在此选项中, 我手中的平台,目前是没有任何选项显示的.

代码:

packages/apps/Settings/src/com/android/settings/ApnSettings.java

//以下代码用于构建一个列表, 从数据库中读取数据并填充到表中.

//注意下面的代码有一些过滤条件

private void fillList() {

String where = "numeric=\""

+ android.os.SystemProperties.get(TelephonyProperties.PROPERTY_ICC_OPERATOR_NUMERIC, "")

+ "\"";

String operatorDongle = SystemProperties.get("gsm.dongle.operator");

Log.d(TAG,"fillList:operatorDongle:"+operatorDongle);

if(operatorDongle != null) {

if(!operatorDongle.equals("llll") && false)

where = "numeric=\""+operatorDongle+"\"";

}

//从数据库获取, 下面代码会说明数据库是如何创建及始化的.

Cursor cursor = getContentResolver().query(Telephony.Carriers.CONTENT_URI, new String[] {

"_id", "name", "apn", "type"}, null, null,

Telephony.Carriers.DEFAULT_SORT_ORDER);

PreferenceGroup apnList = (PreferenceGroup) findPreference("apn_list");

apnList.removeAll();

ArrayList mmsApnList = new ArrayList();

mSelectedKey = getSelectedApnKey();

cursor.moveToFirst();

while (!cursor.isAfterLast()) {

String name = cursor.getString(NAME_INDEX);

String apn = cursor.getString(APN_INDEX);

String key = cursor.getString(ID_INDEX);

String type = cursor.getString(TYPES_INDEX);

ApnPreference pref = new ApnPreference(this);

pref.setKey(key);

pref.setTitle(name);

pref.setSummary(apn);

pref.setPersistent(false);

pref.setOnPreferenceChangeListener(this);

boolean selectable = ((type == null) || !type.equals("mms"));

pref.setSelectable(selectable);

if (selectable) {

if ((mSelectedKey != null) && mSelectedKey.equals(key)) {

pref.setChecked();

}

apnList.addPreference(pref);

} else {

mmsApnList.add(pref);

}

cursor.moveToNext();

}

cursor.close();

for (Preference preference : mmsApnList) {

apnList.addPreference(preference);

}

}

数据库创建:

packages/providers/TelephonyProvider/src/com/android/providers/telephony/TelephonyProvider.java

private static class DatabaseHelper extends SQLiteOpenHelper {

// Context to access resources with

private Context mContext;

/**

* DatabaseHelper helper class for loading apns into a database.

*

* @param context of the user.

*/

public DatabaseHelper(Context context) {

super(context, DATABASE_NAME, null, getVersion(context));

mContext = context;

}

private static int getVersion(Context context) {

// Get the database version, combining a static schema version and the XML version

Resources r = context.getResources();

XmlResourceParser parser = r.getXml(com.android.internal.R.xml.apns);

try {

XmlUtils.beginDocument(parser, "apns");

int publicversion = Integer.parseInt(parser.getAttributeValue(null, "version"));

return DATABASE_VERSION | publicversion;

} catch (Exception e) {

Log.e(TAG, "Can't get version of APN database", e);

return DATABASE_VERSION;

} finally {

parser.close();

}

}

@Override

public void onCreate(SQLiteDatabase db) {

// Set up the database schema

db.execSQL("CREATE TABLE " + CARRIERS_TABLE +

"(_id INTEGER PRIMARY KEY," +

"name TEXT," +

"numeric TEXT," +

"mcc TEXT," +

initDatabase(db);//创建后,初始数据

}

private void initDatabase(SQLiteDatabase db) {

// Read internal APNS data

Resources r = mContext.getResources();

XmlResourceParser parser = r.getXml(com.android.internal.R.xml.apns);//从frameworks/base/core/res/中获取XML并添加到数据库中.

int publicversion = -1;

try {

XmlUtils.beginDocument(parser, "apns");

publicversion = Integer.parseInt(parser.getAttributeValue(null, "version"));

loadApns(db, parser);

} catch (Exception e) {

Log.e(TAG, "Got exception while loading APN database.", e);

} finally {

parser.close();

}

// Read external APNS data (partner-provided)

XmlPullParser confparser = null;

// Environment.getRootDirectory() is a fancy way of saying ANDROID_ROOT or "/system".

File confFile = new File(Environment.getRootDirectory(), PARTNER_APNS_PATH);//从/etc/apns-conf.xml中获取并添加到数据库中.

FileReader confreader = null;

try {

confreader = new FileReader(confFile);

confparser = Xml.newPullParser();

confparser.setInput(confreader);

XmlUtils.beginDocument(confparser, "apns");

// Sanity check. Force internal version and confidential versions to agree

int confversion = Integer.parseInt(confparser.getAttributeValue(null, "version"));

if (publicversion != confversion) {

throw new IllegalStateException("Internal APNS file version doesn't match "

+ confFile.getAbsolutePath());

}

loadApns(db, confparser);

} catch (FileNotFoundException e) {

// It's ok if the file isn't found. It means there isn't a confidential file

// Log.e(TAG, "File not found: '" + confFile.getAbsolutePath() + "'");

} catch (Exception e) {

Log.e(TAG, "Exception while parsing '" + confFile.getAbsolutePath() + "'", e);

} finally {

try { if (confreader != null) confreader.close(); } catch (IOException e) { }

}

}

所以, 一般默认的APN有两个地方可添加:

1. frameworks/base/core/res/res/xml/apns.xml

2. RK平台中,采用此路径:

device/rockchip/common/phone/etc/apns-full-conf.xml

XML的内容如下:
