A13的自定义系统服务终于编译成功，他的编译机制和A10 A12（未验证）不同的。集成方式都一样，但是配置编译规则真是一路坎坷。接下来我们总结下A13自定义系统服务的开始流程
一 创建AIDL文件
为了看起来符合代码结构合理，我们要顺着framework/base 架构来添加
在framework/base/core/java/android/flyscale(新建目录）下，创建FlyscaleManager.java，IFlyscaleManager.aidl。
内容如下：

二我们要注册该服务：
理论自己找资料理解，我这边只是做操作说明：

三编译：
如果你添加完了，长舒一口气。那么抱歉，你开心的太早了。这样编译是有问题的。异常日志如下：
看到以上异常，我相信你想的和我一样。在bp文件中显式增加这两个新增文件路径，参与编译就可以了。恭喜你，答错了，错误如下：

exit status 1aidl生成的类在两个地方出现，也是失败的
以上两个现象分析，说明系统默认是编译了新增的aidl文件，但是自己的类找不到，如果显示增加编译那就重复。接下来怎么办呢？
四编译问题的解决：
参考其他系统服务的编译规则：
1）在aidl同目录下增加Android.bp文件
package {
// See: http://go/android-license-faq
// A large-scale-change added 'default_applicable_licenses' to import
// all of the 'license_kinds' from "frameworks_base_license"
// to get the below license kinds:
// SPDX-license-identifier-Apache-2.0
default_applicable_licenses: ["frameworks_base_license"],
}
filegroup {
name: "framework-flyscale-sources",
srcs: [
"**/*.java",
"**/*.aidl",
],
visibility: ["//frameworks/base"],
}
如上，将java 和aidl文件都包含进去，记住上面的名字framework-flyscale-sources 后面我们会用到
2）删除系统默认编译：
//framework/base/core/java/Android.bp
package {
// See: http://go/android-license-faq
// A large-scale-change added 'default_applicable_licenses' to import
// all of the 'license_kinds' from "frameworks_base_license"
// to get the below license kinds:
// SPDX-license-identifier-Apache-2.0
// SPDX-license-identifier-BSD
// legacy_unencumbered
default_applicable_licenses: ["frameworks_base_license"],
}
filegroup {
name: "framework-core-sources",
srcs: [
"**/*.java",
"**/*.aidl",
],
exclude_srcs: [
// Remove election toolbar code from build time
"android/service/selectiontoolbar/*.aidl",
"android/service/selectiontoolbar/*.java",
"android/view/selectiontoolbar/*.aidl",

],
visibility: ["//frameworks/base"],
}
filegroup {
name: "IKeyAttestationApplicationIdProvider.aidl",
srcs: ["android/security/keymaster/IKeyAttestationApplicationIdProvider.aidl"],
}
。。。。。。省略3）我们不让系统默认编译新增的文件，那么我们要显示的加入到编译中，修改如下：
framework/base/Android.bp下

现在可以笑了。重新编译记得clean 这样就编译通过了！
