Problems solved by technology

[0003] In practical applications, the content used is often part of the functions in the DEX file. However, since DEX2oat is a full compilation method, when the DEX file is large and dynamically loaded in the main thread, it may be due to compilation. ANR (Application Not Responding, program unresponsive) caused by too long time

Abstract

The invention discloses a file dynamic loading method and device, relates to the technical field of computers, and mainly aims to improve the dynamic loading efficiency of the file. According to the main technical scheme, the method comprises: loading a program file in a preset virtual machine, the preset virtual machine being used for loading an original program file, and code compiling does notneed to be conducted on the original program file; and constructing a program file object by analyzing the information in the program file. The method and the device are mainly used for dynamically loading the program file.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method and device for dynamically loading files. Background technique [0002] With the popularization of smart devices, the application programs in the smart devices are becoming more and more abundant, often including multiple small programs in one application program, and to start these small programs, it is necessary to dynamically load the corresponding startup files. In the Android system, the class loader DEXClassLoader is used to support dynamic loading of DEX files. The strategy it adopts when loading DEX files is to call DEXFile_openDEXFileNative by loading DEX files. In DEXFile_openDEXFileNative, it will call OpenDEXFilesFromOat to construct DEXFile objects. The process will execute DEX2oat to compile DEX files into oat files, that is, convert java code to binary machine code, and this compilation process is very time-consuming. [0003] In practical applications,...
