功能

1、这是一个使用AOP切入Activity声明周期的方式来判断当前应用进入前后台，并打印相应日志

打印的日志为：

12-03 18:28:48.385 18001-18001/? E/ActivityAnnotationAspect: after MainActivity->onCreate
12-03 18:28:48.435 18001-18001/? E/ActivityAnnotationAspect: after MainActivity->onResume
12-03 18:28:48.435 18001-18001/? D/ActivityAnnotationAspect: app become foreground
12-03 18:28:52.665 18001-18001/? E/ActivityAnnotationAspect: after MainActivity->onPause
12-03 18:28:52.685 18001-18001/? E/ActivityAnnotationAspect: after TestActivity->onCreate
12-03 18:28:52.695 18001-18001/? E/ActivityAnnotationAspect: after TestActivity->onResume
12-03 18:28:53.185 18001-18001/? E/ActivityAnnotationAspect: after MainActivity->onStop
12-03 18:28:56.125 18001-18001/? E/ActivityAnnotationAspect: after TestActivity->onPause
12-03 18:28:56.465 18001-18001/? E/ActivityAnnotationAspect: after TestActivity->onStop
12-03 18:28:56.625 18001-18001/? D/ActivityAnnotationAspect: app become background
12-03 18:29:03.535 18001-18001/? E/ActivityAnnotationAspect: after TestActivity->onResume
12-03 18:29:03.535 18001-18001/? D/ActivityAnnotationAspect: app become foreground

2、可以注册Activity切前后台的回调

/**
 * @author xueshanshan
 * @date 2018/12/3
 */
public class MyApp extends Application implements OnAppVisibleListener {
    private static final String TAG = MyApp.class.getSimpleName();

    @Override
    public void onCreate() {
        super.onCreate();
        ActivityAnnotationAspect.registerAppVisiableChangedListener(this);
    }

    @Override
    public void becomeForeground() {
        Log.e(TAG, "becomeForeground");
    }

    @Override
    public void becomeBackground() {
        Log.e(TAG, "becomeBackground");
    }
}

3、也提供了LifecycleUtil implements Application.ActivityLifecycleCallbacks来监听activity生命周期的回调

//在Application中使用
LifecycleUtil.init(this);
LifecycleUtil.get().registerAppVisiableChangedListener(this);

4、由于aop导入配置代码较多，所以本项目也写了aop的插件来配置aop的依赖，运用我的插件，会使得aop导入非常方便

项目的build.gradle配置

buildscript {
    repositories {
        //maven { url uri('repo-aop-plugin') }
        jcenter() //该插件已上传至jcenter
    }
    dependencies {
        classpath 'com.star.plugin:aop-plugin:0.0.1'
    }
}

app或其他module配置

apply plugin: 'aop-plugin'

//可配置项
aop{
    enable = true/false  //是否使这个插件可用，默认为true
    enableLog = true/false  //是否打印编译过程的日志，默认为true
}
