Example Embodiment

[0028] Example 1.

[0029] An android system, including the image file update.img; the image file update.img is packaged and generated by 5 sub-image files ramdisk.img, system.img, userdata.img, boot.img, and kernel.img. The packaging steps are as follows:

[0030] 1) Provide a packaging module. The packaging module reads 5 sub-mirror files, and processes the 5 sub-mirror files to generate an intermediate image file _update.img. The header file of the intermediate image file includes the logo of each sub-mirror file Bit and length size information;

[0031] 2) The intermediate image file _update.img is packaged again to generate the image file update.img of the android system. The header file of the image file update.img includes the flag bit and length information of the intermediate image file, and the startup code Location and size.

[0032] Since the mirror file of the android system can be packaged and generated by 5 sub-mirror files, the mirror file can be unpacked in reverse t...

Example Embodiment

[0039] Example 2.

[0040] A custom tailoring method for android system, the method includes the following steps:

[0041] 1) Provide an unpacking module to unpack the image file update.img of the android system, and unpack to generate 5 target image files: ramdisk.img, system.img, userdata.img, boot.img, kernel.img file;

[0042] 2) Unpack at least one of the 5 target image files again to generate the corresponding public module;

[0043] 3) Modify the public module;

[0044] 4) Provide a packaging module, package the modified public module, and generate the corresponding target image file;

[0045] 5). Pack the 5 target image files to generate the intermediate image file _update.img;

[0046] 6) Pack and process the intermediate image file _update.img to generate the image file update.img of the android system.

[0047] Further, when performing step 1), the unpacking process includes the following steps:

[0048] a) The image file of the android system is update.img; read the header file...

Abstract

The invention relates to an android system and a customized tailoring method thereof. The android system comprises a mirror image file update.img, wherein the mirror image file update.img is generated by a mirror image sub-file ramdisk.img, a mirror image sub-file system.img, a mirror image sub-file userdata.img, a mirror image sub-file boot.img and a mirror image sub-file kernel.img in a packed mode. The customized tailoring method of the android system comprises the steps that the mirror image file update.img of the android system is unpacked; a corresponding common module is generated; the common model is modified; a packing module is provided, and the modified common module is packed until mirror image files are produced. The specific android system, the packing module and an unpacking module are adopted, and therefore the android system can be decomposed conveniently, and modification is conducted conveniently.

Description

technical field [0001] The invention relates to the technical field of software operating systems, in particular to an android system and a custom tailoring method thereof. Background technique [0002] At present, andorid has become the most popular mobile platform operating system, which is widely used in mobile phones, tablets and other devices. More and more manufacturers have launched their own android devices one after another. These devices are dazzling and have different functions. With such fierce competition, it is the best choice for each manufacturer to modify, tailor, optimize performance, refine functions, and maintain differences in native Android. Therefore, the demand for customization by manufacturers will continue to explode. [0003] Traditional android customization is to modify at the source code level, then compile and package, and finally test, and so on. Because the size of the android code is very large, the required compilation time is not short. ...
