前置条件：
1、系统版本Android7.0、已Root
2、Demo代码未修改逻辑，只添加了几行日志
3、运行前已导入so [libnativecpp.so、libnativecpptwo.so]到此目录: /data/user/0/com.example.nativecpp/files/dynamic_so/
4、
arm-linux-androideabi-readelf -d libnativecpptwo.so

Dynamic section at offset 0xdc8 contains 28 entries:
Tag Type Name/Value
0x0000000000000001 (NEEDED) Shared library: [libnativecpp.so]
0x0000000000000001 (NEEDED) Shared library: [liblog.so]
0x0000000000000001 (NEEDED) Shared library: [libm.so]

0x000000000000000e (SONAME) Library soname: [libnativecpptwo.so]

5、$ /data/user/0/com.example.nativecpp/files/dynamic_so # ls -al
-rwxrwxrwx 1 root root 1414352 2023-03-01 11:48 libnativecpp.so
-rwxrwxrwx 1 root root 60120 2023-03-01 11:48 libnativecpptwo.so

运行日志如下：

添加日志代码：
public class DynamicSo {
public static void loadStaticSo(File soFIle, String path) {
try {
ElfParser parser = null;
List dependencies = null;
try {
parser = new ElfParser(soFIle);
dependencies = parser.parseNeededDependencies();
} catch (Throwable e) {

} finally {
if (parser != null) {
parser.close();
}
}
Log.i("hello", "dependencies: " + dependencies);
//如果nativecpp3->nativecpptwo->nativecpp 则先加载 DynamicSo.loadStaticSo(nativecpptwo)，此时nativecpp作为nativecpptwo的直接依赖被加载了
//不能直接加载nativecpp3，导致加载直接依赖nativetwo的时候nativecpp没加载导致错误。 这个可以优化，比如递归
for (final String dependency : dependencies) {

            try {
                File file = new File(path + dependency);
                if (file.exists()) {
                    //递归查找
                    loadStaticSo(file, path);
                } else {
                    // so文件不存在这个文件夹，代表是ndk中的so，如liblog.so，则直接加载
                    // 把本来lib前缀和.so后缀去掉即可
                    String dependencySo = dependency.substring(3, dependency.length() - 3);
                    //在application已经注入了路径DynamicSo.insertPathToNativeSystem(this,file) 所以采用系统的加载就行
                    Log.i("hello", "dependencySo: " + dependencySo);
