环境配置【二种方案】

方案一、Module配置—Aspectj

项目的build.gradle配置

buildscript {
    
    repositories {
        google()
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
        

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'org.aspectj:aspectjtools:1.9.1'
        classpath 'org.aspectj:aspectjweaver:1.9.1'
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        mavenCentral()
    }
}

新建一个Module，并配置build.gradle如下

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

    // AOP配置
    compile 'org.aspectj:aspectjrt:1.9.1'
}

// AOP配置
import org.aspectj.bridge.IMessage
import org.aspectj.bridge.MessageHandler
import org.aspectj.tools.ajc.Main

project.android.libraryVariants.all { variant ->
    JavaCompile javaCompile = variant.javaCompile
    javaCompile.doLast {
        String[] args = ["-showWeaveInfo",
                         "-1.8",
                         "-inpath", javaCompile.destinationDir.toString(),
                         "-aspectpath", javaCompile.classpath.asPath,
                         "-d", javaCompile.destinationDir.toString(),
                         "-classpath", javaCompile.classpath.asPath,
                         "-bootclasspath", project.android.bootClasspath.join(File.pathSeparator)]

        MessageHandler handler = new MessageHandler(true)
        new Main().run(args, handler)

        def log = project.logger
        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
                case IMessage.INFO:
                    log.info message.message, message.thrown
                    break
                case IMessage.DEBUG:
                    log.debug message.message, message.thrown
                    break
            }
        }
    }
}

方案二、App Module配置—Aspectj

项目的build.gradle配置

buildscript {
    
    repositories {
        google()
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
        

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'org.aspectj:aspectjtools:1.9.1'
        classpath 'org.aspectj:aspectjweaver:1.9.1'
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        mavenCentral()
    }
}

App Module的build.gradle配置如下

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support.constraint:constraint-layout:1.1.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

    implementation "com.android.support:appcompat-v7:$rootProject.ext.appcompat_v7"
    implementation project(':umeng')

    // AOP配置
    compile 'org.aspectj:aspectjrt:1.9.1' 
}

// AOP配置
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

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",
                         "-1.8",
                         "-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
            }
        }
    }
}

注意：

在library中配置使用project.android.libraryVariants
在application中配置使用project.android.applicationVariants
在library中配置AOP的Module引入到application的module中一样不能使用

通用配置方案

项目的build.gradle配置

buildscript {
    
    repositories {
        google()
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
        

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'org.aspectj:aspectjtools:1.9.1'
        classpath 'org.aspectj:aspectjweaver:1.9.1'
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        mavenCentral()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

// <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
import org.aspectj.bridge.IMessage
import org.aspectj.bridge.MessageHandler
import org.aspectj.tools.ajc.Main

def aop(variants) {
    variants.all { variant ->
        JavaCompile javaCompile = variant.javaCompile
        javaCompile.doLast {
            String[] args = ["-showWeaveInfo",
                             "-1.8",
                             "-inpath", javaCompile.destinationDir.toString(),
                             "-aspectpath", javaCompile.classpath.asPath,
                             "-d", javaCompile.destinationDir.toString(),
                             "-classpath", javaCompile.classpath.asPath,
                             "-bootclasspath", project.android.bootClasspath.join(File.pathSeparator)]

            MessageHandler handler = new MessageHandler(true)
            new Main().run(args, handler)

            def log = project.logger
            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
                    case IMessage.INFO:
                        log.info message.message, message.thrown
                        break
                    case IMessage.DEBUG:
                        log.debug message.message, message.thrown
                        break
                }
            }
        }
    }
}

在library中使用配置如下

// AOP 面向切面
rootProject.aop(project.android.libraryVariants)

dependencies {
    implementation 'org.aspectj:aspectjrt:1.9.1'    // AOP 面向切面
}

在application中使用配置如下

// AOP 面向切面
rootProject.aop(project.android.applicationVariants)

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support.constraint:constraint-layout:1.1.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

    implementation 'org.aspectj:aspectjrt:1.9.1'    // AOP 面向切面
}

到此AOP在android studio中的几种配置方案就结束了。
