Re: [Log4cplus-devel] [log4cplus:bugs] #290 How to use log4cplus in android device

[Vladimir \Equidamoid\ S. <equ...@gm...>]

Hi laiyierjiangsu,

I'm using log4cplus in crossplatform android/ios app.
The first option is to write your own appender. The simpliest one 
contains just one overridded method:
 > void LogcatAppender::append(const 
log4cplus::spi::InternalLoggingEvent &event){
 > log4cplus::tstring txt = formatEvent(event);
 > __android_log_write(ANDROID_LOG_WARN, "yourappname", txt.c_str());
 > }
__android_log_write is defined in android/log.h header.

Another way is to use SocketAppender class to send logs over wifi 
connection (I use my laptop as a receiver) and use loggingserver app to 
receive and read them.

Also there is a possibility to redirect app's stdout to logcat ( 
http://stackoverflow.com/questions/10531050/redirect-stdout-to-logcat-in-android-ndk 
) but I haven't tried it.
