AsmCost

Aop之asm切面编程，计算方法耗时插件。

Gradle

（1）根项目下依赖

repositories {
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.0.0'
    classpath 'com.xyzlf.asm:method-cost:0.0.2'//依赖方法耗时插件
}

（2）依赖插件及基本库

apply plugin: 'com.android.application'
apply plugin: 'method-cost' //依赖方法耗时插件

android {
    //...
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support:appcompat-v7:26.1.0'

    compile 'com.xyzlf.asm:common-lib:0.0.2'//依赖方法耗时注解
}

使用方式

在方法上方，使用注解@Cost即可。

（1）计算show方法耗时：

@Cost
private void show() {
    int count = 0;
    for (int i = 0; i < 100000; i++) {
        count++;
    }
}

（2）当执行show方法时，会打印耗时日志，过滤关键字 cost：

11-16 00:34:53.066 9619-9619/com.xyzlf.demo I/System.out: [cost] ======== onCreate start ========
11-16 00:34:53.091 9619-9619/com.xyzlf.demo I/System.out: [cost] onCreate cost 24418 microsecond
11-16 00:34:53.091 9619-9619/com.xyzlf.demo I/System.out: [cost] ======== onCreate end ========

11-16 00:34:53.066 9619-9619/com.xyzlf.demo I/System.out: [cost] ======== show start ========
11-16 00:34:53.091 9619-9619/com.xyzlf.demo I/System.out: [cost] onCreate cost 2145 microsecond
11-16 00:34:53.091 9619-9619/com.xyzlf.demo I/System.out: [cost] ======== show end ========
