Android Settings xml We have exported the Android Settings of a Device running Android 4.4.3
We want to use this settings.apk to make our own default build for my other android devices (same device, same Android Version). 
We would like to get deploy customized preferences for all devices and we think that is possible to compile this app again with our new preferences included. 

How can we deploy the same customized settings on a fleet of devices?

Device: Motorola TC70
What you want to achieve should be possible using adb backup (no root required):


Enable ADB USB mode on all devices (have to be done manually, AFAIK). 
On the pre-configured device perform an adb backup of -all or if you know it only the relevant system settings app (I think it should be com.android.providers.settings?).
(optional) Decrypt and decompress the crated backup using Android Backup Extractor. You can now extract and edit the data in the backup, removing unnecessary/unwanted settings. Afterwards recreate the backup file using the modified data.
On each device perform an adb restore using the created backup from step 2 or 3.
