I am working in android. How can I record an audio file through microphone, and how can I save the recorded file in the emulator?

推荐答案

在Android中录制音频很容易.你需要做的是:

It is easy to record audio in Android. What you need to do is:

1) 为媒体记录类创建对象:MediaRecorder recorder = new MediaRecorder();

2)在模拟器中，您无法将录制的数据存储在内存中，因此您必须将其存储在SD卡上.因此，首先检查 SD 卡的可用性:然后使用以下代码开始录制.

1) Create the object for media record class : MediaRecorder recorder = new MediaRecorder();

2) In the emulator, you're unable to store the recorded data in memory, so you have to store it on the SD Card. So, first check for the SD Card availability: then start recording with the following code.

String status = Environment.getExternalStorageState();
if(status.equals("mounted")){
   String path = your path;
}

recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(path);
recorder.prepare();
recorder.start();

3)要停止，请覆盖活动的停止方法

3) To stop, override stop method of activity

 recorder.stop();
 recorder.release();
