Method and device for application preloading

The invention provides a method and a device for application preloading, and belongs to the technical field of terminals. The method comprises: receiving a scene switching instruction, the scene switching instruction being used to indicate to switch to a second Activity from a first user switching Activity; pausing to process the first Activity; in the process of pausing to process the first Activity, reading a preloading multimedia resource list of the second Activity from local, based on idle computing resources, starting at least a thread to load multimedia resources in the preloading multimedia resource list of the second Activity to a global resource buffer pool. The method accelerates integrated execution speed, saves time consumed by actually using the multimedia resources, and improves application operation speed.
