如何在AOSP构建中设置默认属性? [英] How do I set the default properties in an AOSP build?

问题描述

在自定义AOSP版本中，我可以在哪里更改默认的Android设备属性?

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

例如:

• GPS-开启；
• 同步-开启；
• 亮度-自动；
• 蓝牙-OFF；
• WiFi-关闭；
• 声音-默认声音；
• 响铃时振动-OFF;

这些设置应在构建中定义，以便在加载构建后它们已经处于正确的状态.

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

是否存在所有设置的集中式文件/文件夹?还是从所有Android平台模块中自行收集设置的Settings应用程序?

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

推荐答案

我通常在两个主要位置检查默认值:

There are two main places I usually check for defaults:

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

和:

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

还值得检查设备目录中是否有覆盖原始文件的覆盖:

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

默认壁纸通常硬编码为:

Default wallpaper usually hardcoded to:

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

各种流的默认音量(int [] DEFAULT_STREAM_VOLUME):

Default volume levels for various streams(int[] DEFAULT_STREAM_VOLUME):

/frameworks/base/media/java/android/media/AudioSystem.java
