首先 , 参考 【AOP 面向切面编程】AOP 简介 ( AspectJ 简介 | AspectJ 下载 ) 三、AspectJ 下载 博客 , 下载 AspectJ ;
下载地址为 https://www.eclipse.org/aspectj/downloads.php , 这里下载 AspectJ 1.8.10, Released 12 Dec 2016 版本 , 下载链接为 https://ftp.jaist.ac.jp/pub/eclipse/tools/aspectj/aspectj-1.8.10.jar ;
下载下来的 aspectj-1.8.10.jar 文件有
KB , 拷贝到 D:\AspectJ 目录中 , 解压该文件 :
进入 D:\AspectJ\aspectj-1.8.10\lib 目录 , aspectjrt.jar 是 AspectJ 的核心 jar 包 ;
将上述 aspectjrt.jar 文件 , 拷贝到 Android Studio 工程的 AOP_Demo\app\libs 目录中 , 其中 AOP_Demo 是 AS 工程根目录 ;
参考 【错误记录】Android Studio 配置 AspectJ 报错 ( Failed to create Jar file C:\xxx\aspectjtools-1.8.10.jar. ) 博客 , 配置 Gradle 和 Gradle 插件版本 ;
Gradle 版本 : 在 \gradle\wrapper\gradle-wrapper.properties 中配置
版本的 Gradle ;
distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.4-bin.zip
Gradle 插件版本 : 在
版本的 Gradle 插件 ;
buildscript {
dependencies {
classpath "com.android.tools.build:gradle:3.6.1"
}
}
配置 AspectJ 依赖 : implementation files('libs/aspectjrt.jar')
配置 AspectJ 编译选项 :
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'org.aspectj:aspectjtools:1.8.10'
classpath 'org.aspectj:aspectjweaver:1.8.10'
}
}

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;
}
}
}
}
