Android system formatting method and device based on DEX

Abstract

The invention discloses an Android system formatting method and device based on DEX, and the method comprises the steps: setting standard configuration for an MK file of a non-core application in an Android system according to a preset application division rule, and executing system compiling; according to the MK file of the non-core application subjected to system compiling, setting a filtering condition, and executing filtering operation on all the applications to obtain a filtered core application; and performing DEX processing on the core application according to a source code path of the Android system and a preset DEX processing function so as to complete formatting of the Android system. According to the method and the device, under the condition that user experience is considered, space redundancy and time redundancy are avoided, the method and the device are adaptive to customized equipment of the AOSP, and balance space and time.

Description

technical field [0001] The invention belongs to the technical field of mobile terminal systems, in particular to a DEX-based Android system formatting method and a device thereof. Background technique [0002] The Android system (Android) is a set of operating systems based on the Linux platform led and developed by Google and the Open Handheld Alliance, mainly suitable for mobile devices. With the use of the Android system, mobile devices sometimes need to be formatted and upgraded or restored to factory settings to improve the smooth operation of the mobile device. [0003] In the prior art, when the mobile device of the Android system is formatted and upgraded or the factory settings are restored, the system compilation link will perform DEX processing (DEX, full name DalvikVMexecutes, AndroidDalvik execution program) for all preset system applications, resulting in optimized files such as oat , leading to a significant increase in the size of the ROM package; or in the ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, when the mobile device of the Android system is formatted and upgraded or the factory settings are restored, the system compilation link will perform DEX processing (DEX, full name DalvikVMexecutes, AndroidDalvik execution program) for all preset system applications, resulting in optimized files such as oat , leading to a significant increase in the size of the ROM package; or in the format upgrade / restore to factory settings, the system performs DEX processing on the preset applications that have not been DEXed, but this will increase the time-consuming during the boot phase, and the above are not applicable Based on AOSP-based customized equipment

[0004] In order to solve problems such as increased ROM package space caused by DEX operations in the prior art, long boot time, and inability to support extended devices based on AOSP (full name AndroidOpenSourceProject), those skilled in the art have the motivation to develop a DEX processing based on the Android system. method
