我在android环境中使用了Log4J。
但是,它不起作用。
以下链接是我关于Log4J的logcat消息。
(我没有声誉,我无法上传截图。)
这是我的java bild路径图片链接。

的 ConfigureLog4J.java
package com.example.log4j_test;
import java.io.File;
import org.apache.log4j.Level;
import android.os.Environment;
import de.mindpipe.android.logging.log4j.LogConfigurator;
public class ConfigureLog4J {
public static void configure() {
final LogConfigurator logConfigurator = new LogConfigurator();
logConfigurator.setFileName(Environment.getExternalStorageDirectory() + File.separator + "myapp.log");
logConfigurator.setRootLevel(Level.DEBUG);
// Set log level of a specific logger
logConfigurator.setLevel("org.apache", Level.ERROR);
logConfigurator.configure();
}
}
的 MainActivity.java
package com.example.log4j_test;
import org.apache.log4j.Logger;
import android.app.Activity;
import android.os.Bundle;
public class MainActivity extends Activity {
private final Logger logger = Logger.getLogger(MainActivity.class);
static {
ConfigureLog4J.configure();
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
logger.info("This message should be seen in log file and logcat");
}
}
的 log4j.properties
# Log4j Setting file
log4j.rootLogger=INFO, console
# Daily file log
log4j.appender.logfile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.logfile.File=C:/Data/Log/data.log

#log4j.logger.name.of.the.package.two=INFO, logfile
log4j.logger.com.example.log4j_test=INFO, logfile
的的AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

请给我一些建议。
感谢。
