我的使用：
@TargetApi(21)
private fun getMobileNetWork() {
connectivityManager = getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
val builder = NetworkRequest.Builder()
builder.addCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET)
builder.addTransportType(NetworkCapabilities.TRANSPORT_CELLULAR)//TRANSPORT_WIFI
val build = builder.build()
connectivityManager!!.requestNetwork(build, networkCallback)
}
val networkCallback = object : ConnectivityManager.NetworkCallback() {
override fun onAvailable(network: Network) {
super.onAvailable(network)
//Use the network to do your thing
}
override fun onLost(network: Network?) {
super.onLost(network)
}
override fun onUnavailable() {
super.onUnavailable()
}
}
okhttp3中的網絡使用：
val builder = OkHttpClient.Builder()
.connectTimeout(15L, TimeUnit.SECONDS)
.readTimeout(20L, TimeUnit.SECONDS)
.writeTimeout(15L, TimeUnit.SECONDS)
.socketFactory(network.socketFactory)
.dns {
network.getAllByName(it).asList()
}

您可以使用 ConnectivityManager 檢查哪種網絡類型可用，如果 wifi 已連接，請調用您的 api，否則向用戶顯示對話框以通知他此 api 需要打開 wifi 或相反。
您可以使用 Connectivity 類來檢查網絡
public class Connectivity {
public static NetworkInfo getNetworkInfo(Context context){
ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
return cm.getActiveNetworkInfo();
}
public static boolean isConnected(Context context){
NetworkInfo info = Connectivity.getNetworkInfo(context);
return (info != null && info.isConnected());
}
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);
}
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
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;
}
}
}
檢查可用的網絡類型
if (isConnectedWifi(ctx) {
// Call api
}else if (isConnectedMobile(ctx)){
// Show dialog to user to inform him that this api required open wifi
}else{
//
}
