A method for implementing an android operating environment based on a non-virtualized architecture

Abstract

The invention belongs to the field of computer basic software and relates to an Android running environment realization method based on a non-virtualized system architecture. According to the method,an Android running environment is constructed on an existing Linux kernel and recorded as xDroid, and an Android application framework and an Android running time library are migrated to a standard Linux kernel. The xDroid does not need the virtualization technology but stands from a basic library and a basic running mechanism provided by a desktop operating system kernel, an Android bottom running supporting library needed for Android application running is realized layer by layer from bottom to top, then efficient migration of the Android running time library is realized, and the Android running environment is realized on a desktop operating system platform. Compared with a virtualization-based technology, ecological complete fusion of desktop applications and Android applications is realized in a true sense through the xDroid, and the applications are high in starting speed and high in performance; and meanwhile realization is based on different platforms, so that cross-platform running is easy to realize.

Description

technical field [0001] The invention belongs to the field of computer basic software, and relates to a method for realizing an Android operating environment based on a non-virtualized architecture. Background technique [0002] According to StatCounter statistics, Android surpassed Microsoft Windows in March 2017 and became the most popular operating system on the Internet; the rapid development of the mobile Internet has also made mobile applications greatly surpass desktop applications in terms of quantity and traffic. This can be seen from the fact that the order volume of mobile applications on e-commerce platforms has far exceeded that of desktop applications; the popularity of mobile games has prompted a large number of gamers to no longer meet the constraints of small screens and low performance of mobile phones, and eagerly hope that mobile games can be high-quality. Capabilities run on desktop terminals. [0003] If Android applications can run smoothly on the dome...

Problems solved by technology

[0007] The virtual machine technology has the following problems: First, the emergence of Android emulators is closely related to games. Although it can support the running of Android applications, the focus of development is to meet the needs of game users, rather than general Android applications and development needs; The user's game environment mainly supports Windows and Mac platforms, but does not support Linux platforms, let alone domestic operating systems; third, it relies on CPU hardware virtualization technology, which cannot be supported by the current technical status of domestic CPUs (Phytium, Loongson, etc.); After the introduction of the virtual machine, the resource consumption is large, the freeze, the delay, the occasional system crash, and the lack of smoothness

[0010] The Android-x86 technology has the following problems: First, from a technical point of view, the current Androidx86, RemixOS, PhoenixOS, EmindOS / OPNENTHOS should all belong to the limited extension implementation based on AOSP, we collectively call it the Android-x86 technology system, although they are not a brand new Operating system, but compared with the domestic operating system that already has a certain foundation, it is a new top-down path, which also means that the original research and development work based on the domestic operating system and the Linux application system are all discarded, and it is necessary to start from scratch. Because these systems basically do not support Linux applications, this is not advisable

Third, from the perspective of external factors, although Google has not extended Android to the desktop, it is not without this technical strength (in fact, Android6. Stacked multi-window support), the reason why they did not do so is due to its strategic considerations. Once Chrome / ARC matures, it will inevitably hinder the development of Android desktops. It can be said that Android and Chrome / ARC are Google's mobile computing and The two sharp weapons of the Internet of Things ecology, the two can only promote each other, and cannot block each other

[0013] The Chrome / ARC technology has the following problems: First, Chrome / ARC is built on the Chrome browser and must rely on the Chrome browser. This technical system determines its poor performance and compatibility; second, Chrome / ARC is partly open source , the code is not fully mastered, which is inconsistent with the goal of independent controllability and localization

Third, there are some uncertain technical factors, such as how to adapt PC hardware, etc., which also makes it incompatible with some PC devices
