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 -->
<!-- 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
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);
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 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:
