Are you the developer of the app or do you have access to the developer? I believe what you may be looking for is Managed Configurations but the app would have to be built to support them.

Hi Matt

I am the developer but this simple enterprise app doesn't support settings in that way.  I can add them into the build as defaults and deploy a new version with a config update, but I was hoping that they were exposed somehow.  I would imagine they are protected within Android to prevent a rogue app from say writing to another's config and forcing a visit to a virus site.

That's exactly right. Managed Configurations however are a mechanism through which you can expose the kind of settings that you do not want to have manually set on each individual device. I would strongly recommend you look into them:

Hi David,

What is/are the brand(s) of your devices?  Are you using Android Enterprise or Android plus device agents?

How did you get the syntax of the command

  writeprivateprofstring <myAppName> BaseURI http://api.myAppDomain.com:8044/Api

Did you grant the required app permission(s) for your MobiControl device agent?  What are the version and build numbers of your device agent?

Thank you Raymond!  I believe though that mobicontrol does not have access to my settings which I guess is good, as I don't want other apps able to tamper with my apps private settings.

>> DMA  I have used it for other things.  I was hopeful but incorrect that it can affect my installed app.

What are the version and build numbers of your device agent? 14.0 build 1579.
