解决LineageOS提示网络受限问题

问题原因
由于 LineageOS 源码里默认是使用 google captive连接验证服务,所以国内会一直提示网络受限,但是实际上是可以访问网络的。
要解决这个问题可以通过把 captive_portal_https_url 改为国内的就好了,比如用MIUI的。
更换 captive 连接验证服务器
1. 通过 adb 修改
adb shell settings put global captive_portal_https_url https://connect.rom.miui.com/generate_204
adb shell settings put global captive_portal_http_url http://connect.rom.miui.com/generate_204
2. 修改源码
编辑 packages/modules/NetworkStack/res/values/config.xml
<!-- HTTP URL for network validation, to use for detecting captive portals. -->
<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. -->
<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. -->
<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>
修改如下
<!-- HTTP URL for network validation, to use for detecting captive portals. -->
<string name="default_captive_portal_http_url" translatable="false">https://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>
<!-- List of fallback URLs to use for detecting captive portals. -->
<string-array name="default_captive_portal_fallback_urls" translatable="false">
<item>https://connect.rom.miui.com/generate_204</item>
<item>https://connect.rom.miui.com/generate_204</item>
</string-array>
当时间不准时修改使用(修改为阿里云)
1. 通过adb修改
adb shell settings put global ntp_server ntp.aliyun.com
2. 修改源码
编辑 device/vendor/device/gps/etc/gps.conf(vendor和device是对应的厂家和设备)
#NTP server
NTP_SERVER=time.izatcloud.net
修改如下
#NTP server
NTP_SERVER=ntp.aliyun.com
