NativeUtil重复了.

[GordonHuangYong]

我们编译了一个aar, 然后使用本方案进行了加固. 发布给甲方使用. 刚好甲方的app也使用了这个方案对apk进行加固.
于是就导致了这个错误

这种情况如何解决?

[maoabc]

改名 ，相关方法在nmm-protect/apkprotect/src/main/java/com/nmmedit/apkprotect/dex2c/DexConfig.java中。编译后so命名在BuildNativeLib.java中，缩减成一个so需要改CMake以及一些打包逻辑，这些在源码中都有注释。

[GordonHuangYong]

我做了修改, 还是不成功.

报错下如下

修改的内容如下:

1. CMakeUtils.java

    public static void writeCmakeFile(File cmakeTemp, String libName) throws IOException {
        final BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(
                new FileInputStream(cmakeTemp), StandardCharsets.UTF_8));

        String lines = bufferedReader.lines().collect(Collectors.joining("\n"));
        //定位cmake里的语句,防止替换错误
        String libNameFormat = "set\\(LIBNAME_PLACEHOLDER \"%s\"\\)";

        //替换原本libname
        lines = lines.replaceAll(String.format(libNameFormat, "wtjp"), String.format(libNameFormat, libName));

        try (FileWriter fileWriter = new FileWriter(cmakeTemp)) {
            fileWriter.write(lines);
        }
    }

2. CMakeLists.txt

cmake_minimum_required(VERSION 3.6)
project(wtjp)


add_subdirectory(vm)


include_directories(.)
include_directories(generated/)


file(GLOB GEN_SOURCES generated/*_functions.c generated/jni_init.c)

set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -fvisibility=hidden ")

#外部程序处理时替换 LIBNAME_PLACEHOLDER
set(LIBNAME_PLACEHOLDER "wtjp")


add_library(${LIBNAME_PLACEHOLDER} SHARED ConstantPool.c ${GEN_SOURCES} )

target_link_libraries(${LIBNAME_PLACEHOLDER} ${LIBNMMVM_NAME} log)

4. vm/CMakeLists.txt

cmake_minimum_required(VERSION 3.6)

include_directories(..)
include_directories(./include)

        DexCatch.cpp
        Exception.cpp

        )

set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -fvisibility=hidden -DNDEBUG")

add_library(${LIBNMMVM_NAME} SHARED ${VM_SRC_FILES})

target_link_libraries(${LIBNMMVM_NAME} log)

target_include_directories(${LIBNMMVM_NAME} PUBLIC include)

6. BuildNativeLib.java

public class BuildNativeLib {
    //库名称
    public static final String NMMP_NAME = "wtjp";

    //
    //虚拟机库名称,如果cmake里配置为静态库,这个可以忽略
    public static final String VM_NAME = "wtjvm";

}

你找一下打包获得so文件相关逻辑，以及查看ndk编译后是否正确生成文件。打包这部分逻辑简单，没有细致处理java代码跟cmake文件之间匹配问题，实际看报错改。

[maoabc]

我仔细看了你日志，你没使用修改后的代码。需要更新vmsrc.zip,在mksrc目录下有独立的cmake文件跟vmsrc.zip生成脚本，这里修改后运行脚本就能更新vmsrc.zip。

yes! 修改好了.目前正常.
