android2.3.5 CDMA/EVDO撥號APN解決方案

更新時間：2013年01月16日 17:16:35 作者：

google提供的android2.3里面，只能在GSM/WCDMA情況下才能從“設(shè)置”->“無線和網(wǎng)絡(luò)”->“移動網(wǎng)絡(luò)”->“接入點名稱”中選擇不同的apn帳號進行撥號連接，而CDMA/EVDO則沒有這個功能,接下來本文介紹一些方法實現(xiàn)這個功能，感興趣的朋友可以了解下

google提供的android2.3里面，只能在GSM/WCDMA情況下才能從“設(shè)置”->“無線和網(wǎng)絡(luò)”->“移動網(wǎng)絡(luò)”->“接入點名稱”中選擇不同的apn帳號進行撥號連接，而CDMA/EVDO則沒有這個功能。最近看了一下代碼，簡單實現(xiàn)了這個功能。

1、默認的CDMA/EVDO里面連apn列表都不顯示，要先把這個挖出來。
修改packages/apps/Phone/res/xml/cdma_options.xml
添加如下內(nèi)容

復(fù)制代碼代碼如下:

 
<PreferenceScreen 
android:key="button_apn_key" 
android:title="@string/apn_settings" 
android:persistent="false"> 
<intent android:action="android.intent.action.MAIN" 
android:targetPackage="com.android.settings" 
android:targetClass="com.android.settings.ApnSettings" /> 
</PreferenceScreen> 

還有development/data/etc/apns-conf.xml的version值改為原來的加1，原因代碼里面找。
2、修改frameworks/base/telephony/java/com/android/internal/telephony/cdma/cdmadataconnectiontracker.java的setupData函數(shù)

復(fù)制代碼代碼如下:

 
private boolean setupData(String reason) { 
CdmaDataConnection conn = findFreeDataConnection(); 
if (conn == null) { 
if (DBG) log("setupData: No free CdmaDataConnection found!"); 
return false; 
} 
mActiveDataConnection = conn; 
String[] types; 
if (mRequestedApnType.equals(Phone.APN_TYPE_DUN)) { 
types = new String[1]; 
types[0] = Phone.APN_TYPE_DUN; 
} else { 
types = mDefaultApnTypes; 
} 
//mActiveApn = new ApnSetting(0, "", "", "", "", "", "", "", "", "", "", 
// 0, types, "IP", "IP"); 
Uri PREFERRED_APN_URI = Uri.parse("content://telephony/carriers/preferapn"); 
ContentResolver cResolver = phone.getContext().getContentResolver(); 
Cursor cr = cResolver.query(PREFERRED_APN_URI, null, null, null, null); 
cr.moveToFirst(); 
String user = cr.getString(cr.getColumnIndex("user")); 
String pass = cr.getString(cr.getColumnIndex("password")); 
String apn = cr.getString(cr.getColumnIndex("apn")); 
Log.e(LOG_TAG, "get apn : apn=" + apn + ", user=" + user + ", password=" + pass); 
mActiveApn = new ApnSetting(0, "", "", apn, "", "", "", "", "", user, pass, 
, types, "IP", "IP"); 
Message msg = obtainMessage(); 
msg.what = EVENT_DATA_SETUP_COMPLETE; 
msg.obj = reason; 
conn.connect(msg, mActiveApn); 
setState(State.INITING); 
phone.notifyDataConnection(reason); 
return true; 
} 

3、修改frameworks/base/telephony/java/com/android/internal/telephony/cdma/cdmadataconnection.java的onConnect函數(shù)：

復(fù)制代碼代碼如下:

 
phone.mCM.setupDataCall( 
Integer.toString(RILConstants.SETUP_DATA_TECH_CDMA), 
Integer.toString(dataProfile), 
//null, null, null,　　//原來傳進撥號的參數(shù)都是空的?。?！ 
cp.apn.apn, cp.apn.user, cp.apn.password, 
Integer.toString(RILConstants.SETUP_DATA_AUTH_PAP_CHAP), 
RILConstants.SETUP_DATA_PROTOCOL_IP, msg); 

4、修改frameworks/base/telephony/java/com/android/internal/telephony/gsm/ApnSetting.java中對ApnSetting的定義，將其成員類型全部設(shè)為public
