Android系统移植与调试之-------)如何添加一个adb wifi无线调试的功能【开发者选项】-【Wifi调试】_wifi adb

wifi adb

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

?
1
2
3
:/$setprop service.adb.tcp.port 5555
:/$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)

?
1
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:

?
1
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:

?
1
<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 --><span style= "font-family: Arial, Verdana, sans-serif;" >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:</span>

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

?
1
<!-- 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:
?
1
<!-- 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:

 

?
1
2
3
4
5
//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:

 

?
1
2
3
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:

 

?

2
3
4
5
6
7
8
9
10
11
//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:

?
1
2
3
4
5
6
7
8
9
10
11
12
13
14
/// 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:

?
1
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);

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/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 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:
