Problems solved by technology

[0003] The purpose of the present invention is to provide a quick start method based on the android system after upgrading, which is used to solve the problem of the system and application after flashing the U disk in the prior art and needs to be converted into a bytecode suitable for the platform through the cross-platform virtual machine of the android system Problems with long conversion times

Embodiment 1

[0022] combined with figure 1 As shown, a quick start method based on the android system after upgrading,

[0023] A1. Write the target code (unoptimized) generated by the compilation of the android system into the terminal platform, and wait for the completion of the optimized section code of the android system.

[0024] A2. Restart the terminal platform to enter Recovery mode, and mount the U disk.

[0025] A3. Through the virtual logical device node under recovery, export and download all the generated bytecode data to the U disk. Specifically, read the first block data of the node, compress the data through gzip, and write it to the U disk file; check whether there is the next block data under the node, if there is, continue to read and copy One block data, and continue to execute the compression command to write the U disk image file cyclically, until all the block files under the node have been written, and complete the export of all bytecode data (in the form of img i...

Embodiment 2

[0030] A method for quickly starting after upgrading based on the android system, specifically comprising:

[0031] B1. Pack the data of each logical partition generated by the compilation of the android system into a U disk upgrade file, and flash the upgrade file to the TV terminal platform through the U disk, and confirm that the system completes the bytecode optimization process of the hardware platform through the log information .

[0032] B2. Debug tooling and tools through the serial port, connect to the TV terminal platform, check whether the bytecode optimization data in the data / dalvik-cache file directory is complete, and then restart the system through the serial port command reboot Recovery and force it to enter the Recovery mode. And in the Recovery system, create a mount directory and mount the U disk through mkdir.

[0033] B3, under Recovery, only export and download all the data of the single logical partition to the U disk through the mapping of the virtua...

Abstract

The invention discloses a quick boot method after upgrade based on an android system. The method comprises the following steps: writing a mirror image file compiled by an android system into a terminal; restarting the terminal to enter the Recovery mode and mounting the USB disk; in a Recovery mode, generating the block data of the virtual logical device node into bytecode data and writing into Udisk; exporting the bytecode data as an img mirror file and replacing the image file compiled by an android system; again through the compilation server, carrying out U disk upgrade file packaging, generating a U disk brusher program brushing machine. In a Recovery mode, the bytecode data generated by the system run is exported, so the bytecode data can be downloaded precisely with high efficiencyand safety. The new upgrade file of U disk is made and generated by replacing the img image file and re-building the upgrade file. After the upgrade of the brush program, the system bytecode optimization generation is not needed again, and the fast startup after the upgrade of U disk is greatly improved.

Description

technical field [0001] The invention relates to the technical field of smart televisions, in particular to a quick start method after upgrading based on an android system. Background technique [0002] With the overall stable growth of the Android smart TV market and the update and iteration of software functions in recent years, the method of flashing the U disk is becoming more and more popular and the flashing package is also getting larger and larger. At present, flashing only flashes the system and applications into the smart platform terminal, and then converts it into another format odex (byte code) suitable for the platform through dexopt through the cross-platform virtual machine dalvik of the android system (related to the specific hardware platform), and exists / data / dalvik-cache, and conversion and storage account for more than 70% of the entire flashing time. For this reason, it is particularly important to optimize the bytecode conversion time to achieve fast ...
