Embodiment 1

[0021] Embodiment 1: a kind of Android-based operating system quick-start method disclosed in this embodiment includes a backup process and a quick-start process, and the overall flow chart of the program is as follows figure 2 shown.

[0022] The backup procedure is as follows image 3 shown, including steps:

[0023] Step 101: Start the device with the Android operating system installed, enter the boot program, then automatically load and start the Android operating system by the boot program, and enter the user interface program of the Android operating system;

[0024] Step 102: When the Android operating system is running after entering the user interface program, the user switches the Android operating system from the normal operating mode to the system backup mode.

[0025] In this step, the standard operating mode of the Android operating system is referred to as the normal operating mode, and the operating mode during system backup is referred to as the system back...

Embodiment 2

[0062] Embodiment 2: In order to further improve the startup speed of the Android operating system, a clipping process to the Android operating system can also be set before the backup process on the basis of embodiment 1, and only the user interface that can enter the user interface when the boot process is kept is reserved by the clipping process. The minimum number of modules necessary for the operating system results in a streamlined Android operating system.

[0063] Since the full Android operating system such as figure 1 As shown, there are five layers including the Linux kernel, native service layer, Dalvik virtual machine, android service layer (android service) and application layer. , Dalvik virtual machine, android service layer and application program layer, among which the local service layer and the android service layer have more than 60 modules, so the normal startup process is slow, and it takes about 1 minute from booting to entering the user interface.

Abstract

The invention discloses a quick operation system start-up method based on Android. The quick operation system start-up method comprises a backup process and a quick start-up process. The backup process comprises the following steps: entering a user interface program of an Android operation system; switching the Android operation system from a common operation mode to a system backup mode by a user; generating a quick start-up memory image; and backing up the quick start-up memory image in an external memory according to a pre-defined data structure for quickly starting up an image format. The quick start-up process comprises the following steps: reading the data structure for quickly starting up the image format from the external memory after the initialization of basic hardware apparatuses are completed by a boot program; gradually copying the quick start-up memory images from the external memory into the memory by the boot program by taking each memory page as a unit if entering the quick start-up model; and recovering the quick start-up memory images of the above steps by the boot program, and entering the user interface program of the Android operation system. The method provided by the invention has the beneficial effect that the start-up time of the Android operation system can be shortened.

Description

technical field [0001] The invention relates to an operating system quick start technology, in particular to an Android-based operating system quick start method and device. Background technique [0002] Android is an open source mobile phone operating system based on the Linux platform announced by Google on November 5, 2007. The platform consists of the Linux operating system kernel, dalvik virtual machine, support library, application framework and application programs. Due to its good openness and powerful functions, the current Android operating system is not only widely used in battery-powered embedded devices such as mobile phones, but also gradually applied to devices and products that use AC power such as digital TVs. [0003] The startup process of the Android operating system is as follows: figure 1 As shown, the startup process successively includes bootloader, Linux kernel, local service (native service), dalvik virtual machine, Android service (android service...
