Problems solved by technology

Because the future cannot be predicted, a large enough space must be reserved for pre-installed applications
[0004] There are generally two existing solutions. One is to reserve a large enough system partition, which will most likely waste storage space.
The other is to divide a separate partition to store preset applications, but it cannot solve the problem of waste of storage space

Embodiment Construction

[0040] It should be noted that the main partitions of the Android system include:

[0041] Modem partition, bootloader partition, boot partition, recovery partition, system partition and data partition, wherein the system partition and data partition are the system partition and data partition mentioned in the claims

[0042] 1. Modem partition: To realize the necessary communication functions of the mobile phone, what everyone usually flashes RADIO is to flash the modem partition, this part is not fixed in all adapted ROMs, otherwise it will cause unstable calls;

[0043] 2. Bootloader partition: Mainly perform hardware detection to ensure that the hardware can work normally, and then copy the secondarystage bootloader to the memory (RAM) to start execution.

[0044] It will also perform some hardware initialization work, obtain memory size information, etc., and then enter a certain startup mode according to the user's keystrokes. For example, as we all know, through the co...

Abstract

The invention discloses an Android system storage space structure construction method and device and a construction structure thereof, and the method comprises the steps: building a first storage directory in a data partition, and the first storage directory being used for storing a preset application; then, the preset application in the first storage directory being in soft link with the second storage directory under the system partition, so that the system can identify the preset application stored in the first storage directory as the system application; setting the attribute and authorityof the first storage directory to ensure the storage security of the first storage directory; and modifying a mirror image packaging process, an upgrading mode and a deleting mode when factory settings are restored, and ensuring that the preset application in the first storage directory normally runs as the preset application originally stored in the system partition. When the preset applicationstored in the first storage directory is upgraded, the storage space of the data partition is occupied, storage of other data in the data partition is not affected, it is guaranteed that the storage space used for storing the preset application is large enough, and it is guaranteed that the storage space is not wasted.

Description

technical field [0001] The present invention relates to the field of system storage, in particular, to a construction method, device and construction structure of an Android system storage space structure. Background technique [0002] The Android system divides the entire storage space into multiple partitions, and each partition stores specific content. Among them, the system partition is used to store the applications and data preset by the system. This partition is read-only when the system is running and cannot be modified. Moreover, the size of the partition is fixed during system design and cannot be expanded. This makes it impossible for subsequent applications to be preset because the system partition is full. The partitioning of Android determines the size of the partition when designing a product, and the partitioning cannot be modified in the subsequent upgrade process, otherwise the system will be damaged. [0003] When a product is updated and upgraded in the...
