java.io.FileNotFoundException: open failed: EISDIR (Is a directory)
问题
我正在尝试在Android Studio的钢琴应用中使用MediaRecorder录制音频。在寻找关于如何保存文件的答案时，我发现getExternalPublicDirectory已被弃用，所以我使用了context.getExternalFilesDir(null).getAbsolutePath();。现在，当我运行应用并点击录制按钮时，在mediaRecorder.prepare();这一行中出现错误java.io.FileNotFoundException: open failed: EISDIR（是一个目录）.. 请帮忙！
private void startRecording() throws IOException {
try {
String path = context.getExternalFilesDir(null).getAbsolutePath();
audioFile = new File(path);
} catch (Exception e) {
Log.e("错误标签", "外部存储访问错误" + e.getMessage());
return;
}
mediaRecorder = new MediaRecorder();
mediaRecorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT);
mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
mediaRecorder.setOutputFile(audioFile.getAbsolutePath());
mediaRecorder.prepare();
mediaRecorder.start();
}

I am trying to record audio in my Piano app in android studio using MediaRecorder. After searching for answers on how to save the file as getExternalPublicDirectory is deprecated so i used context.getExternalFilesDir(null).getAbsolutePath(); . Now when i run the app and hit the record button , i get this error java.io.FileNotFoundException: open failed: EISDIR (Is a directory) in the line mediaRecorder.prepare(); .. Please Help!!
private void startRecording() throws IOException {
try {
String path = context.getExternalFilesDir(null).getAbsolutePath();
audioFile = new File(path);
} catch (Exception e) {
Log.e("Error Tag", "external storage access error " + e.getMessage());
return;
}
mediaRecorder = new MediaRecorder();
mediaRecorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT);
mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
mediaRecorder.setOutputFile(audioFile.getAbsolutePath());
mediaRecorder.prepare();
mediaRecorder.start();

收到预期的java.io.FileNotFoundException: open failed: EISDIR (Is a directory)错误，因为您提供给setOutputFile()的路径指向了一个目录而不是要保存记录数据的文件。
文档中已经很清楚地说明了，
> 设置要生成的输出文件的路径。
请尝试修复您的路径，
String dirPath = context.getExternalFilesDir(null).getAbsolutePath();
String filePath = dirPath + "/recording";
audioFile = new File(filePath);
英文:
Getting java.io.FileNotFoundException: open failed: EISDIR (Is a directory) is what expected since the path that you're providing to setOutputFile() points to a directory and not a file to save the recorded data.
The documentation is clear,
> Sets the path of the output file to be produced.
Try and fix your path,
String dirPath = context.getExternalFilesDir(null).getAbsolutePath();
String filePath = direPath + "/recording";
audioFile = new File(filePath);
