This XML defines a list of UIDs for OEMs to register as shared UIDs. They will be registered at the
start of the system, which allows OEMs to create services with these UIDs. The range of these UIDs
must be in the OEM reserved range.

OEM must provide a preloaded app that is installed at boot time to retain the newly registered UID
by adding a android:sharedUserId tag in the manifest of the preloaded app, with the value of the tag
set to the name of the UID defined in this config file. Otherwise, the uid will be cleared at the
end of the boot and this config file will take no effect.

- The "name" XML attribute refers to the name of the shared UID. It must start with "android.uid.".
- The "uid" XML attribute refers to the value of the shared UID. It must be in range [2900, 2999].

Example usage
    <oem-defined-uid name="android.uid.vendordata" uid="2918"/>
    Indicates that a shared UID named "android.uid.vendordata" will be added to the system with the
    UID of 2918.
