想在程序里打开softAP模式，网上抄了一段代码
5.0以上手机打不开，5.0以下的手机可以，后来发现是少添加了一个权限
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
public boolean setWifiApEnabled(boolean enabled) {
if (enabled) {
wifiManager.setWifiEnabled(false);
}
try {
WifiConfiguration apConfig = new WifiConfiguration();
apConfig.SSID = "lucien";
apConfig.preSharedKey = "123456789";
apConfig.allowedAuthAlgorithms
.set(WifiConfiguration.AuthAlgorithm.OPEN);
apConfig.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
apConfig.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
apConfig.allowedKeyManagement
.set(WifiConfiguration.KeyMgmt.WPA_PSK);
apConfig.allowedPairwiseCiphers
.set(WifiConfiguration.PairwiseCipher.CCMP);
apConfig.allowedPairwiseCiphers
.set(WifiConfiguration.PairwiseCipher.TKIP);
apConfig.allowedGroupCiphers
.set(WifiConfiguration.GroupCipher.CCMP);
apConfig.allowedGroupCiphers
.set(WifiConfiguration.GroupCipher.TKIP);
Method method = wifiManager.getClass().getMethod(
"setWifiApEnabled", WifiConfiguration.class, boolean.class);
method.setAccessible(true);
return (Boolean) method.invoke(wifiManager, apConfig, enabled);
} catch (Exception e) {
e.printStackTrace();
return false;
}
}
上面这段代码在三星的手机上可以设置密码成功，但是在国产华为、小米、中兴、魅族等手机上可以打开AP模式，
但是设置密码均失败，好吧，这个并不是重点，有空再研究。
