Question

我正在尝试创建一个聊天应用程序，希望用户在该应用程序中上传图像，并且我正在使用Firebase RealTime数据库存储用户的数据。 taskSnapshot.downloadUrl（）方法已过时，因为我使用了另一种方法将图像上传到Firebase，如文档

所示

https://firebase.google.com/docs/storage/android/upload-files

和此StackOverflow

帖子：taskSnapshot.getDownloadUrl() is deprecated 但是，图像仍未上传到数据库。

我还尝试了诸如清理项目，重建项目，无效和重新启动之类的事情。

这是我用来将图像上传到Firebase RealTime数据库的代码：

    // ImagePickerButton shows an image picker to upload an image for a 
     message
    mPhotoPickerButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
            intent.setType("image/jpeg");
            intent.putExtra(Intent.EXTRA_LOCAL_ONLY, true);
            startActivityForResult(Intent.createChooser(intent, "Complete action using"), RC_PHOTO_PICKER);
        }
    });

，然后在onActivityResults方法中：

@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable 
Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == RC_SIGN_IN) {
        if (resultCode == RESULT_OK) {
            Toast.makeText(MainActivity.this, "Signed-In", 
        Toast.LENGTH_SHORT).show();
        } else if (resultCode == RESULT_CANCELED) {
            Toast.makeText(MainActivity.this, "Signed-In Cancel", 
        Toast.LENGTH_SHORT).show();
            finish();
        } else if (requestCode == RC_PHOTO_PICKER && resultCode == 
          RESULT_OK) {

            Uri selectedUri = data.getData();
            final StorageReference storageReference = mChatPhotosStorageReference.
                    child(selectedUri.getLastPathSegment());
            UploadTask uploadTask = storageReference.putFile(selectedUri);
            Task<Uri> uriTask = uploadTask.continueWithTask(new Continuation<UploadTask.TaskSnapshot, Task<Uri>>() {
                @Override
                public Task<Uri> then(@NonNull Task<UploadTask.TaskSnapshot> task) throws Exception {
                    if (!task.isSuccessful()) {
                        throw task.getException();
                    }

                    return storageReference.getDownloadUrl();
                }
            }).addOnCompleteListener(new OnCompleteListener<Uri>() {
                @Override
                public void onComplete(@NonNull Task<Uri> task) {
                    if (task.isSuccessful()) {
                        Uri downloadUrl = task.getResult();
                        FriendlyMessage message = new FriendlyMessage(null, mUsername, downloadUrl.toString());
                         mMessageDatabaseReference.push().setValue(message);
                    }
                }
            });

使用此文件以字节为单位将照片上传到Firebase存储

            }
