Fetching vendor specific policy events and corresponding device feature mappings from a policy server at mobile device runtime of a managed application

A policy file and a mapping file are fetched from a policy server responsive to a defined event associated with execution of an application by a mobile device. The policy file contains policy events that define features of the mobile device that the application is allowed to access. The mapping file defines associations between the features of the mobile device and the policy events. The policy file and the mapping file are locally saved in a local memory of the mobile device. A policy evaluation request is received that identifies a feature of the mobile device that the application will invoke. A policy event associated with the feature is identified based on content of the mapping file. The policy event associated with the feature is obtained from the policy file. Whether the application is allowed to invoke the feature is controlled based on evaluating whether the policy event is satisfied.
