本文介绍了一种在Android平台上的WebKit模块中遇到的日志显示问题及其解决方案。由于配置文件中的宏定义冲突导致日志无法正常输出，通过调整头文件的包含顺序及取消宏定义解决了这一问题。

#undef LOG

#include "utils/Log.h"

recently i tried to see logs in native WebKit
but in the end found nothing in ddms

finally i found the cause is that
in WebCore/config.h , it includes <wtf/Assertions.h>
which defines LOG macro

therefore the LOG{VDIEW} macro will be redirected to WTFLog
instead of android_log

try to do #undef LOG before you including "utils/Log.h" or "cutils/
log.h"

and try not to include them before including "config.h"
