AOSP ~ default attribute value

2022-06-25 02:47:00 【Nanke is cute】
In customized development , Some requirements need to be given a default state , For example, the application installation allows the installation of unknown sources , Enable Bluetooth by default , Turn on wifi, Sleep time , And so on .
In system framework/base/packages/SettingsProvider/res/values/ There is a defaults.xml file , It contains the configuration of the function attributes of most systems ,
<resources>
