问题来源：用到系统方法WifiMnanger.ActionLinstener时Android Studio编译报错

环境：Android 12(S)

1.将系统编译好的framework-wifi.jar，framework-minus-apex.jar放在/app/libs/文件夹中

在App的build.gradle中加入以下代码

复制代码

dependencies {
	...
    compileOnly files('libs\\framework-minus-apex.jar')
    compileOnly files('libs\\framework-wifi.jar')
    ...
}

2.在项目的build.gradle中加入以下代码

复制代码

// Top-level build file where you can add configuration options common to all sub-projects/modules.
plugins {
    id 'com.android.application' version '7.4.2' apply false
    id 'com.android.library' version '7.4.2' apply false
}
allprojects {
    gradle.projectsEvaluated {
        tasks.withType(JavaCompile) {
            options.compilerArgs.add('-Xbootclasspath/p:app/libs/framework-wifi.jar')
            options.compilerArgs.add('-Xbootclasspath/p:app/libs/framework-minus-apex.jar')
        }
    }

    gradle.projectsEvaluated {
        tasks.withType(JavaCompile) {
            Set<File> fileSet = options.bootstrapClasspath.getFiles()
            List<File> newFileList =  new ArrayList<>();
            newFileList.add(new File("app/libs/framework-wifi.jar"))
            newFileList.add(new File("app/libs/framework-minus-apex.jar"))
            newFileList.addAll(fileSet)
            options.bootstrapClasspath = files(
                    newFileList.toArray()
            )
        }
    }
}

3.还是标红，但是编译正常，运行正常
