Embodiment Construction

[0036] The specific implementation of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the implementation and protection of the present invention are not limited thereto.

[0037] figure 1It shows the overall architecture of Android startup acceleration, which mainly includes:

[0038] 1. To achieve Android startup acceleration, change the BLCR dynamic loadable kernel module.

[0039] 2. Changes to BLCR's dynamic link library based on the Android platform.

[0040] 3. The addition of the bionic thread library function interface that supports BLCR technology.

[0041] 4. Changes to the Android startup execution process.

[0042] details as follows:

[0043] In the figure, BLCR technology can dynamically load the kernel module, which mainly transplants the dynamic loading kernel module of BLCR technology to the ARM-based platform. BLCR dynamic loading module is the core of BLCR kernel-level stand-alone checkp...

Abstract

The invention provides an ARM (Advanced RISC Machine) platform based Android startup acceleration method. By using the technology, the Android startup procedure is accelerated, the BLCR (Berkeley Lab Checkpoint/Restart) technology is adopted to perform breakpoint settings on the more time-consuming pre-loaded class and pre-loaded resource procedure process of a Zygote process in the Android startup procedure, then the current status and information of the process are stored into the next image file when the process is started up to execute breakpoints, and the process is directly started up from the image file when being started up at the next time, so that the time-consuming pre-loaded class and pre-loaded resource process is skipped to achieve the purpose of accelerating startup. Through the Android acceleration realized by the BLCR technology, the startup time of Android is shortened to 13 seconds, the startup speed of Android is increased by nearly 30% to 40%, and the method has no effect on the subsequent performance of Android.

Description

technical field [0001] The invention belongs to the technical field of computer operating systems, and in particular provides a method for accelerating Android startup on an ARM platform. Background technique [0002] Android startup acceleration has attracted more and more attention in recent years. Mainly due to the massive popularity of Android devices. Moreover, compared to mobile phones that are rarely turned off, other smart devices such as tablet computers are becoming more and more popular, and these devices need to be turned on and off frequently compared with mobile phones, so their startup speed directly affects the user experience and is also the key to judging the product. An important criterion for the quality of [0003] Android startup optimization has always been a very popular research field, and now the industry's demand for fast startup of Android startup is becoming more and more urgent. There are a lot of people both at home and abroad to carry out t...
