android录音开发问题<记录1>:AudioRecord录制的音频文件如何用MediaPlayer类读取

ContentValues values = new ContentValues(3);
		long current = System.currentTimeMillis();
		values.put(MediaColumns.TITLE, "My Audio record");
		values.put(MediaColumns.DATE_ADDED, (int) (current / 1000));
		values.put(MediaColumns.MIME_TYPE, "audio/mp3");
		values.put(MediaColumns.DATA, file.getAbsolutePath());
		ContentResolver contentResolver = getContentResolver();
		Uri base = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
		Uri newUri = contentResolver.insert(base, values);
		sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, newUri));
		pathUri = file.getAbsolutePath();
		//读取音频文件的数据
		BufferedInputStream bufferIn;
		try {
			bufferIn = new   BufferedInputStream(new FileInputStream(pathUri));
			Log.v(TAG, "打开文件的路径：" + pathUri);
			byte[] buffer = new byte[1024];
			int length=-1;
			while(true){
				length=bufferIn.read(buffer);
				if(length <=0){
					break;
				}
				//这样就得到数据了，存在buffer中，有length个
			}
			Log.e(TAG, buffer.toString());
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
