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();
}
//Firebase Storage - Easy to Working with uploads and downloads.
#Override

super.onActivityResult(requestCode, resultCode, data);

// Get a reference to store file at chat_photos/<FILENAME>
final StorageReference photoRef = mChatPhotoStorageReference

photoRef.putFile(selectedImageUri)

//Store data into Firebase Realtime Database

}
here i am uploading and getting the image url at the same time...
final StorageReference profileImageRef = FirebaseStorage.getInstance().getReference("profilepics/" + System.currentTimeMillis() + ".jpg");

profileImageRef.getDownloadUrl().addOnCompleteListener(new OnCompleteListener<Uri>() {

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,

.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);
}
});
}

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);
}
});
}
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();
}

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 ->

task.exception?.let {

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,

} 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);
}
});
}
