Alternative embodiments of the present disclosure are described in detail below with reference to the drawings.
As shown in fig. 1, according to a specific embodiment of the present disclosure, the present disclosure provides a method for simplifying an installation package so file.
The so file is in the form of an elf, which is relatively complex and only a brief description of the knowledge that needs to be used is provided here. From the standpoint of compilation, the so file is mainly composed of a plurality of sections (sections): some sections are internally represented by symbol tables (e.g.,. Dynsym), some sections are internally represented by codes (e.g.,. Text), some sections are internally represented by variables with initial values (e.g.,. Data), and some sections are internally represented by variables with no initial values or initial values of 0 (e.g.,. Bss). The function or variable defined in c/c++ source code will be present in the corresponding section of so (a function is typically. Text, a variable is typically. Data or. Bss), and if this function or variable is derived, it will also be present in the symbol table (typically. Dynsym).
Briefly introduced here is a symbol table, where a symbol table has a plurality of symbols, a symbol generally representing a function or a variable, and some symbols are implemented by the present so, called derived symbols; some symbols are native dependent, called import symbols. The simplification of the scheme mainly relates to the simplification of the section in the so file, in particular to a symbol table.
The generation process of the so file is briefly described as follows: the generation of one so file needs four stages of preprocessing, compiling, assembling and linking, wherein the preprocessing stage performs operations such as macro definition expansion, include content replacement and the like; compiling the c/c++ code into assembly code in a compiling stage; the assembly stage compiles the assembly code generated in the previous stage into a target file (.o); and in the linking stage, all input target files (.o), a static library (.a) and a dynamic library (.so) are subjected to static linking to obtain a final so file.
The method includes that firstly, a java native method is registered in a function JNI_OnLoad, and therefore only one derived function of the JNI_OnLoad is needed in so. Redundant information in the so file, i.e. information that has no effect on the operation of the so file, is then removed during the compiling and linking phase. Such information includes the following:
not all functions and all variables that are directly or indirectly referenced by jni_onload. Since the so file is dynamically linked, its derived variables and derived functions are used by the outside world, where the derived variables do not reference other functions or variables, the derived functions can be considered their entry points. For a variable (or function), if it is not derived and is not directly or indirectly referenced by any derived function, then the variable (or function) is redundant information and does not affect the execution of the so file after deletion. Since the present disclosure has ensured in the previous step that the target so only derives the jni_onload function, it only needs to consider if the variable or function is referenced by jni_onload.
The function or variable in the static library on which the target so depends is redundant information if the function or variable is not directly or indirectly led to by the lead-out function, and the operation of the so is not affected after the function or variable is deleted.
The method specifically comprises the following steps:
step S102: and establishing a link relation between the first function and the second function, wherein the first function operates in a first development language, and the second function operates in a second development language.
And registering the native method of the java class in the function JNI_OnLoad through the C code. The native method of Java is implemented by using a Java style export function for many applications, and a better way is to export jni_onload function, which is automatically called when the system loads the target so, and we register native s in this function. This has several benefits:
first, the function of Java style is not needed to be derived, so that the safety of application can be improved to a certain extent.
Secondly, if the signature of the corresponding java native method changes, the so generated by adopting a register native mode collapses during loading, and problems are found in advance; the derived function of Java style is adopted, and only the native method is first called to collapse.
Third, the size of so can be reduced in general.
Step S104: creating a source code file, wherein the file only comprises the second function.
Configuration is added indicating that there are only jni_onload functions that need to be exported.
First a file (assumed to be version. Script) is created in the engineering catalog, the contents of which are as follows:
step S106: and configuring the SO file export path to lead the SO file export path to point to the source code file.
If ndkBuild is used, then the following is added in application. Mk:
APP_LDFLAGS+＝-Wl,--version-script＝src/main/cpp/version.script
the src/main/cpp/version file should be replaced by the actual path of the version file above (path relative to application. Mk).
If a cmake is used, the following is added to the cmakelist.
set(CMAKE_SHARED_LINKER_FLAGS
"${CMAKE_SHARED_LINKER_FLAGS}-Wl,--version-script＝
${CMAKE_CURRENT_SOURCE_DIR}/version.script")
Here, the path of version, script is also replaced by the path of the real version, script file (cmake_shared_link_flags represents the directory where the current CMAKE lists, txt file is located).
After the configuration, the generated derivative function of so is only jni_onload.
Optionally, the linking stage further comprises the following steps: : and configuring the static library of the SO file, SO that the static library of the SO file only retains the dependent export function and export variable.
A configuration is added such that all derived symbols (including derived functions and derived variables) in the static library that are relied upon are no longer derived in the generated so.
If ndkBuild is used, then the following is added in application. Mk:
APP_LDFLAGS+＝-Wl,--exclude-libs,ALL
if a cmake is used, the following is added to the cmakelist.
set(CMAKE_SHARED_LINKER_FLAGS
"${CMAKE_SHARED_LINKER_FLAGS}-Wl,--exclude-libs,ALL")。
Optionally, the linking stage further comprises the following steps:
and configuring the link sections of the SO file in a first configuration mode or in a second configuration mode, and removing unused sections in the link sections.
If ndkBuild is used, then the following is added in application. Mk:
APP_LDFLAGS+＝-Wl,--gc-sections
if a cmake is used, the following is added to the cmakelist.
set(CMAKE_SHARED_LINKER_FLAGS
"${CMAKE_SHARED_LINKER_FLAGS}-Wl,--gc-sections")
The effect is as follows: if all members of a section are not used by functions or variables in the export table, then the section will not be present in the final so and can act on the static library of dependencies. With the above-mentioned flag, the final so volume is greatly reduced, but there may still be useless content: if only a portion of the members in a section are used, then the section is also retained.
Optionally, the method further comprises:
and configuring the functions and the variables of the SO file through a first configuration mode or a second configuration mode, SO that the functions and the variables are distributed into independent sections.
And adding configuration to ensure that functions and variables are distributed to independent sections.
If ndkBuild is used, then the following is added in application. Mk:
APP_CFLAGS+＝-ffunction-sections-fdata-sections
if a cmake is used, the following is added to the cmakelist.
set(CMAKE_C_FLAGS"${CMAKE_C_FLAGS}-ffunction-sections-fdata-sections")
set(CMAKE_CXX_FLAGS"${CMAKE_CXX_FLAGS}-ffunction-sections-fdata-sections")
The above flags require that the compilation stage assign each function and variable to a separate section, thus solving the above-mentioned problem of "if only a portion of the members in a section are used, then that section is also preserved".
According to the method, through the configuration of the SO file, the depth reduction of the android sol volume can be realized under the condition of little change of the source code, and the execution effect of the android sol volume cannot be influenced. The simplifying effect is generally about 20% -40%, so that the volume of the android application installation package can be effectively simplified, the downloading success rate of the application is further improved, more users are brought to the product, and the popularization efficiency of the product is improved.
