首先弄懂怎么设置adb wifi无线调试的功能，如下所示。
1. 手机端开启adb tcp连接端口
但是每次这样的去设置很繁琐，所以直接在设置中做一个开关就把手机端的设置做好，如下所示：一、打开开关，并连接Wifi
二、打开开关，没有连接Wifi
三、未打开开关
这样就可以直接进行adb wifi调试了，手机端就不用每次都先用USB调试去设置修改的属性，才能激活adb wifi调试。
======================================================================================================
下面来具体说说实现的思路：第一步：在【设置】-->【开发者选项】中做一个类似于【USB调试】的开关【Wifi调试】第二步：【Wifi调试】开关打开就激活监听5555端口，用来进行adb wifi调试，【Wifi调试】开关关闭就不监听5555端口，这样就不能进行adb wifi调试第三步：在第二步中打开关闭【Wifi调试】开关的时候，调用相应的接口进行设置第四步：将第三步中要调用的接口写好
1、先在布局中加入该开关
首先找到布局文件，packages/apps/Settings/res/xml/development_prefs.xml，找到【USB调试】开关的相应代码，然后再里面加一个【Wifi调试】开关，代码如下： <SwitchPreference
android:key="enable_adb"
android:title="@string/enable_adb"
android:summary="@string/enable_adb_summary"/>
<!-- added by ouyang start -->
<SwitchPreference
android:key="enable_wifi_adb"
android:title="@string/enable_wifi_adb"
android:summary="@string/enable_wifi_adb_summary"/>
<!-- added by ouyang end -->上面代码中，第一个代码是【USB调试】开关的代码，第二个是我加的【Wifi调试】开关的代码，然后为什么的字符串做相应的国际化操作，代码如下：packages/apps/Settings/res/values-zh-rCN/strings.xml 中加入：<!-- added by ouyang start 2015-12-17 -->
<string name="enable_wifi_adb">Wifi调试</string>
<string name="enable_wifi_adb_openwifi">Wifi没连接，请连接wifi</string>
<string name="enable_wifi_adb_summary">连接Wifi后启用调试模式</string>
<string name="enable_wifi_adb_connected_summary">Wifi调试已打开,在电脑端你可以输入以下命令进行调试:\n
adb connect <xliff:g id="ip_address">%1$s</xliff:g>:5555</string>
<!-- added by ouyang end 2015-12-17 -->
packages/apps/Settings/res/values/strings.xml 中加入： <!-- added by ouyang start 2015-12-17 -->
<string name="enable_wifi_adb">Wifi debugging</string>
<string name="enable_wifi_adb_openwifi">Wifi is not connected,please turn wifi on and connect it</string>
<string name="enable_wifi_adb_summary">Debug mode when Wifi is connected</string>
<string name="enable_wifi_adb_connected_summary">adb wifi is on,from your computer run:\n
adb connect <xliff:g id="ip_address">%1$s</xliff:g>:5555</string>
<!-- added by ouyang end 2015-12-17 -->
2、在packages/apps/Settings/src/com/android/settings/DevelopmentSettings.java文件中，对刚才加入的【Wifi调试】开关进行相关的逻辑处理。首先先定义开关的几个变量，如下： //add by ouyang 2015-12-17 start
private static final String ENABLE_WIFI_ADB = "enable_wifi_adb";
private static final String ADB_WIFI_ENABLED_KEY = "ADB_WIFI_ENABLED";
private static SwitchPreference mEnableWifiAdb;
//add by ouyang 2015-12-17 end然后再onCreate()方法中初始化【Wifi调试】开关，如下： mEnableAdb = findAndInitSwitchPref(ENABLE_ADB);
//add by ouyang 2015-12-17
mEnableWifiAdb = findAndInitSwitchPref(ENABLE_WIFI_ADB);然后在onPreferenceTreeClick(PreferenceScreen preferenceScreen, Preference preference)方法中对【Wifi调试】开关的打开和关闭操作做逻辑处理。 if (preference == mEnableAdb) {
if (mEnableAdb.isChecked()) {
mDialogClicked = false;
if (mAdbDialog != null) dismissDialogs();
mAdbDialog = new AlertDialog.Builder(getActivity()).setMessage(
getActivity().getResources().getString(R.string.adb_warning_message))
.setTitle(R.string.adb_warning_title)
.setPositiveButton(android.R.string.yes, this)
.setNegativeButton(android.R.string.no, this)
.show();
mAdbDialog.setOnDismissListener(this);
} else {
Settings.Global.putInt(getActivity().getContentResolver(),
Settings.Global.ADB_ENABLED, 0);
mVerifyAppsOverUsb.setEnabled(false);
mVerifyAppsOverUsb.setChecked(false);
/// M: ALPS01256802, The "Developer options" status is opened.
