文章讲述了在Android设备中，为了防止未连接网络时的潜在风险，如何控制WiFi连接时的随机MAC地址。核心代码涉及`config.xml`配置文件和`WifiConfigController`类，通过修改`config_wifi_connected_mac_randomization_supported`设置为`false`并实现初始化时的修改操作。

1、写在前面，为什么固定？因为在Android设备未连接网络时，会使用随机mac地址，如果想ota升级，不固定mac地址会导致风险。

2、控制wifi是否为随机mac地址功能的核心代码

frameworks/base/core/res/res/values/config.xml
packages/apps/Settings/src/com/android/settings/wifi/WifiConfigController.java

core/res/res/values/config.xml:751:    <bool translatable="false" name="config_wifi_connected_mac_randomization_supported">true</bool>

默认为ture 修改为false

grep一下如果有这几个文件，也需要改为false：

device/google/wahoo/overlay/frameworks/base/core/res/res/values/config.xml:370:    <bool name="config_wifi_connected_mac_randomization_supported">true</bool>
device/google/crosshatch/overlay/frameworks/base/core/res/res/values/config.xml:449:    <bool name="config_wifi_connected_mac_randomization_supported">true</bool>
device/google/bonito/overlay/frameworks/base/core/res/res/values/config.xml:412:    <bool name="config_wifi_connected_mac_randomization_supported">true</bool>

3、在初始化的时候进行修改
