我对整个Firebase存储概念还不熟悉。
我做了一点研究，发现了这个滑翔机。用于将图像添加到imageView。现在它给了我这个错误。
我该怎么补救？
还有别的办法吗

这里是代码

StorageReference mStorageRef = FirebaseStorage.getInstance().getReference();
final StorageReference imgRef = mStorageRef.child("images/img.jpg");
final long ONE_MEGABYTE = 1024*1024;

imgRef.getBytes(ONE_MEGABYTE).addOnSuccessListener(new OnSuccessListener<byte[]>() {
    @Override
    public void onSuccess(byte[] bytes) {
        Glide.with(Cari.this).load(imgRef).diskCacheStrategy(DiskCacheStrategy.ALL).into(kuryerImg);
    }
}).addOnFailureListener(new OnFailureListener() {
    @Override
    public void onFailure(@NonNull Exception e) {

    }
});

使用FirebaseImageLoader

Glide.with(this /* context */)
    .using(new FirebaseImageLoader())
    .load(storageReference)
    .into(imageView);

我有另一个办法来解决这个问题。
你可以得到图片的下载地址。这是谷歌指南中的代码。

StorageReference storageRef = 
  FirebaseStorage.getInstance().getReference();    
 storageRef.child("users/me/profile.png").getDownloadUrl()
.addOnSuccessListener(new OnSuccessListener<Uri>() {
@Override
public void onSuccess(Uri uri) {
    // Got the download URL for 'users/me/profile.png'
    })
.addOnFailureListener(new OnFailureListener() {
  @Override
  public void onFailure(@NonNull Exception exception) {
    // Handle any errors
   }
});

如果你需要一个指南来下载图像到你的设备上，这里有一个Stackoverflow链接：Download Image from URL

使用通用加载器，而不是使用滑翔，它加载图像比滑翔快

DisplayImageOptions defaultOptions = new DisplayImageOptions.Builder()
        .cacheOnDisc(true).cacheInMemory(true)
        .imageScaleType(ImageScaleType.EXACTLY)
        .displayer(new FadeInBitmapDisplayer(300)).build();

ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(
        getApplicationContext())
        .defaultDisplayImageOptions(defaultOptions)
        .memoryCache(new WeakMemoryCache())
        .discCacheSize(100 * 1024 * 1024).build();

ImageLoader.getInstance().init(config);

final ImageLoader imageLoader = ImageLoader.getInstance();

final DisplayImageOptions options = new DisplayImageOptions.Builder().cacheInMemory(true)
        .cacheOnDisc(true).resetViewBeforeLoading(true)
        .showImageForEmptyUri(R.mipmap.preview)
        .showImageOnFail(R.mipmap.preview)
        .build();

 mdatabase.child(Table_item).addValueEventListener(new ValueEventListener() {

    @Override
    public void onDataChange(DataSnapshot dataSnapshot) {
        Map map = (Map) dataSnapshot.getValue();
        String image1 = (String) map.get("imagename");
        String image2 = (String) map.get("image2name");
        imageLoader.displayImage(ImageView1, image1, options, new ImageLoadingListener() {

            @Override
            public void onLoadingStarted(String imageUri, View view) {

            }

            @Override
            public void onLoadingFailed(String imageUri, View view, FailReason failReason) {
                progressBar.setVisibility(View.GONE);
            }

            @Override
            public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {

            }

            @Override
            public void onLoadingCancelled(String imageUri, View view) {
                progressBar.setVisibility(View.GONE);
            }
        });
        imageLoader.displayImage(ImageView2, image2name, options, new ImageLoadingListener() {
            @Override
            public void onLoadingStarted(String imageUri, View view) {

            }

            @Override
            public void onLoadingFailed(String imageUri, View view, FailReason failReason) {
                progressBar.setVisibility(View.GONE);
            }

            @Override
            public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {
                i++;
                progressstatus(i);
            }

            @Override
            public void onLoadingCancelled(String imageUri, View view) {
                progressBar.setVisibility(View.GONE);

            }
        });

使用以下depth：

compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.5'

StorageReference mStorageRef = FirebaseStorage.getInstance().getReference();
