实现一个可定位、可点击的Logcat日志打印工具类

实现一个可定位、可点击的Logcat日志打印工具类

前言：最近发现项目中的使用的Log太多，经常不知道Log日志是在哪个地方备注的。想从日志中看又太麻烦。于是整理此类，方便项目中使用。

效果如下：

在Android Studio的Logcat栏中可直观看到日志在哪个类的哪个方法中。点击后跳转到Log日志位置。
备注：Android Studio定位问题导致定位位置总是比Log日志位置多三行……（目前不知道是哪里出现了什么问题）

代码如下：

package com.lcz.wanandroid_kotlin.utils;

import android.util.Log;

        if (methodCount + stackOffset > trace.length) {
