（1）android studio工程根目录的build.gradle添加：

buildscript {
        dependencies {
            classpath 'org.aspectj:aspectjtools:1.9.19'
            classpath 'org.aspectj:aspectjweaver:1.9.19'
        }
    }

（2）app模块build.gradle：

implementation 'org.aspectj:aspectjrt:1.9.19'

同时在这个build.gradle的最末尾地方增加：

import org.aspectj.bridge.IMessage
    import org.aspectj.bridge.MessageHandler
    import org.aspectj.tools.ajc.Main
    
    final def log = project.logger
    final def variants = project.android.applicationVariants
    
    //在构建工程时，执行编辑
    variants.all { variant ->
        if (!variant.buildType.isDebuggable()) {
            log.debug("Skipping non-debuggable build type '${variant.buildType.name}'.")
            return;
        }
    
        JavaCompile javaCompile = variant.javaCompile
        javaCompile.doLast {
            String[] args = ["-showWeaveInfo",
                             "-1.9",
                             "-inpath", javaCompile.destinationDir.toString(),
                             "-aspectpath", javaCompile.classpath.asPath,
                             "-d", javaCompile.destinationDir.toString(),
                             "-classpath", javaCompile.classpath.asPath,
                             "-bootclasspath", project.android.bootClasspath.join(File.pathSeparator)]
            log.debug "ajc args: " + Arrays.toString(args)
    
            MessageHandler handler = new MessageHandler(true);
            new Main().run(args, handler);
            for (IMessage message : handler.getMessages(null, true)) {
                switch (message.getKind()) {
                    case IMessage.ABORT:
                    case IMessage.ERROR:
                    case IMessage.FAIL:
                        log.error message.message, message.thrown
                        break;
                    case IMessage.WARNING:
                        log.warn message.message, message.thrown
                        break;
                    case IMessage.INFO:
                        log.info message.message, message.thrown
                        break;
                    case IMessage.DEBUG:
                        log.debug message.message, message.thrown
                        break;
                }
            }
        }
    }

如果没有上面部分配置，没有日志输出。

（3）上层Java编码：

定义一个接口，这个接口后面将以注解方式注入到被监测的函数名上：

package com.example.myapplication;
    
    import java.lang.annotation.ElementType;
    import java.lang.annotation.Retention;
    import java.lang.annotation.RetentionPolicy;
    import java.lang.annotation.Target;
    
    @Target(ElementType.METHOD)
    @Retention(RetentionPolicy.RUNTIME)
    public @interface MyTimer {
        String value();
    }

package com.example.myapplication;
    
    import android.util.Log;
    
    import org.aspectj.lang.ProceedingJoinPoint;
    import org.aspectj.lang.annotation.Around;
    import org.aspectj.lang.annotation.Aspect;
    import org.aspectj.lang.annotation.Pointcut;
    import org.aspectj.lang.reflect.MethodSignature;
    
    //一个切面
    @Aspect
    public class AspectMyTimer {
        @Pointcut("execution(@com.example.myapplication.MyTimer *  *(..))")
        public void methodAnnottatedWithMyTimer() {
    
        }
    
        //处理切面
        //@Before 切入点之前运行
        //@After 切入点之后运行
        //@Around 切入点前后都运行
        @Around("methodAnnottatedWithMyTimer()")
        public Object myTimer(ProceedingJoinPoint joinPoint) {
            MethodSignature methodSignature = (MethodSignature) joinPoint.getSignature();
    
            //获得类名
            String className = methodSignature.getDeclaringType().getSimpleName();
    
            //获得当前拦截的方法名
            String methodName = methodSignature.getName();
    
            //获得当前拦截的方法名上标记的注解中的vaule的值
            String value = methodSignature.getMethod().getAnnotation(MyTimer.class).value();
    
            long begin = System.currentTimeMillis();
            try {
                joinPoint.proceed();
            } catch (Throwable e) {
                e.printStackTrace();
            }
            long duration = System.currentTimeMillis() - begin;
    
            String ret = String.format("%s - %s类->%s函数 耗时:%d ms", value, className, methodName, duration);
    
            Log.d("zhangphil", ret);
    
            return ret;
        }
    }

开始注解注入监测性能，被测试的test函数，故意sleep三秒：

import androidx.appcompat.app.AppCompatActivity;
    
    import android.os.Bundle;
    
    import java.util.concurrent.TimeUnit;
    
    public class MainActivity extends AppCompatActivity {
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
    
            try {
                test();
            } catch (InterruptedException e) {
                throw new RuntimeException(e);
            }
        }
    
        @MyTimer("耗时监测")
        private void test() throws InterruptedException {
            TimeUnit.SECONDS.sleep(3);
        }
    }

输出：