onPreferenceTreeClick(null, mVerifyAppsOverUsb);
updateBugreportOptions();
}
}
//add by ouyang 2015-12-17 start
else if (preference == mEnableWifiAdb) {
if (mEnableWifiAdb.isChecked()) {
Settings.Global.putInt(getActivity().getContentResolver(),ADB_WIFI_ENABLED_KEY, 1);
android.os.SystemProperties.set("sys.connect.adb.wifi","1");
WifiManager wifiManager = (WifiManager)getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
int ipAddress = wifiInfo.getIpAddress();
String ipAddressString = (ipAddress & 0xFF ) + "." +((ipAddress >> 8 ) & 0xFF) + "." +
((ipAddress >> 16 ) & 0xFF) + "." +( ipAddress >> 24 & 0xFF) ;
Log.i(TAG, "ipAddress="+ipAddress);
Log.i(TAG, "ipAddressString="+ipAddressString);
if ("0.0.0.0".equals(ipAddressString)) {
mEnableWifiAdb.setSummary(getResources().getString(R.string.enable_wifi_adb_openwifi));
}else{
mEnableWifiAdb.setSummary(getResources().
getString(R.string.enable_wifi_adb_connected_summary,ipAddressString));
}
} else {
Settings.Global.putInt(getActivity().getContentResolver(),ADB_WIFI_ENABLED_KEY, 0);
android.os.SystemProperties.set("sys.connect.adb.wifi","0");
mEnableWifiAdb.setSummary(getResources().getString(R.string.enable_wifi_adb_summary));
}
}
//add by ouyang 2015-12-17 end
上面的代码主要是， 当【Wifi调试】开关打开的时候，保存一个原来表示该【Wifi调试】开关打开关闭的状态的值为1，然后调用接口android.os.SystemProperties.set("sys.connect.adb.wifi","1");如果wifi这个时候打开就显示相应的adb wifi命令，如ip地址为192.168.107.201的时候就显示，"Wifi调试已打开,在电脑端你可以输入以下命令进行调试:adb connect 192.168.107.201:5555"；如果wifi为打开，就提示“Wifi没连接，请连接wifi” 当【Wifi调试】开关关闭的时候，保存一个原来表示该【Wifi调试】开关打开关闭的状态的值为0，然后调用接口android.os.SystemProperties.set("sys.connect.adb.wifi","0");
ADB_WIFI_ENABLED_KEY这个状态值，在进入该Activity的时候，如果上次打开了【Wifi调试】开关，那么下次进来的时候就要显示【Wifi调试】开关是打开状态，否则是关闭状态。下面说说ADB_WIFI_ENABLED_KEY这个状态值的相关代码，如下：在onResume()方法中，加入下面代码： //add by ouyang 2015-12-17 start
IntentFilter filter = new IntentFilter();
filter.addAction(WifiManager.NETWORK_STATE_CHANGED_ACTION);
filter.addAction(WifiManager.WIFI_STATE_CHANGED_ACTION);
filter.addAction(ConnectivityManager.CONNECTIVITY_ACTION);
getActivity().registerReceiver(wifiBroadcastReceiver, filter);
boolean isAdbWifiChecked = Settings.Global.getInt(getActivity().getContentResolver(),ADB_WIFI_ENABLED_KEY, 0) != 0;
mEnableWifiAdb.setChecked(isAdbWifiChecked);
Log.i(TAG, "isAdbWifiChecked:" + isAdbWifiChecked);
//add by ouyang 2015-12-17 end 代码的意思是，进入该Activity就动态的注册一个广播，用来监听Wifi的状态改变的，然后来动态的显示Android手机获取的IP地址。然后根据ADB_WIFI_ENABLED_KEY这个状态值来显示【Wifi调试】开关的打开关闭状态。
在updateAllOptions()方法中，也要去做下处理，代码如下：/// M: CR ALPS00244115. Lock and unlock screen, the "USB debugging" is unchecked.
