androidwifi编程
㈠ Android系统手机WiFi通信功能开发
IDE就用Eclipse就足够了 对于Wifi的控制 android.net.wifi下有不少接口 但是要分别开发电视端和手机端 多思考就能找到电视和手机之间通讯的最好方式
㈡ 安卓怎么编程实现wifi安全检测
在Android中对Wifi操作，android本身提供了一些有用的包，在android.net.wifi包下面。主要包括以下几个类和接口： 1.ScanResult 主要用来描述已经检测出的接入点，包括接入点的地址，接入点的名称，身份认证，频率，信号强度等信息。 2.WifiConfiguration Wifi网络的配置，包括安全设置等。 3.WifiInfo wifi无线连接的描述，包括接入点，网络连接状态，隐藏的接入点，IP地址，连接速度，MAC地址，网络ID，信号强度等信息。这里简单介绍一下这里的方法: getBSSID() 获取BSSID getDetailedStateOf() 获取客户端的连通性 getHiddenSSID() 获得SSID 是否被隐藏 getIpAddress() 获取IP 地址 getLinkSpeed() 获得连接的速度 getMacAddress() 获得Mac 地址 getRssi() 获得802.11n 网络的信号 getSSID() 获得SSID getSupplicanState() 返回具体客户端状态的信息 4.WifiManager 这个不用说，就是用来管理我们的wifi 连接，这里已经定义好了一些类，可以供我们使用。 获取WIFI网卡的状态 WIFI网卡的状态是由一系列的整形常量来表示的。 1.WIFI_STATE_DISABLED : WIFI网卡不可用（1） 2.WIFI_STATE_DISABLING : WIFI网卡正在关闭（0） 3.WIFI_STATE_ENABLED : WIFI网卡可用（3） 4.WIFI_STATE_ENABLING : WIFI网正在打开（2） （WIFI启动需要一段时间） 5.WIFI_STATE_UNKNOWN : 未知网卡状态 最重要的一个就是 你要设置权限 最重要的一个就是 你要设置权限 希望帮助到你

最简单就是,安装xampp服务器,已经带有mysql,用android连接就行了

㈤ 如何以编程方式创建和读取的WEP / EAP无线网络配置中的Android
1. 第1部分：创建一个无线网络的WEP配置编程 。
第2部分：阅读一个WEP无线网络配置编程
再次Straighforward。
第3部分：读一个EAP的WiFi配置编程
现在，这是棘手的。你可以找到它通过香草的Android用户界面中WifiDialog.java节省了EAP的WiFi配置的代码。唔够方便我们在我们的应用程序的代码，那么不要！如果你碰巧去尝试这一点，你会得到错误说找不到符号eap，phase，client_cert等。有点详细的调查EnterpriseFieldis private内WiFiConfiguration类和所有的符号，我们无法找到是类型EnterpriseField。好了，我们已经打了一个路障，我们需要这些字段读取/保存一个EAP配置，但我们并没有以编程方式访问他们！Java Reflection API救援
好吧，我不是一个Java专家，所以我不会越来越到的反射API的细节，例如，你可以谷歌的教程或到达这里。
为了保持简短而亲切，反射API允许你检查类，接口，字段在不知道的类，方法等，还可以实例化新对象，并获取/设置现场reflection.And，重要的是能思考的帮助您访问私有的类里面嗯，这是我们需要做的不是吗？ :)
让我们来检查代码示例现在它显示了如何读取一个EAP的WiFi反射API。作为一个片段将记录配置到一个文件，并将其保存在SD卡....非常漂亮..诶;)反射API概述一点点，我相信ING下面的代码是很容易。
private static final String INT_PRIVATE_KEY = "private_key";
private static final String INT_PHASE2 = "phase2";
private static final String INT_PASSWORD = "password";
private static final String INT_IDENTITY = "identity";
private static final String INT_EAP = "eap";
private static final String INT_CLIENT_CERT = "client_cert";
private static final String INT_CA_CERT = "ca_cert";
private static final String INT_ANONYMOUS_IDENTITY = "anonymous_identity";
final String INT_ENTERPRISEFIELD_NAME = "android.net.wifi.WifiConfiguration$EnterpriseField";
第4部分：储存的EAP无线网络配置编程
如果你已经读过的部分3，您已经了解了反射mojo，在这里工作，如果你是直接跳跃到本节，请在第3部分的代码段之前，看了介绍，你会加快速度通过代码来这里微风！

㈥ Android 代码设置Wifi 热点密码设置的问题
netConfig.allowedKeyManagement.set(4);
//WifiConfiguration.KeyMgmt.WPA2_PSK=4，但是不能直接拿到，所以参数直接设成4就行了
㈦ android开发中如果我想代码实现打开wifi热点如何实现
1·申请权限：
android.permission.ACCESS_WIFI_STATE
android.permission.CHANGE_WIFI_STATE
android.permission.WAKE_LOCK
2·获取WifiManager
wifiManager = (WifiManager) this.getSystemService(Context.WIFI_SERVICE);
3·开启、关闭wifi
if (wifiManager.isWifiEnabled()) {
wifiManager.setWifiEnabled(false);
} else {
wifiManager.setWifiEnabled(true);
}
4·注意
如果遇到force-close, 选wait即可, 因为启动wifi需要几秒钟, UI如果5妙钟还没反映的话, 系统会给你这个force close exception
PS：我以前做过设计读取系统硬件信息的时候用过，但是很长时间没用了，这段注释是从网上来的，希望能帮到你。
