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

:/$setprop service.adb.tcp.port 5555:/$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：

packages/apps/Settings/res/values-zh-rCN/strings.xml 中加入：

        
    
     Wifi调试
        
    
     Wifi没连接，请连接wifi
        
    
     连接Wifi后启用调试模式
        
    
     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 
     
      %1$s
     :5555
        
    

        
    
     Wifi debugging
        
    
     Wifi is not connected,please turn wifi on and connect it
        
    
     Debug mode when Wifi is connected
        
    
     adb wifi is on,from your computer run:\n         			adb connect 
     
      %1$s
     :5555
         
    

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);

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

       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

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);

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));			}		}	};

======================================================================================================

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);

frameworks/base/core/jni/AndroidRuntime.cpp

namespace android {      extern int register_android_os_SystemProperties(JNIEnv *env);}

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");    }}

http://blog.csdn.net/ameyume/article/details/8056492

http://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 wifion property:sys.connect.adb.wifi=1	setprop service.adb.tcp.port 5555	stop adbd	start adbdon property:sys.connect.adb.wifi=0	setprop service.adb.tcp.port ""	stop adbd	start adbd#added by ouyang end connect adb with wifi

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：
