添加wifi adb
https://blog.csdn.net/ouyang_peng/article/details/50370786
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
:/$start adbd
其中setprop是用来设置系统属性的,这里不需要root权限,su即可。可通过adb shell设置,亦可通过手机上安装的Android terminal设置。
2. 电脑端的设置和使用
连接adb,其中phone_ipaddress和portnumber是指手机的ip和前面设置的监听端口号(如5555)
adb connect phone_ipaddress:portnumber
直接adb shell或adb -s 设备shell连接设备
如若要断开则如下:
adb disconnect phone_ipaddress:port
但是每次这样的去设置很繁琐,所以直接在设置中做一个开关就把手机端的设置做好,如下所示:
一、打开开关,并连接Wifi
二、打开开关,没有连接Wifi
三、未打开开关
这样就可以直接进行adb wifi调试了,手机端就不用每次都先用USB调试去设置修改的属性,才能激活adb wifi调试。
======================================================================================================
下面来具体说说实现的思路:
第一步:在【设置】-->【开发者选项】中做一个类似于【USB调试】的开关【Wifi调试】
第二步:【Wifi调试】开关打开就激活监听5555端口,用来进行adb wifi调试,【Wifi调试】开关关闭就不监听5555端口,这样就不能进行adb wifi调试
第三步:在第二步中打开关闭【Wifi调试】开关的时候,调用相应的接口进行设置
第四步:将第三步中要调用的接口写好
1、先在布局中加入该开关
首先找到布局文件,packages/apps/Settings/res/xml/development_prefs.xml,找到【USB调试】开关的相应代码,然后再里面加一个【Wifi调试】开关,代码如下:
- <SwitchPreference
- android:key="enable_adb"
- android:title="@string/enable_adb"
- android:summary="@string/enable_adb_summary"/>
- <!-- added by ouyang start -->
- <SwitchPreference
- android:key="enable_wifi_adb"
- android:title="@string/enable_wifi_adb"
- android:summary="@string/enable_wifi_adb_summary"/>
- - added by ouyang end -->
上面代码中,第一个代码是【USB调试】开关的代码,第二个是我加的【Wifi调试】开关的代码,然后为什么的字符串做相应的国际化操作,代码如下:
packages/apps/Settings/res/values-zh-rCN/strings.xml 中加入:
- <!-- added by ouyang start 2015-12-17 -->
- <string name="enable_wifi_adb">Wifi调试</string>
- <string name="enable_wifi_adb_openwifi">Wifi没连接,请连接wifi</string>
- <string name="enable_wifi_adb_summary">连接Wifi后启用调试模式</string>
- <string name="enable_wifi_adb_connected_summary">Wifi调试已打开,在电脑端你可以输入以下命令进行调试:\n
- adb connect <xliff:g id="ip_address">%1$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/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:
