The invention discloses a resource access method of an Android system, and belongs to the technical field of a mobile system. The resource access method of the Android system aims at solving the technical problem that in the existing Android system, the security and the completeness of resources of a user can be threatened. The resource access method of the Android system comprises the following steps of: sequentially performing DAC (Discretionary Access Control) permission checking and MAC (Mandatory Access Control) permission checking on a resource accessing process; if the process passes the DAC permission checking and the MAC permission checking, obtaining a security label of the process and a security label of the resources; matching the security label of the process and the security label of the resources; and if the security label of the process and the security label of the resources are matched, allowing the process to access the resources.
