虽然出现了错误，可是在/media/sdb4/aosp/out/target/common/obj/JAVA_LIBRARIES/framework_intermediates/src/core/java/android/service/test/文件夹下出现了二个文件:
IMyTestManager.java     IMyTestManager.P

IMyTestManager.java文件内容以下：
/*
 * This file is auto-generated.  DO NOT MODIFY.
 * Original file: frameworks/base/core/java/android/service/test/IMyTestManager.aidl
 */
package android.service.test;
public interface IMyTestManager extends android.os.IInterface
{
/** Local-side IPC implementation stub class. */
public static abstract class Stub extends android.os.Binder implements android.service.test.IMyTestManager
{
private static final java.lang.String DESCRIPTOR = "android.service.test.IMyTestManager";
/** Construct the stub at attach it to the interface. */
public Stub()
{
this.attachInterface(this, DESCRIPTOR);
}
/**
 * Cast an IBinder object into an android.service.test.IMyTestManager interface,
 * generating a proxy if needed.
 */
public static android.service.test.IMyTestManager asInterface(android.os.IBinder obj)
{
if ((obj==null)) {
return null;
}
android.os.IInterface iin = obj.queryLocalInterface(DESCRIPTOR);
if (((iin!=null)&&(iin instanceof android.service.test.IMyTestManager))) {

return true;
}

return true;
}
}
return super.onTransact(code, data, reply, flags);
}
private static class Proxy implements android.service.test.IMyTestManager
{
private android.os.IBinder mRemote;
Proxy(android.os.IBinder remote)
{
mRemote = remote;
}
@Override public android.os.IBinder asBinder()
{
return mRemote;
}
public java.lang.String getInterfaceDescriptor()
{
return DESCRIPTOR;
}
@Override public java.lang.String sayHello() throws android.os.RemoteException
{

}
public java.lang.String sayHello() throws android.os.RemoteException;
public int priFunction() throws android.os.RemoteException;
}
IMyTestManager.P文件内容以下：
out/target/common/obj/JAVA_LIBRARIES/framework_intermediates/src/core/java/android/service/test/IMyTestManager.java: \
  frameworks/base/core/java/android/service/test/IMyTestManager.aidl

4）：建立新的系统服务类 frameworks/base/core/java/android/service/test/MyTestManagerService.javaapi

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：建立系统服务公开接串口管理类 frameworks/base/core/java/android/service/test/MyTestManager.java缓存

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：将建立的服务添加进ServiceManager 文件：frameworks/base/services/java/com/android/server/SystemServer.javabash

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.javaapp

/** @hide */
    @StringDef({
AUDIO_SERVICE,
MYTEST_SERVICE,      增长这行代码在@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文件中在中间增长一行

(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（可能个人理解不正确）

说明编译成功了，此时须要用模拟器来看看实验结果。先要编译SDK。

14：lunch sdk-eng而后再：

joe@joe-Aspire-Z3730:/media/sdb4/aosp$ make sdk
。。。。。

#### make completed successfully (01:02:57 (hh:mm:ss)) ####
编译完以后会在/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。之后开发时就能够用这个子目录或zip压缩文件（解压)以后做为SDK使用。

15:joe@joe-Aspire-Z3730:/media/sdb4/aosp$ make从新编译系统以后启动模拟器，用adb shell启动shell, 而后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 
便可生成Install: out/target/product/generic/system/framework/framework.jar

简化方法：

解决了个人问题，不过我简化了一下：
mmm frameworks/base/core/res/
mmm frameworks/base/

备注：网上有人说增长了系统服务以后，须要从新编译再启动服务，我尚未到这一步，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,不然编译不能经过。先编译framework.jar,而后编译service.jar,最后编译本身加mymodule。能够用mm命令编译，没问题后再整编。由于编译出来的out目录有boot.art和boot.oat，framework.jar和service.jar不能push调试，因此只能刷整包验证。
