Problems solved by technology

The native system provides comprehensive functions to meet the needs of different platforms. Only SystemServer has started nearly 50 services, but in fact a large part of the services do not need to exist on specific hardware platforms.

Embodiment Construction

[0055] Such as Figure 5 As shown, it is the implementation method of Android system service plug-in. The specific steps of the implementation process are the results summarized after analyzing and combing the Android native system startup process and system services one by one:

[0056] Step S501, Android service plug-in starts.

[0057] In step S502, init.rc supports process startup configuration. Add the description of the startup parameters of the process in init.rc to support the configuration of the startup of the process. Specifically, it is necessary to modify the parsing part of the configuration file in init.c.

[0058] In step S503, the configuration of Activity startup is supported in AndroidManifest.xml. Some startup services in Android are started by receiving startup messages, so it is necessary to modify the parsing logic of the application package in PackageParser to support the configuration of service or component startup.

[0059] In step S504, the syst...

Abstract

The invention relates to the technical field of Android system construction on an embedded device, in particular to an implementation method for an Android system service plug-in. According to the implementation process, the method comprises the specific steps that the Android service plug-in is started; process initiation configuration is supported in a configuration file; assembly starting configuration is supported in the AndroidManifest.xml; a plug-in service loading frame is supported in the system core service process; default values and configuration files of services and processes are supported under a product catalogue; a depend rule between the services is defined; a configuration analysis module during system operating is programmed; the plug-in is carried out on related services during system support operating period debugging; the service plug-in is achieved and completed. Based on the optimization of an Android main force released version Android 4.4 in the current market, after the most compact system is started, the internal storage is reduced about 100 M, and 30% improvement is achieved in proportion. The system starting time is shortened by 2 s, and the 10% improvement is achieved.

Description

technical field [0001] The invention relates to the technical field of building an Android system on an embedded device, and more specifically, provides a method for customizing system services according to different product requirements, which can improve system performance while saving hardware resources. Background technique [0002] Since the release of the first version of Android, the fragmentation and compatibility of the system have been the problems that Google's engineers have been working hard to solve. After several version replacements, the current version has greatly improved both in terms of compatibility and stability. improvement. It is already compatible with products of different specifications for mobile phones and tablets, and the compatibility work for different types of devices has also been reflected in the latest version. But the problem that comes with it is that the huge service framework makes the system too bloated, takes up valuable hard disk s...
