实现录音AAC格式，并上传到服务器，然后下载播放。（包括服务器端代码）

这是以前写的一个录音Sample，现在发上来与大家分享。代码并不是全部自己写的，是拿别人的一个应用来改的。

1、使用的三方库：
VoAACEncoder

2、录音部分：
public void startRecord() {
if (!Environment.getExternalStorageState().equals(
android.os.Environment.MEDIA_MOUNTED)) {
Toast.makeText(MainActivity.this, "请插入SD卡！", Toast.LENGTH_SHORT)
.show();
return;
}

try {
// mRecordFileName = Environment.getExternalStorageDirectory()
// .toString()
// + "/testAAC"
// + System.currentTimeMillis()
// + ".aac";

mRecordFileName = Environment.getExternalStorageDirectory()
.toString() + "/testAAC.aac";

fos = new FileOutputStream(mRecordFileName);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
System.out.println("fos = " + fos);
new Thread(new Runnable() {
@Override
public void run() {
VoAACEncoder vo = new VoAACEncoder();
vo.Init(SAMPLERATE, 16000, (short) 1, (short) 1);// 采样率:16000,bitRate:32k,声道数:1，编码:0.raw
// 1.ADTS
int min = AudioRecord.getMinBufferSize(SAMPLERATE,
AudioFormat.CHANNEL_IN_MONO,
AudioFormat.ENCODING_PCM_16BIT);
if (min < 2048) {
min = 2048;
}
byte[] tempBuffer = new byte[2048];
recordInstance = new AudioRecord(MediaRecorder.AudioSource.MIC,
SAMPLERATE, AudioFormat.CHANNEL_IN_MONO,
AudioFormat.ENCODING_PCM_16BIT, min);
recordInstance.startRecording();
isStartRecord = true;
while (isStartRecord) {
int bufferRead = recordInstance.read(tempBuffer, 0, 2048);
byte[] ret = vo.Enc(tempBuffer);
if (bufferRead > 0) {
System.out.println("ret:" + ret.length);
try {
fos.write(ret);
} catch (IOException e) {
e.printStackTrace();
}
}
}
recordInstance.stop();
recordInstance.release();
recordInstance = null;
vo.Uninit();
try {
fos.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}).start();

}


3、上传文件部分
class MyClickListener implements OnTouchListener {
public boolean onTouch(View v, MotionEvent event) {
Log.i("keanbin", "event.getAction() = " + event.getAction());
switch (event.getAction()) {
case MotionEvent.ACTION_UP:
setTalkBtnBackground(false);
// TODO 正常放开，接下来一般做以下事情：发送录音文件到服务器
if (isStartRecord) {
// 停止录音
stopRecord();

Toast.makeText(MainActivity.this, "开始上传文件！",
Toast.LENGTH_SHORT).show();
// 上传文件
HttpOperateUtil
.uploadFile(URL_UPLOAD_FILE, mRecordFileName);
Toast.makeText(MainActivity.this, "上传完文件！",
Toast.LENGTH_SHORT).show();
}
break;

case MotionEvent.ACTION_CANCEL:
setTalkBtnBackground(false);
// TODO 异常放开，接下来一般做以下事情：删除录音文件

// 停止录音
stopRecord();
break;

default:
break;
}
return false;
}

}
使用的工具类：
HttpOperateUtil.java:

package com.example.test_voaacencoder.util;

import java.io.BufferedReader;
import java.io.DataOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

import android.os.Environment;
import android.util.Log;

public class HttpOperateUtil {

public static boolean uploadFile(String uploadUrl, String srcPath) {
String end = "\r\n";
String twoHyphens = "--";
String boundary = "******";
try {
URL url = new URL(uploadUrl);
HttpURLConnection httpURLConnection = (HttpURLConnection) url
.openConnection();
// 设置每次传输的流大小，可以有效防止手机因为内存不足崩溃
// 此方法用于在预先不知道内容长度时启用,没有进行内部缓冲的 HTTP 请求正文的流。
httpURLConnection.setChunkedStreamingMode(128 * 1024);// 128K
// 允许输入输出流
httpURLConnection.setDoInput(true);
httpURLConnection.setDoOutput(true);
httpURLConnection.setUseCaches(false);
// 使用POST方法
httpURLConnection.setRequestMethod("POST");
httpURLConnection.setRequestProperty("Connection", "Keep-Alive");
httpURLConnection.setRequestProperty("Charset", "UTF-8");
httpURLConnection.setRequestProperty("Content-Type",
"multipart/form-data;boundary=" + boundary);