boolean isChecked = (mAdbDialog != null && mAdbDialog.isShowing()) ? true :
(Settings.Global.getInt(cr, Settings.Global.ADB_ENABLED, 0) != 0);
updateSwitchPreference(mEnableAdb, isChecked);
//add by ouyang 2015-12-17 start
boolean isAdbWifiChecked = Settings.Global.getInt(cr,ADB_WIFI_ENABLED_KEY, 0) != 0;
updateSwitchPreference(mEnableWifiAdb, isAdbWifiChecked);
//add by ouyang 2015-12-17 end
/// M: update usb preference again
mExt.customUSBPreference(mEnableAdb);
//add by ouyang 2015-12-17
mExt.customUSBPreference(mEnableWifiAdb);
下面来说说上面动态注册的广播，代码如下：BroadcastReceiver wifiBroadcastReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String TAG = "wifiBroadcastReceiver";
boolean isAdbWifiChecked = mEnableWifiAdb.isChecked();
ConnectivityManager connectivityManager = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo net = connectivityManager.getActiveNetworkInfo();
if (net == null) {
Log.i(TAG, "No net type");
if (isAdbWifiChecked) {
mEnableWifiAdb.setSummary(getResources()
.getString(R.string.enable_wifi_adb_openwifi));
}
} else {
Log.i(TAG, "Net Type:" + net.getTypeName());
}
State wifi = connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI).getState();
if (wifi == State.CONNECTED || wifi == State.CONNECTING) {
Log.i(TAG, "wifi connected");
WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
int ipAddress = wifiInfo.getIpAddress();
String ipAddressString = (ipAddress & 0xFF) + "." + ((ipAddress >> 8) & 0xFF) + "."
+ ((ipAddress >> 16) & 0xFF) + "." + (ipAddress >> 24 & 0xFF);
if (isAdbWifiChecked) {
mEnableWifiAdb.setSummary(
getResources().getString(
R.string.enable_wifi_adb_connected_summary, ipAddressString));
}
Log.i(TAG, getResources().getString(
R.string.enable_wifi_adb_connected_summary, ipAddressString));
} else if (wifi == State.DISCONNECTED || wifi == State.DISCONNECTING) {
Log.i(TAG, "wifi disconnected");
if (isAdbWifiChecked) {
mEnableWifiAdb.setSummary(
getResources().getString(R.string.enable_wifi_adb_openwifi));
}
Log.i(TAG, getResources().getString(
R.string.enable_wifi_adb_connected_summary));
}
}
};
上面的代码主要是当【Wifi调试】开关打开的时候，来用动态表示Android手机的Wifi连接状态，如果wifi未连接，就提示“Wifi没连接，请连接wifi”，如果Wifi连接了，就动态的将从DHCP服务器获取的IP地址显示出来，如ip地址为192.168.107.201的时候就显示，"Wifi调试已打开,在电脑端你可以输入以下命令进行调试:adb connect 192.168.107.201:5555"======================================================================================================
好吧，在packages/apps/Settings/，即Settings APP层面的代码写完了，下面来说说调用的两个接口怎么实现。android.os.SystemProperties.set("sys.connect.adb.wifi", "1");android.os.SystemProperties.set("sys.connect.adb.wifi", "0");
首先找到frameworks/base/core/java/android/os/SystemProperties.java文件，找到set(String key, String val)方法，代码如下，发现调用了native_set(key, val)方法。 /**
* Set the value for the given key.
