AndroidStudio(4.1.1) 导入framework.jar

在编译rom的out目录下，找到framework.jar (可以将classes.jar修改为classes.zip解压后发现很多系统的class文件)

out/target/common/obj/JAVA_LIBRARIES/framework_intermediates/classes.jar 重命名为 framework.jar

如图所示，放到app/libs/framework.jar

gradle.projectsevaluated {
    tasks.withType(JavaCompile) {
        options.compilerArgs << '-Xbootclasspath/p:/home/liujin/AndroidStudioProjects/application1111/app/libs/framework.jar'
    }
}

　　dependencies { compileonly fileTree(include: ['*.jar'], dir: 'libs') }

preBuild {
    doLast {
        def imlFile = file(project.name + ".iml")
        println('Change ' + project.name + '.iml order')
        try {
            def parsedXml = (new XmlParser()).parse(imlFile)
            def jdkNode = parsedXml.component[1].orderEntry.find { it.'@type' == 'jdk' }
            parsedXml.component[1].remove(jdkNode)
            def sdkString = "Android API " + android.compileSdkVersion.substring("android-".length()) + " Platform"
            new groovy.util.Node(parsedXml.component[1], 'orderEntry', ['type': 'jdk', 'jdkName': sdkString, 'jdkType': 'Android SDK'])
            groovy.xml.XmlUtil.serialize(parsedXml, new FileOutputStream(imlFile))
        } catch (FileNotFoundException e) {
            // nop, iml not found
        }
    }
}
gradle.projectsevaluated {
    tasks.withType(JavaCompile) {
        Set fileSet = options.bootstrapClasspath.getFiles()
        List newFileList =  new ArrayList<>();
        //"../framework.jar" 为相对位置，需要参照着修改，或者用绝对位置
        newFileList.add(new File("libs/framework.jar"))
        newFileList.addAll(fileSet)
        options.bootstrapClasspath = files(newFileList.toArray())
    }
}

我们可以看到ActivityManger.getService()是标红的，但是AndroidStudio依旧可以运行．
