联芯代码如何去掉QuickSetting下蓝牙及wifi快捷图标
QuickSetting代码在SystemUI目录下，具体代码如下：
而控制quicksetting下各功能是否显示是由QuickSettingsController类来控制的。
在QuickSettingsController下找到loadTiles方法；
boolean bluetoothSupported = QSUtils.deviceSupportsBluetooth() && mContext.getPackageManager().hasSystemFeature(PackageManager.FEATURE_BLUETOOTH);
boolean mobileDataSupported = QSUtils.deviceSupportsMobileData(mContext);
boolean gpsSupported = QSUtils.deviceSupportsGps(mContext);
boolean autorotateSupported = QSUtils.deviceSupportsAutorotate(mContext);
boolean wifiSupported =
mContext.getPackageManager().hasSystemFeature(PackageManager.FEATURE_WIFI);
if (!bluetoothSupported) {
TILES_DEFAULT.remove(TILE_BLUETOOTH);
if (!mobileDataSupported) {
TILES_DEFAULT.remove(TILE_MOBILEDATA);
if (!gpsSupported) {
TILES_DEFAULT.remove(TILE_GPS);
if (!autorotateSupported) {
TILES_DEFAULT.remove(TILE_AUTOROTATE);
if(!wifiSupported) {
TILES_DEFAULT.remove(TILE_WIFI);
(frameworks\base\services\java\com\android\server\pm)
mPM.hasSystemFeature(name)经过AIDL实际上调用到文件PackageManagerService.java 。
mAvailableFeatures里面的内容是通过读取/system/etc/permissions下面的文档。
android4.0 及以上 版本里 ，如果在settings下看不到wifi和bluetooth两个菜单选项，这是因为在setting里，对系统是否有特定的模块加上了判断，如果没有就不显示。android4.0的模块判断函数：getPackageManager().hasSystemFeature(String string).通过该函数判断系统是否有特定的模块功能。
例如判断是否有 wifi 和 蓝牙模块的具体代码：
getPackageManager().hasSystemFeature(PackageManager.FEATURE_WIFI);
getPackageManager().hasSystemFe(PackageManager.FEATURE_BLUETOOTH);
PackageManager这些字符串 存在system/etc/permissions/xxxx.xml文件里，它们一般从/framework/base/data/etc/xxx.xml复制过来。
PackageManager.FEATURE_BLUETOOTH = "android.hardware.wifi"
PackageManager.FEATURE_BLUETOOTH = "android.hardware.bluetooth"
解决wifi和蓝牙不显示方法：
一、直接把包含对应 feature 的xml文件复制到system/etc/permissions/目录下，相当于加上系统所具有的具体模块的功能配置文件;
二、修改product_copy.mk文件，添加相应的设备。

CV： {{ getCv() }}Android4.2的源码android-17\com\android\commands目录下较之前的版本多了一个settings命令，查看其中的SettingsCmd.java文件，末尾有命令的帮助信息：
private static void printUsage() {
System.err.println("usage:
settings [--user NUM] get namespace key");
System.err.println("
settings [--user NUM] put namespace key value");
System.err.println("\n'namespace' is one of {system, secure, global}, case-insensitive");
System.err.println("If '--user NUM' is not given, the operations are performed on the owner user.");
选项中的key为什么值，很难从帮助信息中看出，从代码中查看该key值是在android.provider.Settings中定义了。
该命令可以很方便的更改系统设置中的参数（如修改系统默认输入法），给出几个使用该命令的例子：
#获取系统默认输入法
#默认搜狗输入法
C:\Users\Administrator&adb shell settings get secure default_input_method
com.sohu.inputmethod.sogouoem/.SogouIME
#默认为Appium使用中文输入时安装的输入法
C:\Users\Administrator&adb shell settings get secure default_input_method
io.appium.android.ime/.UnicodeIME
#put命令更改默认输入法（将io.appium.android.ime/.UnicodeIME改为com.sohu.inputmethod.sogouoem/.SogouIME）
C:\Users\Administrator&adb shell settings put secure default_input_method com.sohu.inputmethod.sogouoem/.SogouIME
#获取亮度是否为自动获取
C:\Users\Administrator&adb shell settings get system screen_brightness_mode
#获取当前亮度值
C:\Users\Administrator&adb shell settings get system screen_brightness
#更改亮度值（亮度值在0—255之间）
C:\Users\Administrator&adb shell settings put system screen_brightness 150
#获取屏幕休眠时间
C:\Users\Administrator&adb shell settings get system screen_off_timeout
#更改休眠时间，10分钟
C:\Users\Administrator&adb shell settings put system screen_off_timeout 600000
#获取日期时间选项中通过网络获取时间的状态，1为允许、0为不允许
C:\Users\Administrator&adb shell settings get global auto_time
#更改该状态，从1改为0
C:\Users\Administrator&adb shell settings put global auto_time 0
以及获取、修改wifi状态（wifi_on）、飞行模式（airlpane_mode_on）等，这里也是appium中getNetworkConnection获得设备网络状态的方法。

