Android 10.0 11.0设置默认屏幕密度(density)

定制化开发中需要增加属性来保存默认屏幕密度density

1.首选就是要在SettingsProvider把默认值添加到数据库中
先在SettingsProvider的default.xml文件中配置display_density_forced的值
diff --git a/frameworks/base/packages/SettingsProvider/res/values/defaults.xml b/frameworks/base/packages/SettingsProvider/res/values/defaults.xml
