Method and device for picture loading based on Android system

Abstract

The invention discloses a method and a device for picture loading based on an Android system. The method includes: A, sending out an order of a picture loading task and initializing soft references of a stored picture; B, judging whether the picture to be displayed is stored in the soft references or not; C, if not, running a picture loading thread for loading, and if yes, directly performing the step F; D, if the memory is insufficient, automatically recovering the picture stored in the soft references until the memory is sufficient; E, storing the picture in the soft references when the picture to be displayed is loaded; and F, directly reading the picture to be displayed from the soft references and displaying the picture. Using the method and the device for picture loading based on the Android system can avoid repeated picture loading to realize rapid picture calling, dependence on the memory is reduced, the device can be operated smoothly in low-performance systems, and user experience can be enhanced.

Description

technical field [0001] The invention relates to the application field of the Android system, in particular to an Android system-based image loading method and image loading device. Background technique [0002] The Android system limits the maximum memory of each process to 16M. In some applications with many pictures, such as: picture browsing and online display of posters, the problem of out of memory (out of memory) is often encountered. At this time, The process of loading images is slow and the user experience is poor. [0003] In the prior art, one method is to solve this problem by increasing the maximum memory limit of the Android system for each process, but this solution requires sufficient memory hardware of the Android system; and in actual products, the system usually needs to run simultaneously Multiple applications that take up a large amount of memory can easily lead to insufficient system memory and slow running of the program. [0004] In addition, there ...

[0002] The Android system limits the maximum memory of each process to 16M. In some applications with many pictures, such as: picture browsing and online display of posters, the problem of out of memory (out of memory) is often encountered. At this time, The process of loading images is slow and the user experience is poor

[0003] In the prior art, one method is to solve this problem by increasing the maximum memory limit of the Android system for each process, but this solution requires sufficient memory hardware of the Android system; and in actual products, the system usually needs to run simultaneously Multiple applications that take up a large amount of memory can easily lead to insufficient system memory and slow running of the program

[0004] In addition, there is another way to release memory by continuously manually calling the java garbage collection mechanism. Since the thread performing garbage collection is a low-priority thread, in the life cycle of a Java program, it can only be used when the memory is free. Only when it has a chance to run, it cannot be enforced, so when the application actively calls, if the system is busy or does not meet the garbage collection conditions, the java garbage collection mechanism will not get a response, and the system still waits for a long time for the garbage collection program to run. It will cause memory overflow, so this method cannot fundamentally solve the problem
