framework层获取属性
frameworks\base\packages\SettingsProvider\src\com\android\providers\settings\DatabaseHelper.java
注意事项:某些路径下的配置可能会修改掉一些默认属性
1、frameworks\base\core\res\res\values\config.xml
2、device\rockchip\common\overlay\frameworks\base\packages\SettingsProvider\res\values\defaults.xml
3、device\rockchip\rkXXXXXX\overlay\frameworks\base\core\res\res\values\config.xml
设置媒体最大音量
在device\rockchip\rk356x\device.mk 或者其他mk文件中 配置
ro.config.media_vol_default=15
原因:AudioService 会获取该属性进行媒体音量设置
查看系统相关属性
adb shell settings list system
