android 开启wifi热点api
2016-3-13 android
android默认开启wifi热点方式只能通过设置-移动网络共享-便携式wlan热点,为了开启一个热点要进行3部操作,实属麻烦!
因此通过网上查资料,实现wifi热点的一键启动!
通过google获知,android把wifi相关的api给隐藏了,因此只能通过反射机制进行调用!
/**
* Start AccessPoint mode with the specified
* configuration. If the radio is already running in
* AP mode, update the new configuration
* Note that starting in access point mode disables station
* mode operation
* @param wifiConfig SSID, security and channel details as
* part of WifiConfiguration
* @return {@code true} if the operation succeeds, {@code false} otherwise
*
* @hide Dont open up yet
*/
public boolean setWifiApEnabled(WifiConfiguration wifiConfig, boolean enabled) {
try {
mService.setWifiApEnabled(wifiConfig, enabled);
return true;
} catch (RemoteException e) {
return false;
}
}
配置AP的选项是属于wifi管理的一部分!获取当前系统wifi实例的方式如下:
WifiManger manager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
获取当前ap状态的方式如下:
public Boolean getApState() {
Boolean bApState = FALSE;
try {
Method method = manager.getClass().getMethod("isWifiApEnabled");
bApState = (Boolean)method.invoke(manager);
} catch (Exception e) {
e.printStackTrace();
bApState = FALSE;
}
return bApState;
}
配置ap使用的类为:WifiConfiguration //本例直接采用默认配置好的
public WifiConfiguration getApConfiguration() {
WifiConfiguration apConfigure = new WifiConfiguretion();
return apConfigure;
}
使能ap方式如下:public void setWifiAp(Boolean bOpen) {
if (bOpen) {
if (getApState()) {
return;
}
manager.setWifiEnabled(false);
}
try {
Method method = manager.getClass().getMethod("setWifiApEnabled", WifiConfiguration.class, Boolean.TYPE);
method.invoke(manager, getApConfiguration()/*采用默认的配置,则置为null*/, bOpen);
} catch (Exception e) {
e.printStackTrance();
}
}
