How to upload an image to Firebase storage?

Question

I'm trying to upload a simple byte array into Firebase storage, but my onFailureListener keeps getting called and logging back to me saying that the upload failed. I'm hoping you guys can tell me whats wrong with my code.

At the top I got

 //Firebase
    private Firebase mRef;
    private StorageReference storageRef;

Then in onStart()

@Override
protected void onStart() {
    super.onStart();
    googleApiClient.connect();
    //Firebase
    mRef = new Firebase("link to firebase account");
    FirebaseStorage storage = FirebaseStorage.getInstance();
    storageRef = storage.getReferenceFromUrl("link to storage");

}

Then in my onActivityResult()

      @Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            addImageImageView.setVisibility(View.GONE);
            if (requestCode == Constants.REQUEST_CODE && resultCode == RESULT_OK && data != null) {
                //First we gotta make sure to add the images to
                ArrayList<Image> imagesFromGallery = data.getParcelableArrayListExtra(Constants.INTENT_EXTRA_IMAGES);
                for (int i = 0; i < imagesFromGallery.size(); i++) 
                {
                    try {
                        //try uploading it
                        InputStream stream = new FileInputStream(new File(imagesFromGallery.get(i).path));
                        StorageReference imageStorage = storageRef.child("cardImages/" + "testImages");
                        UploadTask uploadTask = imageStorage.putStream(stream);
                        uploadTask.addOnFailureListener(new OnFailureListener() {
                        @Override
                        public void onFailure(@NonNull Exception e) {
                            Log.d("myStorage","failure :(");
                        }
                    }).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                        @Override
                        public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                            Log.d("myStorage","success!");
                        }
                    });
                    catch (UnsupportedEncodingException e) {
                    e.printStackTrace();
                    } catch (FileNotFoundException e) {
                     e.printStackTrace();
                }
           }
      }

Here is my stack trace:

In `onFailure()`, add `e.getMessage()` to the log message to see the reason for the exception. — Bob Snyder, Nov 14 '16 at 05:22
The [documentation](https://firebase.google.com/docs/storage/android/upload-files) explains that the default security rules for Firebase Storage require authentication. Have you signed-in the user or changed the rules to allow public access? — Bob Snyder, Nov 14 '16 at 05:29

You either need to sign-in the user or change the security rules to allow public access. This is explained in the documentation for Firebase Storage Security.

For initial development, you can change the rules at the Firebase Console to allow public access:

service firebase.storage {
  match /b/project-XXXXXXXXXXXXXX.appspot.com/o {
    match /{allPaths=**} {
      // Provide access to all users
      allow read: if true;
      allow write: if true;
    }
  }
}

You wrote : "... match /b/project-XXXXXXXXXXXXXX.appspot.com/o {...". Must I put in the project package name or project's so called Public-facing name. Mine is project-xxxxxxxx? – CodeToLife Apr 11 '19 at 12:47

@CodeToLife: It looks like things have changed since I wrote this answer. Originally, the Project ID (shown on General tab of Project Settings) was used. Now it looks like you can use `{bucket}`. See the [sample rules](https://firebase.google.com/docs/storage/security/start#sample-rules) for an example. – Bob Snyder Apr 11 '19 at 13:21

I upload images using this code :

private void uploadFile(Bitmap bitmap) {
            FirebaseStorage storage = FirebaseStorage.getInstance();
            StorageReference storageRef = storage.getReferenceFromUrl("Your url for storage");
            StorageReference mountainImagesRef = storageRef.child("images/" + chat_id + Utils.getCurrentTimeStamp() + ".jpg");
            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            bitmap.compress(Bitmap.CompressFormat.JPEG, 20, baos);
            byte[] data = baos.toByteArray();
            UploadTask uploadTask = mountainImagesRef.putBytes(data);
            uploadTask.addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception exception) {
                    // Handle unsuccessful uploads
                }
            }).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();
                    sendMsg("" + downloadUrl, 2);
                    Log.d("downloadUrl-->", "" + downloadUrl);
                }
            });

