how to permanently enable bluetooth in the default settings

[Abhay Ghatpande]

Hello all,

We are building the AOSP image and would permanently like to enable some settings in the build because the user will not have access to the settings UI. (The device will be running a custom application always.)

For example BT connectivity should be always enabled, brightness settings, etc.

I am wondering where the default settings for a device are stored and how we can modify them.

Thanks for your help.

How about setting the default value to true to make bluetooth enable all the time?

You can do this by modifying Settings.

Hi Roger,

Can you give me some more details please? Modify which settings? Which files are they defined in? Remember that I wan to build Android with the settings enabled, I cannot use the Android settings UI. Or are you suggesting to enable the settings in my app using the Android settings API?

Thanks,

Abhay

Hi,

IMHO, what you should do is find, where available, the default value
that is set in the settings database.
For instance, the default value for bluetooth enablement can be found in
frameworks/base/packages/SettingsProvider/res/values/defaults.xml:
<bool name="def_bluetooth_on">false</bool>

The "right" way to change that is by overriding the entry in the overlay
part of your device tree:
DEVICE_PACKAGE_OVERLAYS/frameworks/base/packages/SettingsProvider/res/values/defaults.xml

The brightness settings happens to be at the same place.

In the end, the overlay files should only contain the values you want to
override. The build system will take care of overriding the values you
override, while keeping the ones you don't touch.
