AIDL

通常每个应用程序都在他自己的进程内运行，但有时需要在进程之间传递对象（IPC通信）。此时可以通过应用程序UI的方式写一个运行在不同进程中的service。在Android平台中，一个进程通常不能访问其他进程中的内存区域。所以它们需要把对象拆分成操作系统能理解的简单形式，以便伪装成对象跨边界访问。而要完成这些需要AIDL机制。

AIDL（Android接口描述语言）是一个IDL语言，它可以生成一段代码，可以是一个在Android设备上运行的两个进程使用内部通信进程进行交互。如果你想在一个进程中（例如在一个Activity中）访问另一个进程中（例如service）某个对象的方法，你就可以使用AIDL来生成这样的代码来伪装传递各种参数。

要使用AIDL，service需要以AIDL文件的方式提供服务接口，AIDL工具将生成一个相应的java接口，并且在生成的服务器接口中包含一个功能调用的stub（）服务桩类。service的onBind方法会返回实现类的对象，之后你就可以使用它了。

AIDL文件

framework中包含的aidl是在frameworks/base/Android.mk中定义的。该文件定义了两处aidl文件列表。

第一处是给LOCAL_SRC_FILES变量中使用 “+=” 进行赋值，该变量将包含在framework.jar目标中的所有源文件，包括aidl文件和java文件。

第二处是给aidl_files变量使用“:=”赋值符号进行赋值，该变量仅仅包含android.jar目标中所有的aidl文件。

因此，当给Frameworks中添加新的aidl文件时，需要考虑文件是否要公开到SDK中。如果需要，则需要把该文件路径同时添加到以上两个变量中；如果不需要公开到SDK中，则只需要把文件路径添加到LOCAL_SRC_FILES变量中。

在完成这些操作后编译仍会出现问题，此时需要运行,make update-api命令，此时改变的文件是current.txt改变的内容如下：

+ public abstract interface IEneaService implements android.os.IInterface {

+ }

+

+ public static abstract class IEneaService.Stub extends android.os.Binder implements android.os.IEneaService {

+ ctor public IEneaService.Stub();

+ method public android.os.IBinder asBinder();

+ method public static android.os.IEneaService asInterface(android.os.IBinder);

+ method public boolean onTransact(int, android.os.Parcel, android.os.Parcel, int) throws android.os.RemoteException;

+ }

+

这时，如果希望在写的Activity中使用的情况下，需要首先获取服务，这个步骤是通过"ServiceManager.getService()"这个API实现。然后使用service handle来调用service暴露出来的函数。ITestService om = ITestService.Stub.asInterface(ServiceManager.getService("Test"));

下面是个简单的例子：

/*
* HelloServer.java
*/
package com.Test.helloserver;
import android.app.Activity;
import android.os.Bundle;
import android.os.ServiceManager;
import android.os.ITestService;
import android.util.Log;
public class HelloServer extends Activity {
private static final String DTAG = "HelloServer";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

ITestService om = ITestService.Stub.asInterface(ServiceManager.getService("Test"));
try {
Log.d(DTAG, "Going to call service");
om.setValue(20);
Log.d(DTAG, "Service called succesfully");
}
catch (Exception e) {
Log.d(DTAG, "FAILED to call service");
e.printStackTrace();
}
}
}
