AIDL(Android Inte易做图ce definition language)学习笔记一

一、源码结构：

二、Manifest文件

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.qiao.aidl.test1"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="7" />

    <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:label="@string/app_name"
            android:name=".AIDL_Demo_1Activity" >
            <intent-filter >
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <service android:name="com.qiao.aidl.service.MusicService" android:enabled="true"></service>
    </application>

</manifest>
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.qiao.aidl.test1"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="7" />

    <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:label="@string/app_name"
            android:name=".AIDL_Demo_1Activity" >
            <intent-filter >
                <action android:name="android.intent.action.MAIN" />

</manifest>

三、AIDL文件

package com.qiao.aidl.aidl;

inte易做图ce IServicePlayer{
    void play();
    void pause();
    void stop();
    int getDuration();
    int getCurrentPosition();
    void seekTo(int current);
    boolean setLoop(boolean loop);
}
package com.qiao.aidl.aidl;

inte易做图ce IServicePlayer{
void play();
void pause();
void stop();
int getDuration();
int getCurrentPosition();
void seekTo(int current);
boolean setLoop(boolean loop);
}

四、MusicService

package com.qiao.aidl.service;

import java.io.File;
import java.io.IOException;

import com.qiao.aidl.aidl.IServicePlayer;
import com.qiao.aidl.test1.R;

import android.app.Service;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.Environment;
import android.os.IBinder;
import android.os.RemoteException;

public class MusicService extends Service{

    public static final String TAG = "MusicService";

    public static MediaPlayer mediaPlayer = null;

    public boolean isPause = false;


    @Override
    public void onCreate() {
        // TODO Auto-generated method stub
        super.onCreate();
        //第一种加载音乐文件的方法，即把音乐文件放在res资源文件中
//      mediaPlayer = MediaPlayer.create(getApplicationContext(), R.raw.test);
        //第二种加载音乐文件的方法，读取本地SD卡上的音乐文件
        mediaPlayer = new MediaPlayer();
        try {
            loadMusicFileFromSDCard("光辉岁月_Beyond.mp3");
        } catch (IOException e) {
            System.out.println("文件读取失败");
            e.printStackTrace();
        }
    }

    private void loadMusicFileFromSDCard(String fileName) throws IOException{
        File audioFile = new File("/sdcard/DUOMI
