Android :默认音频记录

Question

我试图用下面的代码录制音频。

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();
            }
        }

}
}

它将打开默认的android录音播放器，让我记录音频文件。

因此，基本上，它将启动默认的音频记录，并应该在SD卡中创建文件夹名filetoupload，并将其存储为名称audio.3gp，但它不会这样做。它将记录存储在设备中的默认记录文件夹中，或以其他名称(如recording-10555454545.3gp )存储。

所以，我如何能够存储这个音频在SD卡的特定文件夹和与Audio.3gp的名称，请帮助。

                    fis.close();

                        System.out.println("you Audio path"+fileuri.getpath)


                } catch (IOException e) {

            }
