Android日志工具类

为了方便日志管理，创建一个日志工具类。

开发过程中使用日志DEBUG = true发布程序时关闭日志DEBUG = false

public class LogUtil
{
	
	
	// true:打印日志，false:关闭日志
	private static final boolean DEBUG = true;
	// 日志标签
	private static final String TAG = "PhoneSafer";

	// Send a VERBOSE log message
	public static void v(String msg)
	{
		if (DEBUG)
			Log.v(TAG, msg);
	}

	public static void v(Object msg)
	{
		v(msg.toString());
	}

	public static void v(String tag, String msg)
	{
		v(msg);
	}

	// Send a WARN log message
	public static void w(String msg)
	{
		if (DEBUG)
			Log.w(TAG, msg);
	}

	public static void w(Object msg)
	{
		w(msg.toString());
	}

	// Send an ERROR log message
	public static void e(String msg)
	{
		if (DEBUG)
			Log.e(TAG, msg);
	}

	public static void e(Object msg)
	{

	}

	public static void i(String msg)
	{

			Log.i(TAG, msg);
	}

	public static void i(Object msg)
	{

	}

	// Send a DEBUG log message.
	public static void d(String msg)
	{

			Log.d(TAG, msg);
	}

	public static void d(Object msg)
	{