标准系统才有用，自己裁剪过的就可能不同了。
嗯，需要用到的时候，要自己尝试才知道能不能使用，还有其中的system、global、secure这个个namespace要用正确才行。
关闭和打开WIFI 怎么用？
adb shell settings put global wifi_on 1，不是任何机型都支持
adb shell svc wifi disable
adb shell svc wifi enable
当需要打开或者关闭数据业务的时，把wifi修改为data就OK了
强制静音 怎么用？
有木有给wifi设置代理的命令

以Atheros71xx为例，修改路径为：trunk/kernel/mac80211/files/lib/wifi/mac80211.sh代码的尾部即为/etc/config/wireless文件的内容。
可修改为出厂时即启动无线，无线的SSID为指定值等等

WiFi设置储存在/etc/config/wireless中（目前支持Broadcom, Atheros 和mac80211）。当第一次启动路由器时，将会自动检测你的卡并且创建简单的配置文件。默认情况下 'option network lan' 是被注释掉的。它提供了一个非安全的无线网络共享。
The WiFi settings are configured in the file&/etc/config/wireless(currently supported on Broadcom, Atheros and mac80211). When booting the router for the first time it should detect your card and create
a sample configuration file. By default 'option network lan' is commented. This prevents unsecured sharing of the network over the wireless interface.
每一个无线驱动都有自己的配置脚本/lib/wifi/driver_name.sh&，用来处理驱动选项和配置。这个脚本也调用特殊二进制，例如Broadcom的w1c，或者atheros的hostapd 和wpa_supplicant 。
Each wireless driver has its own configuration script in&/lib/wifi/driver_name.sh&which handles driver specific options and configurations. This script is also calling driver specific binaries like
wlc for Broadcom, or hostapd and wpa_supplicant for atheros.
使用不同的架构配置是因为不同的驱动配置。
The reason for using such architecture, is that it abstracts the driver configuration.
这个文件里有两个类型的配置段。wifi-device针对物理wifi接口，wifi-iface配置了一个在wifi-device之上的虚拟接口（需要被驱动支持）。
There are two types of config sections in this file. The 'wifi-device' refers to the physical wifi interface and 'wifi-iface' configures a
virtual interface on top of that (if supported by the driver).

