Problems solved by technology

However, some larger applications, such as the Kay Rucker GPS navigation program, cannot be installed in the built-in user storage partition with a small space because of the large amount of data, so that the mobile phone cannot meet the needs of users.
And because of the mount point, the application cannot be installed on the external large-capacity expansion memory card

Embodiment 1

[0041] If the mobile phone user does not plug in a T card, the steps of the dynamic mounting method of the memory card are as follows:

[0042] Step S101, detect whether there is an external T card through the Linux virtual file system sysfs of the Android system;

[0043] The Linux2.6 kernel introduces the sysfs virtual file system, which can generate a hierarchical view containing all system hardware, which is an intuitive response to the actual device tree on the current system, and organizes the devices and buses connected to the system into a hierarchical file . The user space can easily read the relevant file information in sysfs to confirm whether there is an external memory card in the system.

[0044] Step S102, if the external T card is not set, then the mounting process is carried out according to the default method of android, and the second storage area of ​​the built-in memory card is mounted to the path that can run the application program;

[0045]In the Andr...

Embodiment 2

[0049] The mobile phone user plugs in a T card, then the dynamic mounting method of the memory card, the steps are as follows:

[0050] Step S201, detect whether there is an external T card through the Linux virtual file system sysfs of the Android system;

[0051] The Linux2.6 kernel introduces the sysfs virtual file system, which can generate a hierarchical view containing all system hardware, which is an intuitive response to the actual device tree on the current system, and organizes the devices and buses connected to the system into a hierarchical file . The user space can easily read the relevant file information in sysfs to confirm whether there is an external memory card in the system.

[0052] Step S202, the user's mobile phone inserts an external T card, and when the external T card is detected, the mounting path of the second storage area of ​​the built-in memory card and the external T card is exchanged;

[0053] In the Android system, Vold is a Linux daemon proc...

Abstract

The invention discloses a memory card of handheld equipment. Based on an Android system, the memory card comprises an internally-arranged memory card; the internally-arranged memory card is divided into a first storage region and a second storage region; the first storage region is an ROM (Read Only Memory); a system program and / or an application program of the handheld equipment are / is stored in the ROM; and the second storage region belongs to a user storage space, is mainly used for storing relative data for a user and can also be used for mounting the application program. A dynamic mounting method of the memory card is used for dynamically selecting mounting between the second storage region of the internally-arranged memory card and an externally-inserted T card. According to the memory card of handheld equipment, the mounting path of the second storage region of the internally-arranged memory card and the externally-inserted T card is replaced, so that the utilization efficiency of a cell phone is improved and the cost is saved.

Description

technical field [0001] The invention relates to a mobile terminal device, in particular to a memory card of a handheld device based on an Android system and a dynamic mounting method thereof. Background technique [0002] The native android system refers to the most original and pure Android system released by Google, which has not been modified by any third party (mobile phone manufacturers), and is the most perfect system in mobile phones. Because of open source, the same Android system has some smoothness and some lags. Now some mobile phone players no longer consider the hardware configuration of the mobile phone as long as it is native. Currently the best is Android4.0 Galaxy Nexus. [0003] Operating systems such as linux and unix manage everything in the system as files. In Windows, our common hardware devices, disk partitions, etc. are regarded as files in Linux and Unix. Access to devices and partitions is to read and write corresponding files. The mount point is...
