如何玩歌的Andr​​oid - PhoneGap的 [英] How to play song in Android - phonegap

问题描述

一个月前，我开始用的PhoneGap，HTML5，CSS3和jQtouch工作。 我工作的一个应用程序，我需要在应用程序中播放声音。我有这个任务的一个严重问题。 首先，我发现我可以使用新媒体（...）函数通过PhoneGap的播放.mp3文件。我不知道.wav文件，我可以玩那些？ 其次我发现，文件必须小于30秒，是这样吗？ 第三，我不能找到合适的地方，我的声音文件。我的项目结构如下：

A month ago I started working with phonegap, html5, css3 and jQtouch. I am working on an application and I need to play sound in the application. I have a serious problem with this task. First I've found out that I can play .mp3 files through phonegap using the new Media(...) function. I am not sure about .wav files, can I play those? Second I've found that files must be less than 30 sec, is this so? Third I can't find the right place for my sound files. My project structure is the following:

project
-- src
-- gen
-- assets
-- -- www
-- -- DANCE.mp3
-- -- jqtouch
-- -- -- (some folders and files)
-- -- phonegap.js
-- libs
-- res

我已经试过将在WWW文件夹中的文件并创建一个新的名为音频。这一切都不给我我想要的东西。 我用这$ C $下执行歌曲：

I've tried placing the file in 'www' folder and creating a new one called 'audio'. None of this gave me what I wanted. I am using this code for executing the song:

function playStream() {
    mp3file = new Media("DANCE.mp3",
            function() {
                alert("playAudio():Audio Success");
            },
                function(err) {
                    alert(err);
            }
            );
          mp3file.play();
}

我采用Android 2.1模拟器，我已经试过2.2也没有成功。 我希望我是清楚。 我期待着您的回音。 此致， 米哈伊尔者velikov

I use Android 2.1 Simulator and I've tried 2.2 as well without success. I hope I was clear enough. I am looking forward to hearing from you. Yours, Mihail Velikov

推荐答案

的PhoneGap为Android可以让您保存在两个地方的本地音频文件：  android_asset：文件名必须以/android_asset/sound.mp3  SD卡：文件名是刚sound.mp3

PhoneGap for Android lets you store local audio files in two places: android_asset: file name must start with /android_asset/sound.mp3 sdcard: file name is just sound.mp3

如果你把你的DANCE.mp3文件在项目的资产目录，则可以使用路径播放：

If you place your DANCE.mp3 file in your project's assets directory, then you can play it using the path:

mp3file = new Media("/android_asset/DANCE.mp3",
        function() {
            alert("playAudio():Audio Success");
        },
            function(err) {
                alert(err);
        }
        );
      mp3file.play();

（你可以阅读在Android PhoneGap的源源AudioPlayer.java，看看它是如何工作。）

(You can read the source for AudioPlayer.java in the Android PhoneGap sources to see how this works.)
