Description
Technical Field
The invention relates to the field of android systems, in particular to a method for copying and rewriting an android system through USB storage equipment.
Background
The Android term is used to mean a "robot" and is also the name of the Linux platform-based open source mobile phone operating system announced by Google in 2007, 11 and 5, and the platform is composed of an operating system, middleware, a user interface and application software. The Android system architecture is the same as the operating system, and a layered architecture is adopted. From the architecture diagram, the Android is divided into four layers, namely an application program layer, an application program framework layer, a system operation library layer and a Linux kernel layer from a high layer to a low layer. Android is released with a series of core application packages including clients, SMS messages, calendars, maps, browsers, contact management programs, etc. All applications are written in the JAVA language. Developers may also have full access to the API framework used by the core application. The architectural design of the application simplifies the reuse of components, any one application can publish its function blocks and any other application can use its published function blocks. Also, the application reuse mechanism allows a user to easily replace program components. Android contains a number of C/C + + libraries that can be used by different components in the Android system. They provide services to developers through the Android application framework.
This application mainly solves two problems: 1. when the original software package of the android device is lost or the software version number is unknown, the software in the android device is copied to one or more other devices. 2. And when an upgrade package, a computer or a burning tool is not available on hand, the software of one android device is synchronized to be the same as that of another device. In order to overcome the defects of the prior art, a method for copying and rewriting the android system through the USB storage device needs to be designed.
Disclosure of Invention
in order to overcome the defects in the prior art, a method for copying and rewriting the android system through the USB storage device is provided.
The invention is realized by the following scheme:
A method of copying and rewriting an android system via a USB storage device, the method comprising the steps of:
Firstly, normally starting an android system, checking application starting of a USB storage device, and starting monitoring whether the USB storage device is inserted;
secondly, after the USB storage equipment is checked, whether the USB storage equipment has the starting file or not is checked, if the USB storage equipment does not have the starting file, the step one is returned, and the insertion of other USB storage equipment is continuously monitored; if the starting file is checked, analyzing the file, and judging whether a copying mode or a pasting mode is to be carried out;
if the mode is the copy mode, acquiring the size of system software and the space size of the USB storage equipment, and if the size of the system software is larger than the space size of the USB storage equipment, returning to the step one, and continuously monitoring the insertion of other USB storage equipment; if the size of the system software is smaller than the storage space of the USB storage device, executing a command to copy the system software into the USB storage device, modifying the starting file into a paste mode, and writing chip information into the starting file;
if the mode is the paste mode, chip information in the starting file is analyzed and compared with chip information read from the android device, if the mode is the same platform, a flag bit to be pasted is written into a flash (partition), and the system is restarted; if the platform is not the same, the USB storage device cannot be pasted, otherwise, the pasting system has problems, and the step I is returned to, and the insertion of other USB storage devices is continuously monitored;
Step four, if the system is restarted, entering u-boot, reading the flag bit by the u-boot, and if the flag bit is to be pasted, starting recovery in the USB storage device; if the flag bit is not pasted, returning to the step one, and continuously monitoring the insertion of other USB storage equipment;
and sixthly, reading the flag bit after recovery in the USB storage device is started, starting a pasting process to write the software in the USB storage device back to the system if the flag bit is pasted, restarting the system, and entering a new software system.
in step three, the system software size includes the entire partition plus recovery single partition.
in step three, the executed commands are assembled from dd commands.
in step six, the paste flow is integrated by dd commands.
the invention has the beneficial effects that:
The invention relates to a method for copying and rewriting an android system through a USB storage device, which solves the problem that software in the android device is copied to another device or devices under the condition that an original software package of the android device is lost or the version number of the software is unknown. The problem that the software of one android device is required to be synchronized into the same software as another device under the condition that an upgrade package, a computer or a burning tool is not available at hand is solved.
Detailed Description
The following further illustrates preferred embodiments of the invention:
A method of copying and rewriting an android system via a USB storage device, the method comprising the steps of:
firstly, normally starting an android system, checking application starting of a USB storage device, and starting monitoring whether the USB storage device is inserted;
secondly, after the USB storage equipment is checked, whether the USB storage equipment has the starting file or not is checked, if the USB storage equipment does not have the starting file, the step one is returned, and the insertion of other USB storage equipment is continuously monitored; if the starting file is checked, analyzing the file, and judging whether a copying mode or a pasting mode is to be carried out;
if the system software is in the copy mode, acquiring the size of the system software and the size of the space of the USB storage equipment, wherein the size of the system software comprises the whole partition and a recovery single partition, and returning to the step one if the size of the system software is larger than the space of the USB storage equipment, and continuously monitoring the insertion of other USB storage equipment; if the size of the system software is smaller than the storage space of the USB storage device, executing commands are copied into the USB storage device, the executed commands are combined by dd commands, the starting file is modified into a paste mode, and chip information is written into the starting file;
If the mode is the paste mode, chip information in the starting file is analyzed and compared with chip information read from the android device, if the mode is the same platform, a flag bit to be pasted is written into a flash (partition), and the system is restarted; if the platform is not the same, the USB storage device cannot be pasted, otherwise, the pasting system has problems, and the step I is returned to, and the insertion of other USB storage devices is continuously monitored;
