Android WifiManager - 到 HEX 或不到 HEX

Question

我正在尝试以编程方式使用 Android 连接到 wifi，但是当我以十六进制输入我的 WEP 密钥时 - Logcat 指出它太长了。当我尝试使用纯文本时 - 它表明它太短（并且永远不会连接）。当我在我构建的应用程序外部手动输入时（只需输入密码：superman），它就会连接！

附言

我正在尝试使用以下 StackOverflow 示例：

How do I connect to a specific Wi-Fi network in Android programmatically?

使用十六进制：

    String networkSSID = "ANDRE-PC_NETWORK";
    String networkPass = "73:75:70:65:72:6d:61:6e";

LOGCAT：

04-04 12:12:13.643: E/wpa_supplicant(594): Line 0: Too long WEP key 0 '"73:75:70:65:72:6d:61:6e"'.
04-04 12:12:13.643: E/WifiConfigStore(479): failed to set wep_key0: "73:75:70:65:72:6d:61:6e"
04-04 12:12:13.793: I/ActivityManager(479): Displayed com.nfc.linked/.Connect: +855ms
04-04 12:12:16.283: W/GAV2(3422): Thread[Service Reconnect,5,main]: Connection to service failed 1

没有十六进制：

  String networkSSID = "ANDRE-PC_NETWORK";
  String networkPass = "superman";

LOGCAT：

04-04 12:23:10.913: E/wpa_supplicant(594): Line 0: Invalid WEP key length 8 - this network block will be ignored

试试：

String networkPass = "73757065726d616e";
