Develop Reference

error showing downloadUrl might not have been initialized [duplicate]

I'm trying to get the "long term persistent download link" to files in our Firebase storage bucket.
I've changed the permissions of this to
service firebase.storage {
match /b/project-xxx.appspot.com/o {
match /{allPaths=**} {
allow read, write;
}
}
}
And my javacode looks like this:
private String niceLink (String date){
String link;
// Points to the root reference
StorageReference storageRef = FirebaseStorage.getInstance().getReference();
StorageReference dateRef = storageRef.child("/" + date+ ".csv");
link = dateRef.getDownloadUrl().toString();
return link;
}
When I run this I get the uri link that looks something like
com.google.android.gms.tasks.zzh#xxx
Question 1. Can I from this get the download link similar to: https://firebasestorage.googleapis.com/v0/b/project-xxxx.appspot.com/o/20-5-2016.csv?alt=media&token=b5d45a7f-3ab7-4f9b-b661-3a2187adxxxx
When trying to get the link above I changed the last row before my return, like this:
private String niceLink (String date){
String link;
// Points to the root reference
StorageReference storageRef = FirebaseStorage.getInstance().getReference();
StorageReference dateRef = storageRef.child("/" + date+ ".csv");
link = dateRef.getDownloadUrl().getResult().toString();
return link;
}
But when doing this i get a 403 error, and the app crashing. The consol tells me this is bc user is not logged in /auth.
"Please sign in before asking for token"
Question 2. How do I fix this?

Please refer to the documentation for getting a download URL.
When you call getDownloadUrl(), the call is asynchronous and you must subscribe on a success callback to obtain the results:
// Calls the server to securely obtain an unguessable download Url
private void getUrlAsync (String date){
// Points to the root reference
StorageReference storageRef = FirebaseStorage.getInstance().getReference();
StorageReference dateRef = storageRef.child("/" + date+ ".csv");
dateRef.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>()
{
#Override
public void onSuccess(Uri downloadUrl)
{
//do something with downloadurl
}
});
}
This will return a public unguessable download url. If you just uploaded a file, this public url will be in the success callback of the upload (you do not need to call another async method after you've uploaded).
However, if all you want is a String representation of the reference, you can just call .toString()
// Returns a Uri of the form gs://bucket/path that can be used
// in future calls to getReferenceFromUrl to perform additional
// actions
private String niceRefLink (String date){
// Points to the root reference
StorageReference storageRef = FirebaseStorage.getInstance().getReference();
StorageReference dateRef = storageRef.child("/" + date+ ".csv");
return dateRef.toString();
}

mDatabaseReference.push().setValue(friendlyMessage);
}
});
}
});
}

here i am uploading and getting the image url at the same time...
final StorageReference profileImageRef = FirebaseStorage.getInstance().getReference("profilepics/" + System.currentTimeMillis() + ".jpg");
if (uriProfileImage != null) {
profileImageRef.putFile(uriProfileImage)
.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
// profileImageUrl taskSnapshot.getDownloadUrl().toString(); //this is depreciated
//this is the new way to do it
profileImageRef.getDownloadUrl().addOnCompleteListener(new OnCompleteListener<Uri>() {
#Override
public void onComplete(#NonNull Task<Uri> task) {
String profileImageUrl=task.getResult().toString();
Log.i("URL",profileImageUrl);
}
});
}
})
.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
progressBar.setVisibility(View.GONE);
Toast.makeText(ProfileActivity.this, "aaa "+e.getMessage(), Toast.LENGTH_SHORT).show();
}
});
}

For me, I did my code in Kotlin and I had the same error "getDownload()". Here are both the dependencies that worked for me and the Kotlin code.
implementation 'com.google.firebase:firebase-storage:18.1.0' firebase storage dependencies
This what I added and it worked for me in Kotlin. Storage() would come before Download()
profileImageUri = taskSnapshot.storage.downloadUrl.toString()

