原理本库其实并没有什么黑科技，本库也没有java代码，核心就是2个build.gradle中的task。首先，原理就是基于android sdk中提供的工具----traceview，和dmtracedump。traceview会生成.trace文件，该文件记录了函数调用顺序，函数耗时，函数调用次数等等有用的信息。而dmtracedump 工具就是基于trace文件生成报告的工具，具体用法不细说。dmtracedump 工具大家一般用的多的选项就是生成html报告，或者生成调用顺序图片（看起来很不直观）。首先说说为什么要用traceview，和dmtracedump来作为得到函数调用顺序的，因为这个工具既然能知道cpu执行时间和调用次数以及函数调用树（看出函数调用顺序很费劲）比如android studio是这样呈现.trace文件的解析视图的
import java.io.BufferedReader;import java.io.FileReader;import java.io.IOException;import java.util.ArrayList;import java.util.Arrays;import java.util.Collections;import java.util.regex.Matcher;import java.util.regex.Pattern;public class Sort implements Comparable<Sort> { static String uri = "D:/Application/eclipse/javaworkspace/Test/src/JB/1.text"; String str = ""; String content = ""; public Sort(String str,String content) { super(); this.str = str; this.content = content; } public static void main(String[] args) throws IOException { // TODO Auto-generated method stub ArrayList<Sort> list = new ArrayList<>(); BufferedReader in = new BufferedReader(new FileReader(uri)); String a = ""; while ((a = in.readLine()) != null) { //System.out.println(Long.valueOf(getIndexStr(a))); if(a.contains("com.zjw.appmethodorder")){ list.add(new Sort(getIndexStr(a),a)); } } Collections.sort(list); for (Sort sort : list) { System.out.println(sort.content); } } public static String getIndexStr(String str) { String regEx = "(?<=\\[)(\\S+)(?=\\])";// 匹配[]中的数字 Pattern p = Pattern.compile(regEx); Matcher m = p.matcher(str.trim()); while (m.find()) { return m.group().trim(); } return ""; } @Override public int compareTo(Sort o) { // TODO Auto-generated method stub //return 0; return (int) (Long.valueOf(str) - Long.valueOf(o.str)); }}结果发现过滤后的东西序列号是按顺序的但是并不是代码执行的逻辑顺序。我擦怎么办，工具代码也写了，居然不是我想要的结果，好在花了一些时间发现dmtracedump -ho 选项，经过研究发现，这玩意输出的内容居然是按逻辑顺序从上到下的，于是基于这一点我写一个项目，其实核心就是2个task完成了了解所有函数调用顺序的目的。 //核心任务：在captures文件目录下输出 基于最新.trace文件的函数调用信息的txt版本//说明：dmtracedump 为 android sdk自带工具，要执行dmtracedump命令则需要先添加环境变量task AppOutPutMethodOrder() { doLast { def capturesDirPath = project.getProjectDir().getParentFile().path + File.separator + "captures"; def capturesDir = file(capturesDirPath); def traceType = "trace" if (!capturesDir.exists() || !capturesDir.canRead()) { return } def map = new TreeMap<Long, String>( new Comparator<Long>() { public int compare(Long obj1, Long obj2) { return obj2.compareTo(obj1); } }); //遍历拿到trace 文件名 然后排序 找到最大时间数的trace就是最新的文件，拿到字符串 capturesDir.list(new FilenameFilter() { @Override boolean accept(File dir, String name) { if (name.contains(traceType)) { def substring = name.substring(name.length() - 22, name.length() - 6).trim() String regEx = "[^0-9]" Pattern p = Pattern.compile(regEx) Matcher m = p.matcher(substring) def time = m.replaceAll("").trim() map.put(Long.parseLong(time), name) } return false } }) def lastTraceName = ""; Set<Long> keySet = map.keySet(); Iterator<Long> iterator = keySet.iterator(); while (iterator.hasNext()) { Long key = iterator.next(); lastTraceName = map.get(key); break; } def tracePath = capturesDirPath + File.separator + lastTraceName println "===== tracePath is ${tracePath} ==========" def orderPath = capturesDirPath + File.separator + "base_order.txt" def orderFile = file(orderPath) if(orderFile.exists()){ orderFile.write("") } Runtime runtime = Runtime.getRuntime(); //说明：dmtracedump 为 android sdk自带工具，要执行dmtracedump命令则需要先添加环境变量 def baseComand = "dmtracedump -ho " + tracePath + " >> " + orderPath def command = "" String[] cmdArray = null; String osName = System.getProperty("os.name"); String osNameMatch = osName.toLowerCase(); if(osNameMatch.contains("windows")) { command = "cmd /c start /b "+baseComand; }else { cmdArray = ["bash", "-c", baseComand]; } try { if (cmdArray != null) { runtime.exec(cmdArray); } else { runtime.exec(command); } } catch (Exception e) { println "=====Exception: ${e.getCause()} ==========" } }}//这里AppFilterMethodOrder 任务其实也不需要 执行找到 \captures 目录找到 base_order.txt//用Notepad++ 使用正则 先过滤 带 xit 的行 （我们只关注ent 行就行，ent代表进入执行函数 xit代表退出函数）再过滤掉你不关心的包名// Notepad++ 中过滤将会使用到的命令行如下//^.*xit.*$ //去除掉 含有 xit 字符串的行 然后替换为空// ^((?!XXX).)*$ //去除不包含XXX的行 然后替换为空//^\s+ //合并空行 然后替换为空task AppFilterMethodOrder(){ doLast{ def capturesDirPath = project.getProjectDir().getParentFile().path + File.separator + "captures"; def orderPath = capturesDirPath + File.separator + "base_order.txt" if(!file(orderPath).exists()){ return } BufferedReader inputStream = new BufferedReader(new FileReader(orderPath)); def filterOrderPath = new File(capturesDirPath + File.separator + "order.txt") if (!filterOrderPath.exists()){ filterOrderPath.createNewFile(); }else { filterOrderPath.write("") } String content ; while ((content = inputStream.readLine()) != null) { if(content.contains(" ent ") //com.zjw.appmethodorder 这里可以修改成你想要留下的包名对应的函数调用信息 && content.contains("com.zjw.appmethodorder") ){ filterOrderPath .append(content+"\n") } } }}3.如何使用讲了一堆原理我们来说说这个库怎么用吧。 首先编译运行项目，然后点击下图的时钟（这是使用工具打trace start 和 end）进行操作，可以参考上文所说的动作简介（记住你操作想想你的生命周期函数调用顺序，待会可以和生成的captures目录下base_order.txt或者生成的order.txt中的函数顺序做做对比）然后再点一次下图那个时钟。还有一种记录trace start 和 end的方式就是在修改代码,即使用
然后双击右侧面板的 这一步完成就将在 等待任务执行完成，再执行
4.关于扩展和改造

或者这样的
(上面这张图是网上找的，侵删)用上面这2个图发现你要清晰知道函数调用看懂了才是见鬼了。或者使用dmtracedump 工具解析生成的html长下面这样（dmtracedump 生成图片就不说了 生成出的图片也根本看不出顺序这个就略过了）
一开始我以为 Method 序列号有戏于是乎冲动的我把带序号的东西内容复制出来写了一个脚本对他们进行排序代码如下：
以上操作完成后即会在captures目录生成
该任务目的就是过滤其他非相关包名，留下自己包名的函数，任务执行完成将在
接下来打开
这里稍作修改即可。注意
