我们正在尝试以编程方式打开 wifi 热点，但有时它会进入无限循环并且不会打开，但大多数情况下它可以工作。这是它挂起的行“while (!(Boolean) isWifiApEnabledMethod.invoke(wifiManager)) { Thread.sleep(500); };” 整个代码放在下面。这只是 Android 5.0/5.1 设备的问题。任何输入将不胜感激。

    WifiManager wifiManager = (WifiManager)getActivity().getApplicationContext().getSystemService   (Context.WIFI_SERVICE);

    //If Wifi is ON then switch it OFF
    if (wifiManager.isWifiEnabled()) {
        wifiManager.setWifiEnabled(false);
    }

    WifiConfiguration netConfig = new WifiConfiguration();
    Random random = new Random();
    int iRandomKey = random.nextInt(65536);

    netConfig.SSID = "TestHotspot";
    netConfig.status = WifiConfiguration.Status.ENABLED;
    netConfig.priority = 40;
    //hiding SSID,
    netConfig.hiddenSSID = true;
    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.WEP40);
    netConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP104);
    netConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
    netConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
    netConfig.preSharedKey = "testpassword";

    final String RingOfFire_Ssid = netConfig.SSID;
    final String RingOfFire_password = netConfig.preSharedKey;

    try {
        Method setWifiApMethod = wifiManager.getClass().getMethod("setWifiApEnabled",   WifiConfiguration.class, boolean.class);
        boolean apstatus = (Boolean) setWifiApMethod.invoke(wifiManager, netConfig, true);
        Log.d("ConnectWIFI:", "apstatus" + ":" + apstatus);

        Method isWifiApEnabledMethod = wifiManager.getClass().getMethod("isWifiApEnabled");
        while (!(Boolean) isWifiApEnabledMethod.invoke(wifiManager)) {
            Thread.sleep(500);
        };

        Method getWifiApConfigurationMethod = wifiManager.getClass().getMethod("getWifiApConfiguration");
        netConfig = (WifiConfiguration) getWifiApConfigurationMethod.invoke(wifiManager);

        Log.d("ConnectWIFI:", netConfig.SSID + ":" + netConfig.preSharedKey + ":" + "Hotspot");

    } catch (Exception e) {
        Log.e(this.getClass().toString(), "", e);
    }

我们进一步探索，当我们使用这种方法时，我们得到了更好的行为

    Class<?> cls=WifiManager.class; 
   for (Method method:cls.getDeclaredMethods()){ 
   String methodName=method.getName(); 
   if (methodName.equals("getWifiApState")){ getWifiApState=method; }
   else if (methodName.equals("isWifiApEnabled")){ isWifiApEnabled=method; }
   else if (methodName.equals("setWifiApEnabled")){ setWifiApEnabled=method; }
   else if (methodName.equals("getWifiApConfiguration")) {       getWifiApConfiguration=method; } }

谢谢
