Link two tables in firebase using Id in android studio using Java

have a problem, I'm working on a university project, I have two tables in firebase, the gallery table that contains the photos of the itinerary and the itinerary table that contains the various itineraries of the users now I have to make sure that the id of the itinerary and the ID of the image so as to have a photo corresponding to each itinerary ì, also created by the same user. I did so:
public void addImageItinerary() {
storageReference = FirebaseStorage.getInstance().getReference();
referenceDb = FirebaseDatabase.getInstance().getReference();
firestore = FirebaseFirestore.getInstance();
auth = FirebaseAuth.getInstance();
if (images != null) {
StorageReference itineraryRef = storageReference.child("itinerary_image/" + FirebaseAuth.getInstance().getCurrentUser().getUid() + ".jpg");
itineraryRef.putFile(images).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {
#Override
public void onComplete(#NonNull Task<UploadTask.TaskSnapshot> task) {
if (task.isSuccessful()) {
itineraryRef.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
#Override
public void onSuccess(Uri uri) {
String itineraryId = referenceDb.child("Itinerary").push().getKey();
Log.i("itineraryId", itineraryId);
HashMap<String, Object> map = new HashMap<>();
map.put("image", uri.toString());
referenceDb.child("Gallery").child(FirebaseAuth.getInstance().getCurrentUser().getUid()+ "/" + itineraryId).setValue(map).addOnCompleteListener(new OnCompleteListener<Void>() {
#Override
public void onComplete(#NonNull Task<Void> task) {
if (task.isSuccessful()) {
// APRO SCHERMATA MAPPA
// openMapFragment();
Toast.makeText(insertImage_fragment.getActivity(), "ok", Toast.LENGTH_SHORT).show();
} else {
//ERRORE
Toast.makeText(insertImage_fragment.getActivity(), "Operation failed. Please try again", Toast.LENGTH_SHORT).show();
}
}
});
}
});
} else {
Toast.makeText(insertImage_fragment.getActivity(), task.getException().toString(), Toast.LENGTH_SHORT).show();
}
}
});
} else{
Toast.makeText(insertImage_fragment.getActivity(),"Please add image", Toast.LENGTH_SHORT).show();
}
}

Unable to download Images from Firebase Storage

I am trying to download the profile picture from firebase whose name is set as the userID of the user. I am using the glide library to download the images but I am getting a StorageException: StorageException has occurred. Object does not exist at location. error.
Here is my code
String uid = user.getUid();
storageReference.child("ProfilePictures").child(uid).getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
#Override
public void onSuccess(Uri uri) {
// Got the download URL for 'users/me/profile.png'
Log.d("TAG" , "URI = "+uri);
GlideApp.with(context).load(uri).into(profilepic);
//profilepic.setImageURI(uri);
}
}).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception exception) {
// Handle any errors
Toast.makeText(getApplicationContext(), "Error getting Profile Picture", Toast.LENGTH_LONG).show();
}
});
}
#Override
public void onCancelled(DatabaseError databaseError) {}
});
My Database
Declaration of storageReference
StorageReference storageReference;
storageReference = FirebaseStorage.getInstance().getReference();

Change this:
storageReference.child("ProfilePictures").child(uid).getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
#Override
into this:
storageReference.child("ProfilePictures").child(uid + ".jpg").getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
#Override

