So, I code an android app, that takes pictures from facebook and stores them in a firebase db.

I use the graph-api to get the urls of the pictures, which works fine, since I can put the urls in a browser and the pictures appear.

Now I want to use an UploadTask to upload these pictures to firebase, and I get:

E/StorageException: StorageException has occurred.

    Object does not exist at location.

     Code: -13010 HttpResult: 404

    java.io.IOException: {  "error": {    "code": 404,    "message": "Not Found.  Could not get object"  }}

Here is my upload method:

static class UploadPicAsyncWrapperTask extends AsyncTask<String, Void, Void> {

            @Override

            protected Void doInBackground(String... strings) {



                String picsFolder = strings[0];

                String id = strings[1];

                final String url = strings[2];

                final String profilepicNodeName = strings[3];

                final String picsNodeName = strings[4];



                final StorageReference filePathRoot = FirebaseStorage.getInstance().getReference().child(picsFolder).child(FirebaseAuth.getInstance().getCurrentUser().getUid());

                final StorageReference filePath;



                filePath = filePathRoot.child(id);



                filePath.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {

                    @Override

                    public void onSuccess(Uri uri) {

                        // File already exists

                    }

                }).addOnFailureListener(new OnFailureListener() {

                    @Override

                    public void onFailure(@NonNull Exception exception) {



                        final UploadTask uploadTask;



                        try (InputStream is = new URL(Uri.encode(url)).openStream()) {

                            uploadTask = filePath.putStream(is); //Uri.fromFile(new File(url));  //Uri.parse(url) new ByteArrayInputStream()



                            uploadTask.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {

                                @Override

                                public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {

                                    filePath.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {

                                        @Override

                                        public void onSuccess(Uri uri) {

                                            if (profilePicName == null) {

                                                mUserDatabase.child(profilepicNodeName).setValue(uri.toString());

                                                profilePicName = uri.toString();



                                            } else {

                                                mUserDatabase.child(picsNodeName).child(Helper.imageUrlToFirebasePath(uri.toString())).setValue(uri.toString());

                                            }

                                            --picsRemaining;

                                        }

                                    });

                                }

                            });

                        } catch (MalformedURLException e) {

                            // TODO or not todo whatever

                        } catch (IOException e) {

                            // TODO or not todo whatever

                        }

                    }

                });



                return null;

            }

        }

And this is how the asyncTask is called:

new UploadPicAsyncWrapperTask().execute(getString(R.string.firebase_storage_pics_folder), id, url, getString(R.string.firebase_database_profilepic_node_name), getString(R.string.firebase_database_pics_node_name));

Anybody any idea why firebase can't catch the pictures?

So, there is nothing wrong with my code above. Since I can't ask Firebase if a picture was already uploaded to the database, I ask firebase to give me the downloadUrl of that picture and in onFailureListener, I upload the picture.

What I didn't know is, that onFailureListener implicit logs the error message above.
