如何使用C++原生代码链接到Android Studio项目中的GLES2

android {
    // ...
    defaultConfig {
        // ...
        externalNativeBuild {
            cmake {
                cppFlags ""
            }
        }
    }
    // ...
    externalNativeBuild {
        cmake {
            path "CMakeLists.txt"
        }
    }
}

cmake_minimum_required(VERSION 3.4.1)

add_library(native-lib SHARED native-lib.cpp)

# 导入GLES2库
find_library(gles-lib GLESv2)

target_link_libraries(native-lib ${gles-lib})

android {
    // ...
    externalNativeBuild {
        cmake {
            path "CMakeLists.txt"
        }
    }
}

public class MainActivity extends AppCompatActivity {
    // 加载C++库
    static {
        System.loadLibrary("native-lib");
    }

    // 声明C++函数
    public native void nativeFunction();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // 调用C++函数
        nativeFunction();
    }
}
