android default setting

출처 :https://stackoverflow.com/questions/16770639/how-do-i-set-the-default-properties-in-an-aosp-build

Where can I change the default Android device properties in my custom AOSP build?

For example:

• GPS - ON;
• Sync - ON;
• Brightness - AUTO;
• Bluetooth - OFF;
• WiFi - OFF;
• Sound - default sound;
• Vibrate when ring - OFF;

These settings should be defined in the build so they are already in their correct state once build is loaded.

Is there a centralized file/folder for all the settings? Or a Settings application that gathers by itself settings from all Android platform modules?

There are two main places I usually check for defaults:

/frameworks/base/packages/SettingsProvider/res/values/defaults.xml

and:

/frameworks/base/core/res/res/values/config.xml

Its also worth checking the device directory for overlays which just override the original files:

/device/<company-name>/<product-name>/overlay/frameworks/base/core/res/res/values/config.xml

Default wallpaper usually hardcoded to:

/frameworks/base/core/res/res/drawable-nodpi/default_wallpaper.jpg
