Android如何检测网络的类型为3G、2G、wap、wifi

关于Android如何检测网络的类型，网上代码很多，但是有用的精品不多，前段时间，因为做项目需要涉及到具体网络类型的检查，特别是区分2G网络是为wap，还是net,类型，因为wap类型，需要配置代理上网，基于此，我将自己实现的过程代码记录下来：

1、定义常量来标识几种网络类型

\[java\] [view plain][] [copy][view plain]

1.  /\*\* 没有网络 \*/
2.  publicstaticfinalint NETWORKTYPE\_INVALID = 0; 
3.  /\*\* wap网络 \*/
4.  publicstaticfinalint NETWORKTYPE\_WAP = 1; 
5.  /\*\* 2G网络 \*/
6.  publicstaticfinalint NETWORKTYPE\_2G = 2;

\[java\] [view plain][] [copy][view plain]

1.  /\*\* 3G和3G以上网络，或统称为快速网络 \*/
2.  publicstaticfinalint NETWORKTYPE\_3G = 3;

\[java\] [view plain][] [copy][view plain]

1.  /\*\* wifi网络 \*/
2.  publicstaticfinalint NETWORKTYPE\_WIFI = 4;

2、判断是否是FastMobileNetWork，将3G或者3G以上的网络称为快速网络

\[java\] [view plain][] [copy][view plain]

1.  privatestaticboolean isFastMobileNetwork(Context context) \{ 
2.  elephonyManager telephonyManager = (TelephonyManager)context.getSystemService(Context.TELEPHONY\_SERVICE); 
3.  switch (telephonyManager.getNetworkType()) \{ 
4.  case TelephonyManager.NETWORK\_TYPE\_1xRTT: 
5.  returnfalse; // ~ 50-100 kbps
6.  case TelephonyManager.NETWORK\_TYPE\_CDMA: 
7.  returnfalse; // ~ 14-64 kbps
8.  case TelephonyManager.NETWORK\_TYPE\_EDGE: 
9.  returnfalse; // ~ 50-100 kbps
10. case TelephonyManager.NETWORK\_TYPE\_EVDO\_0: 
11. returntrue; // ~ 400-1000 kbps
12. case TelephonyManager.NETWORK\_TYPE\_EVDO\_A: 
13. returntrue; // ~ 600-1400 kbps
14. case TelephonyManager.NETWORK\_TYPE\_GPRS: 
15. returnfalse; // ~ 100 kbps
16. case TelephonyManager.NETWORK\_TYPE\_HSDPA: 
17. returntrue; // ~ 2-14 Mbps
18. case TelephonyManager.NETWORK\_TYPE\_HSPA: 
19. returntrue; // ~ 700-1700 kbps
20. case TelephonyManager.NETWORK\_TYPE\_HSUPA: 
21. returntrue; // ~ 1-23 Mbps
22. case TelephonyManager.NETWORK\_TYPE\_UMTS: 
23. returntrue; // ~ 400-7000 kbps
24. case TelephonyManager.NETWORK\_TYPE\_EHRPD: 
25. returntrue; // ~ 1-2 Mbps
26. case TelephonyManager.NETWORK\_TYPE\_EVDO\_B: 
27. returntrue; // ~ 5 Mbps
28. case TelephonyManager.NETWORK\_TYPE\_HSPAP: 
29. returntrue; // ~ 10-20 Mbps
30. case TelephonyManager.NETWORK\_TYPE\_IDEN: 
31. returnfalse; // ~25 kbps
32. case TelephonyManager.NETWORK\_TYPE\_LTE: 
33. returntrue; // ~ 10+ Mbps
34. case TelephonyManager.NETWORK\_TYPE\_UNKNOWN: 
35. returnfalse; 
36. default: 
37. returnfalse; 
38.  \} 
39. \}

3、获取网络类型是否是2G、3G、wap、wifi等

\[java\] [view plain][] [copy][view plain]

1.  /\*\*
2.   \* 获取网络状态，wifi,wap,2g,3g.
3.   \*
4.   \* @param context 上下文
5.   \* @return int 网络状态 \{@link \#NETWORKTYPE\_2G\},\{@link \#NETWORKTYPE\_3G\}, \*\{@link \#NETWORKTYPE\_INVALID\},\{@link \#NETWORKTYPE\_WAP\}\* <p>\{@link \#NETWORKTYPE\_WIFI\}
6.   \*/
7.  
8.  publicstaticint getNetWorkType(Context context) \{ 
9.  
10.  ConnectivityManager manager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY\_SERVICE); 
11.  NetworkInfo networkInfo = manager.getActiveNetworkInfo(); 
12. 
13. if (networkInfo != null && networkInfo.isConnected()) \{ 
14.  String type = networkInfo.getTypeName(); 
15. 
16. if (type.equalsIgnoreCase("WIFI")) \{ 
17.  mNetWorkType = NETWORKTYPE\_WIFI; 
18.  \} elseif (type.equalsIgnoreCase("MOBILE")) \{ 
19.  String proxyHost = android.net.Proxy.getDefaultHost(); 
20. 
21.  mNetWorkType = TextUtils.isEmpty(proxyHost) 
22.  ? (isFastMobileNetwork(context) ? NETWORKTYPE\_3G : NETWORKTYPE\_2G) 
23.  : NETWORKTYPE\_WAP; 
24.  \} 
25.  \} else \{ 
26.  mNetWorkType = NETWORKTYPE\_INVALID; 
27.  \} 
28. 
29. return mNetWorkType; 
30.  \} 
31.
