如何使用JNI android获取应用构建配置(Debug或release)？

public class AppConfig {
    static {
        System.loadLibrary("appconfig"); // 加载本地库
    }

    public static native String getBuildConfig(); // 声明JNI接口方法
}

javah -jni com.example.app.AppConfig

#include <jni.h>
#include <string.h>
#include <android/log.h>

JNIEXPORT jstring JNICALL Java_com_example_app_AppConfig_getBuildConfig(JNIEnv *env, jobject obj) {
    #ifdef NDEBUG
        return (*env)->NewStringUTF(env, "Release");
    #else
        return (*env)->NewStringUTF(env, "Debug");
    #endif
}

android {
    // ...

    defaultConfig {
        // ...
        ndk {
            abiFilters 'armeabi-v7a', 'arm64-v8a', 'x86', 'x86_64'
        }
    }

    // ...
}

android {
    // ...

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

    // ...
}

cmake_minimum_required(VERSION 3.4.1)

add_library(appconfig SHARED appconfig.c)

target_link_libraries(appconfig log)

String buildConfig = AppConfig.getBuildConfig();
Log.d("AppConfig", "Build Config: " + buildConfig);
