android2.3.5 CDMA and EVDO dial APN solution

In google's android2.3, you can only "set" - from GSM/WCDMA > "Wireless and networking" - > "Mobile network" - > Select a different apn account in "access point name" for dial-up connections, while CDMA/EVDO does not. Recently, I took a look at the code and simply implemented this function.

1. The CDMA/EVDO of by default does not even show the apn list.
Modify packages apps/Phone res/xml/cdma_options xml
Add the following

 
<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> 

And development/data/etc/apns - conf. xml version value instead of the original plus 1, find a reason code.
2, modified frameworks base/telephony/java/com/android/internal/telephony/cdma/cdmadataconnectiontracker java setupData function

 
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, modify frameworks/base/telephony/java/com/android/internal telephony/cdma/cdmadataconnection java onConnect function:

 
phone.mCM.setupDataCall( 
Integer.toString(RILConstants.SETUP_DATA_TECH_CDMA), 
Integer.toString(dataProfile), 
//null, null, null,　　// The original parameters are empty!!  
cp.apn.apn, cp.apn.user, cp.apn.password, 
Integer.toString(RILConstants.SETUP_DATA_AUTH_PAP_CHAP), 
RILConstants.SETUP_DATA_PROTOCOL_IP, msg); 

4, modify frameworks/base/telephony/java/com/android/internal/telephony/gsm/ApnSetting. The definition of ApnSetting java, its entire member type set to public
