Answer 1

To upload the image to Firebase storage, add an android service into your manifest.xml Below was a sample android service added:-

<service
       android:name=".service.ImageUploadService"
       android:exported="false" />

The demo and source code were provided by Firebase here: https://github.com/firebase/quickstart-android/tree/master/storage

Answer 2

It's a logical bug, as you are checking when title & description is empty only then upload the image. So change your code as done below-

if(!TextUtils.isEmpty(title)  && !TextUtils.isEmpty(description) && uri!=null) {
    StorageReference filepath = reference.child("images/"+ UUID.randomUUID().toString());
    filepath.putFile(uri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
            Toast.makeText(Add_Post.this, "Uploaded", Toast.LENGTH_SHORT).show();
            pd.dismiss();
        }
    });
}
