IMyTestManager.java IMyTestManager.P
IMyTestManager.java文件内容如下：
/*
* This file is auto-generated. DO NOT MODIFY.

*/
package android.service.test;
public interface IMyTestManager extends android.os.IInterface

/** Construct the stub at attach it to the interface. */
public Stub()
{
this.attachInterface(this, DESCRIPTOR);
}
/**

*/

return null;

IMyTestManager.P文件内容如下：

frameworks/base/core/java/android/service/test/IMyTestManager.aidl
4）：创建新的系统服务类 frameworks/base/core/java/android/service/test/MyTestManagerService.java
package android.service.test;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.os.RemoteException;
import android.util.Log;
public class MyTestManagerService extends IMyTestManager.Stub{
private static final String TAG = "MyTestManagerService";
private Context mContext;
public MyTestManagerService(Context context){
mContext = context;
}
@Override
public String sayHello() throws RemoteException{
Log.d(TAG,"sayHello()");
return "Hello AIDL";
}
@Override
public int priFunction() throws RemoteException{
Log.d(TAG,"priFunction()");
return 0;
}
}
5：创建系统服务公开接串口管理类 frameworks/base/core/java/android/service/test/MyTestManager.java
package android.service.test;
import android.os.RemoteException;
import android.util.Log;
import android.service.test.IMyTestManager;
public class MyTestManager{
private static final TAG="MyTestManager";
private IMyTestManager mService;
public MyTestManager(IMyTestManager service){
mService = service;
}
public String sayHello() throws RemoteException{
Log.d(TAG,"sayHello()");
return mService.sayHello();
}
}
6：将创建的服务添加进ServiceManager 文件：frameworks/base/services/java/com/android/server/SystemServer.java
import android.service.test.MyTestManagerService;
private void startOtherServices()函数中
AudioService audioService = null;
MyTestManagerService mTestService = null;
。。。。。。
try{
Slog.i(TAG,"MyTestManager Service");
mTestService = new MyTestManagerService(context);
ServiceManager.addService(Context.MYTEST_SERVICE,mTestService);
}catch(Throwable e){
reportWtf("starting MyTestManager",e);
}
7：代码中的Context.MYTEST_SERVICE服务常量添加 路径：frameworks/base/core/java/android/content/Context.java
/** @hide */
@StringDef({
AUDIO_SERVICE,
MYTEST_SERVICE, 增加这行代码在@StringDef注解中
另外还在代码中
public static final String MYTEST_SERVICE = "mytest";
8：注册服务 路径：frameworks/base/core/java/android/app/ContextImpl.java
import android.service.test.IMyTestManager;
import android.service.test.MyTestManager;
在静态代码块中：
registerService(AUDIO_SERVICE, new ServiceFetcher() {
public Object createService(ContextImpl ctx) {
return new AudioManager(ctx);
}});
registerService(MYTEST_SERVICE,new ServiceFetcher(){
public Object createService(ContextImpl ctx){
IBinder iBinder = ServiceManager.getService(Context.MYTEST_SERVICE);
if(iBinder == null){
return null;
}
IMyTestManager service = IMyTestManager.Stub.asInterface(iBinder);
return new MyTestManager(service);
}
});
另外，还要在aosp/external/sepolicy/service_contexts文件中在中间增加一行
(audio u:object_r:system_server_service:s0的下面)
mytest u:object_r:system_server_service:s0
9：我认为的编译方式（可能我的理解不正确）

说明编译成功了，此时需要用模拟器来看看实验结果。先要编译SDK。
14：lunch sdk-eng然后再：
joe@joe-Aspire-Z3730:/media/sdb4/aosp$ make sdk
。。。。。
Package SDK: out/host/linux-x86/sdk/sdk/android-sdk_eng.joe_linux-x86.zip

#### make completed successfully (01:02:57 (hh:mm:ss)) ####
编译完之后会在/media/sdb4/aosp/out/host/linux-x86/sdk/sdk/ 目录下产生一个android-sdk_eng.joe_linux-x86子目录及zip压缩文件，这个压缩文件其实就是android-sdk_eng.joe_linux-x86目录压缩而成。以后开发时就可以用这个子目录或zip压缩文件（解压)之后作为SDK使用。
15:joe@joe-Aspire-Z3730:/media/sdb4/aosp$ make重新编译系统之后启动模拟器，用adb shell启动shell, 然后root@generic:/system/lib # service list
26 mytest: [android.service.test.IMyTestManager]
针对步骤9中出现的错误，网上有人说：https://bbs.csdn.net/topics/370150557
1.先在framework/base目录下执行
mmm core/res/ 生成framework-res.apk
2.接着在framework/base下继续执行
mm -B
即可生成Install: out/target/product/generic/system/framework/framework.jar
简化方法：
解决了我的问题，不过我简化了一下：
mmm frameworks/base/core/res/
mmm frameworks/base/
备注： 网上有人说增加了系统服务之后，需要重新编译再启动服务，我还没有到这一步，先记录下来，以备忘记
. 测试
make
make update-api 更新current.xml文件
生成system.imz文件，放到<ANDROID_SDK>/platform/android-20/images/目录下，
adb shell
service list
还有人说：https://www.2cto.com/kf/201709/687510.html
回到根目录下执行make update-api,否则编译不能通过。先编译framework.jar,然后编译service.jar,最后编译自己加mymodule。可以用mm命令编译，没问题后再整编。因为编译出来的out目录有boot.art和boot.oat，framework.jar和service.jar不能push调试，所以只能刷整包验证。
