如何在firebase中上传多个图像

Question

i want to upload images in firebase from the four boxes and getdownload url for each

我正在编写一个应用来测试Firebase，用户可以在其中上传带有图片的产品。我在上传时遇到问题，因为图片已存储，但未链接到产品（图像数组未传递？），并且LeakCanary发出内存不足错误的信号。感谢所有帮助和投入。

这是我的产品型号

        final ProgressDialog mDialog = new ProgressDialog(this);
        mDialog.setMessage("Uploading....");
        mDialog.show();

    newFood = new Food();
            final String imageName = UUID.randomUUID().toString();
            final StorageReference imageFolder = storageReference.child("images/" + Common.imgFront.getLastPathSegment());
            final StorageReference imageFolder1 = storageReference.child("images/" + Common.imgBack.getLastPathSegment());
            final StorageReference imageFolder2 = storageReference.child("images/" + Common.imgRight.getLastPathSegment());
            final StorageReference imageFolder3 = storageReference.child("images/" + Common.imgLeft.getLastPathSegment());

            imageFolder.putFile(saveUri)
                    .addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {


                        @Override
                        public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {

                            //   Toast.makeText(FileUpload.this, "Uploaded !!!", Toast.LENGTH_SHORT).show();
                            imageFolder.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {

没有使用Firebase存储同时上传或下载多个图像的API。  You can check a workaround on this other stack overflow question
