The description of Test DPC:
Please note that this app is for development purposes only. It is NOT intended for production usages. The app should never be used with real data.
Test DPC is a sample device policy controller for use with Android Enterprise. It gives developers the ability to see how their app will behave in a managed context such as device owner or within a managed profile. Users can set up a work profile, enable work apps, set applications restrictions, manage security policies, and much more. The app also serves as an implementation reference for other DPCs.
