TimeCostPlugin

该插件实现功能：在所有的方法的第一行及最后一行插入一行代码

public void setTheme(int i) {
    TimeCost.setStartTime("com/example/dany/myapplication/CostTimeActivity_setTheme");
    super.setTheme(i);
    Log.i("test", "setTheme");
    TimeCost.setEndTime("com/example/dany/myapplication/CostTimeActivity_setTheme");
}

protected void onPause() {
    TimeCost.setStartTime("com/example/dany/myapplication/CostTimeActivity_onPause");
    super.onPause();
    KotlinInstace.Companion.getInstance().setA(false);
    TimeCost.setEndTime("com/example/dany/myapplication/CostTimeActivity_onPause");
}

private void OutMethod() {
    TimeCost.setStartTime("com/example/dany/myapplication/CostTimeActivity_OutMethod");
    InnerMethod1();
    InnerMethod2();
    InnerMethod3();
    TimeCost.setEndTime("com/example/dany/myapplication/CostTimeActivity_OutMethod");
}

如何使用： project中:

buildscript {

repositories {

 maven {
 
  url "https://plugins.gradle.org/m2/"
  
}

} dependencies {

classpath "gradle.plugin.com.dany.timeplugin:timeplugin:1.0.1"

}

}

app中：

apply plugin: "com.dany.timecost"

timecost {//默认是true，可以不配置这个。false时，只在app中插桩，不处理第三方库

jarEnable false

}

新增如下类在自己的app目录中，包名，类名com.dany.util.TimeCost，方法名setStartTime，setEndTime不能变:

package com.dany.util; //包路径名及类名不能变，否则插入代码失败

import java.util.HashMap; import java.util.Map;

public class TimeCost {

public static Map<String, Long> sStartTime = new HashMap<>();
private static boolean isEnable = true;

public static void setStartTime(String name) {
    if(isEnable) {
        String methodName = name.substring(name.lastIndexOf("_")+1);
        String className = name.substring(name.lastIndexOf("/")+1,name.lastIndexOf("_"));
        System.out.println("costtime start:  class: " +className +"  :  ["+methodName+"]");
    }
    sStartTime.put(name, System.currentTimeMillis());
}

public static void setEndTime(String name) {
    long start = sStartTime.get(name);
    long end = System.currentTimeMillis();
    try {
        if (isEnable && Long.valueOf(end - start) > 1.0){
            String methodName = name.substring(name.lastIndexOf("_")+1);
            String className = name.substring(name.lastIndexOf("/")+1,name.lastIndexOf("_"));
            System.out.println("costtime end:  class: " +className +"  :  ["+methodName+"] "+ " cost " + Long.valueOf(end - start) + " ms"+", thread="+Thread.currentThread().getId());
        }
    }catch (Exception e){
        System.out.println("costtime end:  name: " +name+ " cost " + Long.valueOf(end - start) + " ms");
    }

}

public static void setEnable(boolean enable) {
    isEnable = enable;
}

}

如上类打印log如下： I/System.out: costtime end: class: TestApplication : [onCreate] cost 3 ms, thread=1

I/System.out: costtime end: class: CostTimeActivity : [setTheme] cost 3 ms, thread=1

I/System.out: costtime end: class: CostTimeActivity : [InnerMethod1] cost 100 ms, thread=1

I/System.out: costtime end: class: CostTimeActivity : [InnerMethod2] cost 201 ms, thread=1

I/System.out: costtime end: class: CostTimeActivity : [InnerMethod3] cost 300 ms, thread=1

I/System.out: costtime end: class: CostTimeActivity : [OutMethod] cost 601 ms, thread=1

I/System.out: costtime end: class: CostTimeActivity : [onCreate] cost 671 ms, thread=1

功能及用途：

1.可用于查看某个时间段执行的所有类名 方法名

2.可用于测试app启动过程中冷启动 热启动的时长，及每个方法的执行时间

3.可在任意方法执行时，插入某些功能代码

版本说明： classpath 'com.dany.timeplugin:timeplugin:1.0.1' 只打印app里的方法耗时 classpath 'com.dany.timeplugin:timeplugin:1.0.2' 打印app和jar包里的耗时 classpath 'com.dany.timeplugin:timeplugin:1.0.3' 增加jarEnable false开关，默认是true
