可以显示行号的Android Log 工具
Android 的Log 类只能以TAG的方式却分不同类的信息，这里利用反射的方式，将Log所在的行号和类名抓出来，以后转交测试的时候如果看到log的消息就可以快速定位软件的bug

package com.tcl.navigator.utils;import android.util.Log;public class LogUtils {	private static final boolean DEBUG = true;	private static final String TAG = "LogUtils.java";	public static void e(String message) {		if (DEBUG) {			StackTraceElement[] elements = Thread.currentThread().getStackTrace();			if (elements.length < 4) {				Log.e(TAG, "Stack to shallow");			}else{				String fullClassName = elements[3].getClassName();				String className = fullClassName.substring(fullClassName.lastIndexOf(".") + 1);				String methodName = elements[3].getMethodName();				int lineNumber = elements[3].getLineNumber();				Log.e(className + "." + methodName + "():" + lineNumber,message);			}		}	}	public static void d(String message) {		if (DEBUG) {			StackTraceElement[] elements = Thread.currentThread().getStackTrace();			if (elements.length < 3) {				Log.e(TAG, "Stack to shallow");			}else{				String fullClassName = elements[3].getClassName();				String className = fullClassName.substring(fullClassName.lastIndexOf(".") + 1);				String methodName = elements[3].getMethodName();				int lineNumber = elements[3].getLineNumber();				Log.d(className + "." + methodName + "():" + lineNumber,message);			}		}	}	public static void i(String message) {		if (DEBUG) {			StackTraceElement[] elements = Thread.currentThread().getStackTrace();			if (elements.length < 3) {				Log.e(TAG, "Stack to shallow");			}else{				String fullClassName = elements[3].getClassName();				String className = fullClassName.substring(fullClassName.lastIndexOf(".") + 1);				String methodName = elements[3].getMethodName();				int lineNumber = elements[3].getLineNumber();				Log.i(className + "." + methodName + "():" + lineNumber,message);			}		}	}		public static void w(String message) {		if (DEBUG) {			StackTraceElement[] elements = Thread.currentThread().getStackTrace();			if (elements.length < 3) {				Log.e(TAG, "Stack to shallow");			}else{				String fullClassName = elements[3].getClassName();				String className = fullClassName.substring(fullClassName.lastIndexOf(".") + 1);				String methodName = elements[3].getMethodName();				int lineNumber = elements[3].getLineNumber();				Log.w(className + "." + methodName + "():" + lineNumber,message);			}		}	}	public static void v(String message) {		if (DEBUG) {			StackTraceElement[] elements = Thread.currentThread().getStackTrace();			if (elements.length < 3) {				Log.e(TAG, "Stack to shallow");			}else{				String fullClassName = elements[3].getClassName();				String className = fullClassName.substring(fullClassName.lastIndexOf(".") + 1);				String methodName = elements[3].getMethodName();				int lineNumber = elements[3].getLineNumber();				Log.v(className + "." + methodName + "():" + lineNumber,message);			}		}	}	}
