Detectar tipo de conexión de red en Android

186

¿Cómo se detecta el tipo de conexión de red en Android?

¿Ya pasó ConnectivityManager.getActiveNetworkInfo().getType()y la respuesta se limita a Wifi y dispositivos móviles?

Si el problema es encontrar si la red del teléfono está conectada y es lo suficientemente rápida como para satisfacer sus demandas, debe manejar todos los tipos de red devueltos por getSubType().

Me llevó una o dos horas investigar y escribir esta clase para hacer exactamente eso, y pensé en compartirla con otros que pudieran encontrarla útil.

Aquí hay un resumen de la clase , por lo que puede bifurcarlo y editarlo.

package com.emil.android.util;

import android.content.Context;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.telephony.TelephonyManager;

/**
 * Check device's network connectivity and speed 
 * @author emil http://stackoverflow.com/users/220710/emil

 */
public class Connectivity {

    /**
     * Get the network info
     * @param context
     * @return
     */
    public static NetworkInfo getNetworkInfo(Context context){
        ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        return cm.getActiveNetworkInfo();
    }

    /**
     * Check if there is any connectivity
     * @param context
     * @return
     */
    public static boolean isConnected(Context context){
        NetworkInfo info = Connectivity.getNetworkInfo(context);
        return (info != null && info.isConnected());
    }

    /**
     * Check if there is any connectivity to a Wifi network
     * @param context
     * @return
     */
    public static boolean isConnectedWifi(Context context){
        NetworkInfo info = Connectivity.getNetworkInfo(context);
        return (info != null && info.isConnected() && info.getType() == ConnectivityManager.TYPE_WIFI);
    }

    /**

    public static boolean isConnectedMobile(Context context){
        NetworkInfo info = Connectivity.getNetworkInfo(context);
        return (info != null && info.isConnected() && info.getType() == ConnectivityManager.TYPE_MOBILE);
    }

    /**
     * Check if there is fast connectivity
     * @param context
     * @return

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

    /**

    public static boolean isConnectionFast(int type, 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

        }else{
            return false;
        }
    }

}

También asegúrese de agregar este permiso a su AndroidManifest.xml

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>

Gracias. Por cierto, todas las constantes para los tipos de red ( aquí ) son public static final int. Entonces no necesitas hacer el "hack". Solo apunte al SDK más nuevo, el compilador compila los valores reales (enteros) a los que apuntan (no sus instancias) en códigos de bytes.

@LaiVung Cuando respondí esto, acababa de comenzar a codificar para Android y no sabía cómo usar la targetSdkVersionconfiguración. Edité la publicación para eliminar el truco, gracias.

Pero, ¿cómo puedo saber la velocidad del wifi? Porque tal vez descubras que tienes una conexión de alta velocidad pero tu wifi es demasiado lento ...

Como todos los métodos son estáticos, esta clase podría declararse final y tener un constructor privado.
Gabriel
pero esto solo verifica si hay una conexión de red disponible y no si efectivamente existe una conexión a Internet. Por lo tanto, necesitaría hacer ping a un servidor, por ejemplo, para estar 100% seguro.

Para obtener una información más precisa (y fácil de usar) sobre el tipo de conexión. Puede usar este código (derivado de un método @hide en TelephonyManager.java ).

Este método devuelve una cadena que describe el tipo de conexión actual.
es decir, uno de: "WIFI", "2G", "3G", "4G", "5G", "-" (no conectado) o "?" (desconocido)

Observación: este código requiere API 25+, pero puede admitir fácilmente versiones anteriores utilizando int en lugar de const. (Ver comentarios en el código).

