下面的方法enableHotspot適用於開放網絡，但如果我使用那些未註釋的配置設置WPA2網絡，wifi綁定仍會保留約10秒鐘，沒有執行任何其他操作或觸摸屏幕，操作系統崩潰，我得到一個黑屏。 3秒後，它返回禁用wifi tethering並關閉應用程序。 。Galaxy Note - 使用WPA2打開wifi共享時，Android操作系統崩潰（而不是應用程序）
如果我運行上的銀河標籤7" 或中國裝置中，通過自身的設備重啓相同的過程
這裏是上面提到的方法：
public static void enableHotspot(String networkSSID,String networkPass, Context context){
// Enable tethering
WifiConfiguration config = new WifiConfiguration();
config.SSID = networkSSID;
//WPA2
config.hiddenSSID = true;
config.preSharedKey = quoteNonHex(networkPass, 64);
config.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);
config.allowedProtocols.set(WifiConfiguration.Protocol.RSN); // For WPA2
config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_EAP); //this needs a server radius
config.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
config.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
//Simpler WPA2
//config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
//config.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
//config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
//OPEN
//config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
WifiApManager wapm = new WifiApManager(context);
wapm.setWifiApEnabled(config, true);
Log.d("","Wifi Tethering is enabled.");
}
private static String quoteNonHex(String value, int... allowedLengths) {
return isHexOfLength(value, allowedLengths) ? value : convertToQuotedString(value);
}
private static boolean isHexOfLength(CharSequence value, int... allowedLengths) {
if (value == null || !HEX_DIGITS.matcher(value).matches()) {
return false;
}
if (allowedLengths.length == 0) {
return true;
}
for (int length : allowedLengths) {
if (value.length() == length) {
return true;
}
}
return false;
}
