5.1之后settings.db改变存储位置

转:https://blog.youkuaiyun.com/kv110/article/details/51520207

Android L (5.1)及以前的版本

Settings参数保存在 /data/data/com.android.providers.settings/databases/settings.db里,里面有三个表global, system, secure. 

通常这样查看数据

adb shell sqlite3 data/data/com.android.providers.settings/databases/settings.db "select * from secure"

或者adb pull settings.db到本地,然后用sqlite expert打开即可。

 

Android M (6.0)开始出现变化

不同用户放不同的路径下,如果没有创建新用户,则在/data/system/users/0下

settings_global.xml, settings_system.xml,  settings_secure.xml 

 

直接修改例子

adb shell settings get global captive_portal_server

adb shell settings put global captive_portal_server 0
