Question

（对不起我的英文）（对不起，如果这个问题无关紧要，我是编程的新手）所以我正在制作一个聊天应用程序但是当我尝试发送照片时它不发送，只有我发送它两次它在db中保存。

以下是我在logcat中收到的警告：

这是代码：

protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == RC_PHOTO_PICKER && resultCode == RESULT_OK) 
    {
        Uri selectedImageUri = data.getData();
        StorageReference photoRef = mSRreference.child(selectedImageUri.toString());
        photoRef.putFile(selectedImageUri);
        photoRef.getDownloadUrl().addOnSuccessListener(
            new OnSuccessListener<Uri>()

            @Override
            public void onSuccess(Uri uri)
            {
                Message m = new Message(null, mUsername, uri.toString());
                mDbReference.push().setValue(m);
            }
        );
    }
}

这里

Answer 1

this Article返回putFile()，最终表明该文件已成功上传。您需要使用该任务。您似乎已经熟悉了任务，因为您已经使用getDownloadUrl（）返回的任务来确定该数据何时可用。

Answer 2

fabs

这将完成你的工作。
