AccessPoint.java添加CMCC等三个AP，有较多修改
其中的
import workInfo.DetailedState;
import .wifi.ScanResult;
import .wifi.WifiConfiguration;
import .wifi.WifiConfiguration.KeyMgmt;
import .wifi.WifiInfo;
import .wifi.WifiManager;
首先要看的，这里和好多的net/wifi相关的在framework中的内容了。

class AccessPoint extends Preference {
public int compareTo(Preference preference)
public boolean equals(Object other) {
if (!(other instanceof AccessPoint)) return false;
return (pareTo((AccessPoint) other) == 0);
}
public String getSecurityString(boolean concise) {
concise -- ***.short***
public int hashCode() { ---no used.
static final String CARRIER_SSID = "CMCC";
static final String CARRIER_EDU_SSID = "CMCC-EDU";
static final String CARRIER_AUTO_SSID = "CMCC-AUTO";
private WifiConfiguration mConfig;
/* package */ScanResult mScanResult; --- 这个在framework中的net/wifi中详细的定义了。

这里有链接的状态了。

public enum DetailedState {
/** Ready to start data connection setup. */
IDLE,
/** Searching for an available access point. */
SCANNING,
/** Currently setting up data connection. */
CONNECTING,
/** Network link established, performing authentication. */
AUTHENTICATING,
/** Awaiting response from DHCP server in order to assign IP address information. */
OBTAINING_IPADDR,
/** IP traffic should be available. */
CONNECTED,
/** IP traffic is suspended */
SUSPENDED,
/** Currently tearing down data connection. */
DISCONNECTING,
/** IP traffic not available. */
DISCONNECTED,
/** Attempt to connect failed. */
FAILED,
/** Access to this network is blocked. */
BLOCKED,
/** Link has poor connectivity. */
VERIFYING_POOR_LINK,
/** Checking if network is a captive portal */
CAPTIVE_PORTAL_CHECK
}
AdvancedWifiSettings.java—menu
public class AdvancedWifiSettings extends SettingsPreferenceFragment private void updateSleepPolicySummary(Preference sleepPolicyPref, String value) {
这里干了什么，不是明白，什么的协议！！！
public static final int wifi_sleep_policy_entries=0x7f070022;
/** Wi-Fi settings. Presented as a list dialog to the user to choose the Wi-Fi sleep policy. Used when
the device is Wi-Fi-only. [CHAR LIMIT=30]
*/
public static final int
wifi_sleep_policy_entries_wifi_only=0x7f070023;
private void updateFrequencyBandSummary(Preference frequencyBandPref, int index) {
String[] summaries =
getResources().getStringArray(R.array.wifi_frequency_band_entries);
frequencyBandPref.setSummary(summaries[index]);
}
HostAp
WifiApDialog.java 对hostAp 的WifiConfiguration配置Diag
import .wifi.WifiConfiguration;
import .wifi.WifiConfiguration.AuthAlgorithm;
import .wifi.WifiConfiguration.KeyMgmt;
public WifiConfiguration getConfig() {
WifiConfiguration config = new WifiConfiguration();
WifiApEnabler.java开关hostAp，不是wifi
应该是一个简单的类这个同这些内容
import .ConnectivityManager;
import workInfo;
import .wifi.SupplicantState;
import .wifi.WifiConfiguration;
import .wifi.WifiInfo;
import .wifi.WifiManager;
public class WifiApEnabler {
private final BroadcastReceiver mReceiver = new BroadcastReceiver() { @Override
public void onReceive(Context context, Intent intent) {
这个就是一个接受。

这个可能就是hostAp的开关吧，disable和enable相关的内容都在这里吧！！！！
public WifiApEnabler(Context context, CheckBoxPreference checkBox) { mContext = context;
mCheckBox = checkBox;
mOriginalSummary = checkBox.getSummary();
checkBox.setPersistent(false);
mWaitForWifiStateChange = true;
mWifiManager = (WifiManager)
context.getSystemService(Context.WIFI_SERVICE);
mCm =
(ConnectivityManager)mContext.getSystemService(Context.CONNECTIVITY_SERVICE);
mWifiRegexs = mCm.getTetherableWifiRegexs();
mIntentFilter = new
IntentFilter(WifiManager.WIFI_AP_STATE_CHANGED_ACTION);
mIntentFilter.addAction(ConnectivityManager.ACTION_TETHER_STATE_CHANGED);
mIntentFilter.addAction(Intent.ACTION_AIRPLANE_MODE_CHANGED);
mIntentFilter.addAction(WifiManager.WIFI_STATE_CHANGED_ACTION);
}
主要接口就是两个
public void setSoftapEnabled(boolean enable) {
public void updateConfigSummary(WifiConfiguration wifiConfig) {
TetherSettings.java
其实的使用在TetherSettings.java – tether范围的意思—应该翻译成共享，分为USB、wifi 和bt三种共享方式。

public boolean onPreferenceChange(Preference preference, Object value) { boolean enable = (Boolean) value;
if (enable) {
startProvisioningIfNecessary(WIFI_TETHERING);
} else {
mWifiApEnabler.setSoftapEnabled(false);
}
return false;
}
Wifi测试工程模式下的三个菜单项input *#*#4636#*#*：
WifiAPITest.java测试1---API
/**
* Provide an interface for testing out the Wifi API
*/
public class WifiAPITest extends PreferenceActivity implements
Preference.OnPreferenceClickListener {
这个100多行的程序的，就是一个perferenceActivity,很贴切的地方啊！
WifiStatusTest.java测试2---状态
整个代码很简单的，先定义一个BroadcReceiver
然后得到
mWifiManager = (WifiManager) getSystemService(WIFI_SERVICE);
mWifiStateFilter = new
IntentFilter(WifiManager.WIFI_STATE_CHANGED_ACTION);
mWifiStateFilter.addAction(WifiManager.RSSI_CHANGED_ACTION);
mWifiStateFilter.addAction(WifiManager.WIFI_STATE_CHANGED_ACTION); registerReceiver(mWifiStateReceiver, mWifiStateFilter);
然后，注册一些intent。

