Android判斷使用者2G/3G/4G移動資料網路

NO IMAGE

在做 Android App 的時候,為了給使用者省流量,為了不激起使用者的憤怒,為了更好的使用者體驗,是需要根據使用者當前網路情況來做一些調整的,也可以在 App 的設定模組裡,讓使用者自己選擇,在 2G / 3G / 4G 網路條件下,是否允許請求一些流量比較大的資料。

通過 Android 提供的 TelephonyManager 和 ConnectivityManager 都可以獲取到 NetworksInfo 物件,可以通過 getType() 獲取型別,判斷是 wifi 還是 mobile ,如果是 mobile ,可以通過 NetworksInfo 物件的 getSubType() 和 getSubTypeName() 可以獲取到對於的網路型別和名字。

網路型別和名字定義在 TelephonyManager 類裡。


/** 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;

看到這個程式碼和註釋,相信沒有這方面知識的人很難看懂,都啥玩意?這注釋跟沒註釋有啥區別?!就是讓人看著更加鬧心而已。所以說,註釋對閱讀程式碼的人很重 要。當然這些東西可能太專業了,寫這些程式碼的人估計是想寫也不知道該怎麼了,得寫多大一坨啊?!我在最後會貼上一些我整理的資料,可以供大家參考一下,不 是很詳細,也不專業,就是大概有個印象。

TelephonyManager 還提供了 getNetworkTypeName(int type) 的方法,這個方法可以返回一個字串,但是資訊量不大。

那怎麼判斷是 2G , 3G 還是 4G 網路呢?TelephonyManager 還提供了另外一個方法,getNetworkClass(int networkType) ,但這個方法被隱藏掉了,我把程式碼貼一下。


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; 
} 
} 

然後下面是這幾個常量的值。


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

不知道為啥要把這些東西給隱藏起來,不靠譜?還是其他的更好的方式?!不知道,先這樣吧,現在通過上面的手段,是可以知道使用者用的是什麼網路,當 然也可以區分出來使用者使用的是 2G , 3G 還是 4G 了。當然,你獲取到這些資料後,你也可以推算出使用者用的是哪家公司的網路,移動的,聯通的,還是電信的,當然,只在中國。而且虛擬運營商開始真正上市後, 這個就區分不出來是京東的,還是國美,蘇寧的了,但是你可以知道你的手機號用的是聯通的網還是移動的網。

最後貼上我收集整理的一些資料,可以參考一下。