* @throws IllegalArgumentException if the key exceeds 32 characters
* @throws IllegalArgumentException if the value exceeds 92 characters
*/
public static void set(String key, String val) {
if (key.length() > PROP_NAME_MAX) {
throw new IllegalArgumentException("key.length > " + PROP_NAME_MAX);
}
if (val != null && val.length() > PROP_VALUE_MAX) {
throw new IllegalArgumentException("val.length > " +
PROP_VALUE_MAX);
}
native_set(key, val);
}native_set(key, val)方法定义如下：private static native void native_set(String key, String def);
该接口类在初始化运行环境中注册对应的cpp接口android_os_SystemProperties.cpp，实际操作通过JNI调用的是cpp文件对应的接口：frameworks/base/core/jni/AndroidRuntime.cpp
namespace android {
extern int register_android_os_SystemProperties(JNIEnv *env);
}
frameworks/base/core/jni/android_os_SystemProperties.cpp
static void SystemProperties_set(JNIEnv *env, jobject clazz,
jstring keyJ, jstring valJ)
{
int err;
const char* key;
const char* val;
if (keyJ == NULL) {
jniThrowNullPointerException(env, "key must not be null.");
return ;
}
key = env->GetStringUTFChars(keyJ, NULL);
if (valJ == NULL) {
val = ""; /* NULL pointer not allowed here */
} else {
val = env->GetStringUTFChars(valJ, NULL);
}
err = property_set(key, val);
env->ReleaseStringUTFChars(keyJ, key);
if (valJ != NULL) {
env->ReleaseStringUTFChars(valJ, val);
}
if (err < 0) {
ALOGE("setproperty key=%s value=%s err=%d\n", key, val, err);
jniThrowException(env, "java/lang/RuntimeException",
"failed to set system property");
}
}
好了，关于该android.os.SystemProperties.set()方法的分析，可以参考http://blog.csdn.net/ameyume/article/details/8056492http://www.blogjava.net/anymobile/articles/301989.html
下面直接写下面两个接口的实现
android.os.SystemProperties.set("sys.connect.adb.wifi", "1");android.os.SystemProperties.set("sys.connect.adb.wifi", "0");
在device/lentek/lentk6735_66t_l1/E580/init.rc文件中加入下面的代码，其中E580是项目的名称。#added by ouyang start connect adb with wifi
on property:sys.connect.adb.wifi=1
setprop service.adb.tcp.port 5555
stop adbd
start adbd
on property:sys.connect.adb.wifi=0
setprop service.adb.tcp.port ""
stop adbd
start adbd
#added by ouyang end connect adb with wifi上面代码就是当调用android.os.SystemProperties.set("sys.connect.adb.wifi", "1");和sys.connect.adb.wifiandroid.os.SystemProperties.set("sys.connect.adb.wifi", "0");接口的时候的具体实现，即"sys.connect.adb.wifi"属性设置为1的时候，监听5555端口， "sys.connect.adb.wifi"属性设置为0的时候，不监听任何端口
====================================================================================好了，下面来再一次测一测该功能怎么样，重新打开wifi,重新打开【Wifi调试】开关，显示如下：
可以看出来，此时Android手机的IP地址是192.168.107.168，因此下面在PC端测试看是否可以用adb wifi无线调试，使用命令adb connect 192.168.107.168连接,adb disconnect 192.168.107.168断开连接，如下图所示：
C:\Documents and Settings\Administrator>adb connect 192.168.107.168

发现可以正常的进行adb wifi 无线调试了。将【Wifi调试】开关【Wifi调试】开关关闭，再去连接的话，就会无法连接了。如下所示：
C:\Documents and Settings\Administrator>adb connect 192.168.107.168
unable to connect to 192.168.107.168:5555

1. 手机端开启adb tcp连接端口
:/$setprop service.adb.tcp.port 5555 :/$stop adbd :/$start adbd其中setprop是用来设置系统属性的，这里不需要root权限，su即可。可通过adb shell设置，亦可通过手机上安装的Android terminal设置。2. 电脑端的设置和使用连接adb，其中phone_ipaddress和portnumber是指手机的ip和前面设置的监听端口号（如5555）
