在Android的Phonegap应用程序上播放声音 [英] Play sound on Phonegap app for Android
问题描述
我尝试播放mp3文件。这个工作，如果我改变的路径到本地网络服务器上的文件，但如果我在Android设备上运行这个声音不播放，没有显示错误。
I try to play an mp3 file. This works if I change the path to the file on my local webserver, but if I run this on an Android device the sound is not played and no error is shown.
我很相信mp3文件没有找到，但我仍然不知道如何解决它。
I am pretty shure that the mp3 file is not found, but I still don't know how to fix it.
这是 Html
<body>
<audio id="successSound" src="/android_asset/www/sound/successSound.mp3" type="audio/mpeg" ></audio>
<audio id="errorSound" src="/android_asset/www/sound/errorSound.mp3" type="audio/mpeg" ></audio>
<!-- some more UI -->
</body>
这是 Javascript
document.getElementById('errorSound').play();
是文件结构
phonyapp
`-- www
`-- index.html
|-- sound
| |-- errorSound.mp3
| `-- successSound.mp3
|-- res
`-- spec
修改1
我尝试了
<audio id="successSound" src="sound/successSound.mp3" type="audio/mpeg" ></audio>
这在我的本地网络服务器上使用chrome，但在Android上不行。
This worked in chrome on my local webserver but not on Android.
我尝试了
<audio id="successSound" src="http://html5multimedia.com/media/sayHello.mp3" type="audio/mpeg" ></audio>
这工作，但我需要获取本地文件。
This worked, but I need to get local files playing
推荐答案
HTML5 API提供的播放方法对于播放网络上可用的媒体文件非常有用。 Phonegap提供媒体插件来播放本地媒体文件。我检查了您的代码，并通过进行以下更改成功地播放声音。请检查您的结尾。
The play method which the HTML5 API provides is useful for playing media files available on the web. Phonegap provides the media plugin to play local media files. I checked out your code and played the sound successfully by making the following changes. Please check at your end.
1.将以下行添加到config.xml中
1.Add the following line to config.xml
<gap:plugin name="org.apache.cordova.media" />
2.更换index.html中的行
2.Replace the lines in index.html
<button onclick="document.getElementById('successSound').play()">Play successSound local</button>
<button onclick="document.getElementById('errorSound').play()">Play errorSound local</button>
<button onclick="playAudio('successSound')">Play successSound local</button>
<button onclick="playAudio('errorSound')">Play errorSoundlocal</button>
3.将以下函数添加到js / index.js
3.Add the following function to js/index.js
function playAudio(id) {
var audioElement = document.getElementById(id);
var url = audioElement.getAttribute('src');
var my_media = new Media(url,
// success callback
function () { console.log("playAudio():Audio Success"); },
// error callback
function (err) { console.log("playAudio():Audio Error: " + err); }
);
// Play audio
my_media.play();
}
