Android 判断用户2G/3G/4G移动数据网络
在做 Android App 的时候，为了给用户省流量，为了不激起用户的愤怒，为了更好的用户体验，是需要根据用户当前网络情况来做一些调整的，也可以在 App 的设置模块里，让用户自己选择，在 2G / 3G / 4G 网络条件下，是否允许请求一些流量比较大的数据。
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。 /** Network type is unknown */public static final int NETWORK_TYPE_UNKNOWN = 0;/** Current network is GPRS */public static final int NETWORK_TYPE_GPRS = 1;/** Current network is EDGE */public static final int NETWORK_TYPE_EDGE = 2;/** Current network is UMTS */public static final int NETWORK_TYPE_UMTS = 3;/** Current network is CDMA: Either IS95A or IS95B*/public static final int NETWORK_TYPE_CDMA = 4;/** Current network is EVDO revision 0*/public static final int NETWORK_TYPE_EVDO_0 = 5;/** Current network is EVDO revision A*/public static final int NETWORK_TYPE_EVDO_A = 6;/** Current network is 1xRTT*/public static final int NETWORK_TYPE_1xRTT = 7;/** Current network is HSDPA */public static final int NETWORK_TYPE_HSDPA = 8;/** Current network is HSUPA */public static final int NETWORK_TYPE_HSUPA = 9;/** Current network is HSPA */public static final int NETWORK_TYPE_HSPA = 10;/** Current network is iDen */public static final int NETWORK_TYPE_IDEN = 11;/** Current network is EVDO revision B*/public static final int NETWORK_TYPE_EVDO_B = 12;/** Current network is LTE */public static final int NETWORK_TYPE_LTE = 13;/** Current network is eHRPD */public static final int NETWORK_TYPE_EHRPD = 14;/** Current network is HSPA+ */public static final int NETWORK_TYPE_HSPAP = 15; 看到这个代码和注释，相信没有这方面知识的人很难看懂，都啥玩意？这注释跟没注释有啥区别？！就是让人看着更加闹心而已。所以说，注释对阅读代码的人很重 要。当然这些东西可能太专业了，写这些代码的人估计是想写也不知道该怎么了，得写多大一坨啊？！我在最后会贴上一些我整理的资料，可以供大家参考一下，不 是很详细，也不专业，就是大概有个印象。
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。 public static int getNetworkClass(int networkType) { switch (networkType) { case NETWORK_TYPE_GPRS: case NETWORK_TYPE_EDGE: case NETWORK_TYPE_CDMA: case NETWORK_TYPE_1xRTT: case NETWORK_TYPE_IDEN: return NETWORK_CLASS_2_G; case NETWORK_TYPE_UMTS: case NETWORK_TYPE_EVDO_0: case NETWORK_TYPE_EVDO_A: case NETWORK_TYPE_HSDPA: case NETWORK_TYPE_HSUPA: case NETWORK_TYPE_HSPA: case NETWORK_TYPE_EVDO_B: case NETWORK_TYPE_EHRPD: case NETWORK_TYPE_HSPAP: return NETWORK_CLASS_3_G; case NETWORK_TYPE_LTE: return NETWORK_CLASS_4_G; default: return NETWORK_CLASS_UNKNOWN; } } 然后下面是这几个常量的值。 /** Unknown network class. [email protected]} */ public static final int NETWORK_CLASS_UNKNOWN = 0; /** Class of broadly defined "2G" networks. [email protected]} */ public static final int NETWORK_CLASS_2_G = 1; /** Class of broadly defined "3G" networks. [email protected]} */ public static final int NETWORK_CLASS_3_G = 2; /** Class of broadly defined "4G" networks. [email protected]} */ public static final int NETWORK_CLASS_4_G = 3; 不知道为啥要把这些东西给隐藏起来，然道是不靠谱？！还是其他的更好的方式？！不知道，先这样吧，现在通过上面的手段，是可以知道用户用的是什么网络，当 然也可以区分出来用户使用的是 2G ， 3G 还是 4G 了。当然，你获取到这些数据后，你也可以推算出用户用的是哪家公司的网络，移动的，联通的，还是电信的，当然，只在中国。而且虚拟运营商开始真正上市后， 这个就区分不出来是京东的，还是国美，苏宁的了，但是你可以知道你的手机号用的是联通的网还是移动的网。
最后贴上我收集整理的一些资料，可以参考一下。

微信扫一扫中国移动2G用户提高网速的方法——信不信由你——一定是心理作用
大家都知道移动2G的网速用普通话说那叫一个[哔]。。。每次上网刷图总要情不自禁的说一句[哔][哔][哔][哔]。。。。但因为和手机号有感情等种种原因很多人还是选择使用移动2G的号码。
最近听到一个提高移动2G网速的野方法：
一般来说移动2G的接入点是CMNET和CMWAP，大家都比较熟悉了。移动在推出3G业务的时候增加了一个新的接入点CMTDS，具体的内容就不多说了，可以自行百度或者Google，但CMTDS的百度百科里有一句话：“CMTDS适用于USIM卡（3G卡），普通2G卡采用CMTDS接入相当于使用CMNET接入点。”
CMTDS接入点是为3G而设计，原则上说比2G更加稳定。
那2G用户用CMTDS的接入点的网速呢？
设置很简单：
一台智能手机，IOS Android均可，不需要越狱或者root。进入“设置” - “移动网络”- “接入点名称” -
“新建Apn” （具体手机具体菜单选项不同）
第一项名称写 cmtds （其实可以随意）
第二项apn里面写 CMTDS 注意大写
（如果有朋友设置后不能上的，请先还原一下网络设置，再重新启动后试试）
速度测试：
在同一个地方下载同一个文件
默认CMNET，平均下载速度15-20k/s
CMTDS，平均下载速度20-25k/s
好像有点提速哦。。。
说原理，一种说法是，满大街的人用的接入点基本上都是CMNET或CMWAP，尤其是在网络繁忙时段极易造成网络堵塞，而CMTDS这个接入点用的人非常少，所以你懂的。。。在地铁里效果尤其明显。
接入点和信号没关系，信号取决于手机的基带，没信号就是没信号，想快也没办法。以上测试是同一信号区间的网速对比测试。
关于资费。特地去移动上查了一下。我是动感地带，有几百兆的流量包月。用CMTDS接入显示的是CMWAP接入，扣的是包月套餐，不另外扣费。
3. 耗电，基本和CMNET一样。
注：以上都是个人测试，网上也有很多人反馈这个效果不明显。
所以。。。亲自己决定，大家随便看看哈~~~
以上网友发言只代表其个人观点，不代表新浪网的观点或立场。移动的2G3G4G是如何区分的？
有谁知道移动的2G3G4G是如何区分的？3G要不要开通？我手机支持3g为啥用的不是3g。到底有啥区别？搞不懂
按使用者来说：
2G就是GSM，CDMA移动电话，可以移动通信，收发短信和一些低速的上网GPRS。这一代主要是提供语音业务。传输方式采用电路域。
3G就是除了打电话之外采用最新技术来实现速率的提高。比2G要高十倍左右，理论上家里2M ADSL还快，当然手机要支持3G才行。这一代增加了对高速上网即数据业务的支持，使用基于IP的网络或者是和电路域混合的网络，将语音和数据分开。
4G就是3G的下一代，会提供更加快速的上网，而且可以高速移动过程中不会断网。是从以前的不同的3G标准演进到TLE。这一代采用纯IP网络来承载。虽然增加频段可以增加用户的上网速率，但频段是稀有资源，实现更高速的上网需要采用像码分多址，频分复用等技术。
3G是不需要开通的，只需要换相对应网络的sim卡，你的手机不能用3G网络应该是手机网络制式的问题。
