android AudioTrack不能播放awr(4)

                //byte[] buffer = new byte[bufferSize]; 

                //开始录制

                record.startRecording(); 

                int r = 0; //存储录制进度

                //定义循环，根据isRecording的值来判断是否继续录制

                while(isRecording){ 

                    //从bufferSize中读取字节，返回读取的short个数

                    //这里老是出现buffer overflow，不知道是什么原因，试了好几个值，都没用，TODO：待解决

                    int bufferReadResult = record.read(buffer, 0, buffer.length); 

                    //循环将buffer中的音频数据写入到OutputStream中

                    for(int i=0; i<bufferReadResult; i++){ 

                        dos.writeShort(buffer[i]); 

                    }

//                    fos.write(tmpBuf, 0, bufferReadResult); 

//                    fos.flush(); 

                    publishProgress(new Integer(r)); //向UI线程报告当前进度
