Question

我想播放本地存储音频，但在编辑器中它显示为变量，我收到以下错误。

 Refranceerror:can’t find variable:Media
 Refranceerror: can’t find Media at file://android_assets/www/ Over_the_horizon.mp3

我将empreitions放在mainfest文件中，pkugin放在config

中

Answer 1

我有相关的代码播放音频并且运行良好。希望这会对你有所帮助。您可以将音频文件添加到文件夹中，并在res文件夹下将其命名为raw。

通过编码：在您要播放音频的班级中添加此代码：

//*************** Will play sound *******************************
          private void play_sound(){
        //set media player
final MediaPlayer mediaplayer=MediaPlayer.create(MainActivity.this,R.raw.youraudio);  
        mediaplayer.start();
        mediaplayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
            public void onCompletion(MediaPlayer mp) {
                mp.release();
            }
        });
    }

Answer 2

试试这个简单的代码：

          private void sound(){
final MediaPlayer mediaplayer=MediaPlayer.create(MainActivity.this,R.raw.audio);  
        mediaplayer.start();
        mediaplayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
            public void onCompletion(MediaPlayer mp) {
                mp.release();
            }
        });
    }

在eclipse android中播放音频不起作用
