Hello everyone. I am going to make a notes app and I want to add to note images ,videos. But I do not know what better to choose for that, RecyclerView or just create one editText field, add Scrollview and use SpannableStringBuilder. I tried two ways and in both ways I had problems. Now I made notes app by SpannableStringBuilder and in my note I can add only text and image. I keep notes in SQLite. Every thing works good but I have a one problem. I do not know how to add one more element to my note , for exemple video. If somebody has done it before please help me. I need to know with what better way to do it.
Thank you