        }

Dependency :

Project Level Gradel : classpath 'com.google.gms:google-services:3.0.0'

App Level Gradel : compile 'com.google.firebase:firebase-storage:9.0.2'

do you know if, in app gradle we need to include anything for firebase storage? — TheQ, Nov 14 '16 at 04:55
In project level gradel we have require to classpath 'com.google.gms:google-services:3.0.0' and app level gradel we have require compile 'com.google.firebase:firebase-storage:9.0.2' define — Dhaval Solanki, Nov 14 '16 at 04:59

Simply call this method to store your image to firebase.

 private void storeImageToFirebase() {
        BitmapFactory.Options options = new BitmapFactory.Options();
        options.inSampleSize = 8; // shrink it down otherwise we will use stupid amounts of memory
        Bitmap bitmap = BitmapFactory.decodeFile(mCurrentPhotoUri.getPath(), options);
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos);
        byte[] bytes = baos.toByteArray();
        String base64Image = Base64.encodeToString(bytes, Base64.DEFAULT);
       //For the API less than 28 (Android version 8 )
       //String base64Image = android.util.Base64.encodeToString(bytes, android.util.Base64.DEFAULT);


        // we finally have our base64 string version of the image, save it.
        firebase.child("pic").setValue(base64Image);
        System.out.println("Stored image with length: " + bytes.length);
    }

dont you need Upload task and StorageReference to put it in firebase storage? — TheQ, Nov 14 '16 at 04:40

this method worked for me as if todate:

private void uploadImage(Bitmap bitmap) {
    progressDialog.show();
    final StorageReference ref = storageReference.child("drivers/" + UserDto.getId() + ".jpg");

    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.JPEG, 20, baos);
    byte[] data = baos.toByteArray();

    final UploadTask uploadTask = ref.putBytes(data);
    uploadTask.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
            progressDialog.dismiss();
            Toast.makeText(ProfileActivity.this, "Uploaded", Toast.LENGTH_SHORT).show();

            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 downUri = task.getResult();
                        Log.d("Final URL", "onComplete: Url: " + downUri.toString());
                    }
                }
            });
        }
    }).addOnFailureListener(new OnFailureListener() {

            progressDialog.dismiss();

Upload multilple images to Firebase storage.

It is working for me.

using this library

  compile 'com.github.darsh2:MultipleImageSelect:3474549'

At the top

private StorageReference storageRef;
private FirebaseApp app;
private FirebaseStorage storage;

onCreate()

app = FirebaseApp.getInstance();
storage =FirebaseStorage.getInstance(app);

button click action

   Gallary.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {


                Intent intent = new Intent(ChatActivity.this, AlbumSelectActivity.class);
                intent.putExtra(Constants.INTENT_EXTRA_LIMIT, 10);
                startActivityForResult(intent, Constants.REQUEST_CODE);

            }
        });

Activity result

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == Constants.REQUEST_CODE && resultCode == RESULT_OK) {
        ArrayList<Image> images = data.getParcelableArrayListExtra(Constants.INTENT_EXTRA_IMAGES);
        Uri[] uri=new Uri[images.size()];
        for (int i =0 ; i < images.size(); i++) {
            uri[i] = Uri.parse("file://"+images.get(i).path);
            StorageReference ref = storage.getReference("photos").child(uri[i].getLastPathSegment());
            ref.putFile(uri[i])
                    .addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                        @Override
                        public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                            Uri downloadUrl = taskSnapshot.getDownloadUrl();
                            String content = downloadUrl.toString();

                        }
                    })
                    .addOnFailureListener(new OnFailureListener() {
                        @Override
                        public void onFailure(@NonNull Exception exception) {

                        }
                    })
                    .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) + "%...");
                        }
                    });

          }
        }

    }

@Nizamudeen Sherif i will send to the source code. Please give your mail id — Ansal Rabin, Jun 25 '18 at 10:15
