2、下载android-logging-log4j

http://code.google.com/p/android-logging-log4j/downloads/detail?name=android-logging-log4j-1.0.3.jar&can=2&q=

将以上两个jar包导入工程，编写保存log代码如下：

importorg.apache.log4j.Level;importorg.apache.log4j.Logger;importde.mindpipe.android.logging.log4j.LogConfigurator;importandroid.os.Environment;......此处省略privatevoidsaveLog(){LogConfiguratorlogConfigurator=newLogConfigurator();logConfigurator.setFileName(Environment.getExternalStorageDirectory()+File.separator+"MyApp"+File.separator+"logs"+File.separator+"log4j.txt");logConfigurator.setRootLevel(Level.DEBUG);logConfigurator.setLevel("org.apache",Level.ERROR);logConfigurator.setFilePattern("%d%-5p[%c{2}]-[%L]%m%n");logConfigurator.setMaxFileSize(1024*1024*5);logConfigurator.setImmediateFlush(true);logConfigurator.configure();Loggerlog=Logger.getLogger(MainActivity.class);log.info("info");log.debug("debug");}

运行程序，我们会发现生成/sdcard/MyApp/logs/log4j.txt文件，该文件内容为：

root@android:/sdcard/MyApp/logs#catlog4j.txtcatlog4j.txt2013-12-2402:20:47,236INFO[logger.MainActivity]-[68]info2013-12-2402:20:47,251DEBUG[logger.MainActivity]-[69]debug
