问题描述

I am trying to print log messages within core Android framework files. For example, I tried logging messages within MediaRecorderClient.cpp under frameworksasemedialibmediaplayerservice. I've tried LOGV, LOGE, LOGD, printf, and __android_log_print, without any success.

Which command should I use to print log messages?

解决方案

Log should be used, but it will print to logcat not system print.

Example:

Log.d("filter", example text); // filter is any tag you want to use as filter

You can open logcat in eclipse from window-show view -> other -> android -> logcat
