Мне нужно добавить проект c, который можно скомпилировать с помощью gcc
следующим образом
gcc -I/usr/include/epic5.1 -I/usr/include/i386-linux-gnu/epic5.1 -I./smproject/ -o code code.c ./smproject/smlib.so -lepic5.1
Я переместил содержимое файла code.c
в свой файл Android NDK.cpp(src/main/cpp/native-lib.cpp), а также переместил все файлы в каталог smproject
в каталог src/main/cpp/smproject/
Вот мой контент CMakeList.txt

Я пытался следить за Android NDK, CMake с другими библиотеками, но для меня это не сработало, он начал метать gradle error
попробовал следующее в build.gradle
