要播放MediaStore.Audio.Media条目，可以使用MediaPlayer类来实现。下面是一个示例代码：

import android.content.ContentResolver;
import android.content.Context;
import android.database.Cursor;
import android.media.MediaPlayer;
import android.net.Uri;
import android.provider.MediaStore;
import android.util.Log;

public class MediaPlayerHelper {

    private static final String TAG = "MediaPlayerHelper";
    private Context mContext;
    private MediaPlayer mMediaPlayer;

    public MediaPlayerHelper(Context context) {
        mContext = context;
        mMediaPlayer = new MediaPlayer();
    }

    public void playAudioFromMediaStore(Uri mediaUri) {
        try {
            // 设置数据源
            mMediaPlayer.setDataSource(mContext, mediaUri);
            // 准备和开始播放音频
            mMediaPlayer.prepare();
            mMediaPlayer.start();
        } catch (Exception e) {
            Log.e(TAG, "playAudioFromMediaStore: " + e.getMessage());
        }
    }

    public void stopAudio() {
        if (mMediaPlayer.isPlaying()) {
            mMediaPlayer.stop();
        }
    }

    public void releaseMediaPlayer() {
        mMediaPlayer.release();
        mMediaPlayer = null;
    }

    public Uri getMediaUri(String audioTitle) {
        ContentResolver contentResolver = mContext.getContentResolver();
        Uri mediaUri = null;
        String[] projection = {MediaStore.Audio.Media._ID};
        String selection = MediaStore.Audio.Media.TITLE + "=?";
        String[] selectionArgs = {audioTitle};
        Cursor cursor = contentResolver.query(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, projection, selection, selectionArgs, null);
        if (cursor != null && cursor.moveToFirst()) {
            int columnIndex = cursor.getColumnIndex(MediaStore.Audio.Media._ID);
            long mediaId = cursor.getLong(columnIndex);
            mediaUri = Uri.withAppendedPath(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, String.valueOf(mediaId));
            cursor.close();
        }
        return mediaUri;
    }
}

使用方法：

// 创建MediaPlayerHelper实例
MediaPlayerHelper mediaPlayerHelper = new MediaPlayerHelper(context);
// 获取音频的Uri
Uri mediaUri = mediaPlayerHelper.getMediaUri("audio_title");
// 播放音频
mediaPlayerHelper.playAudioFromMediaStore(mediaUri);
// 停止音频播放
mediaPlayerHelper.stopAudio();
// 释放MediaPlayer资源
mediaPlayerHelper.releaseMediaPlayer();

注意：需要在AndroidManifest.xml文件中添加以下权限：

这是一个简单的示例，你可以根据自己的需求进行修改和扩展。
