Patent attributes
An electronic device is disclosed that includes a memory storing a first application run based on a first sandbox environment and a processor connected with the memory. The memory stores instructions which, when executed, cause the processor to determine whether it is necessary to change a first user identifier (UID) for the first application in response to an application installation request requesting to update the first application to a second application, assign a second UID for the second application using a UID mapping resident program based on it being necessary to change the first UID, and construct a second sandbox environment for the second application to have the second UID and a resource included in the first sandbox environment.
