Embodiment 1

[0026] Please refer to figure 1 , figure 1 It is a flow chart of a preferred embodiment of the Android system-based memory expansion method of the present invention. Such as figure 1 As shown, the memory expansion method provided by the embodiment of the present invention includes the following steps:

[0027] Step S101, connect the data files and cache files under the system data partition to the corresponding files under the backup folder, and save them in the backup folder, and reconnect the data files and the cache files to the memory card on the file corresponding to the root directory.

[0028] The purpose of the embodiment of the present invention is to realize the installation of application programs on the external memory card of the Android system without user intervention. For this reason, the boot process is modified in this step, so that the Android system can establish a file structure that can meet the above-mentioned purpose. Good file connection relationsh...

Embodiment 2

[0056] See Figure 5 , Figure 5 It is a structural block diagram of a preferred embodiment of the Android system-based memory expansion device of the present invention. Such as Figure 5 As shown, a structural block diagram of an Android system-based memory expansion device provided by Embodiment 2 of the present invention, for convenience of description, only shows the parts related to the embodiment of the present invention.

[0057] The memory expansion device provided in this embodiment includes:

[0058] The system starts the connection unit 501, which is used to connect the data files and cache files under the system data partition to the corresponding files under the backup folder, and save them in the backup folder, and connect the data files and the cache files to the backup folder. Reconnect to the file corresponding to the root directory of the memory card;

[0059] A file connection unit 502, configured to connect the data files and cache files in the root dir...

Embodiment 3

[0080] Embodiment 3 of the present invention also provides an Android system terminal, and the terminal includes the memory expansion device based on the Android system as described in Embodiment 2. For example, the terminal can be a smart phone, MID, PAD, etc., as long as the application-related specific files (including data files and cache files) under the Android system data partition are connected to the corresponding files of the memory card, and the The boot process of the Android system and the PackageInstaller strategy enable users to install third-party applications on the external memory card without additional operations. Terminal devices using the above methods are all within the protection scope of the present invention.

[0081] Through the memory expansion method, device and terminal equipment based on the Android system provided by the above three embodiments of the present invention, users can make full use of the storage space on the terminal equipment, and s...

Abstract

The invention discloses a memory expanding method, a device and a terminal based on an Android system. The method comprises the steps of connecting a data file and a cache file under a system data partition with a corresponding file under a backup folder, storing into the backup folder, and reconnecting the data file and the cache file with a corresponding file of a memory card root directory; connecting the data file with the cache file in the memory card root directory or the backup folder into a corresponding file under the system data partition according to the plug-pull state of a memory card; when the memory card is at the mount state, carrying out dynamic switch on the data file and the cache file in the system data partition and the memory card, and at the same time, copying file data generated while installing an application program into a directory corresponding to the memory card root directory. With the adoption of the method, the device and the terminal, the purposes that a user objective installation program is installed into a memory card when the memory card is available, and the expansion of the system data partition under the Android operation is realized.

Description

technical field [0001] The invention relates to the technical field of electronic equipment with memory, in particular to a memory expansion method, device and terminal equipment based on an Android system. Background technique [0002] The Android operating system is an open source operating system based on Linux, which is currently widely used in various terminal devices, such as mobile phones, MIDs, PADs, and so on. At present, terminal devices based on the Android system generally have insufficient built-in ROM space, so that users cannot install a large number of required APK applications as needed; at the same time, the current applications adapted to the Android operating system occupy a relatively large capacity, especially game applications. Basically, due to the large third-party Lib library and audio and video resource files, the size of each game application often takes up tens of Mbytes of space, so it cannot meet the objective and actual needs of users. In add...
