Hi,
First of all the NDK is not providing support to load multiple shared
library at run-time!
The only way is load the depended so library manually in memory and then
call or do the required things as you want. for example you want to call a
method of shared library called "main" with the method defined as " int
main(int argc, char** argv)"
Currently this only the best way to solve the loading of multiple shared
library problem in Android.
example....
void *lib_handle;
int (*fnmain)(int, char **);
char *error;
lib_handle = dlopen("/data/data/com.mycompany.myproject/lib/libmain.so",
RTLD_LAZY);
if (!lib_handle)
{
fprintf(stderr, "%s\n", dlerror());
exit(1);
}
fnmain = dlsym(lib_handle, "main");
if ((error = dlerror()) != NULL)
{
fprintf(stderr, "%s\n", error);
exit(1);
}
ret = (*fnmain)(argc, argv);
dlclose(lib_handle);
Ping me back if you have any trouble in that!
