android 处理网络状态——无网,2g,3g,wifi,ethernet,other

今天在一位很牛逼的学长的博客里面看到了这段代码后，很是激动啊，于是就“偷”了过来，嘿嘿。。。。为自己也为更多需要它的程序媛

直接上代码：

public class GetNetWorkStateActor extends FusionActor {

@Override
public boolean processFusionMessage(FusionMessage msg) {
// TODO Auto-generated method stub
msg.setResponseData(checkNet());
return false;
}

private int checkNet() {
// TODO Auto-generated method stub
ConnectivityManager connectivityManager = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo mobNetInfoActivity = connectivityManager
.getActiveNetworkInfo();
int netFlag = 0;
if (mobNetInfoActivity != null) {

switch (mobNetInfoActivity.getType()) {
case ConnectivityManager.TYPE_ETHERNET:
// ethernet
netFlag = 1;
break;
case ConnectivityManager.TYPE_WIFI:
// wifi
netFlag = 2;
break;
case ConnectivityManager.TYPE_MOBILE:
// gprs
if(isFastMobileNetwork(context)){
//2g
netFlag = 3;
}else{
//3g
netFlag = 4;
}
break;
default:
break;
}
} else {
//no network
netFlag = 0;
}
return netFlag;
}
private static boolean isFastMobileNetwork(Context context) {  
       TelephonyManager telephonyManager = (TelephonyManager) context  
               .getSystemService(Context.TELEPHONY_SERVICE);  
 
       switch (telephonyManager.getNetworkType()) {  
       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  
       case TelephonyManager.NETWORK_TYPE_EHRPD:  
           return true; // ~ 1-2 Mbps  
       case TelephonyManager.NETWORK_TYPE_EVDO_B:  
           return true; // ~ 5 Mbps  
       case TelephonyManager.NETWORK_TYPE_HSPAP:  
           return true; // ~ 10-20 Mbps  
       case TelephonyManager.NETWORK_TYPE_IDEN:  
           return false; // ~25 kbps  
       case TelephonyManager.NETWORK_TYPE_LTE:  
           return true; // ~ 10+ Mbps  
       case TelephonyManager.NETWORK_TYPE_UNKNOWN:  
           return false;  
       default:  
           return false;  
       }  
}
}
