Abstract

The present invention is applicable to the field of picture playback, and provides a picture preloading method and device. When a picture player or an audio and video player plays pictures, it triggers the acquisition of pictures that need to be preloaded; it is judged whether the resolution of the pictures exceeds the preset resolution threshold; if the resolution of the picture exceeds the resolution threshold, the compression factor is calculated according to the picture compression algorithm; the picture is compressed according to the compression factor, and the compressed picture is preloaded; thereby effectively preventing OOM is eliminated, which ensures the smooth playback of pictures and is more user-friendly.

Description

technical field [0001] The invention belongs to the field of picture playback, and in particular relates to a picture preloading method and device. Background technique [0002] At present, mobile terminals based on the Android (android) system are widely used in all aspects of life, for example, people use smart phones for communication, surfing the Internet and taking pictures every day. [0003] As we all know, the maximum memory allocated by the android system for each process is only 16M. If the application loads some resources that occupy memory, it will cause insufficient memory and an Out of Memory (OOM): especially, image players or audio and video playback When the player plays pictures, it needs to load pictures (including: the previous picture, the currently playing picture, and the pre-playing picture, etc.), where the previous picture and the currently playing picture are the loaded pictures, and the pre-playing pictures are the loaded pictures. The picture is...
