android framework service开发原理，以震动模块为例进行讲解
1.先在frameworks\base\core\java\android\os文件夹下面编写开发aidl文件，比如IVibratorService.java
package android.os;
/** {@hide} */
interface IVibratorService
{
boolean hasVibrator();
void vibrate(int uid, String opPkg, long milliseconds, int usageHint, IBinder token);
void vibratePattern(int uid, String opPkg, in long[] pattern, int repeat, int usageHint, IBinder token);
void cancelVibrate(IBinder token);
}
2.将编写好的aidl文件在frameworks\base下面的Android.mk文件中注册。
core/java/android/os/IProcessInfoService.aidl \
core/java/android/os/IProgressListener.aidl \
core/java/android/os/IPowerManager.aidl \
core/java/android/os/IRecoverySystem.aidl \
core/java/android/os/IRecoverySystemProgressListener.aidl \
core/java/android/os/IRemoteCallback.aidl \
core/java/android/os/ISchedulingPolicyService.aidl \
core/java/android/os/IUpdateLock.aidl \
core/java/android/os/IUserManager.aidl \
core/java/android/os/IVibratorService.aidl \
core/java/android/os/IDisplayDeviceManagementService.aidl \
core/java/android/os/IRkDisplayDeviceManagementService.aidl \
core/java/android/security/IKeystoreService.aidl \
3.在frameworks\base\services\core\java\com\android\server的目录下实现aidl的代理服务类VibratorService.java，内容如下：

6.同时也要将这个服务定义在Context.java和注册到ContextImpl.java中去，供上层调用该服务。
frameworks\base\core\java\android\content下面的Context.java类中去定义该服务 /**
* Use with {@link #getSystemService} to retrieve a {@link
* android.os.Vibrator} for interacting with the vibration hardware.
*
* @see #getSystemService
* @see android.os.Vibrator
*/
public static final String VIBRATOR_SERVICE = "vibrator";
然后注册到\frameworks\base\core\java\android\app下面ContextImpl.java类中去注册，内容如下：

上面就可以简单的实现java层的业务功能，如果不需要涉及到c++层的东西，上面创建一个功能服务就完成了，如果需要调用底层库和硬件设备打交道，就需要实现jni层的服务调用。
7.接着实现jni部分功能，先开发jni实现底层c++的业务代码类com_android_server_VibratorService.cpp，内容如下：
