Firebase存储上传进度不准确

Question

addOnProgressListener覆盖了onProgress函数的问题.

我的问题是,当我尝试上传图像时,T​​askSnapshot不会返回已传输的字节.它只是保持在0.这是我的代码片段:

StorageReference myStorageRef = momentsStorageRef.child(momentID + ".jpeg");

UploadTask uploadTask = myStorageRef.putBytes(data, new StorageMetadata.Builder()
       .setContentType("image/jpeg")
       .build());



uploadTask.addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
   @Override
   public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
       int bytesTransferred = (int) taskSnapshot.getBytesTransferred();
       int totalBytes = (int) taskSnapshot.getTotalByteCount();



       int progress = (100 *  bytesTransferred) / totalBytes ;
       Log.v(TAG, "Bytes transferred: " + taskSnapshot.getBytesTransferred());
       Log.v(TAG, "TotalBytes: " + totalBytes);
       Log.v(TAG, "Upload is: " + progress + "% done");
       mBuilder.setProgress(100, progress, false);


       mNotifyManager.notify(APPLICATION_NOTIFICATION_ID, mBuilder.build());
   }
})

这是logCat:

进度以256KB的块为单位进行测量.由于您的文件小于该文件,因此它适合一个块,因此进度一次从0%跳到100%.

我们有一项开放式任务,可以在较小文件和较低带宽连接的情况下改进进度测量的粒度.
