雖然出現了錯誤，可是在/media/sdb4/aosp/out/target/common/obj/JAVA_LIBRARIES/framework_intermediates/src/core/java/android/service/test/文件夾下出現了二個文件:
IMyTestManager.java     IMyTestManager.P

IMyTestManager.java文件內容以下：
/*
 * 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
{

}

}
IMyTestManager.P文件內容以下：
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）：建立新的系統服務類 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：建立系統服務公開接串口管理類 frameworks/base/core/java/android/service/test/MyTestManager.java緩存

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：將建立的服務添加進ServiceManager 文件：frameworks/base/services/java/com/android/server/SystemServer.javabash

import android.service.test.MyTestManagerService;

private void startOtherServices()函數中
       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：代碼中的Context.MYTEST_SERVICE服務常量添加 路徑：frameworks/base/core/java/android/content/Context.javaapp

/** @hide */
    @StringDef({
AUDIO_SERVICE,
MYTEST_SERVICE,      增長這行代碼在@StringDef註解中

另外還在代碼中
public static final String MYTEST_SERVICE = "mytest";

8：註冊服務 路徑：frameworks/base/core/java/android/app/ContextImpl.java

import android.service.test.IMyTestManager;
import android.service.test.MyTestManager;

在靜態代碼塊中：
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，還要在aosp/external/sepolicy/service_contexts文件中在中間增長一行

(audio u:object_r:system_server_service:s0的下面)

mytest u:object_r:system_server_service:s0

9：我認爲的編譯方式（可能個人理解不正確）

說明編譯成功了，此時須要用模擬器來看看實驗結果。先要編譯SDK。

14：lunch sdk-eng而後再：

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)) ####
編譯完以後會在/media/sdb4/aosp/out/host/linux-x86/sdk/sdk/  目錄下產生一個android-sdk_eng.joe_linux-x86子目錄及zip壓縮文件，這個壓縮文件其實就是android-sdk_eng.joe_linux-x86目錄壓縮而成。之後開發時就能夠用這個子目錄或zip壓縮文件（解壓)以後做爲SDK使用。

15:joe@joe-Aspire-Z3730:/media/sdb4/aosp$ make從新編譯系統以後啓動模擬器，用adb shell啓動shell, 而後root@generic:/system/lib # service list

1.先在framework/base目錄下執行
mmm core/res/      生成framework-res.apk
2.接着在framework/base下繼續執行
mm -B 
便可生成Install: out/target/product/generic/system/framework/framework.jar

簡化方法：

解決了個人問題，不過我簡化了一下：
mmm frameworks/base/core/res/
mmm frameworks/base/

備註： 網上有人說增長了系統服務以後，須要從新編譯再啓動服務，我尚未到這一步，先記錄下來，以備忘記

. 測試
make
make update-api 更新current.xml文件
生成system.imz文件，放到<ANDROID_SDK>/platform/android-20/images/目錄下，
adb shell
service list

還有人說：https://www.2cto.com/kf/201709/687510.html

回到根目錄下執行make update-api,不然編譯不能經過。先編譯framework.jar,而後編譯service.jar,最後編譯本身加mymodule。能夠用mm命令編譯，沒問題後再整編。由於編譯出來的out目錄有boot.art和boot.oat，framework.jar和service.jar不能push調試，因此只能刷整包驗證。