DataOutputStream dos = new DataOutputStream(
httpURLConnection.getOutputStream());
dos.writeBytes(twoHyphens + boundary + end);
dos.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\"; filename=\""
+ srcPath.substring(srcPath.lastIndexOf("/") + 1)
+ "\""
+ end);
dos.writeBytes(end);

// 上传文件内容
FileInputStream fis = new FileInputStream(srcPath);
byte[] buffer = new byte[8192]; // 8k
int count = 0;
// 读取文件
while ((count = fis.read(buffer)) != -1) {
dos.write(buffer, 0, count);
}
fis.close();

dos.writeBytes(end);
dos.writeBytes(twoHyphens + boundary + twoHyphens + end);
dos.flush();

// 服务器返回结果
InputStream is = httpURLConnection.getInputStream();
InputStreamReader isr = new InputStreamReader(is, "utf-8");
BufferedReader br = new BufferedReader(isr);
String result = br.readLine();

// Toast.makeText(this, result, Toast.LENGTH_LONG).show();
Log.i("uploadFile", "uploadFile result = " + result);

try {
dos.close();
} catch (Exception e) {
e.printStackTrace();
// setTitle(e.getMessage());
}
is.close();

return true;

} catch (Exception e) {
e.printStackTrace();
// setTitle(e.getMessage());
}

return false;
}

public static String downLoadFile(String fileUrl, String fileName) {
String fileDir = "";
try {
// 判断SD卡是否存在，并且是否具有读写权限
if (Environment.getExternalStorageState().equals(
Environment.MEDIA_MOUNTED)) {
// 获得存储卡的路径
String sdpath = Environment.getExternalStorageDirectory() + "/";
String savePath = sdpath + "download";
URL url = new URL(fileUrl);
// 创建连接
HttpURLConnection conn = (HttpURLConnection) url
.openConnection();
conn.connect();
// 获取文件大小
int contentLength = conn.getContentLength();
// 创建输入流
InputStream is = conn.getInputStream();

File file = new File(savePath);
// 判断文件目录是否存在
if (!file.exists()) {
file.mkdir();
}
File apkFile = new File(savePath, fileName);
FileOutputStream fos = new FileOutputStream(apkFile);
int count = 0;
// 缓存
byte buf[] = new byte[1024];
// 写入到文件中
do {
int numread = is.read(buf);
// count += numread;
// // 计算进度条位置
// mPercent = (int) (((float) count / contentLength) * 100);
// // 更新进度
// mHandler.sendEmptyMessage(DOWNLOAD_PERCENT);
if (numread <= 0) {
// 下载完成
fileDir = savePath + "/" + fileName;
// if (checkUpdateResult(apkFile)) {
// // 下载成功
//
// } else {
// // 下载失败
// fos.close();
// is.close();
// // throw new RuntimeException("下载文件出错");
// }
break;
}
// 写入文件
fos.write(buf, 0, numread);
} while (true);// !mCancelUpdate);// 点击取消就停止下载.
fos.close();
is.close();
}
} catch (IOException e) {
e.printStackTrace();
}

return fileDir;
}
}

4、播放部分
public void startPlay() {

new Thread(new Runnable() {

@Override
public void run() {

Looper.prepare();
// TODO Auto-generated method stub
String fileUrl = "http://192.168.1.147/upload/testAAC.aac";

String fileName = HttpOperateUtil.downLoadFile(fileUrl,
fileUrl.substring(fileUrl.lastIndexOf("/") + 1));

Log.i
4000
("keanbin", "fileName = " + fileName);
File file = new File(fileName);

if (!file.exists()) {
Toast.makeText(MainActivity.this, "没有音乐文件！", Toast.LENGTH_SHORT)
.show();
return;
}

mMediaPlayer = MediaPlayer.create(MainActivity.this,
Uri.parse(fileName));
mMediaPlayer.setLooping(false);
mMediaPlayer.start();

Looper.loop();
}
}).start();

}
5、服务器端代码：
receive_file.php：

<?php
$target_path = "./upload/";//接收文件目录
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded";
} else{
echo "There was an error uploading the file, please try again!" . $_FILES['uploadedfile']['error'];
}
?>
