1 bindService的启动 2通过AIDL来进行进程间的通信

1：直接写一个接口文件PersonInterface.aidl，文件中的方法就是可以提供给别的进程可以访问的方法。保存后会自动在gen目录下生成PersonInterface.java文件

注意：1:此必须.aidl为后缀名 2:必须显示加包和导入要用到的类，那怕是在同一个包下也要引入

直接上代码：

package org.lzm.android.aidl;
import org.lzm.android.aidl.Person;
interface PersonInterface{
void sayHello();
Person getPerson();
}

自动生成的类PersonInterface.java，此类为自动生成，格式有点臭，我没有去动它，哈哈

static final int TRANSACTION_getPerson = (android.os.IBinder.FIRST_CALL_TRANSACTION + 1);
}
public void sayHello() throws android.os.RemoteException;
public Person getPerson() throws android.os.RemoteException;
}

2：写一个JAVABEAN类且必须实现Parcelable接口

package org.lzm.android.aidl;

import android.os.Parcel;
import android.os.Parcelable;

public class Person implements Parcelable {

private String name;

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public int getAge() {
return age;
}

public void setAge(int age) {
this.age = age;
}

private int age;

public Person(){

}
public Person(Parcel p){
name = p.readString();
age = p.readInt();
}
@Override
public int describeContents() {
// TODO Auto-generated method stub
return 0;
}

@Override
public void writeToParcel(Parcel dest, int flags) {
// TODO Auto-generated method stub
dest.writeString(name);
dest.writeInt(age);
}
static final Parcelable.Creator<Person> CREATOR  = new Creator<Person>() {

@Override
public Person[] newArray(int size) {
// TODO Auto-generated method stub
return new Person[size];
}

@Override
public Person createFromParcel(Parcel source) {
// TODO Auto-generated method stub
return new Person(source);
}
};
}

3： 再定义一个Person.aidl文件

内容很少只有一行代码：parcelable Person;但parcelable 要小写

parcelable Person;

4：关键的server类：PersonService.java

此类中就是你要调用前面PersonInterface.aidl中定义好的方法。这样就可以了。

package org.lzm.android.aidl;

import org.lzm.android.aidl.PersonInterface.Stub;

import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.os.RemoteException;
import android.util.Log;

public class PersonService extends Service {
private static final String TAG = "PersonService";

PersonInterface.Stub mBinder = new Stub() {
@Override
public void sayHello() throws RemoteException {
System.out.println("hello");
}

@Override
public Person getPerson() throws RemoteException {
// TODO Auto-generated method stub
Person p = new Person();
p.setAge(11);
p.setName("lzm");
return p;
}
};
@Override
public IBinder onBind(Intent intent) {
return mBinder;
}
@Override
public void onCreate() {
// TODO Auto-generated method stub
super.onCreate();
Log.i(TAG, "onCreate");
}
@Override
public void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
Log.i(TAG, "onDestroy");
}

}

5：在AndroidManifest.xml中注册你自己实现的Service,此处的intentfilter中的Action要与你在调用bindService方法的第一个参数intent的action一样,如下所示：

<action android:name="org.lzm.android.aidl.PersonInterface"></action> 与bindService(new Intent(""), conn, BIND_AUTO_CREATE);

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="org.lzm.android.aidl"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="8" />

<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".AIDLDemo"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service android:name="PersonService"
android:process=":remote">
<intent-filter>
<action android:name="org.lzm.android.aidl.PersonInterface"></action>
</intent-filter>
</service>
</application>
</manifest>

6.这样就可以了在运行之。
