How to get URL from Firebase Storage getDownloadURL

Question

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 fireb         


        

Answer 1

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.

//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);
                        }
                    });
                }
            });
}

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;

  }

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
            }
       }
});
