In some embodiments, the kernel program for processing the target application by adopting the native method in the step includes: the virtual machine calls the corresponding relation between a preset program and local simple native interfaces, and each local simple native interface is respectively associated with one native module; searching a local simple native interface corresponding to the core program according to the corresponding relation; and processing the core program through a native module (namely a native simple native method) corresponding to the native simple native interface.
The correspondence is shown in table 1 below:
| kernel program | native interface | native module | |
| Opening up a storage | native interface | 1 | |
| Accumulating data | native interface 2 | native Module 2 | |
| |
native interface 3 | native module 3 | |
| …… | native interface 4 | native Module 4 |

In table 1, the functions of the native modules are all implemented by the native C programming language, and the C programming languages corresponding to the native modules are stored in the chip ROM in a hard mask manner, so long as applications related to the functions of the native modules can be directly called, and thus, the basic file system is stored in the chip ROM in a hard mask manner, so that the method can be applied to any other application requiring storing a file structure.
To address this problem, in some embodiments, the method shown in fig. 1 further includes, after step S103: acquiring an application adjustment requirement, determining an application to be adjusted corresponding to the application adjustment requirement, and forwarding the application to the virtual machine; and the virtual machine adopts a hard patch address mapping mechanism and other byte code patch modes to adjust the outer layer program and the core program of the application to be adjusted. Aiming at different application requirements, the embodiment can realize fine adjustment of the bottom code through a byte code patching mechanism, support a hard patch address mapping mechanism, maximally support 8 address mapping patches, and more conveniently carry out code level fine adjustment aiming at more applications.