adb connect phone_ipaddress:portnumber直接adb shell或adb -s 设备shell连接设备如若要断开则如下：
adb disconnect phone_ipaddress:port
但是每次这样的去设置很繁琐，所以直接在设置中做一个开关就把手机端的设置做好，如下所示：一、打开开关，并连接Wifi
二、打开开关，没有连接Wifi
三、未打开开关
这样就可以直接进行adb wifi调试了，手机端就不用每次都先用USB调试去设置修改的属性，才能激活adb wifi调试。
======================================================================================================
下面来具体说说实现的思路：第一步：在【设置】-->【开发者选项】中做一个类似于【USB调试】的开关【Wifi调试】第二步：【Wifi调试】开关打开就激活监听5555端口，用来进行adb wifi调试，【Wifi调试】开关关闭就不监听5555端口，这样就不能进行adb wifi调试第三步：在第二步中打开关闭【Wifi调试】开关的时候，调用相应的接口进行设置第四步：将第三步中要调用的接口写好
1、先在布局中加入该开关
首先找到布局文件，packages/apps/Settings/res/xml/development_prefs.xml，找到【USB调试】开关的相应代码，然后再里面加一个【Wifi调试】开关，代码如下： <SwitchPreference

<!-- added by ouyang start -->
<SwitchPreference

android:title="@string/enable_wifi_adb"
android:summary="@string/enable_wifi_adb_summary"/>
<!-- added by ouyang end -->上面代码中，第一个代码是【USB调试】开关的代码，第二个是我加的【Wifi调试】开关的代码，然后为什么的字符串做相应的国际化操作，代码如下：packages/apps/Settings/res/values-zh-rCN/strings.xml 中加入：<!-- added by ouyang start 2015-12-17 -->

<!-- added by ouyang end 2015-12-17 -->
2、在packages/apps/Settings/src/com/android/settings/DevelopmentSettings.java文件中，对刚才加入的【Wifi调试】开关进行相关的逻辑处理。首先先定义开关的几个变量，如下： //add by ouyang 2015-12-17 start
private static final String ENABLE_WIFI_ADB = "enable_wifi_adb";
private static final String ADB_WIFI_ENABLED_KEY = "ADB_WIFI_ENABLED";
private static SwitchPreference mEnableWifiAdb;
//add by ouyang 2015-12-17 end然后再onCreate()方法中初始化【Wifi调试】开关，如下： mEnableAdb = findAndInitSwitchPref(ENABLE_ADB);
//add by ouyang 2015-12-17
mEnableWifiAdb = findAndInitSwitchPref(ENABLE_WIFI_ADB);然后在onPreferenceTreeClick(PreferenceScreen preferenceScreen, Preference preference)方法中对【Wifi调试】开关的打开和关闭操作做逻辑处理。 if (preference == mEnableAdb) {
if (mEnableAdb.isChecked()) {
mDialogClicked = false;
if (mAdbDialog != null) dismissDialogs();
mAdbDialog = new AlertDialog.Builder(getActivity()).setMessage(
getActivity().getResources().getString(R.string.adb_warning_message))
.setTitle(R.string.adb_warning_title)
.setPositiveButton(android.R.string.yes, this)
.setNegativeButton(android.R.string.no, this)
.show();
mAdbDialog.setOnDismissListener(this);
} else {
Settings.Global.putInt(getActivity().getContentResolver(),
Settings.Global.ADB_ENABLED, 0);
mVerifyAppsOverUsb.setEnabled(false);
mVerifyAppsOverUsb.setChecked(false);
/// M: ALPS01256802, The "Developer options" status is opened.
onPreferenceTreeClick(null, mVerifyAppsOverUsb);
updateBugreportOptions();
}
}
//add by ouyang 2015-12-17 start
else if (preference == mEnableWifiAdb) {
if (mEnableWifiAdb.isChecked()) {
Settings.Global.putInt(getActivity().getContentResolver(),ADB_WIFI_ENABLED_KEY, 1);
android.os.SystemProperties.set("sys.connect.adb.wifi","1");
WifiManager wifiManager = (WifiManager)getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
int ipAddress = wifiInfo.getIpAddress();
String ipAddressString = (ipAddress & 0xFF ) + "." +((ipAddress >> 8 ) & 0xFF) + "." +
((ipAddress >> 16 ) & 0xFF) + "." +( ipAddress >> 24 & 0xFF) ;
Log.i(TAG, "ipAddress="+ipAddress);
Log.i(TAG, "ipAddressString="+ipAddressString);
if ("0.0.0.0".equals(ipAddressString)) {

}else{
mEnableWifiAdb.setSummary(getResources().