第四，定义两个button：
一个refresh
updateButton = (Button) findViewById(R.id.update);
updateButton.setOnClickListener(updateButtonHandler);
另一个ping
pingTestButton = (Button) findViewById(R.id.ping_test);
pingTestButton.setOnClickListener(mPingButtonHandler);
最后就是简单的两个ping和http clinet测试，整个十分的简单，没有任何逻辑。

WifiConfigInfo.java测试3---config显示
无修改
1. Turn off Wi-Fi
2. Open the dialer and input *#*#4636#*#*
3. Navigate to Wi-Fi information -> Wi-Fi config and observe "Unfortunately,
/**
* Configuration details saved by the user on the WifiSettings screen */
public class WifiConfigInfo extends Activity {
WifiConfigController\ WifiConfigUiBase –三个不是工程模式
WifiConfigController.java
文件的内容及其的复杂啊，但是public的内容很少，why
/**
* The class for allowing UIs like {@link WifiDialog} and {@link WifiConfigUiBase} to
* share the logic for controlling buttons, text fields, etc.
*/
public class WifiConfigController implements TextWatcher,
AdapterView.OnItemSelectedListener, OnCheckedChangeListener {
WifiConfigUiBase.java
无修改
/**
* Foundation interface glues between Activities and UIs like
* {@link WifiDialog} or {@link WifiConfigUiForSetupWizardXL}.
*/
public interface WifiConfigUiBase {
WifiConfigUiForSetupWizardXL.java
无修改，
/**
* Shows simplified UI for configuring a wifi network. Used only in SetupWizard for XLarge
* screen.
*/
public class WifiConfigUiForSetupWizardXL implements WifiConfigUiBase, OnFocusChangeListener {
private static final String TAG = "SetupWizard";
WifiDialog.java
无修改
class WifiDialog extends AlertDialog implements WifiConfigUiBase {
WifiInfo.java
文件无内容几乎。

/**
* Wifi information menu item on the diagnostic screen
*/
public class WifiInfo extends PreferenceActivity {
WifiPickerActivity.java
无修改
public class WifiPickerActivity extends PreferenceActivity implements ButtonBarHandler {
发出一群intent
/**
* The ping functions have been borrowed from Radio diagnostic app to
* enable quick access on the wifi status screen
*/
private final void pingIpAddr() {
的确这个是从radio中看到的，两处都有这个定义，这个简单的，来ping ipaddress、ping host和 private void httpClientTest() {
这个很简单的代码。

private void httpClientTest() {
HttpClient client = new DefaultHttpClient();
try {
// TODO: Hardcoded for now, make it UI configurable
HttpGet request = new HttpGet(""); HttpResponse response = client.execute(request);
if (response.getStatusLine().getStatusCode() == 200) {
mHttpClientTestResult = "Pass";
} else {
mHttpClientTestResult = "Fail: Code: " +
String.valueOf(response);
}
request.abort();
} catch (IOException e) {
mHttpClientTestResult = "Fail: IOException";
}
}
/**
* Show the current status details of Wifi related fields
*/
public class WifiStatusTest extends Activity {
不明这个修改，为什么呢？

Settings: Invalid wifi/bluetooth switch in airplane mode
- wifi/bluetooth switch will be invalid in airplane mode
WifiScanModeActivity.java – menu后scan吗？
单单一个对话框吗？
/**
* This activity requests users permission to allow scanning even when Wi-Fi is turned off
*/
public class WifiScanModeActivity extends Activity {
就是一个强制的搜索吗？
private void doPositiveClick() {
Settings.Global.putInt(getContentResolver(),
Settings.Global.WIFI_SCAN_ALWAYS_AVAILABLE, 1);
Strings.xml (v:\.3.7.1\packages\apps\settings\res\values): <string
name="wifi_scan_always_available">Scanning always available</string>
WifiSettings.java
/**
* Two types of UI are provided here.
*
* The first is for "usual Settings", appearing as any other Setup fragment. *
* The second is for Setup Wizard, with a simplified interface that hides the action bar
* and menus.
*/
public class WifiSettings extends RestrictedSettingsFragment
implements DialogInterface.OnClickListener {
新添加的WifiPrioritySettings.java 为了三种模式
而且改动了好多的文件地方
summary.java
这个summary怎么没有用到奇怪啊！！！
Android Wireless Architecture –3 part
Android Wireless Architecture can be divided in three part
1 Java Framework (WiFiManager,WifiMonitor etc..),
2 HAL(wifi.c, wpa_supplicant) and
3 kernel space modules (Wireless stack, driver).
Following figure show the Android Wifi Architecture. Java Framework communicate with wpa_supplicant using native interface (wifi.c) . wpa_supplicant uses wireless extension to control wifi driver.
Application Framework code for WifiManager, WifiMonitor , WifiConfiguration are in base/wifi/java/android/net/wifi folder.
Jni code written in “android_net_wifi_Wifi.cpp” located in “frameworks/base/core/jni” folder. Which communicate with HAL layer.
HAL layer code is written in wifi.c(hardware/libhardware_legacy/wifi/). Code in wifi.c file communicate with wpa_supplicant over control interface.
Above shown architecture applies to the wireless drivers which uses wireless extension to communicate with driver. With the implementation of nl80211/cfg80211 many wireless drivers in main line kernel support nl80211 interface instead of wireless extension.
从call stack上看关系
