Question

In my new android firebase project, I used com.google.firebase:firebase-storage:16.0.1 library.

I get the following Error:

I opened ano

Answer 1

That method has been deprecated on version 16.0.1 (check Firebase release notes) so you have to use

StorageReference.getDownloadUrl()

If you want to get them after uploading the file, then you must check their documentation here. It is already updated.

Answer 2

taskSnapshot.getDownloadUrl() is deprecated so i recommend that in your addOnSuccessListener() method, you use your storageReference and call the getDownloadUrl() method in order to get the url of the file and you can do whatever you want with it. Hope it helps.

         mUploadTask = storageRef.putFile(file).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
            @Override
            public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {

                // get the image Url of the file uploaded
                storageRef.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
                    @Override
                    public void onSuccess(Uri uri) {
                        // getting image uri and converting into string
                        Uri downloadUrl = uri;
                       fileUrl = downloadUrl.toString();


                    }
                });

            }
        });

Answer 3

that's how I'm getting download link in kotlin android.

 ref.putFile(filePath!!)
            .addOnSuccessListener {
            val result = it.metadata!!.reference!!.downloadUrl;
            result.addOnSuccessListener {

               val imageLink = it.toString()


            }
        }

Answer 4

In this case is better to continue using addOnSuccessListener as you're using, but instead of using getDownloadUrl directly, you need to add a listener to that too.

Now the method is inside taskSnapshot.getMetadata().getReference() like this

filePath.putFile(imageUri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
            @Override
            public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                 taskSnapshot.getMetadata().getReference().getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
                    @Override
                    public void onSuccess(Uri uri) {
                        // User uri here
                    }
                });
            }

        });

Answer 5

Firebase upadated their method so kindly update yourself use this method kindly:

this is the basic line at which you feeling annoying, very simple justget the download path in this way

 StorageReference ref = storageReference.child("images/"+ UUID.randomUUID().toString());
  UploadTask  uploadTask = ref.putFile(filePath);
  Task<Uri> urlTask = 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();
     }

                                                              // Continue with the task to get the download URL
     return ref.getDownloadUrl();
   }
 }).addOnCompleteListener(new OnCompleteListener<Uri>() {
    @Override
    public void onComplete(@NonNull Task<Uri> task) {
      if (task.isSuccessful()) {
        Uri downloadUri = task.getResult();


    ///here is your image url enjoy this 

          Toast.makeText(CloudStorageActivity.this, "Uploaded", Toast.LENGTH_SHORT).show();

        }


      } else {


        // Handle failures
        // ...
      }
    }
  });

I had Found 2 solution for my issue.

Firebase Google Documentation :

//add file on Firebase and got Download Link
filePath.putFile(imageUri).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 filePath.getDownloadUrl();
    }
}).addOnCompleteListener(new OnCompleteListener<Uri>() {
    @Override
    public void onComplete(@NonNull Task<Uri> task) {
        if (task.isSuccessful()){
            Uri downUri = task.getResult();
            Log.d(TAG, "onComplete: Url: "+ downUri.toString());
        }
    }
});

Another solution!

It's more easy and small than google Firebase documentation and I'll use it:

filePath.putFile(imageUri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
    @Override
    public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
        filePath.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
            @Override
            public void onSuccess(Uri uri) {
                Log.d(TAG, "onSuccess: uri= "+ uri.toString());
            }
        });
    }
});