StorageReference mStorageRef = FirebaseStorage.getInstance().getReference();
final StorageReference fileupload=mStorageRef.child("Photos").child(fileUri.getLastPathSegment());
UploadTask uploadTask = fileupload.putFile(fileUri);
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();
}
return ref.getDownloadUrl();
}
}).addOnCompleteListener(new OnCompleteListener<Uri>() {
#Override
public void onComplete(#NonNull Task<Uri> task) {
if (task.isSuccessful()) {
Uri downloadUri = task.getResult();
Picasso.get().load(downloadUri.toString()).into(image);
} else {
// Handle failures
}
}
});

Clean And Simple
private void putImageInStorage(StorageReference storageReference, Uri uri, final String key) {
storageReference.putFile(uri).addOnCompleteListener(MainActivity.this,
new OnCompleteListener<UploadTask.TaskSnapshot>() {
#Override
public void onComplete(#NonNull Task<UploadTask.TaskSnapshot> task) {
if (task.isSuccessful()) {
task.getResult().getMetadata().getReference().getDownloadUrl()
.addOnCompleteListener(MainActivity.this,
new OnCompleteListener<Uri>() {
#Override
public void onComplete(#NonNull Task<Uri> task) {
if (task.isSuccessful()) {
FriendlyMessage friendlyMessage =
new FriendlyMessage(null, mUsername, mPhotoUrl,
task.getResult().toString());
mFirebaseDatabaseReference.child(MESSAGES_CHILD).child(key)
.setValue(friendlyMessage);
}
}
});
} else {
Log.w(TAG, "Image upload task was not successful.",
task.getException());
}
}
});
}

The getDownloadUrl method was removed in firebase versions greater than 11.0.5
I recommend using version 11.0.2 that still uses this method.

The getDownloadUrl method has now been depreciated in the new firebase update. Instead use the following method.
taskSnapshot.getMetadata().getReference().getDownloadUrl().toString()

change the received URI to URL
val urlTask = uploadTask.continueWith { task ->
if (!task.isSuccessful) {
task.exception?.let {
throw it
}
}
spcaeRef.downloadUrl
}.addOnCompleteListener { task ->
if (task.isSuccessful) {
val downloadUri = task.result
//URL
val url = downloadUri!!.result
} else {
//handle failure here
}
}

You can Upload images to firestore and get it's download URL as below function:
Future<String> uploadPic(File _image) async {
String fileName = basename(_image.path);
StorageReference firebaseStorageRef = FirebaseStorage.instance.ref().child(fileName);
StorageUploadTask uploadTask = firebaseStorageRef.putFile(_image);
var downloadURL = await(await uploadTask.onComplete).ref.getDownloadURL();
var url =downloadURL.toString();
return url;
}

Also you can do as follows In latest Firebase_storage version nullsafe,
//Import
import 'package:firebase_storage/firebase_storage.dart' as firebase_storage;
Future<void> _downloadLink(firebase_storage.Reference ref) async {
//Getting link make sure call await to make sure this function returned a value
final link = await ref.getDownloadURL();
await Clipboard.setData(ClipboardData(
text: link,
));
ScaffoldMessenger.of(context).showSnackBar(
const SnackBar(
content: Text(
'Success!\n Copied download URL to Clipboard!',
),
),
);
}

implementation 'com.google.firebase:firebase-storage:19.2.0'
Recently getting url from upload task wasn't working so I tried this and worked for me on above dependency.
So inside where you use firebase upload method use this.
filepath is the reference of Firebase Stoarage.
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());
}
});
}
});

private void getDownloadUrl(){
FirebaseStorage storage = FirebaseStorage.getInstance();
StorageReference storageRef = storage.getReference();
StorageReference imageRef = storageRef.child("image.jpg");
imageRef.getDownloadUrl().addOnCompleteListener(new OnCompleteListener<Uri>() {
#Override
public void onComplete(#NonNull Task<Uri> task) {
String profileimageurl =task.getResult().toString();
Log.e("URL",profileimageurl);
ShowPathTextView.setText(profileimageurl);
}
});
}

How to get Firebase Storage image URL in android studio?

