDO_B: // API level 9
                return true; // ~ 5 Mbps
            case TelephonyManager.NETWORK_TYPE_HSPAP: // API level 13
                return true; // ~ 10-20 Mbps
            case TelephonyManager.NETWORK_TYPE_IDEN: // API level 8
                return false; // ~25 kbps
            case TelephonyManager.NETWORK_TYPE_LTE: // API level 11
                return true; // ~ 10+ Mbps
            // Unknown
            case TelephonyManager.NETWORK_TYPE_UNKNOWN:
            default:
                return false;
        }
    } else {
        return false;
    }
}

There's no Android lib or class that provide this. wifiInfo.getLinkSpeed returns the max speed of the network and it changes from time to time.

Though i found something in FB SDK to get the speed of internet.

ConnectionQuality cq = ConnectionClassManager.getInstance().getCurrentBandwidthQuality();

here's the github repo: https://github.com/facebook/network-connection-class

Use this code

WifiManager wifiManager = (WifiManager)context.getSystemService(Context.WIFI_SERVICE);
int linkSpeed = wifiManager.getConnectionInfo().getRssi();
