如何从 android URI 获取绝对音频路径

Question

Uri 返回目录路径，我需要实现一个代码来获取音频文件并在 MediaPlayer 上播放该音频。我认为 MediaPlayer 需要绝对路径。

 Intent intent;
    intent = new Intent();
    intent.setAction(Intent.ACTION_GET_CONTENT);
    intent.setType("audio/*");
    startActivityForResult(Intent.createChooser(intent,"Select Audio"), 3);

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);
    if((requestCode == 3) && (resultCode == RESULT_OK) && (data != null)){
            if ((data != null) && (data.getData() != null)){
                //this code returns content directory path
                String getAudioPath=data.getData().toString();

            }
        }
    };
Log:

//write to use this 
String getAudioPath=data.getData().getPath().toString();

 String getAudioPath=data.getData().toString();
