Embodiment Construction

[0035] The present invention provides an Android system upgrade method and system for multi-partition external storage devices. In order to make the purpose, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] see figure 1 , which is a flow chart of the Android system upgrade method of the multi-partition external storage device of the present invention. As shown in the figure, the upgrade method includes the following steps in sequence:

[0037] S1. In the Android system, obtain the unique identification codes corresponding to the partitions of all external storage devices mounted locally;

[0038] Specifically, the unique identification code uuid (Universally Unique Identifier unique identification code) refers to a number...

Abstract

The invention discloses an Android system upgrade method and system for multi-partition external storage devices, wherein the method includes: in the Android system, obtaining the unique identification codes corresponding to the partitions of all external storage devices mounted locally; and then finding the upgrade The package records the relative path of the upgrade package; then calls the system interface, writes the unique identification code and the relative path of the upgrade package into the recovery system; restarts and enters the recovery system, and finds out the location of the external storage device corresponding to the unique identification code partition, and mount it in the recovery system, obtain the upgrade package from the mounted storage device, and upgrade the Android system. It makes the multi-partition storage device used as a local upgrade package storage point for system upgrade, without being limited by the number of upgrade partitions and mount points, and improves the flexibility and scalability of Android system upgrade.

Description

technical field [0001] The invention relates to the technical field of Android system upgrades, in particular to an Android system upgrade method and system for multi-partition external storage devices. Background technique [0002] In the field of Android system research, the system when the machine starts normally is called the Android system, and the system used when the machine is upgraded (that is, the Android system is upgraded) is called the recovery system. The Android system generally completes system recovery and upgrade through the recovery system, including restoring factory settings, OTA upgrades, patch upgrades, and firmware upgrades. [0003] Since the Android system was originally designed for mobile devices such as mobile phones, and the mobile phone itself has no external USB storage device, and the built-in SD card has only one partition, the existing upgrade method can be found in the partition of the external storage device. Upgrade the file and upgrade...
