Android：默认录音

Question

我正在尝试使用以下代码录制音频。

public void onClick(DialogInterface dialog, int id) {
    System.out.println("Inside Audio recording");
    File storageDir = new File(Environment.getExternalStorageDirectory()+ "/filetoupload/");
    if (!storageDir.exists()) {
        storageDir.mkdirs();
    }
    try {
            System.out.println("Inside Audio recording try block");
            imageToStore = new File(storageDir,"" + "audio.3gp");
            Intent intent = new Intent(MediaStore.Audio.Media.RECORD_SOUND_ACTION);
            intent.putExtra(MediaStore.EXTRA_OUTPUT,Uri.fromFile(imageToStore));
            System.out.println("Inside Audio recording path"+ imageToStore);
            startActivityForResult(intent,CAPTURE_AUDIO);
        } catch (Exception e) {
            e.printStackTrace();
            }
        }

}
}

它会打开默认的安卓录音播放器，让我录制音频文件。

所以基本上它会开始默认音频录制，并应在 SD 卡内创建文件夹名称 filetoupload 并将其存储为名称 audio.3gp 但它不是做同样的事情。它将录音存储在设备的默认录音文件夹中或使用其他名称，例如 recording-10555454545.3gp

那么我怎样才能将此音频存储在 SD 卡的特定文件夹中并使用 audio.3gp 名称请帮助。

            }