I want to display image on imageView from Firebase Storage without saving the picture in the device, so I've tried to use the highlighted URL (from the photo below) and it works but I don't want to write the address manually.
How can I get the address using the code?
p.s I tried dataBaseStorageRef.getDownloadUrl() and it gives me another URL, not the one from the picture.
enter image description here
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
final StorageReference filePath = storage.child("books").child(""+AddBook.book_id+1).child("photo.jpg");
if(requestCode == RESULT_GALLERY){
if (resultCode == RESULT_OK){
pic_uri = data.getData();
book_img.setImageURI(pic_uri);
filePath.putFile(pic_uri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
Toast.makeText(AddBookActivity.this, "Upload done", Toast.LENGTH_SHORT).show();
}
}).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Toast.makeText(AddBookActivity.this, "Failed to upload!", Toast.LENGTH_SHORT).show();
}
});
img_addr = filePath.getDownloadUrl().toString();
Toast.makeText(this, "picture was selected", Toast.LENGTH_SHORT).show();
}
}
}
Then, I'm trying to display the pic from img_addr from another activity
and it doesn't work because the address of image_addr is not good (if I replace manually img_addr to the address from the attached link it works)
if(books_list.get(i).img_addr!=null){
Toast.makeText(v.getContext(),books_list.get(i).img_addr,Toast.LENGTH_LONG).show();
Picasso.with(v.getContext()).load(books_list.get(i).img_addr).resize(50,50).into(img);
}
Thanks to those who help

You can use continueWithTask method to return the download url
Like the following:
final UploadTask uploadTask = filepath.putFile(uri);
uploadTask.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
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 filepath.getDownloadUrl();
}
}).addOnCompleteListener(new OnCompleteListener<Uri>() {
#Override
public void onComplete(#NonNull Task<Uri> task) {
if (task.isSuccessful()) {
thumb_download_url = task.getResult().toString();
}
}
});
}
}).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
}
});

Make getDownloadUrl() asynchronous by adding onsuccess and onfailure listeners to it.
Your complete image upload task should look like below
photoReference.putFile(imageUri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
photoReference.getDownloadUrl().addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
//do something
}
}).addOnSuccessListener(new OnSuccessListener<Uri>() {
#Override
public void onSuccess(Uri uri) {
//get your image uri here
Uri imgUrl = uri;
String imgStringUrl = imgUrl.toString();
}
});
}
}).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
// do something
}
});

You can get download URL from below method:
private void uploadToStorage(String imgPath, String fileName) {
Uri file = Uri.fromFile(new File(imgPath));
StorageReference storageReference = mStorageRef.child(userId + "/images/" + fileName);
storageReference.putFile(file).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
Task<Uri> downloadUrl = taskSnapshot.getStorage().getDownloadUrl();
downloadUrl.addOnCompleteListener(new OnCompleteListener<Uri>() {
#Override
public void onComplete(#NonNull Task<Uri> task) {
Log.v(TAG, "Media is uploaded");
String downloadURL = "https://" + task.getResult().getEncodedAuthority()
+ task.getResult().getEncodedPath()
+ "?alt=media&token="
+ task.getResult().getQueryParameters("token").get(0);
Log.v(TAG, "downloadURL: " + downloadURL);
//save your downloadURL
}
});
}
}).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception exception) {
Log.v(TAG, "Media is not uploaded");
Log.v(TAG, "Exception: " + exception.getLocalizedMessage());
}
});
}
You can also get scheme name & query from methods under task.getResult()

getDownloadUri() in Firebase Storage is deprecated or cannot resolve [duplicate]

To upload images to Firebase Storage I am attaching addOnSuccessListener on the instance of the StorageReference. While overriding onSuccess method I am calling getDownloadUrl() on the instance of taskSnapshot but it is giving me an error saying
Can't resolve method getDownloadUrl()
This app I had created 2 months ago, earlier this app was working fine and getDownloadUrl() was working fine as well. Also, in taskSnapshot instance when I press Ctrl+space, in the suggestions I don't find getDownloadUrl() method. Why is it happening?