getString(R.string.enable_wifi_adb_connected_summary,ipAddressString));
}
} else {
Settings.Global.putInt(getActivity().getContentResolver(),ADB_WIFI_ENABLED_KEY, 0);

上面的代码主要是， 当【Wifi调试】开关打开的时候，保存一个原来表示该【Wifi调试】开关打开关闭的状态的值为1，然后调用接口android.os.SystemProperties.set("sys.connect.adb.wifi","1");如果wifi这个时候打开就显示相应的adb wifi命令，如ip地址为192.168.107.201的时候就显示，"Wifi调试已打开,在电脑端你可以输入以下命令进行调试:adb connect 192.168.107.201:5555"；如果wifi为打开，就提示“Wifi没连接，请连接wifi” 当【Wifi调试】开关关闭的时候，保存一个原来表示该【Wifi调试】开关打开关闭的状态的值为0，然后调用接口android.os.SystemProperties.set("sys.connect.adb.wifi","0");
ADB_WIFI_ENABLED_KEY这个状态值，在进入该Activity的时候，如果上次打开了【Wifi调试】开关，那么下次进来的时候就要显示【Wifi调试】开关是打开状态，否则是关闭状态。下面说说ADB_WIFI_ENABLED_KEY这个状态值的相关代码，如下：在onResume()方法中，加入下面代码： //add by ouyang 2015-12-17 start
IntentFilter filter = new IntentFilter();
filter.addAction(WifiManager.NETWORK_STATE_CHANGED_ACTION);
filter.addAction(WifiManager.WIFI_STATE_CHANGED_ACTION);
filter.addAction(ConnectivityManager.CONNECTIVITY_ACTION);
getActivity().registerReceiver(wifiBroadcastReceiver, filter);
boolean isAdbWifiChecked = Settings.Global.getInt(getActivity().getContentResolver(),ADB_WIFI_ENABLED_KEY, 0) != 0;
mEnableWifiAdb.setChecked(isAdbWifiChecked);
Log.i(TAG, "isAdbWifiChecked:" + isAdbWifiChecked);
//add by ouyang 2015-12-17 end 代码的意思是，进入该Activity就动态的注册一个广播，用来监听Wifi的状态改变的，然后来动态的显示Android手机获取的IP地址。然后根据ADB_WIFI_ENABLED_KEY这个状态值来显示【Wifi调试】开关的打开关闭状态。
在updateAllOptions()方法中，也要去做下处理，代码如下：/// M: CR ALPS00244115. Lock and unlock screen, the "USB debugging" is unchecked.
boolean isChecked = (mAdbDialog != null && mAdbDialog.isShowing()) ? true :
(Settings.Global.getInt(cr, Settings.Global.ADB_ENABLED, 0) != 0);
updateSwitchPreference(mEnableAdb, isChecked);
//add by ouyang 2015-12-17 start
boolean isAdbWifiChecked = Settings.Global.getInt(cr,ADB_WIFI_ENABLED_KEY, 0) != 0;
updateSwitchPreference(mEnableWifiAdb, isAdbWifiChecked);
//add by ouyang 2015-12-17 end
/// M: update usb preference again
mExt.customUSBPreference(mEnableAdb);
//add by ouyang 2015-12-17
mExt.customUSBPreference(mEnableWifiAdb);
下面来说说上面动态注册的广播，代码如下：BroadcastReceiver wifiBroadcastReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String TAG = "wifiBroadcastReceiver";
boolean isAdbWifiChecked = mEnableWifiAdb.isChecked();
ConnectivityManager connectivityManager = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo net = connectivityManager.getActiveNetworkInfo();
if (net == null) {
Log.i(TAG, "No net type");
if (isAdbWifiChecked) {
mEnableWifiAdb.setSummary(getResources()
.getString(R.string.enable_wifi_adb_openwifi));
}
} else {
Log.i(TAG, "Net Type:" + net.getTypeName());
}
State wifi = connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI).getState();
if (wifi == State.CONNECTED || wifi == State.CONNECTING) {
Log.i(TAG, "wifi connected");
WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
int ipAddress = wifiInfo.getIpAddress();
String ipAddressString = (ipAddress & 0xFF) + "." + ((ipAddress >> 8) & 0xFF) + "."
