场景

一些非国产的rom包，比如：aosp，lineageOS，crdorid，PE，PixelOS等，在连接wifi 的时候，会显示一个感叹号，这就造成了一个情况，不能自动连接WIFI，无法自动WIFI调试。

解决方案

修改源码路径：packages/modules/NetworkStack/res/values/config.xml

源文本：

    <string name="default_captive_portal_http_url" translatable="false">http://connectivitycheck.gstatic.com/generate_204</string>
    <!-- HTTPS URL for network validation, to use for confirming internet connectivity. -->
    <!-- default_captive_portal_https_url is not configured as overlayable so
         OEMs that wish to change captive_portal_https_url configuration must
         do so via configuring runtime resource overlay to
         config_captive_portal_https_url and *NOT* by changing or overlaying
         this resource. It will break if the enforcement of overlayable starts.
         -->
    <string name="default_captive_portal_https_url" translatable="false">https://www.google.com/generate_204</string>

    <!-- List of fallback URLs to use for detecting captive portals. -->
    <!-- default_captive_portal_fallback_urls is not configured as overlayable
         so OEMs that wish to change captive_portal_fallback_urls configuration
         must do so via configuring runtime resource overlay to
         config_captive_portal_fallback_urls and *NOT* by changing or overlaying
         this resource. It will break if the enforcement of overlayable starts.
         -->
    <string-array name="default_captive_portal_fallback_urls" translatable="false">
        <item>http://www.google.com/gen_204</item>
        <item>http://play.googleapis.com/generate_204</item>
    </string-array>

修改后文本：

   <string name="default_captive_portal_http_url" translatable="false">http://connect.rom.miui.com/generate_204</string>
    <!-- HTTPS URL for network validation, to use for confirming internet connectivity. -->

    <string name="default_captive_portal_https_url" translatable="false">https://connect.rom.miui.com/generate_204</string>

         -->
    <string-array name="default_captive_portal_fallback_urls" translatable="false">
        <item>http://connect.rom.miui.com/gen_204</item>
        <item>http://connect.rom.miui.com/generate_204</item>
    </string-array>

就是把国外的地址，改成miui的就行。

接下来就可以开始重新编译，验证一下了，不过首次的时候，要选择离线激活才行。
