java - 如何将音频(3gp)文件上传到firebase存储？

Question

EDIT: I have added in 'recRef' ".3gp" at the end of the reference and now when I use the emulator it uploads as .3gp file of 0KB and external device still uploads an "application/octet-stream" file (weight 0KB).

我对我的应用进行了记录 Activity ，但无法将其正确上传到 Firebase 存储。我尝试根据谷歌发布的图像上传示例构建一个上传过程，它上传一个空文件(0KB，类型“application/octet-stream”)。录制过程运行良好，我制作了一个播放按钮来检查它，所以我知道这只是一个问题，我不知道如何将其正确上传到云端。

欢迎大家使用我的git弹出记录 Activity :https://github.com/tidharon/Popup-Record-Window-App

这是我的上传代码:

recRef = storage.getReference(lastAct + " Records").child(lastTitle);
                metadata = new StorageMetadata.Builder().setCustomMetadata(lastID, outputFile).build();


                ByteArrayOutputStream baos = new ByteArrayOutputStream();
                byte[] daata = baos.toByteArray();
                uploadTask = (UploadTask) recRef.putBytes(daata, metadata).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {
                    @Override
                    public void onComplete(@NonNull Task<UploadTask.TaskSnapshot> task) {
                        recURL = recRef.toString();
                        getIntent().putExtra("recURL", recURL);
                    }
                });

recRef 是一个 StorageReference 元素。元数据是 StorageMetadate 元素。lastID 是连接到记录的文本文档的 ID。outputFile是存储记录的目录

这是录制过程的准备工作:

outputFile = Environment.getExternalStorageDirectory().getAbsolutePath() + ("/" + lastAct + " | " + lastID + " | " + date + ".3gp");
    myAudioRecorder = new MediaRecorder();
    myAudioRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
    myAudioRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
    myAudioRecorder.setAudioEncoder(MediaRecorder.OutputFormat.AMR_NB);
    myAudioRecorder.setOutputFile(outputFile);

提前致谢!

使用此命令检查导致问题的原因

.addOnFailureListener(new OnFailureListener() {
                        @Override
                        public void onFailure(@NonNull Exception e) {
                            Toast.makeText(MyContext, e.toString(), Toast.LENGTH_LONG).show();
                        }
                    })

代码中的 addOnCompleteListener 关闭后
