<span style="font-size:18px;"><span style="font-size:18px;">项目中，新需求要求可以录音，同时转换成mp3格式传到服务器。这其中遇到了不少坑，接下来慢慢详谈。首先录音可以使用MediaPlayer这个类，直接展示代码 具体demo，下载地址最后会给出。然后android默认录音时.raw格式的，此时我们应该将raw格式的文件转化成mp3格式的。这里我们用到FLameUtils，值得一提的就是flame.jar,和libmp3lame.so文件。
1.最好是放在main文件夹下的jniLibs下
2.要在gradle.properties下加入如下代码：android.useDeprecatedNdk
允许ndk开发
3.当然不要忘记加入如下权限：
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />

然后，实际测试中，发现有的部分手机cpu是64位的，然而上面的so文件是没有64位的，推荐一个第三方，简单易用https://github.com/GavinCT/AndroidMP3Recorder
