Using log4j in Android

In Android, the implementation of the output log content in the SD card file, the practice is:

1. Importer of two jar packages

650) this.width=650; "src=" Http://s1.51cto.com/wyfs02/M01/79/FC/wKioL1agQQGjIHylAAAOrxTQSxs168.png "title=" 1.png " alt= "Wkiol1agqqgjihylaaaorxtqsxs168.png"/>

2. Test code

import de.mindpipe.android.logging.log4j.logconfigurator;import java.io.file;import  Android.os.environment;import org.apache.log4j.level;import org.apache.log4j.logger; public  class baseactivity extends activity {    private logger  glogger;         public void configlog ()      {        final LogConfigurator  Logconfigurator = new logconfigurator ();                  logconfigurator.setfilename ( Environment.getexternalstoragedirectory ()  + File.separator +  "Crifanli_log4j.log");         // Set the root log level         logconfigurator.setrootlevel (level.debug);         // set log level of a specific  Logger        logconfigurator.setlevel ("Org.apache",  Level.ERROR) ;         logconfigurator.configure ();          //glogger = logger.getlogger (This.getclass ());         glogger = logger.getlogger ("Crifanlilog4jtest");    }           @Override     protected void  OnCreate (bundle savedinstancestate)  {        configlog ();         glogger.debug ("Test android log to file  in sd card using log4j ");         }

<uses-permission android:name= "Android.permission.WRITE_EXTERNAL_STORAGE"/>&NBSP;

Otherwise it will be reported caused by:java.io.FileNotFoundException:/storage/sdcard0/crifanli_log4j.log:open failed:eacces ( Permission denied) error

Finally, you can implement

(1) The corresponding Crifanli_log4j.log file can be generated in the/mnt/sdcard

(2) The contents of the log output are debug and correspond to their own string identifiers Crifanlilog4jtest
