private void Upload() { if (mimgUrl.= null) { StorageReference fileReference = storageReference.child(System.currentTimeMillis() + ";" + getFileExtension(mimgUrl));

        mUploadTask = fileReference.putFile(mimgUrl)
                .addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                    @Override
                    public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                        Handler handler = new Handler();
                        handler.postDelayed(new Runnable() {
                            @Override
                            public void run() {
                                progressBar.setProgress(0);
                            }

                        Upload upload = new Upload(etFile.getText().toString().trim(),
                                taskSnapshot.getMetadata().getReference().getDownloadUrl().toString());
                        String uploadId = databaseReference.push().getKey();
                        databaseReference.child(uploadId).setValue(upload);
                    }
                })
                .addOnFailureListener(new OnFailureListener() {
                    @Override
                    public void onFailure(@NonNull Exception e) {
                        Toast.makeText(upload_iklan.this, e.getMessage(), Toast.LENGTH_SHORT).show();
                    }
                })
                .addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
                    @Override
                    public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
                        double progress = (100.0 * taskSnapshot.getBytesTransferred() / taskSnapshot.getTotalByteCount());
                        progressBar.setProgress((int) progress);
                    }
                });
    } else {
        Toast.makeText(this, "No file selected", Toast.LENGTH_SHORT).show();
    }
}

Answer 1

Welcome to Stack Overflow:)

By default, your firebase storage rules requires your user to be logged in before you can upload any files.

So, if you want to upload a picture successfully, either log in with a user in your android app or allow unauthenticated users to upload to the console like this:

1. Go to your Firebase Console
2. Click Storage
3. Click Rules
4. Change your rules file to this:

service firebase.storage {
  match /b/{bucket}/o {
    match /{allPaths=**} {
      //allow read, write: if request.auth != null;
      allow read, write
    }
  }
}

Answer 2

Change the rules of storage in firebase.

1. Go to firebase console

2. Click on Storage

3. Click Rules

4. Edit rules to the rule given below

   rules_version = '2'; service firebase.storage { match /b/grocery-e7c47.appspot.com/o { match /{allPaths=**} { allow read, write: if request.auth;= null; } } }
