there is the option to host ADBMobile Json configurations also on a remote server. In Adobe Appmeasurement SDK documentation there is an example showing DTM as a delivery source for the config file (see below).
How do I set up DTM to deliver these Json configuration files?
Which version of the SDK are you using? If you are on 4.2 or higher it's automatically included in the file downloaded from Mobile Services. The file can be downloaded by going to mobilemarketing.adobe.com (or using Mobile Services in the Analytics/Marketing Cloud left side menu) > Manage App Settings > at the bottom of the page click on 'Config File'.