&OpenWrt supports both 802.1x client
and Access Point configurations. 802.1x client is only working with Atheros or mac80211 drivers. Configuration only supports EAP types TLS, TTLS or PEAP.
&There are certain
limitations when combining modes. Only the following mode combinations are supported:
Broadcom:&
1x&sta, 0-3x&ap1-4x&ap1x&adhoc1x&monitor
WDS links can only be used in pure AP mode and cannot use WEP (except when sharing the settings with the master interface, which is done automatically).
1x&sta, 0-Nx&ap1-Nx&ap1x&adhoc
N is the maximum number of VAPs that the module allows, it defaults to 4, but can be changed by loading the module with the maxvaps=N parameter.
&Since we currently only
support thread different wireless drivers : Broadcom, Atheros and mac80211, you might be interested in adding support for another driver like Ralink RT2x00, Texas Instruments ACX100/111.
这些驱动的特定脚本要放在/lib/wifi/.脚本必须包括以下几个方法：
The driver specific script should be placed in&/lib/wifi/.shand has to include several functions providing :
检测驱动是否存在detection of the driver presence使能/禁用wifi接口enabling/disabling the wifi interface(s)配置读取和设置configuration reading and setting第三方程序的调用(nas, supplicant) third-party programs calling (nas, supplicant)
每个驱动都应该附加到全局变量DRIVERS 中：
Each driver script should append the driver to a global DRIVERS variable :
&，这个方法将会分析/etc/config/wireless并且保证没有不兼容的配置，例如在ad-hoc模式下隐藏了SSIDS。如果你的设备支持很多配置选项，将是一件非常麻烦的事。&&
&，这个方法将会启动wifi设备，并且可以建立特定的配置文件，例如针对WPA鉴别者或者提供者。
&，这个方法将会关闭wifi设备和它的所有虚拟接口。
&，这个方法寻找驱动可用的接口。为新设备编写的配置模版应该输出到stdout。还必须在建立新模板时，检查是否已经存在属于该接口的配置段。
这个配置文件被分为段和选项/值两部分。
The config files are divided into sections and options/values.
每一个段都有一个类型，但是不需要都有名字。每个选项都有一个名字和一个值并且分配到一个段中。
Every section has a type, but does not necessarily have a name. Every option has a name and a value and is assigned to the section it was written under.
语法 Syntax:
每个参数都必须是一个单独的字符串，并且被格式化为shell方法的参数。
Every parameter needs to be a single string and is formatted exactly like a parameter for a shell function. The same rules for Quoting and special characters also apply, as it is parsed by the shell.
为了能够加载配置文件，你需要include通用方法：
To be able to load configuration files, you need to include the common functions with:
这样你就可以使用config_load&来加载配置文件。这个函数首先检查的文件名，然后从&/etc/config中调用它。Then
you can use&config_load&to load config files. The function first checks for&as
absolute filename and falls back to loading it from&/etc/config&(which is the most common way of using it).
如果你希望使用特殊的回调函数来调用段或者选项，在使用config_load前你需要首先定义你的shell方法（在including&/etc/functions.sh之后），如下。
If you want to use special callbacks for sections and/or options, you need to define the following shell functions before running&config_load(after including&/etc/functions.sh):
你还可以从You can also alter&option_cbfrom&config_cbbased on the section type. This allows you to process every single config section based on its
type individually.
config_cb在每个新段开始后都会运行（在选项被处理之前）。可以通过CONFIG_SECTION变量查看最后的配置段。在config_load完成之后也会调用config_cb（不需要新的配置段）。这就可以再所有选项被处理之前或者之后处理配置段。
config_cbis run every time a new section starts (before options are being processed). You can access the last section through the&CONFIG_SECTIONvariable.
Also an extra call to&config_cb(without a new section) is generated after&config_loadis done. That allows you to process sections both before
and after all options were processed.
Another way of iterating on config sections is using the&config_foreach&command.
语法Syntax:
This command will run the supplied function for every single config section in the currently loaded config. The section name will be passed to the function as argument 1. If the section type is added to the command line, the function will only be called for
sections of the given type.
You can access already processed options with the&config_getcommand Syntax:
In busybox ash the three-option&config_getis faster, because it does not result in an extra fork, so it is the preferred way.
Additionally you can also modify or add options to sections by using the&config_set&command.
If a config section is unnamed, an automatically generated name will be assigned internally, e.g.&cfg1,&cfg2, ...
While it is possible, using unnamed sections through these autogenerated names is strongly discouraged. Use callbacks orconfig_foreachinstead.
因为OpenWRT使用它自己的初始化脚本系统，所有其他初始化脚本必须安装在/etc/init.d/&name，使用/etc/rc.common作为封装。
Because OpenWrt uses its own init script system, all init scripts must be installed as&/etc/init.d/&nameuse/etc/rc.commonas
a wrapper.
例子:&/etc/init.d/httpd
正如你所看到的，这个脚本并不实际分析命令行参数。这些都是/etc/rc.common来完成的。
as you can see, the script does not actually parse the command line arguments itself. This is done by the wrapper script/etc/rc.common.
start()and&stop()是基本的方法，几乎所有的初始化脚本都需要提供。start()将会在用户执行/etc/init.d/httpd start或者在系统启动的时候（如果该脚本使能了并且没有）执行。
start()and&stop()are the basic functions, which almost any init script should provide.&start()is
called when the user runs/etc/init.d/httpd startor (if the script is enabled and does not override this behavior) at system boot time.
使能和禁用初始化脚本是通过/etc/init.d/&name&enableor&/etc/init.d/&name&disable。实际上是在/etc/rc.d中建立或撤销连接，它在启动的时候由/etc/init.d/rcS来处理。
Enabling and disabling init scripts is done by running&/etc/init.d/&name&enableor&/etc/init.d/&name&disable.
This creates or removes symbolic links to the init script in&/etc/rc.d, which is processed by&/etc/init.d/rcSat boot time.
这些脚本的默认启动顺序在初始化脚本的START变量中。改变它需要重新该脚本的运行/etc/init.d/&nameenable&。
The order in which these scripts are run is defined in the variable&STARTin the init script. Changing it requires running/etc/init.d/&name&enable&again.
你还可以重写这些标准的初始化脚本函数：You can also override these standard init script functions:
Commands to be run at boot time. Defaults to&start()restart()&
Restart your service. Defaults to&stop(); start()reload()&
Reload the configuration files for your service. Defaults to&restart()
你也可以通过建立适当的函数并且在EXTRA_COMMANDS变量里声明他们来自定义命令。帮助文档加在EXTRA_HELP里。
You can also add custom commands by creating the appropriate functions and referencing them in theEXTRA_COMMANDSvariable. Helptext is added in&EXTRA_HELP.
为了能够访问网络功能，你需要通过执行如下命令来include一些必须得shell脚本。
To be able to access the network functions, you need to include the necessary shell scripts by running:
一些协议，如PPP可能在运行的时候改变接口名称（例如eth0=&&ppp0for PPPoE）。这就是为什么你要运行scan_interfaces，而不仅仅是从配置中直接读取变量。在运行scan_interfaces之后，ifname选项将始终包含有效地接口名称（用来IP通信），并且如果物理设备名字和他不同，物理设备名称将被储存在device选项中。这就意味着在scan_interfaces之后执行config_get
lan ifname可能得到与反序执行不同的返回值。
Some protocols, such as PPP might change the configured interface names at run time (e.g.&eth0=&&ppp0for PPPoE). That's why you have to run&scan_interfacesinstead
of reading the values from the config directly. After running&scan_interfaces, the'ifname'option will always contain the effective interface
name (which is used for IP traffic) and if the physical device name differs from it, it will be stored in the&'device'option. That means that running&config_get
lan ifnameafterscan_interfacesmight not return the same result as running it before.
在执行scan_interfaces之后，如下的方法是有效的：
After running&scan_interfaces, the following functions are available:
find_config&interface&
寻找一个带有特定网络接口的配置项looks for a network configuration that includes the specified network interface.setup_interface&interface [config] [protocol]&
将会配置指定的接口，也可以重写网络配置名称或者它使用的协议。will set up the specified interface, 可选的ly overriding the network configuration name or the protocol that it uses.
你可以加入自己的协议处理句柄，通过在/lib/network下增加脚本。提供了如下的两个脚本函数：You can add custom protocol handlers by adding shell scripts to&/lib/network. They provide
the following two shell functions:
scan_&protocolname是可选的并且只在你的协议需要使用一个自定义设备时。例如管道或者一个ppp设备。
scan_&protocolnameis 可选的 and only necessary if your protocol uses a custom device, e.g. a tunnel or a PPP device.

