Firebase存储上传进度不准确 [英] Firebase storage upload progress inaccurate

问题描述

onProgress函数存在问题，被addOnProgressListener覆盖.

There is a problem with the onProgress function that is overrided by addOnProgressListener.

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.它只是保持为0.这是我为此的一小段代码:

My problem is that the TaskSnapshot when I try to upload an image does not return the bytes that have been transferred. It just stays at 0. Here is a snippet of code that I have for this:

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:

推荐答案

firebaser此处

以256KB的块为单位来衡量进度.由于您的文件小于该文件，因此它可以容纳一整块，因此进度一口气就从0％跃升到100％.

The progress is measured in chunks of 256KB. Since your file is smaller than that, it fits in one chunk and progress thus jumps from 0% to 100% in one go.

在文件较小和带宽较低的情况下，我们有一个开放的任务来提高进度测量的粒度.

We have an open task to improve the granularity of the progress measurement in the case of smaller files and lower bandwidth connections.