+ ((ipAddress >> 16) & 0xFF) + "." + (ipAddress >> 24 & 0xFF);
if (isAdbWifiChecked) {
mEnableWifiAdb.setSummary(
getResources().getString(
R.string.enable_wifi_adb_connected_summary, ipAddressString));
}
Log.i(TAG, getResources().getString(
R.string.enable_wifi_adb_connected_summary, ipAddressString));
} else if (wifi == State.DISCONNECTED || wifi == State.DISCONNECTING) {
Log.i(TAG, "wifi disconnected");
if (isAdbWifiChecked) {
mEnableWifiAdb.setSummary(
getResources().getString(R.string.enable_wifi_adb_openwifi));
}
Log.i(TAG, getResources().getString(
R.string.enable_wifi_adb_connected_summary));
}
}
};
上面的代码主要是当【Wifi调试】开关打开的时候，来用动态表示Android手机的Wifi连接状态，如果wifi未连接，就提示“Wifi没连接，请连接wifi”，如果Wifi连接了，就动态的将从DHCP服务器获取的IP地址显示出来，如ip地址为192.168.107.201的时候就显示，"Wifi调试已打开,在电脑端你可以输入以下命令进行调试:adb connect 192.168.107.201:5555"======================================================================================================
好吧，在packages/apps/Settings/，即Settings APP层面的代码写完了，下面来说说调用的两个接口怎么实现。android.os.SystemProperties.set("sys.connect.adb.wifi", "1");android.os.SystemProperties.set("sys.connect.adb.wifi", "0");
首先找到frameworks/base/core/java/android/os/SystemProperties.java文件，找到set(String key, String val)方法，代码如下，发现调用了native_set(key, val)方法。 /**
* Set the value for the given key.
* @throws IllegalArgumentException if the key exceeds 32 characters
* @throws IllegalArgumentException if the value exceeds 92 characters
*/
public static void set(String key, String val) {
if (key.length() > PROP_NAME_MAX) {
throw new IllegalArgumentException("key.length > " + PROP_NAME_MAX);
}
if (val != null && val.length() > PROP_VALUE_MAX) {
throw new IllegalArgumentException("val.length > " +
PROP_VALUE_MAX);
}
native_set(key, val);
}native_set(key, val)方法定义如下：private static native void native_set(String key, String def);
该接口类在初始化运行环境中注册对应的cpp接口android_os_SystemProperties.cpp，实际操作通过JNI调用的是cpp文件对应的接口：frameworks/base/core/jni/AndroidRuntime.cpp
namespace android {
extern int register_android_os_SystemProperties(JNIEnv *env);
}
frameworks/base/core/jni/android_os_SystemProperties.cpp
static void SystemProperties_set(JNIEnv *env, jobject clazz,
jstring keyJ, jstring valJ)
{
int err;
const char* key;
const char* val;
if (keyJ == NULL) {
jniThrowNullPointerException(env, "key must not be null.");
return ;
}
key = env->GetStringUTFChars(keyJ, NULL);
if (valJ == NULL) {
val = ""; /* NULL pointer not allowed here */
} else {
val = env->GetStringUTFChars(valJ, NULL);
}
err = property_set(key, val);
env->ReleaseStringUTFChars(keyJ, key);
if (valJ != NULL) {
env->ReleaseStringUTFChars(valJ, val);
}
if (err < 0) {
ALOGE("setproperty key=%s value=%s err=%d\n", key, val, err);
jniThrowException(env, "java/lang/RuntimeException",
"failed to set system property");
}
}
好了，关于该android.os.SystemProperties.set()方法的分析，可以参考http://blog.csdn.net/ameyume/article/details/8056492http://www.blogjava.net/anymobile/articles/301989.html
下面直接写下面两个接口的实现
android.os.SystemProperties.set("sys.connect.adb.wifi", "1");android.os.SystemProperties.set("sys.connect.adb.wifi", "0");
在device/lentek/lentk6735_66t_l1/E580/init.rc文件中加入下面的代码，其中E580是项目的名称。#added by ouyang start connect adb with wifi
on property:sys.connect.adb.wifi=1
setprop service.adb.tcp.port 5555
stop adbd
start adbd
on property:sys.connect.adb.wifi=0
setprop service.adb.tcp.port ""
stop adbd
start adbd
#added by ouyang end connect adb with wifi上面代码就是当调用android.os.SystemProperties.set("sys.connect.adb.wifi", "1");和sys.connect.adb.wifiandroid.os.SystemProperties.set("sys.connect.adb.wifi", "0");接口的时候的具体实现，即"sys.connect.adb.wifi"属性设置为1的时候，监听5555端口， "sys.connect.adb.wifi"属性设置为0的时候，不监听任何端口
====================================================================================好了，下面来再一次测一测该功能怎么样，重新打开wifi,重新打开【Wifi调试】开关，显示如下：
可以看出来，此时Android手机的IP地址是192.168.107.168，因此下面在PC端测试看是否可以用adb wifi无线调试，使用命令adb connect 192.168.107.168连接,adb disconnect 192.168.107.168断开连接，如下图所示：