The Firebase API has changed.
May 23, 2018
Cloud Storage version 16.0.1
Removed the deprecated StorageMetadata.getDownloadUrl() and UploadTask.TaskSnapshot.getDownloadUrl() methods. To get a current download URL, use StorageReference.getDownloadUr().
UploadTask.TaskSnapshot has a method named getMetadata() which returns a StorageMetadata object.
This StorageMetadata object contains a method named getReference() which returns a StorageReference object.
That StorageReference object contains the getDownloadUrl() method, which now returns a Task object instead of an Uri object.
This Task must then be listened upon in order to obtain the Uri, which can be done asynchronously or in a blocking manner; see the Tasks API for that.

You wont get the download url of image now using
profileImageUrl = taskSnapshot.getDownloadUrl().toString();
this method is deprecated.
Instead you can use the below method
uniqueId = UUID.randomUUID().toString();

Issues uploading photos with Firebase

I'm having trouble uploading an image over firebase.
Here's the code:
//...
//Storage
mFirebaseStorage = FirebaseStorage.getInstance();
mUserphotos = mFirebaseStorage.getReference().child("user/#userID");
mTestphotos = mFirebaseStorage.getReference().child("user/testPhotos");
//...
public void uploadImage(Uri uri) {
Uri file = Uri.fromFile(new File("user/testPicture"));
StorageReference testPath = mTestphotos.child("images/"+file.getLastPathSegment());
UploadTask uploadTask = testPath.putFile(file);
// Register observers to listen for when the download is done or if it fails
uploadTask.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception exception) {
// Handle unsuccessful uploads
Toast.makeText(MainActivity.this, "failure", Toast.LENGTH_SHORT).show();
}
}).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
// taskSnapshot.getMetadata() contains file metadata such as size, content-type, and download URL.
Uri downloadUrl = taskSnapshot.getDownloadUrl();
Toast.makeText(MainActivity.this, "It worked", Toast.LENGTH_SHORT).show();
}
});
//...
To save time yes I am sure the uri is getting the correct photo. There is also more to the uploadImage

//getting the storage reference
// filePath is Uri
// "uploads/" is STORAGE_PATH_UPLOADS
StorageReference sRef = storageReference.child("uploads/" + System.currentTimeMillis() + "." + getFileExtension(filePath));
//adding the file to reference
sRef.putFile(filePath)
.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
//displaying success toast
Toast.makeText(getApplicationContext(), "File Uploaded ", Toast.LENGTH_LONG).show();
//creating the upload object to store uploaded image details
Upload upload = new Upload(editTextName.getText().toString().trim(), taskSnapshot.getDownloadUrl().toString());
//adding an upload to firebase database
String uploadId = mDatabase.push().getKey();
mDatabase.child(uploadId).setValue(upload);
}
})
.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception exception) {
progressDialog.dismiss();
Toast.makeText(getApplicationContext(), exception.getMessage(), Toast.LENGTH_LONG).show();
}
})
.addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
#Override
public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
//displaying the upload progress
double progress = (100.0 * taskSnapshot.getBytesTransferred()) / taskSnapshot.getTotalByteCount();
progressDialog.setMessage("Uploaded " + ((int) progress) + "%...");
}
});

Try this,
Uri uri = data.getData() ;// your image uri
StorageReference imagePathReference = StorageRef.child("Your path");
Bitmap bmp = null;
try {
bmp = MediaStore.Images.Media.getBitmap(getContentResolver(), data.getData());
} catch (IOException e) {
e.printStackTrace();
}
// convert bitmap to byte array to save image in firebase storage
ByteArrayOutputStream bos = new ByteArrayOutputStream();
if (bmp != null) {
bmp.compress(Bitmap.CompressFormat.JPEG, 60, bos);
}
