How to implement debug logs in Android's JNI

Question

I am trying to implement debug logs in the following file in the android code.

frameworks/base/services/jni/com_android_server_BatteryService.cpp

I have tried LOGE and __android_log_write(), however things doesn't work. I have also tried to create a text file in the filesystem and then write it, however this also didnt work.

Answer 1

#define LOG_TAG "BatteryService"
#include "utils/Log.h"

/* some code*/

LOGE("Mine logging is better than yours.");
