安卓设置热点ssid和密码

基本概念

关于WifiConfiguration基本信息参看文章：
点此查看
也可以上官网去查看详细的api介绍连接
在此就截取部分别人已经翻译好的：
子类
class WifiConfiguration.AuthAlgorithm 公认的IEEE 802.11认证算法
class WifiConfiguration.GroupCipher 公认的组密码
class WifiConfiguration.KeyMgmt 公认的密钥管理方案
class WifiConfiguration.PairwiseCipher 公认的WPA配对密码
class WifiConfiguration.Protocol 公认的安全协议
class WifiConfiguration.Status 网络配置的可能状态
（WifiConfiguration.AuthAlgorthm用来判断加密方法。
WifiConfiguration.GroupCipher获取使用GroupCipher 的方法来进行加密。
WifiConfiguration.KeyMgmt获取使用KeyMgmt 进行。
WifiConfiguration.PairwiseCipher获取使用WPA 方式的加密。
WifiConfiguration.Protocol获取使用哪一种协议进行加密。
wifiConfiguration.Status获取当前网络的状态。

字段
public String BSSID 当设置了这个字段，这个网络配置只能被用于与访问点关联的指定MAC
public String FQDN AAA或者RADIUS等服务器的完全合格域名
public String SSID Wifi网络名称
public BitSet allowedAuthAlgorithms 该配置支持的身份验证协议集合
public BitSet allowedGroupCiphers 该配置所支持的组密码集合
public BitSet allowedKeyManagement 该配置所支持的密钥管理集合
public BitSet allowedPairwiseCiphers 该配置所支持的WPA配对密码集合
public BitSet allowedProtocols 该配置所支持的安全协议集合
public WifiEnterpriseConfig enterpriseConfig 企业详细配置指定的EAP方法，证书以及EAP相关的其他设置
public boolean hiddenSSID 设置该项会使一个网络不广播其SSID，因此这种特定的SSID只能用于浏览
public int networkId 客户端用于识别网络配置的ID
public String preSharedKey WPA-PSK使用的预共享密钥
public int priority 当选择了一个相关的网络访问点时，优先级决定了一个通过wpa客户端访问网络的优先权

设置热点及ssid

由于项目需求，我们需要在项目中去设置打开手机热点并设置ssid和密码，这个需求呢好像还挺多人有过的，但是网上一搜，大多数人的代码发现实现不了，要吗是不谦容5.0,6.0,7.0手机，要吗就是手机设置的热点无法连接上，还有的就是热点设置后没有密码，变成开发式。

最初实现方式

最初我参考了网上的代码实现如下，但一直无法设置热点的密码。
使用此方式设置，问题我一直没找到，希望有知道的哥们给我留言，帮我解困。

 private void startWifiAp() {if (mWifiManage.isWifiEnabled()) {mWifiManage.setWifiEnabled(false);}Method method = null;try {method = mWifiManage.getClass().getMethod("setWifiApEnabled",WifiConfiguration.class, boolean.class);method.setAccessible(true);WifiConfiguration netConfig = new WifiConfiguration();netConfig.SSID =mSsid;netConfig.preSharedKey =  mPassword;netConfig.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);netConfig.allowedProtocols.set(WifiConfiguration.Protocol.RSN);netConfig.allowedProtocols.set(WifiConfiguration.Protocol.WPA);netConfig.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);netConfig.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);netConfig.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);netConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);netConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);method.invoke(mWifiManage, netConfig,true);} catch (Exception e) {}}
}

更改实现方式

鉴于上述的方式存在的问题，综合资料我更改了实现方式：

}

使用方式： WifiAPUtil.getInstance(this).turnOnWifiAp(mSsid, mPassword, WifiAPUtil.WifiSecurityType.WIFICIPHER_WPA2);

目前我在安卓5.0,6.0,7.0机子上都测试过没有问题，欢迎大家帮我解决第一个问题。