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< 8: replace by 11
            case TelephonyManager.NETWORK_TYPE_GSM:      // api<25: replace by 16
                return "2G";
            case TelephonyManager.NETWORK_TYPE_UMTS:
            case TelephonyManager.NETWORK_TYPE_EVDO_0:
            case TelephonyManager.NETWORK_TYPE_EVDO_A:

            case 19: // LTE_CA
                return "4G";
            case TelephonyManager.NETWORK_TYPE_NR:       // api<29: replace by 20
                return "5G";

Puede usar getSubtype () para obtener más detalles. Consulte la diapositiva 9 aquí: http://dl.google.com/io/2009/pres/W_0300_CodingforLife-BatteryLifeThatIs.pdf

ConnectivityManager mConnectivity = null;
TelephonyManager mTelephony = null;
// Skip if no connection, or background data disabled
NetworkInfo info = mConnectivity.getActiveNetworkInfo();
if (info == null || !mConnectivity.getBackgroundDataSetting()) {
    return false;
}

// Only update if WiFi or 3G is connected and not roaming
int netType = info.getType();
int netSubtype = info.getSubtype();
if (netType == ConnectivityManager.TYPE_WIFI) {
    return info.isConnected();
} else if (netType == ConnectivityManager.TYPE_MOBILE
    && netSubtype == TelephonyManager.NETWORK_TYPE_UMTS
    && !mTelephony.isNetworkRoaming()) {
        return info.isConnected();
} else {
    return false;
}

La respuesta de @ Emil arriba es brillante.

Pequeña adición: idealmente deberíamos usar TelephonyManager para detectar tipos de red. Por lo tanto, lo anterior debería leer:

/**
 * 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 && info.isConnected() && Connectivity.isConnectionFast(info.getType(), tm.getNetworkType()));
}

La respuesta de Emil Davtyan es buena, pero se han agregado tipos de red que no se tienen en cuenta en su respuesta. Por lo tanto, isConnectionFast(int type, int subType)puede devolver falso cuando debería ser cierto.

Aquí hay una clase modificada que utiliza la reflexión para dar cuenta de los tipos de red agregados en las API posteriores:

Puede hacer un método personalizado para realizar esta tarea.

  public String getNetworkClass(Context context) {
        TelephonyManager mTelephonyManager = (TelephonyManager)
                context.getSystemService(Context.TELEPHONY_SERVICE);
        int networkType = mTelephonyManager.getNetworkType();

Además de la impresionante respuesta de Emil, me gustaría agregar un método más, para verificar si realmente tiene acceso a Internet, ya que podría tener los datos desactivados en su teléfono.

public static boolean hasInternetAccess(Context c){
    TelephonyManager tm = (TelephonyManager) c.getSystemService(Context.TELEPHONY_SERVICE);
    if(isConnected(c) && tm.getDataState() == TelephonyManager.DATA_CONNECTED)
       return true;
    else
        return false;
}

Tenga en cuenta que esto es solo para verificar si hay una conexión de datos móviles y devolverá falso si tiene WiFi conectado, ya que los datos celulares están apagados cuando WiFi está conectado.

Puedes comprobar así

public void checktype() {
    ConnectivityManager cm = (ConnectivityManager) this.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
    if (activeNetwork != null) { // connected to the internet
        if (activeNetwork.getType() == ConnectivityManager.TYPE_WIFI) {
            // connected to wifi
            Toast.makeText(this, activeNetwork.getTypeName(), Toast.LENGTH_SHORT).show();
        } else if (activeNetwork.getType() == ConnectivityManager.TYPE_MOBILE) {
            // connected to the mobile provider's data plan
            Toast.makeText(this, activeNetwork.getTypeName(), Toast.LENGTH_SHORT).show();
        }
    }
}

Puedes probar esto:

public String ConnectionQuality() {
    NetworkInfo info = getInfo(context);
    if (info == null || !info.isConnected()) {
      return "UNKNOWN";
    }

    if(info.getType() == ConnectivityManager.TYPE_WIFI) {
        WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
        int numberOfLevels = 5;
        WifiInfo wifiInfo = wifiManager.getConnectionInfo();
        int level = WifiManager.calculateSignalLevel(wifiInfo.getRssi(), numberOfLevels);
        if(level == 2 )
                return "POOR";
            else if(level == 3 )
                return "MODERATE";
            else if(level == 4 )
                return "GOOD";
            else if(level == 5 )

A continuación se muestran diferentes formas de hacerlo. Tenga en cuenta que hay muchos tipos de red en la clase ConnectivityManager. Además, si API> = 21, puede verificar los tipos de red en la clase NetworkCapabilities.

    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);
