标题: 关于修改系统最大wifi热点连接数
1，如果单单修改最大连接数目，会导致UI出错的。
/media/doraemon/works/android/mtk/6735/b2/alps_ok/frameworks/base/core/java/android/provider/Settings.java
如下位置：
      /**
      * The max client num of hotspot
      * @hide
      * @internal
      */
      public static final String WIFI_HOTSPOT_MAX_CLIENT_NUM = "wifi_hotspot_max_client_num";

      /**
      * Wifi hotspot default client number
      * @hide
      * @internal
      */
      //zcfdebug-- public static final int WIFI_HOTSPOT_DEFAULT_CLIENT_NUM = 5;
public static final int WIFI_HOTSPOT_DEFAULT_CLIENT_NUM = 50; //zcfdebug++

为什么呢？
这和spinner初始化有关系
/media/doraemon/works/android/mtk/6735/b2/alps_ok/packages/apps/Settings/src/com/android/settings/wifi/WifiApDialog.java：：
      int maxConnValue = System.getInt(mContext.getContentResolver(),System.WIFI_HOTSPOT_MAX_CLIENT_NUM,
                        System.WIFI_HOTSPOT_DEFAULT_CLIENT_NUM);
      //zcfdebug-- mMaxConnSpinner.setSelection(maxConnValue - 1);
mMaxConnSpinner.setSelection(maxConnValue/10 - 1);//zcfdebug++

如果不管显示，实际设置ap连接数量限制在如下文件中修改：
/media/doraemon/works/android/mtk/6735/b2/alps_ok/frameworks/base/services/core/java/com/android/server/NetworkManagementService.java：：
@Override
public void setAccessPoint(WifiConfiguration wifiConfig, String wlanIface) {
      mContext.enforceCallingOrSelfPermission(CONNECTIVITY_INTERNAL, TAG);
      try {
         if (wifiConfig == null) {
            mConnector.execute("softap", "set", wlanIface);
         } else {
            /** M: Hotspot Manager @{ */
            int clientNum = Settings.System.getInt(mContext.getContentResolver(), Settings.System.WIFI_HOTSPOT_MAX_CLIENT_NUM,
                  Settings.System.WIFI_HOTSPOT_DEFAULT_CLIENT_NUM);
            if (isBspPackage()) {
                  //zcfdebug-- clientNum = 8;
clientNum = 50;//zcfdebug++
            }
            /** @} */

            ///M: for Hidden SSID
            String hiddenSSid = (wifiConfig.hiddenSSID == true) ? "hidden" : "broadcast";

            mConnector.execute("softap", "set", wlanIface, wifiConfig.SSID,
                                 hiddenSSid, wifiConfig.channel, getSecurityType(wifiConfig),
                                 new SensitiveArg(wifiConfig.preSharedKey),
                                 wifiConfig.channelWidth,
                                 clientNum);
         }
      } catch (NativeDaemonConnectorException e) {
         throw e.rethrowAsParcelableException();
      }
}

@Override
public void startAccessPoint(
         WifiConfiguration wifiConfig, String wlanIface) {
      mContext.enforceCallingOrSelfPermission(CONNECTIVITY_INTERNAL, TAG);
      try {
         wifiFirmwareReload(wlanIface, "AP");
         if (wifiConfig == null) {
            mConnector.execute("softap", "set", wlanIface);
         } else {
            /** M: Hotspot Manager @{ */
            int clientNum = Settings.System.getInt(mContext.getContentResolver(), Settings.System.WIFI_HOTSPOT_MAX_CLIENT_NUM,
               Settings.System.WIFI_HOTSPOT_DEFAULT_CLIENT_NUM);
            if (isBspPackage()) {
                  //zcfdebug-- clientNum = 8;
clientNum = 50; //zcfdebug++
            }
            /** @} */

            ///M: for Hidden SSID
            String hiddenSSid = (wifiConfig.hiddenSSID == true) ? "hidden" : "broadcast";

            mConnector.execute("softap", "set", wlanIface, wifiConfig.SSID,
                                 hiddenSSid, wifiConfig.channel, getSecurityType(wifiConfig),
                                 new SensitiveArg(wifiConfig.preSharedKey),
                                 wifiConfig.channelWidth,
                                 clientNum);
         }
         mConnector.execute("softap", "startap");
      } catch (NativeDaemonConnectorException e) {
         throw e.rethrowAsParcelableException();
      }
}

这个地方可以直接修改的：
