通过 Android 提供的 TelephonyManager 和 ConnectivityManager 都可以获取到 NetworksInfo 对象,可以通过 getType() 获取类型,判断是 wifi 还是 mobile ,如果是 mobile ,可以通过 NetworksInfo 对象的 getSubType() 和 getSubTypeName() 可以获取到对于的网络类型和名字。

网络类型和名字定义在 TelephonyManager 类里。

  1. /** Network type is unknown */
  2. public static final int NETWORK_TYPE_UNKNOWN = 0;
  3. /** Current network is GPRS */
  4. public static final int NETWORK_TYPE_GPRS = 1;
  5. /** Current network is EDGE */
  6. public static final int NETWORK_TYPE_EDGE = 2;
  7. /** Current network is UMTS */
  8. public static final int NETWORK_TYPE_UMTS = 3;
  9. /** Current network is CDMA: Either IS95A or IS95B*/
  10. public static final int NETWORK_TYPE_CDMA = 4;
  11. /** Current network is EVDO revision 0*/
  12. public static final int NETWORK_TYPE_EVDO_0 = 5;
  13. /** Current network is EVDO revision A*/
  14. public static final int NETWORK_TYPE_EVDO_A = 6;
  15. /** Current network is 1xRTT*/
  16. public static final int NETWORK_TYPE_1xRTT = 7;
  17. /** Current network is HSDPA */
  18. public static final int NETWORK_TYPE_HSDPA = 8;
  19. /** Current network is HSUPA */
  20. public static final int NETWORK_TYPE_HSUPA = 9;
  21. /** Current network is HSPA */
  22. public static final int NETWORK_TYPE_HSPA = 10;
  23. /** Current network is iDen */
  24. public static final int NETWORK_TYPE_IDEN = 11;
  25. /** Current network is EVDO revision B*/
  26. public static final int NETWORK_TYPE_EVDO_B = 12;
  27. /** Current network is LTE */
  28. public static final int NETWORK_TYPE_LTE = 13;
  29. /** Current network is eHRPD */
  30. public static final int NETWORK_TYPE_EHRPD = 14;
  31. /** Current network is HSPA+ */
  32. public static final int NETWORK_TYPE_HSPAP = 15;

TelephonyManager 还提供了 getNetworkTypeName(int type) 的方法,这个方法可以返回一个字符串,但是信息量不大。

那怎么判断是 2G , 3G 还是 4G 网络呢?TelephonyManager 还提供了另外一个方法,getNetworkClass(int networkType) ,但这个方法被隐藏掉了,我把代码贴一下。

  1. fun getNetworkClass(int networkType): Int {
  2. return when (networkType) {
  3. NETWORK_TYPE_GPRS,
  4. NETWORK_TYPE_EDGE,
  5. NETWORK_TYPE_CDMA,
  6. NETWORK_TYPE_1xRTT,
  7. NETWORK_TYPE_IDEN-> {NETWORK_CLASS_2_G}
  8. NETWORK_TYPE_UMTS,
  9. NETWORK_TYPE_EVDO_0,
  10. NETWORK_TYPE_EVDO_A,
  11. NETWORK_TYPE_HSDPA,
  12. NETWORK_TYPE_HSUPA,
  13. NETWORK_TYPE_HSPA,
  14. NETWORK_TYPE_EVDO_B,
  15. NETWORK_TYPE_EHRPD,
  16. NETWORK_TYPE_HSPAP-> {NETWORK_CLASS_3_G}
  17. NETWORK_TYPE_LTE-> {NETWORK_CLASS_4_G}
  18. else-> { NETWORK_CLASS_UNKNOWN}
  19. }
  20. }

然后下面是这几个常量的值。

  1. /** Unknown network class. {@hide} */
  2. public static final int NETWORK_CLASS_UNKNOWN = 0;
  3. /** Class of broadly defined "2G" networks. {@hide} */
  4. public static final int NETWORK_CLASS_2_G = 1;
  5. /** Class of broadly defined "3G" networks. {@hide} */
  6. public static final int NETWORK_CLASS_3_G = 2;
  7. /** Class of broadly defined "4G" networks. {@hide} */
  8. public static final int NETWORK_CLASS_4_G = 3;

最后贴上收集整理的一些资料,可以参考一下。

  1. GPRS 2G(2.5) General Packet Radia Service 114kbps
  2. EDGE 2G(2.75G) Enhanced Data Rate for GSM Evolution 384kbps

  5. EVDO_0 3G (EVDO 全程 CDMA2000 1xEV-DO) Evolution - Data Only (Data Optimized) 153.6kps - 2.4mbps 属于3G
  6. EVDO_A 3G 1.8mbps - 3.1mbps 属于3G过渡,3.5G
  7. 1xRTT 2G CDMA2000 1xRTT (RTT - 无线电传输技术) 144kbps 2G的过渡,
  8. HSDPA 3.5G 高速下行分组接入 3.5G WCDMA High Speed Downlink Packet Access 14.4mbps
  9. HSUPA 3.5G High Speed Uplink Packet Access 高速上行链路分组接入 1.4 - 5.8 mbps
  10. HSPA 3G (分HSDPA,HSUPA) High Speed Packet Access
  11. IDEN 2G Integrated Dispatch Enhanced Networks 集成数字增强型网络 (属于2G,来自维基百科)
  12. EVDO_B 3G EV-DO Rev.B 14.7Mbps 下行 3.5G
  13. LTE 4G Long Term Evolution FDD-LTE TDD-LTE , 3G过渡,升级版 LTE Advanced 才是4G
  14. EHRPD 3G CDMA2000LTE 4G的中间产物 Evolved High Rate Packet Data HRPD的升级
  15. HSPAP 3G HSPAP HSDPA 快些