public StorageReference mStorageRef;
StorageReference particular_image;
private FirebaseDatabase firebasedatabase;
private DatabaseReference databasereference;
oncreate()
{
mStorageRef = FirebaseStorage.getInstance().getReference().child("give");
firebasedatabase = FirebaseDatabase.getInstance(); //1st time is imp.
databasereference = firebasedatabase.getReference().child("giver_data");
particular_image.putFile(photoURI).addOnSuccessListener
(this, new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
final Uri download_uri = taskSnapshot.getDownloadUrl();
Glide.with(getApplicationContext())
.load(p_l.getPhotoUrl()).asBitmap().override(view.getMaxWidth(),view.getMaxHeight()).error(R.drawable.ic_selfie_point_icon) //asbitmap after load always.
.into(new SimpleTarget<Bitmap>() {
#Override
public void onResourceReady(Bitmap resource, GlideAnimation<? super Bitmap> glideAnimation) {
Bitmap d = new BitmapDrawable(resource).getBitmap();
int nh = (int) ( d.getHeight() * (512.0 / d.getWidth()) );
Bitmap scaled = Bitmap.createScaledBitmap(d, 512, nh, true);
//holder.food_img.setImageBitmap(scaled);
view.setImageBitmap(scaled);
}
});
//getting uri of the image stored
//Photo_link p_link =newPhoto_link(download_uri.toString());
// databasereference.push().setValue(p_link);
//String uri_string = download_uri.toString();
pb.clearAnimation();
pb.clearFocus();
// animation.end();
Intent i = new Intent(getApplicationContext(),Giver_Edit.class);
i.setData(download_uri);
startActivity(i);
Toast.makeText(getApplicationContext(),"Food Image Uploaded successfully",Toast.LENGTH_SHORT).show();
Log.d("giver_image_success","no eroooooor_on_success");
//Toast.makeText(getApplicationContext(),"Image added",Toast.LENGTH_LONG).show();
}
});
// final Uri selectedImgUri = getIntent().getData();
particular_image.putFile(uri).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Log.d("giver_image_failure","eroooooor_on_ffailure");
Toast.makeText(getApplicationContext(), e.getMessage(), Toast.LENGTH_SHORT).show();
}
});
And now this should solve your problem! Make sure to upvote if helpful and comment if doubt!
Note: Instead of my code function of UploadTask use your onSuccess() which you had mentioned in the code.

Make sure if you're allowed to users to access Storage with this Rule :
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write: if true;
}
}
}
Put this in you're dependencies :
dependencies {
// FirebaseUI Storage only
implementation 'com.firebaseui:firebase-ui-storage:4.3.1'
}
Now Get Image from storage :
StorageReference storageReference= FirebaseStorage.getInstance().getReference().child("ProfilePictures/"+uid+".jpg"); // if you know how to use this you can get image directly without doing that big query
//Following line will be useful when you try to get image from storage
GlideApp.with(this /* context */)
.load(storageReference)
.into(imageView);
For further information you can read docs or just comment me if any issue occur

I want to retrieve videos from firebase storage

I am working on simple firebase app in which I upload user info as registration data and uploading videos in storage. Path of videos is also stored in realtime database as nested child of every particular user which is working properly, but I don't know how to retrieve video and set in user profile with other user information.

Saving the Firebase storage.getDownloadURL() to Firebase Database [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();
}

//Firebase Storage - Easy to Working with uploads and downloads.
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable final Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == RC_SIGN_IN){
if(resultCode == RESULT_OK){
Toast.makeText(this,"Signed in!", LENGTH_SHORT).show();
} else if(resultCode == RESULT_CANCELED){
Toast.makeText(this,"Signed in canceled!", LENGTH_SHORT).show();
finish();
}
} else if(requestCode == RC_PHOTO_PICKER && resultCode == RESULT_OK){
// HERE I CALLED THAT METHOD
uploadPhotoInFirebase(data);
}
}
private void uploadPhotoInFirebase(#Nullable Intent data) {
Uri selectedImageUri = data.getData();
// Get a reference to store file at chat_photos/<FILENAME>
final StorageReference photoRef = mChatPhotoStorageReference
.child(selectedImageUri
.getLastPathSegment());
// Upload file to Firebase Storage
photoRef.putFile(selectedImageUri)
.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
// Download file From Firebase Storage
photoRef.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
#Override
public void onSuccess(Uri downloadPhotoUrl) {
//Now play with downloadPhotoUrl
//Store data into Firebase Realtime Database
FriendlyMessage friendlyMessage = new FriendlyMessage
(null, mUsername, downloadPhotoUrl.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 compress image while uploading to the firebase?

i am working on the a social app where the user can upload their image on their feeds but when the user is picking up the image ,the image less than 2 mb are getting picked up and are successfully uploaded to the firebase but when the user uploads the image more than 2mb the app crashes. what can be done to compress the image ..

You can then upload to firebase with the this code:

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) {

});

You can create bitmap with captured image as below:
Bitmap bitmap = Bitmap.createScaledBitmap(yourimageuri, width, height, true);// the uri you got from onactivityresults