此时web页面wifi页状态显示连接，如图四：
说明：如果上面ping外网不通，可能是DNS没有设置
选一个可用的DNS，如8.8.8.8 为google的DNS服务器地址
可以在web页，DHCP and DNS页面中设置DNS forwardings: 8.8.8.8, save&apply
这样设置之后，就能ping通大网了
接mtgd的笔记本(网口接mtgd&lan口)也可以直接上大网了。
3.直接在命令行下手动配置wifi如下：
可以先删除老的配置文件rm -rf /etc/config/wireless
新建一个配置文件 wifi detect & /etc/config/wireless
在上面生成的配置文件/etc/config/wireless基础上修改，改成如下：
主要设置'disabled'，'channel'，'network'，'mode'，'ssid'，'encryption' ，'key'，'bssid'
即主要设置option参数
设置之后保存退出，再运行wifi命令
root@OpenWrt:/# vi /etc/config/wireless&
config 'wifi-device' 'radio0'
& & & & option 'type' 'mac80211'

& & & & option 'device' 'radio0'
& & & & option 'network' 'wwan' &--------这个地方一定不能为lan，否则连不通，可为wan，wwan等，wwan只是一个别名
& & & & option 'mode' 'sta' & & & &
& & & & option 'ssid' 'TP-LINK_CPN'
& & & & option 'encryption' 'psk2' & & & &
