安卓源码调试之-JNI中添加log输出

//1.引入头文件
#include <utils/Log.h>
//2.定义LOG函数
#define LOGD(...)  __android_log_print(ANDROID_LOG_DEBUG,TAG,__VA_ARGS__)
//3.输出LOG信息
static void setLight_native(JNIEnv *env, jobject clazz, int ptr,
       int light, int colorARGB, int flashMode, int onMS, int offMS, int brightnessMode)
{   
   Devices* devices = (Devices*)ptr;
   light_state_t state;
   if (light < 0 || light >= LIGHT_COUNT || devices->lights[light] == NULL) {
       return ;
   }    
//输出方法调用信息
LOGD("setLight_native,ptr=%d,light=%d,colorARGB=%d,flashMode=%d,onMS=%d,offMS=%d,brightnessMode=%d",ptr,light,colorARGB,flashMode, onMS, offMS, brightnessMode);
   memset(&state, 0, sizeof(light_state_t));
