You can use java logger also here with some customisations..

ConsoleLogHandler.java

<pre><code>package com.sony.evc.vis.system.util.logger;

import java.util.logging.Handler;
import java.util.logging.Level;
import java.util.logging.LogRecord;

import android.util.Log;

public class ConsoleLogHandler extends Handler
{

 @Override
 public void close()
 {}

 @Override
 public void flush()
 {}

 // filter logs and publish them
 @Override
 public void publish(LogRecord record)
 {
 String className = record.getLoggerName() + ": "
 + simplifyClassName(record.getSourceClassName());
 int threadID = record.getThreadID();
 String methodName = record.getSourceMethodName();
 String msg = record.getMessage();
 int level = record.getLevel().intValue();

 logMessage(className, threadID, methodName, msg, level, record.getThrown());
 }

 // simplify class name from full applied package name to simple class
 private String simplifyClassName(String sourceClassName)
 {
 String fullClassName[] = sourceClassName.split("\\.");
 return fullClassName[fullClassName.length - 1];
 }

 private void logMessage(String className, int threadID, String methodName, String msg,
 int level, Throwable throwable)
 {
 if (level == Level.FINE.intValue()) {
 Log.d(className, "ThreadID:" + threadID + "," + methodName + "()," + msg);
 }
 else if (level == Level.INFO.intValue()) {
 Log.i(className, "ThreadID:" + threadID + "," + methodName + "()," + msg);
 }
 else if (level == Level.WARNING.intValue()) {
 Log.w(className, "ThreadID:" + threadID + "," + methodName + "()," + msg, throwable);
 }
 else if (level == Level.SEVERE.intValue()) {
 Log.e(className, "ThreadID:" + threadID + "," + methodName + "()," + msg, throwable);
 }

create enum LogLevel.java

<pre><code>package com.sony.evc.vis.system.util.logger;

import java.util.logging.Level;

public enum LogLevel {
 DEBUG, INFO, WARNING, ERROR, NO_LOG, DISABLE;

 case NO_LOG:
 return Level.OFF;
 case DISABLE:
 return Level.OFF;
 default:

 }
 }
}
</code></pre>

<hr>

You will also need to update Strings.xml as

<pre><code>&lt;!--
 :-Accepted values for global_debuglevel are: "debug", "info", "warning", "error"(in increasing order of priority),No_Log
 and Disable. 
 :-Setting any other value will set "info" level
 --&gt;
 &lt;string name="global_debuglevel"&gt;debug&lt;/string&gt;

 &lt;!--
 :-Accepted values for app_debuglevel are: "debug", "info", "warning", "error"(in increasing order of priority)
 and No_Log
 :-Setting any other value will set "info" level
 --&gt;
 &lt;string name="app_debuglevel"&gt;debug&lt;/string&gt;
</code></pre>

<hr>

From the start of application just init the Logger as

<pre><code> String service_version = getString(R.string.service_version);
 String global_debugLevel = getString(R.string.global_debuglevel);
 String service_debugLevel = getString(R.string.service_debuglevel);
 LoggerFactory.init(service_version, global_debugLevel,
 service_debugLevel);
</code></pre>

<hr>

For printing Logs write:

<pre><code>Log.info(" message ");
Log.fine(" message ");
Log.severe(" message ");
Log.warning(" message ");
</code></pre>

I ended up using <a href="http://tony19.github.com/logback-android/" rel="nofollow">logback-android</a>. I will leave this question open a bit longer in case someone comes up with a better solution.

According to <a href="http://developer.android.com/reference/android/util/Log.html#isLoggable%28java.lang.String,%20int%29" rel="noreferrer">the documentation</a> there are only two ways to change the default logging level from INFO to lower levels (such as DEBUG):

<ol>
<li><code>setprop log.tag.&lt;YOUR_LOG_TAG&gt; &lt;LEVEL&gt;</code>, or</li>
<li><code>log.tag.&lt;YOUR_LOG_TAG&gt;=&lt;LEVEL&gt;</code> in /data/local.prop.</li>
</ol>

Is it possible to bundle the logging configuration within the application? I'm looking for the equivalent of <code>logging.properties</code> or <code>logback.xml</code>, configuration files that are bundled with the application and alter the logging behavior at load-time. The goal is to avoid manually configuring each device that the application will run on.
