The invention provides a method for accelerating a multimedia scanning process in Android. According to the method, scanning workload is reduced by controlling the multimedia scanning range, and accordingly scanning time is reduced. According to the technical scheme, a storage volume which does not need multimedia scanning is determined in advance according to special purposes and other characteristics of outside storage volumes, and multimedia scanning is not carried out on the storage volume after a Media Provider receives broadcasts mounted on the storage volume; as for a storage volume needing scanning, directories which do not need media scanning in a first-level subdirectory are determined in advance, particularly the directories which contain a large number of files but do not contain multimedia files; when media scanning is carried out on the storage volume, the first-level storage subdirectory which does not need to be scanned is skipped. By means of the method, medium scanning time can be effectively shortened.
