I am trying to store the url in the firebasedatabase of images i upload into the firebase storage.

I have tried some video guides but most of them are outdated.I am trying to use downloadUrl to fetch url but its not working. I am new to coding and i d appreciate any kind of advice. I have tried Firebase Documentation but i am unable to apply it into my code.

 if (mImageUri != null) { val fileName= edit_text_file_name.text.toString() val fileReference = mStorageRef!!.child(fileName + "." + getFileExtension(mImageUri!!) ) mUploadTask = fileReference.putFile(mImageUri!!) .addOnSuccessListener { taskSnapshot -> val name = taskSnapshot.metadata!!.name val imageUrl= taskSnapshot.metadata!!.reference!!.downloadUrl.toString()

The problem here is in the line above i think with val imageUrl 

 writeNewImageInfoToDB(name!!, imageUrl) Toast.makeText(this@ActivityUpload, "Upload successful", Toast.LENGTH_LONG).show() } .addOnFailureListener { e -> Toast.makeText(this@ActivityUpload, e.message, Toast.LENGTH_SHORT).show() } .addOnProgressListener { taskSnapshot -> val progress = (100.0 * taskSnapshot.bytesTransferred / taskSnapshot.totalByteCount) mProgressBar!!.progress = progress.toInt() }

I expect the above code to give me the URL of the image i uploaded but instead i get

com.google.android.gms.tasks.zzu@5a826e5" in my database whereas i am expecting a firebase url like firebasestorage.googleapis.com/v0/b/-------`

You are getting:

com.google.android.gms.tasks.zzu@5a826e5

And not the actual url because this is the address from memory of your downloadUrl object which is of type Task<Uri> and not the actual Uri.

According to the official documentation regarding on how to get a download URL:

After uploading a file, you can get a URL to download the file by calling the getDownloadUrl() method on the StorageReference:

val ref = storageRef.child(fileName + "." + getFileExtension(mImageUri!!)) uploadTask = ref.putFile(file) val urlTask = uploadTask.continueWithTask(Continuation<UploadTask.TaskSnapshot, Task<Uri>> { task -> if (!task.isSuccessful) { task.exception?.let { throw it } } return@Continuation ref.downloadUrl }).addOnCompleteListener { task -> if (task.isSuccessful) { val downloadUri = task.result } else { // Handle failures // ... } }

Where is the urlTask used?
Inside the onComplete() function. Does it work this way?
This method worked out for me, i had to make adjustments to my code. I was just confused about the useage of the val urlTask...
still didn't work for me...
